PROFESSIONAL TRAINING IN ENTOMOLOGY*

BY M. A. STEWART

University of California, Berkeley

From time to time papers have been written and speeches have

been delivered concerning the teaching of entomology and com-

mittees have been appointed to study the problem of training

entomologists. However, little or no action has resulted from

these efforts to rationalize the professional education of entomolo-

gists and to develop reasonably uniform curricula of high stand-

ards comparable to those required of students in the older pro-

fessions. Curricula in entomology, even those generally regarded

as being among the best, have developed, in very large part at

least, more or less under the stimuli of personal interests of

prominent faculty members, rather than as the result of careful

and exhaustive studies of the legitimate demands upon, and the

responsibilities of, the profession of entomology and the conse-

quent needs of the student. No whole-hearted and successful at-

tempt has been made to standardize, within reasonable limits,

the curricula in entomology in the leading universities, which

should result ultimately in the adoption of similar programs of

study by the smaller and less well endowed institutions. As a

consequence of this somewhat laissez faire attitude and failure to

develop rigidly professional and more or less uniform curricula,

young entomologists graduating from different colleges manifest

a remarkable dissimilarity in philosophy of their science, in

magnitude and character of information and even in appreciation

of their responsibilities and opportunities.

The education of students of entomology is a matter of perti-

nent concern to teacher upon whom is imposed the responsibil-

ity of well equipping these young people for successful and com-

petent careers and of anticipating new demands upon entomolo-

gists as the scope of the profession expands and as new ap-

proaches and new interrelationships with other fields of science

develop as a consequence of the normal evolution of the profes-

[VOL. XXI, NO. 1

sion. Furthermore, responsibility for maintaining, and increas-

ing wherever possible, the standards and competency of profes-

sional entomology largely and inevitably rests upon the teachers.

Entomological education obviously is of paramount importance

to students who are preparing to enter the profession and who

rightfully expect their teachers and institutions to equip them

well for the career upon which they intend to embark. The

training of students of entomology is equally important to ento-

mologists who are engaged exclusively in research, regulatory

work and other entomological occupations distinct from teaching,

since they not only have a natural interest and pride in the pro-

fession of which they are members, but also have the responsi-

bility of hiring from time to time young entomologists of whom

they expect adequate qualifications. Finally, the general public

which financially supports entomology is justified in expecting,

and even demanding, thoroughly competent entomologists and

entomological service of the highest calibre. Thus we see that

the education of students of entomology is an extremely perti-

nent matter to both professional workers, actual and potential,

and to the general public. Particularly must the teachers and the

colleges consciously recognize the noblesse oblige that is ines-

capably theirs.

In order to properly appreciate and evaluate the problem

which confronts us, we may ask ourselves certain fundamental

questions.

The first basic question to answer is what is an entomologist?

This question can be answered simply by stating that he is a per-

son engaged in the study of the accumulated and accepted knowl-

edge of insects and certain other arthropods with reference to the

discovery of general truths or the operation of general laws and in

adding to this knowledge and making practical applications of it.

However, for the more thorough appreciation and evaluation of

the problem of professional training in entomology, it is better to

erect a more complete definition which recognizes that an ento-

mologist is first a biologist, second a zoologist and finally an

entomologist. This more basic concept emphasizes the true posi-

tion of the entomolgist as a scientist and more clearly indicates

the exact nature and magnitude of his specialized training. It

should be obvious that failure to accept such a point of view

will inevitably result in imposing upon the student restrictions

which will narrow the scope of his activities in contributions to

JANUARY, 1945] STEWART-PROFESSIONAL TRAINING

his field of science. The acceptance of this definition elucidates

the extent of specialized education concerned directly with ento-

mology, and without regard to the correlated subjects, demanded

for true professional status. Extending the definition to comple-

tion, one must accept the fact that entomology is so complex as

to necessitate subdivision into the specialized fields of system-

atics and the several aspects of applied entomology.

The second question that must be satisfactorily answered is,

what are the responsibilities of entomology as a profession? The

most readily apparent reply is that entomology is concerned with

the protection of man’s food and clothing, much of his financial

investment and his health and that of his domesticated animals

from the direct and indirect ravages of arthropods. It is also

responsible for the possible furtherance of the effectiveness of

insects beneficial to man and his interests. A moment’s reflection

presents the fact that entomologists engaged exclusively in what

is called, for the sake of convenience, applied entomology are

not able to completely discharge their responsibilities alone.

Systematists should be working in closest collaboration with such

entomologists and supplying them with basic information.

Since, by previous definition, entomology in part is also con-

cerned with the discovery of general truths and the operation of

general laws, responsibility rests upon the profession for train-

ing competent workers in taxonomy and encouraging adequate

museum facilities and for providing personnel for bionomic and

other systematic studies and investigations. These entomologists

together with the economic workers effect the compilation of

scientific entomological knowledge.

A third type of responsibility is met by providing profession-

ally trained entomologists for research and service in the insec-

ticide industry.

It is manifest that in each of these general aspects of ento-

mology, which jointly share the professional responsibilities,

there are numerous highly developed specialties. At a casual

glance it might appear that these specialties are rather distinct

and narrowly restricted. Such a concept is entirely erroneous.

It is highly urgent that each specialist be sufficiently thoroughly

trained in entomology and allied basic subjects and indoctrinated

with the broad scientific point of view to have a good working

knowledge and sound appreciation of the other fields of ento-

mological specialization. The degree of individual competency

THE PAN-PACIFIC ENTOMOLOGIST

[VOL. XXI, NO. 1

and ethical success of the profession is in direct proportion to

the completeness and rationality of the professional training

afforded to the student.

The preceding statements and analyses are admittedly not new

and are elementary, but it is necessary to review the concepts they

express and to keep them in mind constantly if the current re-

quirements for professional status in entomology are to be criti-

cally examined and if a rational approach is to be made to the

problem of future improvements in entomological education.

Before advancements can be made in the professional training

of entomologists, with consequent elevation of standards and

greater competency in discharging ethical professional obliga-

tions, the faults and deficiencies in prevailing entomological

curricula must be recognized.

Perhaps the most prominent fault in our curricula is failure

to recognize clearly the truly professional status of entomology

and to treat it accordingly. It is true that we speak of the pro-

fession of entomology, but not with a full and conscious realiza-

tion of the significance of the term and recognition of the respon-

sibilities membership in it incurs. We have not benefited by the

educational experiences of the older professions such as medi-

cine, law and chemistry. Failure to profit by the experience and

history of older and comparable fields of effort inevitably results

in some retardation of progress. Not one of the older professions

would accept new students to more or less full status late in their

undergraduate years, or omit a rather definite schedule of pre-

requisites, or permit widely dissimilar courses of study, or fail

to differentiate between pre-professional and professional courses.

Departments of instruction in entomology, however, are guilty

of all of these educational misdemeanors.

Another fault in entomological education is failure to view

the field as a whole and as a distinct discipline with necessary

ramifications and delimitations. This is a reflection of a weak-

ness in recognition and appreciation of the fundamental and

scholarly philosophy upon which the profession must be based.

Such definitions as are presented earlier in this paper must be

accepted and abided by to avoid this serious pitfall of omission.

Lack of clearly defined concepts and goals and logical approaches

to these goals inhibit, if not prohibit, the attainment of adequate

curricula and professional competency.

The absence of some reasonable degree of standardization of

JANUARY, 1045] STEWART— PROFESSIONAL TRAINING

•5

entomological curricula constitutes a serious obstacle in develop-

ing consistently entomologists of truly professional calibre. Any-

one who has ever been concerned with the teaching of entomol-

ogy at the graduate level has been strongly impressed by the

great divergencies in the character and magnitude of undergrad-

uate curricula in different universities. The obvious result of

such a lack of standardization of curricula is that the employer

of young entomologists must pay undue attention to the school

from which an applicant graduates, and even to the professors

under whom he studied, and cannot assume, making exceptions

for normal differences in native intelligence, industry and integ-

rity, that almost all young graduates in entomology are more or

less equally competent professionally.

It is deplorable that nearly every department of entomology

in the United States fails to differentiate in practice, if not in

regulations, between undergraduate or pre-professional and grad-

uate or professional courses. One finds a remarkable hodge-

podge of courses upon examination of the curriculum for a given

semester, or year, of almost any student in entomology. This is,

perhaps, particularly true of the graduate student, who frequently

is taking concurrently one or more undergraduate courses and

courses of the most advanced nature.

Because of an apparent inability to recognize that entomology

is a distinct discipline and must be treated accordingly, even

though it may transect or be intimately correlated with many

other fields, or even a group of fields as well exemplified by the

relationship between entomology and agriculture per se, there is

often indecision as to what subjects should be required in the

curriculum and even sometimes vitally essential courses are sac-

rificed because of a mistaken conviction that certain other courses

should be required. It must be recognized that the first respon-

sibility of the department of entomology and the first obligation

to the students is that of adequate training for competency in the

precise discipline of entomology as a profession and that other

courses are of secondary importance, except those which are

actually basic to entomology and those which should be reason-

ably expected as a part of the cultural education that should be

claimed by and demanded of every college graduate.

A laxity in the matter of prerequisites has already been sug-

gested in the comparison made between departments of ento-

mology and departments or schools training students in the older

THE PAN-PACIFIC ENTOMOLOGIST

[VOL. XXI, NO. 1

professions. The most serious neglect to prerequisites occurs not

so much in the courses in entomology as in the proper sequence

and correlation of basically important courses outside of those

restricted to entomological studies and upon which thorough

competency in entomology depends and also of prerequisites to

eligibility for admission to graduate school and adequacy for

instruction at the graduate level. It is almost the rule, rather

than the exception, to see graduate students in entomology pur-

suing studies which should have been completed during under-

graduate years. It is indeed tragic that such an easily solved

problem persists even in our better institutions.

Partly because of lack of accurate appreciation and under-

standing of the discipline of entomology as a science, partly be-

cause of lack of properly organized curricula, partly because of

lack of serious study of the needs of the student preparing for a

professional career in entomology and partly because of failure

on the part of teachers to anticipate probable future demands

upon entomology we find, perhaps more frequently than not, a

deplorable lack of breadth of training in our entomologists, not

only in the more narrowly restricted science of entomology itself

but more especially in the basic fields upon which entomology

is dependent. It is doubtful if there is a mature entomologist

who does not regret that his own training is so conspicuously

deficient in certain fundamental things in which he should have

been trained as a student. This does not refer necessarily to those

fields that have become important recently as a consequence of

evolution of the profession, but to those subjects which should

have constituted logically a part of his education at the time he

was a student. Breadth of training not only in entomology per

se, but also in related fields basic to or closely correlated with

such professional training are especially urgent for the potential

entomological investigator.

This is not the place nor the time to present anything that

pretends to be a complete or definite curriculum for students

who desire to qualify as professional entomologists. Obviously

such a curriculum can be erected only from intense and exhaus-

tive study and should be the product of a carefully selected

group of experienced teachers. However, it is clear that the dif-

ference between undergraduate and graduate instruction should

be clearly defined and understood. No thoughtful modern en-

tomologist would endorse the idea that undergraduate training

JANUARY, 1045] STEWART-PROFESSIONAL TRAINING

alone qualifies a student as a professional entomologist. The

master’s degree has long been, and still is, a perplexing problem

to the educator; but we are probably justified in assuming that

it satisfies some need in entomological training. It is an irre-

futable fact that modern professional demands are such that it

is extremely difficult and probably will soon become impossible

for the young man or woman to attain full professional status

in entomology without first achieving the degree of Doctor of

Philosophy or its equivalent. From these facts one may justifi-

ably accept some such concept as the following relative to ento-

mological education. The undergraduate curriculum may well

be considered a pre-professional course, i. e. a pre-entomological

course, in which the student is afforded the opportunity to ac-

quire adequate preparation for instruction at the graduate level

and, at the same time, the cultural education that should be de-

manded of every graduate of a reputable college or university.

As indicated above, the master’s degree is something of an

enigma but might be considered a legitimate and creditable at-

tainment for the student who intends to enter regulatory work

or to fill some commercial or industrial entomological niche at a

sub-professional level. The graduate training directed toward

earning the doctorate must be intensive work of a very high

scholastic character, fulfilling truly professional criteria. Such

a philosophy of instruction demands a carefully planned pro-

gressive and coordinated program with a clear understanding of

the distinction between the pre-professional character of the

undergraduate curriculum and the professional stature of the

graduate studies.

As previously indicated, no attempt is being made in the

present discussion to erect curricula for professional training in

entomology; but certain salient and fundamental points may well

be mentioned briefly. Manifestly, the student requires as much

and as thorough training in entomology as possible. However,

the usual tendency to compress the greater part, if not all of this,

into the undergraduate years should be avoided. Instead thereof,

these courses should be logically and progressively correlated

and arranged to extend throughout the four years of pre-

professional training and well into the graduate years of study,

leaving ample time for the undergraduate student to take ade-

quate course work in allied scientific subjects and necessary and

desirable cultural courses. Such a recommendation immediately

THE PAN-PACIFIC ENTOMOLOGIST

[VOL. XXI, NO. 1

raises the problem of the student who decides relatively late in

his undergraduate course to enter professionally the field of

entomology. There is only one rational and ethical answer to this

problem and that is to insist that such students fulfill completely

the established requirements regardless of the fact that they may

be penalized in many instances by the necessity of devoting one

or more additional years to the attainment of a bachelor’s degree.

Failure to adhere to such rigid requirements and definite pro-

gram can result only in the lowering of the professional stand-

ards. The older professions of medicine, law, and chemistry have

long ago recognized the necessity and wisdom of such an attitude.

During the undergraduate years the student should receive

thoroughly adequate training in zoology and botany and in

physics and chemistry. However, if studies of the development

of the entomological curriculum so indicate, the more advanced

required courses in chemistry might be extended into the grad-

uate training. Genetics, plant pathology and plant physiology

should be required of the pre-professional student. One of the

greatest crimes being committed in entomological education to-

day is permitting the very frequent occurrence of postponement

of studying French and German until the student has matricu-

lated in the graduate school. The usual result of this is that

the student learns barely enough of these languages to satisfy a

lenient examiner and never is able to read French and German

accurately and easily. Certainly every student who intends to

become a professional entomologist should be required to be-

come competent in reading these languages before begininng

graduate studies. The entomological investigator has urgent need

of at least a working knowledge of statistical analysis. Conse-

quently mathematics through statistical analysis should be re-

quired; if necessary to prevent the overcrowding of the under-

graduate curriculum, the advanced work may be covered during

graduate instruction. Elementary economics, at least, might well

be required of the student in entomology and competency in

English should be demonstrated before admission to graduate

standing. Most educators recognize and deplore the astounding

ignorance of the fundamentals of the English language mani-

fested by a considerable proportion of graduate students in ento-

mology. Undeniably the professional entomologist who is unable

to speak and write well and accurately is severely handicapped.

In addition to the subjects previously mentioned, the undergrad-

JANUARY, 1045] STEWART-PROFESSIONAL' TRATNTNG

uate student should have as broad a training as at all feasible in

the social sceinces and the humanities and thereby enjoy the dig-

nity and prestige of the educated man, an inescapable responsibil-

ity of every reputable college and university regardless of the

specialized curriculum of the individual student. To insure the

discharge of this responsibility and the consequent dignity of the

entomological profession, the departments of entomology might

very well arrange these cultural subjects into logical groups and

require each student to satisfy certain minimum requirements in

each group. Admittedly such a schedule would curtail the stu-

dents’ usual freedom of choice in the matter of electives, but is

such a restriction undesirable? It can be strongly argued that

closer direction of the undergraduate’s selection of elective sub-

jects is highly desirable because of his own necessarily limited

ability to evaluate courses and to appreciate problems of subject

correlations and the necessity of broad professional and cultural

perspectives. Furthermore, closer regulation of electives will re-

sult in the student profiting more from the considered judgment

of the mature scholar.

Some will wonder, and even challenge, why courses in agri-

culture per se are omitted from the general consideration of an

entomological curriculum as presented above. The most impor-

tant reason for this omission is that an entirely adequate pro-

gram for the training of students in entomology up to the truly

professional level does not permit, in the space of seven or eight

years of college study, the inclusion of much in the way of strictly

agricultural subjects without sacrificing other courses of urgent

and greater importance to entomology as a distinct profession.

Another reason for this point of view is that agricultural prac-

tices are constantly developing and changing and what the stu-

dent learns in college of these things is frequently out-dated

within a period of very few years; such a condition does not

justify overcrowding or infringing upon an already heavily bur-

dened and exacting curriculum. Finally, the actual need of

courses in agriculture is questionable since experience has shown

that the fundamentals and the practical details necessary to the

entomologist in his investigations in agricultural entomology and

his recommendations for insect control are easily and quickly

acquired in the course of early professional duties through con-

ferences with and advice of cooperating agricultural specialists.

Thus far no mention has been made of the graduate student’s

[VOL. XXI, NO. 1

research and dissertation. It is sufficient here to point out that

the fundamental purpose of this aspect of graduate requirements

is to acquaint the student, on a broad plane, with research meth-

ods and to afford him an opportunity to demonstrate his ability

to organize and conduct research and to properly and adequately

handle the results obtained from such investigations. If the

teacher recognizes the implications contained in such a concept

of the dissertation, he will immediately appreciate the serious

thought that must be given to the selection of a research problem

for the graduate student and the careful and discreet guidance

that he must give to the student. Too frequently, the research

problem is either carelessly or thoughtlessly chosen or is selected

to further the professor’s own research, either of which should

disqualify the professor for the privilege and responsibility of

directing graduate students.

The problems presented in this discussion are urgent and of

major importance if the scholarly and scientific heritage of the

field of entomology is to be preserved and is to serve as a source

of inspiration to future entomologists as it has been to those of

the recent past and if entomology is to deserve the dignity of a

professional status.

TWO COLEOPTERA RECENTLY ESTABLISHED IN

SOUTHERN CALIFORNIA

C onoderus laurentii (Guer.) This West Indian elater was ac-

cidentally introduced into Florida and Alabama at least forty

years ago and is now well established there. On August 2, 1938,

I received a specimen of the same from E. Herald, taken on his

lawn in Los Angeles and on October 15, 1944, another specimen

collected by Mrs. Barbara Prendergast, at Hollywood. Accord-

ing to Prof. Ralph H. Smith, this species is now fairly well es-

tablished in lawns in various places in southern California.

Staphylinus ( Goerius ) olens Mull. A common European spe-

cies, generally listed as Ocypus olens Mull, in most insect works,

was first noticed at Hollywood, April 16, 1936, and West Los

Angeles in November, 1940, and more recently found in abund-

ance in various places near the Campus of the University of

California at Westwood, Los Angeles, according to Prof. R. H.

Smith. These are, I believe, the first records for this species in

this country. Fortunately it is a beneficial insect. — Edwin C.

California, where the caterpillars fed on the leaves and green

pods and seeds of beans, especially the pole types. In certain

instances the damage was so severe that almost complete defoli-

ation of the plants resulted. During July, 1936, a previous out-

break of this insect was noted at Half Moon Bay, California, at

which time the caterpillars damaged a white Kentucky Wonder

pole bean. At Salinas the larvae pupated during November,

rolling the leaves and transforming within a silken cocoon.

Adults emerged in December, 1943, and again in May, 1944.

Several generations occur during a single year. Four parasites

of the larvae were found. A count made of caterpillars collected

during August, 1943, indicated the relative per cent of parasit-

ism as follows: Copidosoma probably truncatellum (Dalm.)

(det. A. B. Gahan), 14 per cent; “Amblyteles” montarms (Cr.)

(det. H. K. Townes), 1 per cent; “Ephialtes” sanguineipes (Cr.)

(det. H. K. Townes), 1 per cent; and Chaetogaedia monticola

(Big.) (det. M. T. James), 3 per cent. In addition to these para-

sites a fungus killed 2 per cent of the larvae and 2 per cent

failed to emerge for unknown reasons. The adult moth was

kindly determined by Carl Heinrich. — W. Harry Lange, Jr.

NOTES ON THE GENUS THAUMAINA

(Lepidoptera: Lycaenidae)

BY R. G. WIND 1 AND H. K. CLENCH 2

t . 1 |

The monotypic genus Thaumaina was erected in 1908 by

G. T. Bethune -Baker for the new species described under the

name uranothauma. It is a very distinct genus, bearing a pat-

tern relationship to the genus Uranothauma Butler (P. Z. S. 1895,

p. 631), hence the specific name. It remains one of the peculiar

developments of the vast island of New Guinea.

Genus Thaumaina Bethune-Baker

Bethune-Baker, 1908, P. Z. S. 1908, p. 116. Genotype. Thaumaina

uranothauma B.-B.

The single species thus far known appears to be restricted to

eastern New Guinea, where it is broken up into two races, one

of which is described herein as new. It is evidently a highland

butterfly, and does not appear to be very common.

The typical form was described ( loc . cit. and pi. 9, figs. 8, 9)

from the Angabunga River, a tributary of the St. Joseph River,

which empties on the south coast of eastern New Guinea. On the

opposite side of the Owen Stanley Mountains occurs a race of

this species. Karl Jordan (1930, Proc. Ent. Soc. London, 5:60,

pi. 3, f. 10) has figured a female of this subspecies that agrees

well with the allotype described below. This specimen originated

on the Edie River, west side of Herzog Mountains, eastern New

Guinea. Two males were taken with it, but were not figured.

Thaumaina uranothauma deliciosa Wind and Clench,

new subspecies

Upper side:

Male. Fore wing blackish brown with a bright purplish blue

patch in the base, from inner margin up to include the lower half

of the cell, and extending two-thirds outwards on inner margin.

Hind wing with the outer half (nearly two-thirds the area) of the

wing brownish black. Costa inside white, darker outwardly. Re-

maining portion of the wing (save for a narrow inner marginal

border) purplish blue. Fringe of both wings black and white

checked.

Female. Fore wing similar to that of the male, but with the

blue changed to white and a little more extensive, and with a dark

bar extending down over the cell-end from the costa. Hind wing

with a broad (outer third of the wing) black-brown border. The

remaining area is white with pale blue scaling over the inner

marginal part. Extreme base black-brown. Veins in the white

area lightly scaled with black-brown. Fringe as in the male.

Underside :

Male. Fore wing with the ground color white. A dark ban scal-

loped marginal border, behind which is a row of alternately dis-

located hollow quadrate spots. This row extends from costa to

Cu 2 , while the marginal border proceeds all the way to the inner

margin. In the M 3 -Cui and Cui-Cu 2 interspaces the border and row

of spots touch. On the costa is a triangular, black-brown spot,

its apex narrowly produced to cover the cell-end. In the base is a

long bar, parallel to the costa, and with a connection to it at its

outer extremity. Hind wing with the dark tan scalloped border

as in the fore wing, but with the Cui-Cu 2 lunule enclosing a black

spot. In the Mi-Cm interspace is a series of connected, jet-black

spots, touching the marginal border. In the interspaces from Cu a

to the inner margin are three more heavy spots, decreasing to-

wards the latter in depth. Base of wing with an irregular black

spot. A black, heavy dash, faintly white within, closes the cell.

On the costa, almost on the outer angle, is a hollow, nearly circu-

lar spot, and one-third from the base is a couplet of similar, though

smaller, spots. These markings are all crowded, and almost all

appear quite confluent.

Female. Similar to the male, save that the post-discal row of

spots on the fore wing is larger and more confluent, and as a

consequence, less dislocated.

Length of fore wing : Male and female, 11.5 mm.

Holotype male, Wau, Morobe District, New Guinea, Janu-

ary 30, 1933 (H. Stevens). Allotype, female, Mt. Misin, 6400

feet, Morobe District, New Guinea, May 2, 1932 (H. Stevens) .

Paratypes, two males, same locality and date.

Holotype and allotype in the Museum of Comparative Zoology.

One paratype in collection of each author.

Remarks. This subspecies appears to differ in a number of

respects from the description and figure of Bethune -Baker. The

black border of the male appears a little heavier on the fore

wing, and even more so on the hind wing. On the latter there is

no indication of the white spot mentioned and illustrated by

him. In the female there are no white spots in the dark border

of the fore wing (two were described, and both show up well in

the figure), and the cell is closed by a dark streak running from

the costa, absent in the description and figure of the typical sub-

species. In the hind wing the pale blue scaling of deliciosa is

not mentioned by Bethune-Baker, or depicted in his figure. The

underside appears to be similar, but perhaps with the spots

slightly larger.

ON THREE SPECIES OF AGABUS RECORDED FROM THE

STATE OF MONTANA 1

(Coleoptera, Dytiscidae)

BY HUGH B. LEECH

Vernon, British Columbia

The inclusion of Agabus confertus Le Conte (det. H. C. Fall)

in Mank’s list of the Coleoptera of Glacier Park (1934, p. 75)

was for some years a puzzle to me, as all specimens I had seen

were from much nearer the coast. Through the kindness of Miss

Mank I examined both Montana specimens on May 3, 1939, and

found them to be Agabus erichsonii G. & H., a species of similar

facies. A. confertus may yet be found in Montana for I have

seen one taken at Boise, Idaho, June 15, 1941, by Borys Malkin.

In September 1941, Dr. Harlow B. Mills was so kind as to

allow me to examine certain of the Agabus reported upon by

Hatch (1933, p. 10). The A. seriatus (Say) of Hatch are all the

subspecies inter sectus (Crotch) of Leech 1942. The series of

“obliteratus Lee.” proved to be composite; two of the specimens

from Bozeman are strigulosus (Crotch) ; the others, as well as

those from Shields River and Bitter Root Valley are A . nectris

Leech.

A NEW JAVANESE OROCHLESIS AND A CHECKLIST OF

THE GENUS

(Coleoptera, Curculionidae)

BY ELWOOD C. ZIMMERMAN

Bernice P. Bishop Museum, Honolulu

Among some specimens of insects collected in Java by Mrs.

M. E. Walsh, there is a pair of weevils which represent a distinct

new species of the cryptorhynchine genus Orochlesis Pascoe,

1871. There have been no Orochlesis reported from Java here-

tofore, and this paper is written principally to record the addi-

tional geographical data supplied by the new species.

With the description of another new species, the number of

known Orochlesis is raised to 24. A new checklist of the de-

scribed species of the genus, arranged by locality from east to

west, follows:

This species is not closely allied to any of the other species

of the genus known to me. The large black prothoracic macula

is broken down in the male holotype, but it is very conspicuous

in the female allotype on which it somewhat resembles a broad

black tear-drop. It is almost circular in form, but the anterior

part is extended forward to make a tear-drop or inverted sub-

heart-shaped macula. The setae on the alternate elytral intervals

appear as rows of small black dots to the unaided eyes. The

scales are unusually large and dense overall.

Sciences, San Francisco

The species under consideration, inhabit the arid areas of the

Sonoran Region of the south-western United States, northern

Mexico and Lower California. They are as follows:

A Mexican species described from a unique specimen, resem-

bling the common Sonoran species ( verrucosa Lee.) in form and

tuberculate elytra, except that the fifth interval of each elytron

is convex, more or less prominent and costate from the elytral

base to about posterior third of the length (fig. 13), and there

changing to tubercles. In the type and only known specimen, the

distal segments of both antennae are missing, the character of

the eleventh or terminal segment being unknown. This fact

leaves the correctness of the determination open to doubt.

24 THE PAN-PACIFIC ENTOMOLOGIST [ VOL. XXI, NO, 1

In Cryptoglossa the eleventh antennal segment is short, trans-

verse and more or less sunken into the tenth segment.

The author considers it absolutely necessary to present facts

and to leave the final decision to future students, when other

specimens shall have been collected.

A common and moderately large, black, opaque and more or less

pruinose species. Pronotum narrower posteriorly than at apex,

the latter arcuate and sinuate within the rather large and dis-

tinct angles; sides arcuate anteriorly, moderately convergent pos-

teriorly before the basal angles, the latter distinct, scarcely promi-

nent; base truncate to feebly emarginate. Disk extremely and

densely, finely granulate, strongly convex, especially anteriorly;

impressions well marked, more or less finely canaliculate on the

median line, sublateral strong; base transversely impressed.

Scutellum short, triangular and not entering between the elytra.

Elytral base applied to the pronotal base; sides arcuate, surface

declivous apically, apex subacute. Each elytron has nine series of

rather large subarcuate tubercles, the latter obsolete before the

apex; surface viewed vertically the tubercles appear irregular and

not serial, viewed obliquely and longitudinally from behind they

appear in distinct series; more or less variable in size, showing a

tendency to become slightly longer than wide at base, toward

elytral base they may become smaller, laterally they become rather

subacute and the inner or discal appear obliquely elongate to

almost subcarinate and most prominent at their apex. The first

or sutural interval plane, slightly irregular on surface with scat-

tered very small points.

Measurements: Length 19-20 mm., width 8-10 mm.

Males: Usually smaller and narrower, abdomen moderately

convex.

Females: Larger, wider and rather more robust, abdomen more

convex.

Three living specimens were received by the author, April 21,

1933, from a collector in Arizona, two females and a smaller

male. The author decided to keep them under observation and

on a very restricted diet, rolled oats without water. A glass jar

was prepared, by partly filling with sand, covered by a layer

of oats.

The smaller female died about the sixth year, without any

special record. The male died July, 1939, after having lived in

the jar for six and one-half years. For diversion and exercise

the specimens spent part of their time, clawing and digging

into the oats and sand, evidently trying to develop a burrow.

The larger female began to show signs of senility at about the

sixth year of its confinement; this was noticeable in its dimin-

ished activity, with loss of tarsal segments and the two or three

terminal segments of the antennae. For the last weeks it scarcely

showed signs of life, and died July 10, 1940. During the last

weeks a drop of water was placed before it on the table. It

would approach the water and sip it up entirely, without any

bad effects. The two specimens are preserved in the collection

of the Entomological Laboratory of the California Academy of

Sciences.

Cryptoglossa verrucosa carinulatus Blaisdell, new subspecies

Form as in verrucosa LeConte. Frons convex, very sparsely

punctate, punctures small in central area, becoming larger and

denser apically and laterally. Sides of head broadly and rather

feebly emarginate across the position of the oblique sutures, the

latter feebly evident or obsolete; epistoma truncate at apex. Men-

tum broadly emarginate at apex and somewhat widely margined,

surface moderately convex, not sharply nor densely punctate, im-

punctate at base; gula transversely rugose.

Pronotal disk very densely and finely granulate, a feebly and

slightly impressed median line is present, other impressions quite

feeble, except a distinct basal sulcus which does not attain the

sides. Prothoracic sides slightly irregular, impunctate or very

feebly subpunctate, especially anteriorly. Prosternal process

broadly margined at apex, surface impunctate or irregularly

punctate with intervals rather wide.

Elytral intervals in the central area carinulate, each carinula

not strong, each divided into carinules by fine transverse fissures,

each represents a modified tubercle, which can be seen in speci-

mens of verrucosa as subcarinal tubercles; these at the begin-

ning of the lateral declivity gradually develop into verrucae, which

at first are oblique and angulate posteriorly to form the usual

obtuse prominences; sutural intervals plane, finely and sparsely

granulate; striae of punctures not distinct; tubercles not sharply

defined and broader at base, irregularly involving the intervals.

Sternal and parasternal punctures large, well separated and

not sharply defined. Abdominal punctures moderate in size; and

sparseness, larger and denser laterally especially on first segment;

fifth segment with denser and smaller punctures.

Male. Usually smaller and narrower, elytra less arcuate at

the sides.

Female : Broader and subovate, ielytra more arcuate at the

sides.

NOTES ON REDWOOD CERAMBYCIDS (COLEOPTERA)

BY J. W. TILDEN

Santa Cruz, California

In the winter of 1932-33 I reared a few specimens of ceram-

bycids from Coast Redwood at Santa Cruz, California. Dr. E. C.

Van Dyke kindly determined them as his species, Semanotus

ligneus sequoiae Van Dyke and Callidium pallidum Van Dyke.

There was also one specimen of Opsimus quadrilineatus Mann.,

a species normally associated with Pseudotsuga taxi folia (Lamb.)

Dr. Van Dyke urged me to secure more of these insects, and

suggested further rearing.

Redwood second growth that had been attacked in the forest

by Cerambycidae was stored in wooden boxes indoors in the

winter of 1933-34, but with poor results, as only a few specimens

were obtained. It was found that mortality at emergence was very

high. This may have been due to greater dryness since these in-

sects are normally exposed to very damp weather.

In March, 1935, a second growth redwood about ten inches in

diameter was cut down in the woods. It remained exposed to

attack all summer, and in the fall was found to be heavily in-

fested with beetle larvae.

In March, 1936, an examination of the tree showed that the

beetles had transformed from pupae to adults and were ready to

emerge. To prevent normal emergence and loss, they were re-

moved from the tree, so that the normal date of emergence was

not obtained. Collection dates of free specimens taken in the

same locality range from late February to the middle of April

in these same species.

The number of adults removed from this one tree was large:

upwards of 70 specimens of Semanotus ligneus sequoiae, about

150 of Callidium pallidum, and in the upper small branches, a

number of specimens of Phymatodes nitidus Lee. In addition to

these, a few specimens of Callidium sempervirens Linsley were

taken from the twigs at the tip of the tree.

Larvae of T emnocihila virescens (Fab.) and a single raphidid

larva were found in the burrows of Semanotus, while an unidenti-

fied fungus killed some pupae; but on the whole these beetles

seemed remarkably free from both parasites and predators.

JANUARY, 19451

CAMRAS— ZODION

From the available data, the following conclusions are drawn:

1) These cerambycids attack the Coast Redwood and develop

in freshly cut or injured wood (especially in second-growth

timber or in limbs?). The larvae first feed in the drying

cambium and later in the sapwood, but eventually may

bore deeply into the wood. They usually return nearly to

the surface, just below the bark, to pupate. The species

observed develop from egg to adult in one year.

2) They show specific preference for certain parts of the tree.

Semanotus is found in the main trunk of second-growth

trees, Callidium pallidum Van Dyke occurs in the branch-

bearing part of the trunk and in the larger branches, while

sempervirens and Phymatodes nitidus prefer the smaller

branches and trees.

3) These species are less rare than previously supposed, and

proved able to build up large populations under optimum

conditions such as those afforded by the presence of a

freshly cut tree at the time of oviposition.

4) Opsimus quadrilineatus Mann., previously associated only

with Pseudotsuga taxi folia (Lamb.) seems able to utilize

Sequoia sempervirens (Lamb.) as a food supply.

FURTHER NOTES ON SOME SPECIES OF ZODION

(Diptera, Conopidae)

Since the publication of notes on the Zodion fulvifrons group,

the author has visited the museums in the East and has examined

many types. As a result, the following changes must be made:

Zodion reclusum Banks. The type has some reddish on the

sides of the second abdominal segment not mentioned in the

original description. There is also much yellowish on the other

segments and therefore belongs under fulvifrons rather than as

a synonym of intermedium.

Sicus brevirostris Coquillett (1902, Canad. Ent. 34:198 —

Mexico: Chihuahua: Sierra Madre). This species is a Zodion,

the second segment of the proboscis noted by the describer be-

ing the labellae. The palpi are clubbed, two to two and one-

half times the width of the proboscis; and the species does not

seem to differ from palpale.

Zodion bimacula Curran. The type is an individual in which

the distal portion of the proboscis is broken off. It is a speci-

NOTES ON SOME MOTHS OF THE FAMILY SATURNIIDAE

(Lepidoptera)

BY J. W. TILDEN

Santa Cruz, California

While collecting in the Pozo Mountains in the general region

of La Panza, San Luis Obispo County, on March 23, 1940, George

Mansfield and the author took three male specimens of a Calo-

saturnia sp.

This area is a typical chaparral association of Ceanothus, Arc-

tostaphylos, Cercocarpus, Adenostoma, Photinia, Dendromecon,

with Quercus spp. in the canyons. The specimens were taken

flying in typical undulating fashion over the chaparral on the

west side of the divide.

I have been informed by Mr. J. W. Johnson (personal com-

munication) that there exist to his knowledge no previous records

of this genus from San Luis Obispo County. Inasmuch as this

area is outside of the habitats of his two recently described spe-

cies of Calosaturnia, C. albofasciatus Johnson and C. meridion-

alis Johnson, it appears probable that the specimens from the

Pozo Mountains are referable to Calosaturnia mendocino (Beh-

rens), the type species of the genus, thus extending the already

wide known range of the species.

In July, 1941, six larvae of C. mendocino were taken in the

Santa Cruz Mountains. All were of the pink or orange color

phase, none being of the dark or green phase. Of these, three

pupated in typical satumiid cocoons in a few days. Two others

succumbed to A panteles parasites, and a sixth disintegrated, pos-

sibly from a bacterial disease. Of the three pupae, one emerged

in an injured condition on January 17, 1942. About the same

time, a second pupa produced a tachinid. The third pupa did

not develop either adult or parasite. The food plant of the larvae

taken was Arbutus menziesii Pursh. Several of our party com-

plained of the stinging setae of these larvae, and I personally

discovered that the setae are indeed quite painful, however, the

effect does not last long.

In late July, 1941, a few days after the mendocino larvae were

taken, over 50 larvae of P seudohazis eglanterina were obtained

from Ceanothus thyrsiflorus Esch. These larvae were almost ma-

ture when taken, and after feeding for from one to eight days,

either succumbed to parasites or attempted to pupate. Thirty-

one died from Apanteles parasites. Others formed cells even

when covered with Apanteles cocoons, but failed to pupate. Only

six pupae formed from the total number, and of these six, five

emerged tachinids during the winter. Only a single adult was

obtained from more than fifty larvae. I do not believe this to be

an extreme case of parasitism. An almost similar result was ob-

tained from larvae of Papilio philenor hirsuta Skin., in 1938,

from Putah Canyon, Yolo County, California. Where larvae are

taken nearly full grown, parasitism is far more marked than in

larvae taken in the early instars.

While collecting in the White Mountains of California, near

Benton Station, Mono County, C. W. Bowles and the author took

a large number of satumiid larvae on Salix sp., along a small

watercourse. In view of the location and the food plant, these

are circumstantially considered to be the larvae of Platysamia

gloveri Stkr. Attempts to rear these larvae resulted in complete

failure, all specimens falling victims to Apanteles previous to

pupation.

I have been informed by Mr. J. W. Johnson that this is the

first record of larvae of this species from a California locality,

although the adults have been taken within the state on several

occasions. Mr. Johnson agreed that the larvae were most likely

to be gloveri, and suggested the inclusion of their occurrence, in

these notes. It seems logical that gloveri should include in its

range that part of California which falls within the Great Basin

region.

Proceedings

One Hundred and Eighty-first Meeting

The one hundred and eighty-first meeting of the Pacific Coast

Entomological Society was held at 2:30 p.m. on March 25, 1944, in

the entomological laboratories of the California Academy of Sci-

ences, San Francisco. President Stewart in the chair. The follow-

ing members were present: M. A. Stewart, E. G. Linsley, F. M.

Prince, E. C. Van Dyke, D. N. Murphy, A. E. Michelbacher, C. D.

Duncan, W. C. Reeves, P. Moorhead, F. N. Driver, R. F. Smith,

R. W. L. Potts, J. L. Gressitt, E. R. Leach, R. C. Miller. Visitors

were present as follows: Mr. Pedro Galindo, Mr. M. W. Allen, Mr.

M. Reed, Miss B. Patterson, Miss B. J. Franseen, Mr. G. L. Brown,

Mr. T. Hutchins, Mr. A. Branngan, Mr. J. E. Ryus, Mr. W. J.

Chamberlain, Mr. M. Marquis, Mr. M. Garcia, Mr. J. McCarty,

and Mr. R. Schuster.

The minutes of the previous meeting were read and approved.

The Membership Committee proposed the following names for

membership : Mr. Paul R. Jones, Mr. A. L. Deaver, Mr. Pedro

Galindo, and Mr. M. W. Allen. The motion was made and passed

that the Secretary cast a unanimous ballot for their election.

President Stewart raised the question of the desirability of

holding an annual field trip in 1944. After some discussion, Mr.

R. F. Smith moved that in view of transportation difficulties no

attempt be made to hold a field trip this year. The motion was

seconded and passed. Dr. Van Dyke moved that a meeting be held

at the Academy in the latter part of June in place of the annual

field trip. The motion was seconded and passed.

Dr. Duncan, Dr. Van Dyke, and others reported the where-

abouts and present assignments of various Society members now

serving in the armed forces.

Mr. R. F. Smith reported that he was anxious to learn the effect

of the current abnormally dry season upon the populations of

Colias eurytheme. He requested members to be on the look-out for

information on the subject whenever the opportunity arose.

Dr. Duncan recorded finding unusually long Gordian hair worms

in Jerusalem crickets in San Jose, one thirteen inches long, an-

other twenty-eight inches long. He mentioned that the worms had

emerged in a dry environment in the absence of water. Mr. Allen

JANUARY, 104.5] PACIFIC COAST ENT. SOCIETY

commented that specimens 36 and 42 inches long" had been re-

corded from the Mormon cricket.

President Stewart then presented Mr. J. Linsley Gressitt, a

Society member recently repatriated from occupied China, who

addressed the Society upon “Entomological Experiences in China.”

Mr. Gressitt stated that the experiences of an entomologist sta-

tioned in China are apt to be very different from those of one in

this country. For entomology is practically undeveloped in China,

as compared with the United States. Entomology has been largely

fostered in China by Americans and French, particularly as far as

education in entomology within China is concerned. The Japanese

have also played a part. Much of the early insect collecting in

China was done by French, British, Russians and Germans. Edu-

cational institutions playing the main role in China in recent years

include the American Christian Colleges in China, among them

Lingnan University of Canton where the speaker was stationed

for four years or so, the French Catholic universities in Teint-

sin and Shanghai, and several of the Chinese national universities,

such as Sun Yat-sen, Kwangsi, Szechuan, Central, and others.

Research institutions in China dealing with entomology include

the Academia Sinica and the National Agriculture Research Insti-

tute, both to some extent subsidized by American money, and the

Shanghai Science Institute, a Japanese institution. Other organ-

izations such as the Science Society of China have fostered re-

search and publication.

Among entomologists prominent in China Mr. Gressitt men-

tioned Sicien Chen and his wife Yon-yon Zia of the Academia

Sinica, C. F. Wu of Yenching University, F. C. Wu and Gaines

Liu of the National Agriculture Research Institute, C. L. Liu of

Tsing-hua University, C. Y. Liu of Kwangsi University, Prof.

W. E. Hoffmann of Lingnan University, Prof. C. R. Kellogg of

Fukien Christian University, Prof. B. A. Slocum of the University

of Nanking, Prof. A. W. March of Hangchow Christian College

and Fathers 0. Piel and B. Becquart of Universite l’Aurore in

Shanghai. Several American entomologists have in the past spent

one or more years teaching or helping to organize entomology in

China. These include J. G. Needham, C. W. Woodworth, E. C. Van

Dyke, W. A. Riley and C. W 1 . Howard. The latter two were at

Lingnan University, where also Dr. R. C. Miller, director of the

California Academy of Sciences, was in charge of zoology for a

time.

Prominent works on Chinese insects or entomology referred to

by Mr. Gressitt included G. F. Wu’s “Catalog of Chinese Insects”

and works on aquatic insects, Needham’s “Dragonflies of China,”

Hoffmann’s “Catalog of Scutelleroidea . . . ,” Ouchi’s “Bibliography

of Chinese Insects,” Yang’s work on Heteroptera, work on Orthop-

tera by Chang and Tinkham, on Homoptera by Metcalf, Funk-

hauser and Gaines Liu, on Siphonaptera by C. Y. Liu, Vespidae

by C. L. Liu and Coleoptera by Sicien Chen and the speaker. Some

THE PAN-PACIFIC ENTOMOLOGIST

[VOL. XXI, NO. 1

groups, such as Diptera, Hymonoptera, Lepidoptera and others,

have hardly been studied except for scattered descriptions of

species published in Europe.

Economic entomology is even less developed than systematic

entomology in China. This is partly for economic reasons since

the low living standards of Chinese farmers prevents their utiliz-

ing chemical control of insect pests on their own account, and

also may be partly due to the difficulty of changing long-estab-

lished agricultural practices. The lag is also in part attributable

to lack of government funds for agricultural research and a

scarcity of well-trained entomologists. With the help of the insti-

tutions mentioned above, and the impetus of the war, rapid prog-

ress is being made in certain lines, in spite of the difficult condi-

tions that prevail at present.

At present about the only general types of control that can be

recommended are cultural and mechanical methods, since chemicals

are practically unavailable, even if the farmers had the means to

buy them. Before agricultural entomology can be brought to com-

pare in any degree with that in the United States, the living

standards of the farmers, who form a large part of the population

of China, must be improved or the government must furnish mate-

rials and machinery for cooperative use. Biological control offers

an undeveloped field in China, but may not play as great a part

as it does in this country since many of China’s serious pests are

native, and a lesser proportion introduced from foreign countries

than is the case here.

Among prominent pests the speaker encountered in South China

were the Laichee Stink-bug, rice borers, rice beetles (criocerids

and hispids), roundheaded borers, scales, bugs, and leaf -hoppers

on Citrus, lantern flies and other fulgorids on various fruit trees

or shrubs, mulberry and fig borers (cerambycids) , flea-beetles and

galerucids on vegetables, Citrus and other plants, the banana weevil

and banana leaf -roller (a large hesperiid), the Laichee and Lung-

ngan (Longan) cerambycid borer, wax-moth, cabbage butterfly

and grain weevils and moths.

Mr. Gressitt reported that his work at Lingnan University

largely concerned the care of the collections in the Lingnan Natu-

ral History Museum and the development of the insectary of the

Natural History Survey where the life-histories of many of the

local insect pests were being studied. Complete preserved mate-

rial of the immature stages of these pests or local insects was

being assembled, as well as data. The speaker also had the oppor-

tunity of making three trips into Free China, two in northern

Kwantung and the other through Indo-China into Yunnan, Kwei-

chow and Szechuan provinces in West China, as well as collecting

in Hong Kong from time to time. Because of the Japanese occu-

pation of Canton, Lingnan University was divided in several

places: Canton, Hong Kong and later Free China. Thus the edu-

ably hampered. In addition to work for Lingnan University, the

speaker spent a few months collecting parasites of the red scale

in Hong Kong and Canton for shipment by clipper to California,

for the Citrus Experiment Station of the University of California.

After the United States entered the war Prof. Hoffmann and the

speaker were allowed to continue research on the Lingnan campus

for about a year and were even able to publish several papers,

called Special Publications of the Lingnan Natural History Survey

and Museum. Following this period came internment and then

repatriation to this country via the “Gripsholm” in December, 1943.

Mr. Gressitt’s talk was accompanied by movies and slides taken

at Canton, Hong Kong and in Free China.

Following a discussion of Mr. Gressitt’s paper the meeting ad-

journed. — E. G. Linsley, Secretary.

One Hundred and Eighty-second Meeting

The one hundred and eighty-second meeting of the Pacific

Coast Entomological Society was held at 2 p.m. on June 24, 1944,

in the entomological laboratories of the California Academy of

Sciences, San Francisco. President Stewart in the chair. The

following members were present: M. A. Stewart, E. G. Linsley,

R. C. Miller, J. L. Gressitt, R. F. Smith, E. C. Van Dyke and E. 0.

Essig. Visitors were present as follows: Prof. Herman A. Scullen,

Mr. Joseph E. Ryus, and Mr. William Russell.

The minutes of the previous meeting were read and accepted.

The Membership Committee proposed the following names, Dr.

Heber C. Donohoe, Mr. D. A. Zanette, and Mr. Charles Parsell, Jr.

They were duly elected to membership.

Dr. Van Dyke exhibited a new species of dobson fly, Neohermes

nigrinus Van Dyke, calling attention to the fact that much work

in neuropteroids remains to be done in the west. He also exhibited

two boxes of Coleoptera sent by Dr. Ross from New Guinea. He

noted especially a species of Pachyrhynchus, a group formerly

thought to be restricted to the Philippine fauna.

Dr. Van Dyke reported the capture in the spring of 1944 of a

mating pair of Bombus vosnesenskii. The female was freshly

emerged. The male appeared worn. He stated that it was gener-

ally believed that bumblebees mated in the autumn only, but this

observation suggested that there were two broods. Dr. Linsley re-

marked that in 1942 he had captured large numbers of males of

B. edwardsii and a few of B. vosneseskii and B. sitkensis in early

spring in Madera and Mariposa counties and in the previous year

had taken a few males of edwardsii in Shasta County. He sug-

gested that the production of vernal males might be characteristic

of certain western bumblebees and expressed the opinion that it

did not necessarily imply two broods.

President Stewart then presented Dr. R. C. Miller who ad-

dressed the Society on the subject “What is a species?” Dr. Miller

stated that as soon as the Linnean concept of a species as a sep-

THE PAN-PACIFIC ENTOMOLOGIST

[VOL. XXI, NO. 1

arate, permanent, and more or less easily recognizable, entity

began to prove untenable, the whole problem of what constitutes

a species fell into a state of confusion from which it has not

emerged. Thus one finds views of working taxonomists ranging

all the way from those who believe that positive (e„g. genetic)

criteria can be found for segregating species to those who frankly

consider species to be arbitrary groupings of individuals for the

convenience of biologists in arranging or discussing them. As a

matter of fact, even taxonomists who adhere to the former of

these ideas in theory, often follow the latter in practise. Accord-

ingly, as a working definition Dr. Miller proposed consideration of

the following:

“A species is a group of closely similar organisms segregated

on the basis of characters that can be recognized by the average

trained biologist.”

Many will object that “specialist” should be substituted for

“average trained biologist.” But if we grant this, we drift dan-

gerously toward taxonomic authoritarianism, under which a spe-

cies becomes whatever Dr. X or Professor Y says is a species.

The lack of agreement as to what constitutes a species empha-

sizes the importance of the type, and of promptly depositing type

material in a recognized museum where it will be permanently

available for study by present and future investigators.

After a discussion of Dr. Miller’s paper the meeting adjourned.

— E. G. Linsley, Secretary.

One Hundred and Eighty-third Meeting

The one hundred and eighty-third meeting of the Pacific Coast

Entomological Society was held at 2:30 p.m. on October 7, 1944,

in the entomological laboratories of the California Academy of

Sciences. The following members were present: F. P. Keen, E. G.

Linsley, R. F. Smith, J. L. Gressitt, N. F. Olson, A. E. Michel-

bacher, C. D. Duncan, E. C. Van Dyke, P. Moorhead, and R. W. L.

Potts. Visitors were present as follows: E. A. Steinhaus, A. L.

Burroughs, P. H. Arnand.

The minutes of the previous meeting were read and approved.

The Membership Committee proposed Prof. H. A. Scullen for

membership in the Society. He was duly elected.

Dr. E. C. Van Dyke exhibited six boxes of mounted insects from

the more than fifty thousand specimens sent back by Dr. E. S.

Ross from New Guinea.

Dr. C. D. Duncan exhibited an extremely interesting collection

of unusually grotesque neotropical Membracidae. Pie also called

attention to the discovery at Mt. Hermon in Santa Cruz County,

California, of a large colony of Vermelio, a genus which had been

previously regarded as restricted to higher elevations in the state.

Mr. R. F. Smith reported a large migration of Aglais calif or-

nica late in the summer of 1944 and called attention to the fact

that he was preparing a summary of the literature pertaining to

January, 104 . 5 ] PACIFIC COAST ENT. SOCIETY

migrations of this species and would welcome any first-hand ob-

servations on the subject. Mr. F. P. Keen remarked that early in

the season there was a serious outbreak of the caterpillar on

Ceanothus in the Shasta region.

Mr. Keen also commented that in general this had been a year

of minor barkbeetle activity along the Pacific Coast but that de-

foliators had been serious in certain local areas. He mentioned

particularly outbreaks of Perionia variana, and a lodgepole pine

sawfly {Neodiprion sp.). The latter species was responsible for

the defoliation of about 25 square miles of lodgepole pine in Ore-

gon, as a result of an infestation which had apparently been

building up for at least three years.

In response to a question by Dr. Linsley, Mr. Keen commented

on an outbreak of the Englemann spruce beetle in the Grand Mesa

and White Mesa, Colorado. The species had not previously been

observed in epidemic numbers for a great many years.

Mr. Keen then presented Prof. Edward A. Steinhaus of the

Department of Bacteriology, University of California, who deliv-

ered an illustrated lecture on Intracellular Organisms in Insects.

Prof. Steinhaus pointed out that some of the most interesting of

all biologic relationships between microorganisms and insects are

those of intracellular parasites and symbiosis. Within the tissue

cells of many arthropods may be found apparently living, non-

pathogenic organisms. These intracellular organisms frequently

live in specialized cells or structure called mycetocytes and myce-

tomes. Various types of these were discussed and illustrated by

lantern slides. These organisms are not only transmitted directly

from one generation to the next but they are also present in every

representative of the species. In the case of the aphids the path

of transmission of the symbiotes was traced from the follicular

epithelium of the parent to the definitely formed mycetome of the

offspring. In certain bostrychid beetles, the organisms from the

mycetomes invade the lobes of the testes, multiply, and mix with

the sperm. They then pass through the micropyle of the fully

formed egg during its passage to the outside, and thus the infec-

tion is accomplished. Transmission of the symbiotes via the out-

side of the egg shell was shown in the case of Stegobium paniceum.

Other intimate and little understood relationships were discussed

and illustrated. For the most part these intracellular organisms

are of the nature of bacteria or yeasts, and occasionally fungi.

As to the role of these symbiotic microorganisms in the life

processes of the host very little definite information is at hand.

In some cases, at least, the symbiotes apparently supply vitamins

necessary for normal insect development.

After a discussion of Dr. Steinhaus’ paper, the meeting was

adjourned. — E. G. Linsley, Secretary.

The Membership Committee proposed Prof. Carl J. Drake, Dr.

E. A. Steinhaus, Mr. Robert P. Allen, and William Peterman, Inc.,

for membership in the Society. They were duly elected.

President Stewart asked for the annual report from the Treas-

urer. Dr. Miller presented the report and Dr. Van Dyke moved

that the report be accepted and that the Society extend its thanks

to Dr. Miller for the excellent work wihch he had performed in

connection with this office. The motion was seconded and unani-

mously passed.

The Nominating Committee proposed the following officers for

1945: F. P. Keen, President; C. D. Duncan, Vice-president; E. G.

Linsley, Secretary, and R. C. Miller, Treasurer. The motion was

made, seconded and passed that the Secretary cast a unanimous

ballot for their election.

Dr. Stewart turned the chair over to the new president, Mr.

Keen, after expressing appreciation to the officers and members

for support which had been extended to him during his term of

office and after calling attention to the great responsibility which

scientific societies must assume at present in order to maintain

standards and culture in the face of strong pressures to the con-

trary.

Dr. Van Dyke exhibited a copy of G. V. Hudson’s “The Butter-

flies and Moths of New Zealand” which the Academy had recently

received as a gift from the New Zealand legation in Washington.

Dr. Steinhaus mentioned his interest in bacterial, protozoal and

viral diseases of insects and expressed the hope that members

would assist him in the collection of material for study.

Mr. Keen then presented Dr. Stewart who delivered a most

thought-provoking address entitled “Professional Training in En-

tomology” (seep. 1).

Following Dr. Stewart’s address, the meeting adjourned. — E. G.

EVOLUTION OF MOUTH PARTS IN DIPTERA

A COUNTER CRITIQUE

BY RICHARD B. GOLDSCHMIDT

University of California, Berkeley

In a recent review of that homoeotic mutants of Drosophila my

former student, C. Villee, made some statements on homologies

of Dipteran mouth parts (taken over from Bridges and Dobzhan-

sky’s paper on the Drosophila mutant proboscidea ) . Later he

commented briefly, though rather dogmatically, on the evolu-

tionary significance of those mutants, following the present au-

thor’s viewpoints as developed in a recent book (1940). Villee’s

remarks on both these topics have been strongly criticised by the

excellent entomologist, G. F. Ferris. As this criticism does not

involve questions of entomological detail unknown to the out-

sider, but broad and general problems of evolution it ought to

be considered carefully and discussed by non-entomologists.

Ferris’ first, rather acid critique was directed against the

geneticist’s claim to have established some decisive arguments in

controversial problems of homology. The organ under discussion

is the oral lobe or labellum in the proboscis of Diptera. Old

authors (Lowne) homologized it to the maxillae, but this had

been given up long' ago by dipterologists, some of whom consid-

ered the oral lobes as derived from the paraglossae while the

more modern view derives them from the labial palpi. Villee,

repeating remarks made by Bridges and Dobzhansky, pointed out

that the mutant proboscipedia with antennae or tarsi instead of

the oral lobes proves definitely that Lowne was wrong. He did

not further discuss the development of the problem subsequent

to Lowne’s paper because part of the literature had been quoted

by Bridges-Dobzhansky whom he followed in his discussion.

Ferris rebuked rather strongly the geneticist who assumes the

right to decide upon a problem of comparative morphology. He

wrote: “So far, so good. This is merely a fact which is well

enough known to any morphologist of the present day and the

contribution of genetics is not necessary to confirm it.” Further,

after quoting Villee’s remark that the mutant shows that the oral

PAN-PACIFIC ENTOMOLOGIST

[VOL. XXI, NO. 2

lobes are homologous to labial palpi, he said: “Villee seems to

have been unaware of any work that has been done in the mor-

phology of insects since the date of Lowne (1890), for evidence

has been presented on morphological grounds alone, by at least

three authors, which demonstrates beyond any reasonable doubt

that the ‘oral lobes’ of flies are in fact nothing more than the

labial palpi. We should not object to such confirmation of our

morphological ideas as we can gain from geneticists . . . . ”

This discussion, I think, has a significance beyond the present

bone of contention. The present writer, who had passed the in-

criminated sentences for publication though overlooking the lack

of reference to the modern interpretation, cannot be accused of

lack of understanding for the morphologist’s point of view,

having spent many years of his life in work on comparative mor-

phology and having been guilty of many more or less good

phylogenetic homologisations on the basis of such work. But, I

think, everybody ought to realize that problems of homology can,

in many cases, be settled only by experimental, embryological,

or genetical work. By comparing many different types the mor-

phologist comes to definite conclusions the correctness of which

increases with the quantity of the material available. Sometimes

there will be no reasonable doubt for a homologisation and the

actual proof furnished by the experimental work might amount

to carrying owls into Athens. To take an example: The homo-

logisation of the halteres of flies with wings is beyond any rea-

sonable doubt. Thus the fact that a haltere may be transformed

into a wing ( Drosophila mutant tetraptera ) or a wing into a

haltere (mutant telraltera) is not needed to establish the homol-

ogy. But there are many homologies for which the situation is

different and different schools draw different conclusions. To

take again an example: There has been much discussion and di-

vergence of opinion regarding the homologies between female

and male genital armature and ducts in Lepidoptera. Some points

could be settled by the study of development, but other homol-

ogies could only be finally established (by Goldschmidt and

Kosminsky) when the geneticist produced all grades of inter-

sexes in which the transformation of one part into the other (or

the impossibility of it) could be seen. The supreme criterion of

homology is experimentally transforming one member into the

other.

GOLDSCHMIDT — MOUTH PARTS IN DIPTERA

In spite of Ferris’ claims to the contrary and the condescend-

ence apparent in the above quotation, I hold that the situation is

not much different in the material under discussion. Though, no

doubt, the present trend among dipterologists is to assume that

the labella are the homologues of labial palpi, it cannot be over-

looked that very good entomologists have held (and might still

hold) that the proper homologues are the paraglossae. In the

most recent general presentation of the subject known to me, the

Dipterologist Hendel writes (1936) : “ A generally accepted

homologisation does not yet exist. 1 According to Peterson sub-

mentum and mentum are united more or less closely with the

membrane of the sixth head sternite. He calls the boatshaped

chitinous plate located ventrally in the labial proboscis the

theca; he homologises the labella with the paraglossae as do

Newport and Gershfield. I follow in the homologisation of the

labial parts those authors who interpret the just mentioned ven-

tral chitin plate of the trunk as the mentum, and the labella as

labial palpi (Burmeister, Becher, Hewitt, Frey) Almost at the

same time Snodgrass (1935) writes in his well-known text: “The

labella . . . have been generally regarded as the paraglossae,

apparent rudiments of the glossae being sometimes present be-

tween them; but Crampton . . . has given reasons for believing

that the labellar lobes are the labial palpi. Palpi, however, are

typically provided with antagonistic muscles. The lobes of the

fly labrum have usually only one muscle inserted directly upon

it.” Thus the standard entomological text does hardly consider

Crampton’s (and others) homologisation established “beyond

reasonable doubt” and actually is leaning toward the other side.

To these statements I may add that among the old and new

authors who agree with Frey are Erickson (1840), Kraepelin

(1880), Griinberg (1907), Crampton (1923-25), Jobling (1927).

Among those who are opposed to the homology of the labella

with labial palpi are Wesche (1904), McGillivray (1924),

Otanes (1922). The detailed and animated polemic on the sub-

ject between Crampton and McGillivray proves sufficiently that

a final decision satisfying everybody cannot be reached by mor-

phological comparison alone. (Professor E. G. Linsley has

kindly drawn my attention to Crampton’s most recent paper,

1 Translated from the German ; italics mine.

PAN-PACIFIC ENTOMOLOGIST

[VOL. XXI, NO. 2

1942, in which he summarizes the data in favor of his interpreta-

tion and gives clearer drawings of mouth parts of Mecoptera and

Diptera than contained in former publications.)

Thus to me these statements and facts convey the idea that the

problem is still controversial and not solved “beyond any rea-

sonable doubt” by comparative morphology. The genetical facts

reported above furnish a complete proof of the interpretation.

The geneticists who claim this (following Bridges and Dobzhan-

sky, the latter himself trained as an entomologist) do not want

to parade any superiority but just make the proper use of a

superior tool, which they happen to wield.

There is a second part to Ferris’ criticism. Villee had stated,

following certain of the present author’s views (1940) that the

homoetic mutants demonstrate that it is not necessary for ex-

ample, to assume that the oral lobe has been developed from the

biting parts of lower insects by accumulation of small steps.

Rather a single mutation affecting early embryonic processes may

have effected this in one step. He adds, somewhat overshooting

his mark, that animals with intermediate mouth parts would not

have been able to feed. 2 To this Ferris remarks: “All of which

can but wring an agonized scream from the depths of a mor-

phologist’s soul. The writer of that statement, like most non-

entomologists, seems to be quite unaware of the fact that there

are thousands upon thousands of species of flies other than

Drosophila melanogaster and that these flies present probably

hundreds of those various ‘intermediate types of mouth parts’

condemned by him, with which they get along very nicely. These

degrees of development range from the perfectly normal, although

but two-segmented palpus in the closely related and possibly even

antecedent order Mecoptera through various modifications up to

the highly bulbous palpi of the most specialized flies ...” This

statement clearly characterises my viewpoint, as repeated by my

student, as based upon ignorance. But it may be assumed that a

former, though rather amateurish collector of insects, including

Diptera and Mecoptera, is familiar with the existence of flies

other than Drosophila. Recollecting the structure of the many

mouth parts of Diptera which I had once dissected in entomol-

ogical classwork, I was unable to remember having seen all these

transitions. Therefore, I asked Ferris by letter to name a few of

2 My own statement (1940) of which this is a paraphrase says that gradations

between generalized and specialized types would have died of starvation.

APRIL, 1945 ]

GOLDSCHMIDT MOUTII rARTS MrTEIfcA

the hundreds of transitional stages which he had in mind and to

help me to collect information on them. As no answer was re-

ceived, I took the trouble to search for these transitions, believing

that there might be an alternative to ignorance so complete that

it makes souls scream: namely a different evaluation of what

might be considered a transitional stage.

Again I consulted first the most recent monograph on Diptera

by Hendel and found the following statement: “The labella or

labial palpi are separate externally in primitive forms, inde-

pendent but connected basally by a hyaline middle part which

may be swelled. This connection has become more close in the

course of evolution, especially in the Calyptrata.” This statement,

in my opinion, covers the crux of the matter. In the papers of

Peterson, Frey, Crampton and Jobling descriptions can be found

of the mouth parts and their comparative interpretation and in

some of them detailed, in others only semi-diagrammatic figures.

The interest centers upon the forms which are considered primi-

tive by dipterologists. Crampton studied what he calls the most

primitive living representative of the order Diptera, Tanyderus.

Frey (1913) analysed a series of primitive types as Bolitophila,

Gnoriste, Sciara, etc. Jobling (1927) discussed Culicoides. In

all these cases we have the typical elongated labium whatever the

homologisations of the parts with the mentum, submentum and

palpiger of lower forms may be, much of which is controversial.

The labella may still show traces of two segments, but they are

bulbous, connected by a hyaline membranous middle part which

can be swelled by blood pressure. The outer part is better chit-

inized and supported by chitinous arcs. Altogether the labella

and their supports are incorporated into the functions of the

proboscis into which the mouth parts combine. There are cer-

tainly many variations in detail but as a whole the principle of

a dipteran labium is present from the beginning as far as I am

able to find out. The dipterologists agree that these mouth parts

are derived from those of the Mecoptera. But the only condition

of transition which I can find in Diptera is the rudimentary seg-

mentation of the primitive labellum. Thus it looks to me as if

the decisive step to “dipterisation” was a single one, whether

derived from a Mecopteran type, or if this is a blind side alley,

from a more primitive one. It is possible that Ferris laid less

stress upon the first establishment of the Dipteran type in his

PAN-PACIFIC ENTOMOLOGIST

[VOL. XXI, NO. 2

“hundreds of transitional stages,” though he starts his series with

the Mecoptera as first transitional types. Villee had only spoken

of the change of the primitive biting mouth parts (esp. labrum)

into the Dipteran type. Probably Ferris alluded to the develop-

ment of the specialized types, e.g., in Drosophila, from the prim-

itive dipteran type. If one arranges the labella of many types of

flies according to e.g., the number of pseudotracheae or the sense

organs or the shape, one can certainly put them into a series,

though not one of hundreds of steps, and certainly not a phylo-

genetic one. It has frequently been pointed out in evolutionary

discussions that variable objects may be arranged in a series

whenever quantitative variants are involved, but without any

meaning in regard to the derivation of one from the other. If we

take a crude example; we might arrange all brass instruments

into an evolutionary series according to the number of valves or

the bending of the tube or the size or all of them together. Is this

an evolutionary series? There is certainly no transition between

a tuba and a valve instrument. The last phylogenetic step, the

saxophone, has probably not been derived from a horn or cornet,

but from the constructive principles of some wood wind without

any transitions. In the same way the existence of a labellum

with one, two, four, many pseudotracheae in different Diptera,

specialized for different ways of feeding does not imply that this

represents an evolutionary series. Just as some mutation must

have once produced the primitive two pseudotracheae from a

form without them, also four of them may have originated at

once by a different mutation. The same argument applies to all

other specializations. Genetics has taught us that in series of

multiple alleles of one character showing all transitions, e.g.,

from large wings to absence of wings, one mutational step may

produce the extreme as well as any intermediate. In the case

under discussion it has been shown that one mutational step

transforms a highly specialized labellum into a segmented ap-

pendage. This makes us suspicious of graded series of evolution

assembled from numerous variants going in all directions. But

these are details. The decisive point is the first step from a biting

labium to a sucking one, from a palpus to a labellum. For this

I have, thus far, failed to find the numerous transitional steps,

though one might say, comparing as types, Periplaneta, Panorpa

and primitive fly, that the Mecoptera have gone in the direction

GOLDSCHMIDT MOUTH PARTS IN DIPTERA

of Diptera in some respects but failed to take the decisive step

which I can consider only as a single one. But even if the

Mecoptera were the actual ancestors of the Diptera and the two-

jointed palpus and rudimentation of glossae and paraglossae and

the occasional presence of pseudotracheae (if true) were one of

the proofs of this, the flat, biting type of mouth parts, though

soft and reduced, is not yet a beginning of a dipteran type which

FLYING STAGE OF THE DEER LOUSEFLY, LIPOPTENA

DEPRESSA (SAY), IN CALIFORNIA

(Diptera, Hippoboscidae)

BY JOHN EDWARD HARE

University of California, Berkeley

Lipoptena depressa (Say) is a common bloodsucking ecto-

parasite of deer (genus Odocoileus ) in western North America.

As in other Hippoboscidae the females are larviparous, deposit-

ing at short intervals single full-grown larvae which immediately

pupate. 1 The pupating larvae are smooth and clean, dropping

from among the host hairs to the ground where the entire pupal

period is passed. At emergence the imago possesses fully devel-

oped though fragile wings and flies among the trees in the wood-

land haunts of the host. This stage of the parasite, here called

the volant, survives but a few days in the absence of the normal

host. Upon reaching a deer, the volants immediately crawl be-

tween the hairs and begin to suck blood. Here they remain as

permanent parasites for the rest of their lives, soon losing the

wings by a simple process of wear.

In the course of a detailed study of the complete life history

of this species over a period of six years, numerous observations

have been made of the occurrence and behavior of the volants in

California. The present paper is concerned only with the volant

phase, i.e., that portion of the life cycle beginning at emergence

from the puparium, and the subsequent events which lead to the

finding of a host.

Little published information exists on the biology of L. dep-

ressa, and this almost exclusively concerns the parasitic stage on

the deer. Spencer (1939) believed that young flies probably

emerge at intervals throughout the spring in British Columbia,

basing his conclusions on a study of mature parasites taken from

deer carcasses in November. Bequaert (1942) mentions that

flights of many winged, newly emerged individuals of both sexes

are often observed in the fall, when they frequently alight on

people and are said to bite readily. Cowan (1943) states that

1 The gestation period of L. depressa is three to four days as found by expe-

riments with captive deer, soon to be reported. Cowan (1943) estimated a two

months period; Hei-man ( Calif . Fish & Game, 31 (1),1945) has repeated this figure.

volants often alighted on his clothing, and from rearing experi-

ments on puparia deposited by females removed from dead deer,

he concluded that emergence in the wild occurs from June to

November in British Columbia. Herman (1945) includes photo-

graphs of the volant, puparium and parasitic female of L. dep-

ressa, as Neolipoptena ferrisi (Beq.)

I have observed and collected free flying volants in California

at the following localities : Binkley Ranch, near Kelseyville, Lake

County; 17-mile Drive, Carmel, Monterey County; Sespe Gorge,

near Ojai, Ventura County; Mt. Diablo, Contra Costa County;

Redwood Canyon and Strawberry Canyon, Alameda County. No

attempt was made to survey the entire state to establish the geo-

graphic limits of distribution, but in general it may be said to

coexist with that of the deer hosts.

Volants of Neolipoptena ferrisi (Bequaert) ( Lipoptena subu-

lata Ferris and Cole) have been collected along with L. depressa

on only two occasions (Lake County, Ventura County) and then

in very small numbers. N. ferrisi, although it accompanies L.

depressa infestations on deer in many parts of California, ap-

pears to be more limited in distribution, at least with respect to

coastal California.

Bequaert (1937, 1942) lists specimens of L. depressa from 29

of the 58 counties of California, from Humboldt, Trinity and

Lassen in the north, to Orange, Riverside and San Diego in the

south, and from the Pacific Coast to the Sierra Nevada Mountains.

The races of Odocoileus hemionus (Mule and Blacktail deer) are

widely distributed in California, according to Dixon (1934) and

Cowan (1936), and are absent only from the hot interior valleys

and from the Great Basin Desert region of southeastern Califor-

nia. The presence of infested deer in a given area, as determined

by examination of carcasses during the hunting season, would

indicate the occurrence of the volant stage in the same general

area. Wherever intensive search was made in localities known to

be frequented by deer, volants have sooner or later been found.

In certain cases, notably Carmel, Mt. Diablo and Strawberry

Canyon (Berkeley) , many hundreds of volants have been ob-

served and collected at frequent intervals during the warmer

months of the year.

The conclusions here presented are based on a total of over

70 daily field trips, of which approximately 50 refer to the

PAN-PACIFIC ENTOMOLOGIST

[VOL. XXI, NO. 2

Strawberry Canyon, Alameda County, locality, which served as

the primary field station for the observation of wild volants.

Seasonal Occurrence

My earliest records for the year for the appearance of L. dep -

ressa volants are: March 26, 1941, 35 flies, Mt. Diablo; March

28, 1942, 24 flies, Mt. Diablo; March 18, 1944, 3 flies, Berkeley

hills. Trips made to these localities during January and Febru-

ary of several years were negative. From March onward the

volants appear in ever-increasing numbers as the weather grows

warmer, until a peak is reached in the latter part of July, at

which time as many as 200 flies have been caught in one hour, in

an area of one acre. In the Berkeley station, for which I have the

most complete records, the volant population appears to diminish

during the months of August and September. Volants continue to

occur in fairly good numbers on warm days in October and

November, and four flies were caught flying as late as December

8, 1943. Volants have also been collected in August in Ventura

County, September in Lake County, and October in Monterey

County. On October 5, 1938, the flies were exceedingly numerous

along 17-Mile Drive, Monterey County, and over 500 specimens

were collected by three collectors in less than two hours. This

indicates that the seasonal peak may extend into late fall in some

localities.

Volant and Host Ecology

It is to be expected that the ecological niche of the volant

stage of L. depressa integrates with that of the host, since this

stage of the cycle is devoted entirely to bringing it, fresh from

emergence from the puparium in the forest floor, into contact

with its host.

Bequaert (1942) gives the following as the normal, breeding

hosts of Lipoptena depressa: Odocoileus hemionus hemionus

(Rafinesque) — Rocky Mountain Mule Deer; O. h. columbianus

(Richardson) — Columbian Blacktail Deer; Odocoileus virgini-

anus leucurus (Douglas) — Western White-tailed Deer; Cervus

canadensis (Erxleben) — the Wapiti or American Elk. The nor-

mal ecological pattern in California concerns races of Odocoileus

hemionus only. Bequaert’s list of specimens examined includes

a record from Odocoileus hemionus calif ornicus (Caton), and

APRIL, 1945 ]

HAKK — LIFOrTKHA UEritESBA

in the absence of host identification of many other series of

specimens, the localities given would indicate that 0. h. inyoensis

Cowan and 0. h. fuligirmtus Cowan may also be normal hosts of

L. depressa (based on Cowan’s study of the distribution of Pacific

Coast Deer, 1936) . The only California race of Odocoileus

hemionus for which there seems to be no evidence, direct or in-

direct, of infestation by L. depressa, is 0. h. eremicus (Mearns) ,

the Burro Deer. According to Cowan, this race is found in Cali-

fornia only in the extreme southeastern corner of the state, in

the Lower Sonoran life-zone, chiefly below 1500 feet. This race

of deer is isolated from the coastal races by the Colorado Desert,

and has habits which are different from the hemionus Rassenkreis

as a whole. Blacktail deer in California inhabit mainly the

Transition and Boreal zones, but are also abundant in the Upper

Sonoran chaparral belt of the coastal region, from Mendocino

County southward. Cowan states that in the coastal regions the

habitats favored are Redwood, Scrub Oak, and chaparral, while

in the Sierran region the foothill chaparral belt and the Yellow

Pine-chaparral association support the bulk of the population.

Dixon (1934) considers California Mule Deer to be characteristic

inhabitants of the Yellow Pine and White Fir forests in the cen-

tral Sierran region, and has observed herds at elevations up to

11,000 feet.

From the above account it may be concluded that deer are to

be found under a wide variety of floristic conditions, at all ele-

vations up to at least 10,000 feet, and absent only from the most

arid portions of the Lower Sonoran zone (cf. Grinnell, 1939).

At the collecting localities mentioned above, volants of L.

depressa were collected in a number of different plant associa-

tions: Digger Pine, Pinus sabiniana, Lake County; Monterey

Pine, Pinus radiata, mature growth — Monterey County, young

growth — Alameda and Contra Costa counties; Cedar, Chamae-

cy paris thyoides, young plantings, Strawberry Canyon, Alameda

County; Redwood, Sequoia sempervirens, Redwood Canyon, Ala-

meda County; Pine-Oak-Juniper association ( Pinus sabiniana-

Quercus douglasii-Juniperus californica ) Mt. Diablo, Juniper

Camp, Contra Costa County; Laurel-Oak association ( Umbellu -

laria calif ornica-Quercus agrifolia ) Redwood Canyon; Willow-

wild rose thicket (Riparian mountain meadow) Ventura County.

The volant habitats are all mesophytic in nature, when con-

PAN-PACIFIC ENTOMOLOGIST

[VOL. XXI, NO. 2

trasted with the adjoining grassland and chaparral formations

usually present at the same localities, but which are almost uni-

versally negative with respect to volants. Among the factors

which appear to be important are, 1) moderate to dense shade

(which directly modifies the temperature relations and the evap-

oration rate) and 2) shelter from wind. The shade factor is also

involved in the production of a light-shade edge pattern which is

commonly present in the volant habitats. The ecological rela-

tions of the light-shade edge will be discussed later.

Deer beds and other fresh sign were commonly present in the

same vicinities as the highest volant densities. The highly local-

ized occurrence of volants in these areas suggests that the flight

range is quite limited.

In localities where the volants are habitually present, and

during the warmer hours of the day, considerably more flies can

be caught on the body of the collector than in a net. It is more

accurate to say that the flies seek out the collector than the

reverse. The volants have the habit of alighting suddenly on

almost any part of the body, clothed or exposed. Here they pause

for a fraction to several seconds, and then just as suddenly fly

off again. By acting quickly, it is possible to capture the flies

while they remain on the skin or clothing, by grasping them

lightly between the fingers, or by inverting a collecting tube

over them. The volants are small (3 mm.) flat, brown flies, with

tough leathery bodies which can withstand considerable pressure

and handling without injury, other than occasional tearing of

the delicate wings.

Localities were surveyed simply by traversing, meanwhile be-

ing on the alert for any volants which might alight on the body.

Specimens were obtained in this way even when the population

density was so low that continuous beating for long periods did

not yield a single fly by the conventional method. Sweeping and

beating were useful during cold or wet weather or in the very

early morning hours, when inactive or sluggish volants could be

swept from edge foliage of trees, shrubs or grass in the same

localities.

Of a total of over 600 individually recorded observations on

volant behavior, approximately 17 per cent alighted on my body

while I stood or moved in direct sunlight, another 17 per cent

while in deep shade, and the balance, 66 per cent, occurred in or

close to the interzone produced at the edge of the distinct shadow

cast by the trees which border the woodland formations. The

occurrence of volants at this light-shade edge was very character-

istic, and the highest frequencies of landings always took place

here. Landings were most numerous when moving from shad-

ows outward to bright sunlight, less when moving along the

shadow edge, and least when moving from sunlight into shadow

at right angles to shadow edge.

A similar behavior has been reported for the volants of

Lipoptena cervi in Germany, by Schroeder (1911) who describes

how over 100 specimens were caught as they alighted on several

people crossing a clearing in a forest in Pomerania, in October.

No details were given by Schroeder, but to collect that number of

volants by hand requires time and care, and one may assume

that the members of his party moved about the clearing while

awaiting the flies.

The behavior of L. depressa volants may be attributed to the

interaction of a number of responses, which probably include a

phototaxis, form vision and light adaptation, and perhaps also

detection of moving objects. Experiments have been conducted

on the photic responses and other orientations of the volants, as

well as on newly established and old feeding flies, and these will

be reported in a later paper.

It is interesting to note that the behavior of tsetse flies, which

in many ways are ecologically equivalent to the volant L. dep-

ressa, resembles closely that described above. Schwetz (1919)

states that Glossina fusca Walker occurred almost exclusively

along paths and roads bordering forests. G. palpalis R.-D. ac-

cording to Fiske (1920), when in search of a host, follows game

trails, lake shores and stream banks, and in general follows the

line between shadow and sunlight, being averse to penetrating

shadow where light is not evident beyond, and vice versa.

Swynnerton (1936) describes the “vegetational concurrence”

required by G. morsitans Westw. for example, which requires

both a savannah of sufficient shade value, and open glades in

which to hunt prey. The feeding grounds are on sections of paths

or glades and passes between thickets. Jackson speaks of the

same species (1941) living in restricted “ambits”, congregating

along the “contact line of woodland and swamp, often in a special

interzone including trees not found in either of the other types”.

PAN-PACIFIC ENTOMOLOGIST

[VOL. XXI, NO. 2

He states that the interzone provides good visibility and attractive

conditions for the hosts, while the shadier woodland offers breed-

ing and resting haunts.

The habits of the hosts of L. depressa, so far as they are

known, fit into the volant pattern very well. Dixon (1934) states

that mule deer in California spend the middle of the day bedded

down in cool secluded nooks, such as groves of pines provide.

Other bedding places are wild plum thickets, rocky ridges and

hemlock thickets. To reach these spots, the deer must travel from

the early morning feeding grounds in meadows and chaparral-

covered hillsides, traversing patches of woodlands and the forest

edges on the way. Here the volants have adequate opportunity to

alight on the slowly moving or even momentarily stationary deer

still browsing as they go. The bedding-down places are usually

close to the forest edge, as the wary animals prefer a spot with

an unobstructed view on one or two sides. In late fall and

winter sunny nooks are sought for sun baths (Dixon, 1934,

p. 35). As the shadows shift, the deer change their position, and

move to other sun-bathed spots. This is precisely where volants

habitually occur. The responses to temperature are also condu-

cive to the rendezvous. Volants tend to retire into the deeper

shadows on the warmest summer days, but on cool spring and fall

days, the flies congregate in the warm sunny glades bounded by

dense shadows. I have found by personal experience with cap-

tive blacktail deer that these animals are extremely light-shy on

hot summer days, and seek the cool shadows whenever permitted.

The reverse is true in cool weather.

Diurnal Cycle

During the night and in the first hours after dawn, volants

may be recovered from foliage in the same localities where

flights are made during the day. Crawling activity evidently be-

gins as soon as light is present, when the temperature permits

sluggish movement. Sluggish volants, their bodies wet with dew,

have been observed dropping from branches of trees overhead as

early as 5 A.M., just before dawn, on a cool foggy morning

(13° C.). Volants kept at 10° C. overnight, move the legs and

attempt to crawl almost immediately when brought into light.

Flights have been observed as early as 6:30 A.M. (still air

temperature in this particular case was 18.0° C.) when the sun

APRIT., 1Q4.E]

HARE— LTPOPTENA DEPRESfiA

was one hour above the horizon. The volants are also active on

days with low fog, temperature permitting. The coolest condi-

tions under which volants were seen flying, were recorded on

December 1, 1943. From 1:20 P.M. to 2:30 P.M. the shade air

temperature was 12.7—13.0° C. while the sunny air temperature

was 18.5-23.0° C. Six volants were caught alighting on my body

during this time. On another occasion, flight was slow and

clumsy at 14-17° C., on a day with a low fog, which excluded

the possibility of a warming effect by direct sunlight. The flies

were seen to vibrate their wings several times before taking off

in flight. This does not happen on warmer days, and suggests

that under the cooler conditions, it is necessary for the volants

to raise the internal temperature for proper function of the flight

muscles, as pointed out by Wigglesworth (1939, p. 90) for other

insects.

Optimum range of temperature for flight under field condi-

tions appears to be 18-24° C. When the shade air temperature

exceeds 25° C. the number of flies appearing at the forest edge

decreases, as compared with average numbers caught on cooler

days. The few flies present tend to remain in the deep shade,

where they continue flying and resting activities. A similar type

of reaction has been described for Glossina morsitans by Jack

and Williams (1937) who found that as the temperature rises

above 32° C. the response to light changes from photopositive

to photonegative. They also showed that lowering the humidity

lowers the threshold for this change in photic response.

Volants continue to make short flights throughout the day,

frequently alighting on trunks and branches of trees, foliage and

grass, where they rest briefly, and fly off again. One receives the

impression of almost constant activity on the part of the flies.

This restless behavior continues when the volants are put into

dry collecting vials, where rapid crawling and flying still occur.

Only with the coming of darkness and a drop in temperature

does volant activity cease. Those flies surviving a longer period

of starvation remain inactive on vegetation for the night and

resume the search for a host the following day.

Cowan (1943) kept seven newly emerged volants of L. dep-

ressa over damp sand at room temperature. The maximum period

of survival was 72 hours, average 57 hours. I have conducted

PAN-PACIFIC ENTOMOLOGIST

[VOL. XXI, NO. 2

numerous survival experiments with reared as well as wild

volants, and a brief summary of results will be given.

Volants of L. depressa lived from one to eight days after

emergence from the puparium. The maximum survival was ob-

tained Avith a group of reared flies emerging from normal puparia

collected from captive deer. A total of twenty emergents were

kept in small (20x6 mm.) vials plugged with cotton, in normal

laboratory daylight, at room temperature and humidity: 50 per

cent mortality at 4% days, maximum survival, 1 fly 8 days.

Wild caught volants, kept at 84 per cent relative humidity and

22.0-22.8° C. lived up to 3 Yz days, 50 per cent mortality at 1%

days, when kept under daylight conditions; when kept in dark

cabinet, other conditions same, wild volants lived up to 6 days,

50 per cent mortality at 3% days. At 98 per cent R. H. and

16-19° C. wild volants lived up to 6 days, 50 per cent mortality

at 4 days, when kept in dark cabinet. Lowering the humidity in-

creases the mortality rate and shortens the maximum survival

time. At room temperature and humidity, 75 per cent of wild

volants kept in large glass jars die the first day. Factors which

decrease the activities of the flies, hence the energy expended,

tend to increase the maximum survival time and to lower the

mortality rate. Such factors include: limiting the space for walk-

ing and flying, cutting down or excluding light, and lowering

the temperature. A similar relationship was found for Pseudo-

lynchia canariensis (Macq.) [ P . maura (Bigot) ] by Prouty and

Coatney (1934), where longevity without food was 77-109 hours

in direct proportion to the energy used up in activity.

Under natural conditions, the volant L. depressa may be ex-

pected to live and remain active for one to four days. Rearing

experiments with captive deer indicate that 50 per cent of those

volants still fairly active 4 days after emergence, can successfully

establish on the host. One-day-old flies are 75 per cent successful.

NEW GENERA AND SPECIES OF TRICHOPSENIINAE

FROM AMERICAN AND AUSTRALIAN TERMITE NESTS

(Coleoptera, Staphylinidae)

BY CHARLES H. SEEVERS

Research Associate, Chicago Natural History Museum

The staphylinid beetles of the subfamily Trichopseniinae con-

stitute a small but very interesting element of the alien insect

fauna inhabiting termite ' colonies. Among the termitophilus

beetles they are notable chiefly because of their association with

the more primitive termites, and for their wide geographic range

which includes both hemispheres. The great majority of groups

of termitophilous insects are restricted to one hemisphere or the

other, but the thirteen known Trichopseniine species were found

in Argentina, British Guiana, the United States, Java, Sumatra,

and Australia.

The intent of this paper is to describe the new forms which

have been acquired since an earlier report 1 in which I proposed

that the Trichopseniinae be given subfamily status because of

their distinctive metasternal structure, hind-leg articulation, and

male genitalia.

The most noteworthy addition to the subfamily is its first

Australian representative, the bizarre genus, Mastopsenius. The

peculiar facies of Mastopsenius scarcely indicates relationship to

Trichopsenius, but this is in line with the subfamily tendency for

each genus to develop its own distinctive habitus. The diversity

within the group is more apparent than real for in most respects

the basic morphological features are rather similar. The host

relationship of Mastopsenius is especially interesting, for its

host, Mastotermes darwiniensis Froggatt, is the most primitive

of present-day termites, and sole living representative of the

family Mastotermitidae, while the other Trichopseniinae are

guests of the Rhinotermitidae.

With more material available for study, it is now evident that

the North American genus Trichopsenius is comprised of at least

phylinidae of the subfamilies Aleocharinae and Trichopseniinae (new subfamily).

four species instead of one. The literature records Trichopsenius

depressus Leconte as ranging from Massachusetts to California,

but closer study shows that all of the specimens are not con-

specific. It is clear, also, that some degree of host specificity

exists, and that each species of Trichopsenius is restricted to one

or a few species of Reticulitermes.

The staphylinid beetle, Schizelythron javanicum Kemner * 2 ,

collected from the nest of Schedorhinotermes javanicus Kemner,

at Buitenzorg, Java, should be included in the Trichop seniinae

rather than in the Aleocharinae where placed by Scheerpeltz 3 .

Although I have not seen this species, I have no doubt of its re-

lationships; the distinctive Trichopseniine metasternal and hind-

leg characters are plainly evident in Kemner’s illustrations.

Schizelythron derives its name from a remarkable character ;

each elytron is split lengthwise from near the base to the apex,

and the lateral half diverges strongly from the medial part.

I am very grateful to Dr. A. E. Emerson for determining the

host termites cited in the paper, and to the following men for the

gift of specimens or for arranging loans: Dr. R. E. Blackwelder

of the United States National Museum, Dr. M. F. Day, Dr. Emer-

son, Mr. C. A. Frost, and Dr. M. W. Sanderson of the Illinois

Natural History Survey.

medially; mesosternum large, with a slender carinate process

meeting a similar process of the metasternum between the middle

coxae; metasternum relatively short caudad of the middle coxal

cavities, and relatively narrow, its width from median line to side

margin scarcely greater than the width of the large metepister-

The position of Mastopsenius within the subfamily is not clear

at this time. Recognition of the genus should offer no difficulty

in view of its distinctive form, its antennal, pronotal, and elytral

peculiarities, and its host relationship.

do more than suggest host specificity. We have no idea of the

this is scarcely indicative, for xenoflavipes appears to be re-

placed by frosti n. sp. in the eastern states.

[VOL. XXI, NO. 2

This species differs from those of the eastern states in being

physogastric, i.e., in having its abdomen enlarged and the mem-

branous areas exposed. This condition is not very evident in the

type specimens due probably to excessive shrinkage during the

mounting of them on points. The California examples, received

in alcohol, exhibit the condition to a fairly marked degree. This

incipient physogastry is interesting in view of the fact that it is

such a common feature of termitophiles.

The long tibial bristles, the bisinuate pronotal margin, and

the relatively long legs are distinctive features of longipes. The

legs of the eastern species are on the average only about four-

fifths as long as those of longipes. The female abdominal char-

acters are, in general, similar to those of xenoflavipes, but the

dorsal bristles are short as in depressus.

The host of the type specimens could not be identified because

only the worker caste of Reticulitermes accompanies them. Since

Reticulitermes hesperus, the host of the California examples, is

not known to occur in the Utah desert region, it is doubtful if it

is their host. From available records, Reticulitermes tibialis

Banks seems to be only possibility.

Gentner seems to think may be new. A small series of this was

taken at Bear Springs, Wapinitia Cut-off.

Dr. Hatch listed 93 species and varieties recorded from the

state and ten species and two varieties probably occurring in the

state, giving a total 105 species and varieties which he estimated

probably represented 90 per cent of the Chrysomelidae of the

state. Five of the names in this list are among those noted by

Dr. Hatch as probably occurring in the state. Mr. Malkin has

added 10 more names to the list which, with the 20 new names

recorded here, brings the number of species and varieties occur-

ring in Oregon to 135, not including the three new genera noted.

I am inclined to think that this number does not represent more

than 80 per cent of the species and varieties of Oregon.

NOTES ON THE SYNONYMY, NYMPHS AND DISTRIBU-

TION OF HETEROPSYLLA TEXANA CRAWFORD

(Homoptera, Psyllidae)

BY D. D. JENSEN

Hawaii Agricultural Experiment Station, University of Hawaii

Synonymy

Van Dnzee (1923) described as Aphalara mera a species of

psyllid which had been collected in Lower California by the 1921

Expedition of the California Academy of Sciences to the Gulf of

California. Examination by the writer of specimens from this

series, in the collection of the California Academy of Sciences,

has revealed that the species involved is Heteropsylla texana

Crawford. This distinctive species, which is the genotype of

Heteropsylla , was described by Crawford (1914) from numer-

ous adults taken on eight different plant species in Texas, Ari-

zona, Colorado and Kansas. The specimens collected in Lower

California by Van Duzee show no differences in structure which

would permit their separation from H. texana.

Caldwell (1941) correctly inferred from Van Duzee’s descrip-

tion of Aphalara mera that the species could not be referred to

Aphalara because of the conspicuous pterostigma. Since he had

not had the opportunity of seeing Van Duzee’s specimens, he

placed mera tentatively in the genus Paurocephala which is

closely related to Heteropsylla.

On the basis of the facts discussed above, the names Aphalara

mera Van Duzee and Paurocephala mera (Van Duzee) must be

considered synonyms of Heteropsylla texana Crawford.

Nymphs

Except for a record by Klyver (1931) of two nymphs taken

on Prosopia glandulosa {=P. chilensis) , the literature contains

no information on the immature stages of texana. Collections

and observations made by the writer now permit the following

description of the nymph and of its feeding site on the host plant.

The body outline of texana nymphs is of the psylliine type as

defined by Ferris (1925). In this group the front wing pads

JilIJMSUJS HETISKO.E’S YLLA TJEXANA

project prominently from the contour of the body and are not

produced cephalad at the humeral angle. The last instar nymphs

are 2 mm. in length, naked, greenish to greenish-yellow in gen-

eral color. The antennae are long, reaching to the apex of the

wing pads, brown to black apically and on the distal portion of

each segment except the basal two. The dorsum is predominantly

membranous with the posterior portion of the abdomen, the wing

pads, and the head, except the median region, sclerotized. In

outline the abdomen is distinctive, being truncate apically and

sharply notched laterally at the base of the two dagger-like setae

produced on each side from the margin of the sclerotic area.

Four similar setae extend caudad from the truncate margin, one

from each postero-lateral angle and one on each side of the

median line midway to the postero-lateral angle. A second type

of setae, wedge-shaped and apically rounded, occurs on the body

margin as follows: three on each side of the proximal two-thirds

of the abdomen, one on the apical margin of each wing pad, one

on each side of the prothorax, and four on the cephalic margin

between the antennae. The circum-anal ring encompasses most of

the apex of the abdomen and is composed of a row of slit-like

pores.

The nymphs usually occur on the young tender growth where

they feed on the expanding leaves.

Distribution

Klyver (1931; 1932) extended the known distribution range

of texana to Nevada, Utah and New Mexico.

New Records

Adults of texana, collected by Van Duzee at Guayamas, So-

nora, Mexico, April 9, 1921, occur in the series labelled Apha-

lara mera in the collection of the California Academy of Sciences.

The Sonora record, however, was not published with Van Duzee’s

(1923) record from Lower California.

The following new collection records have been made by the

writer.* California. The species is herewith recorded from

California for the first time. All California collections were

It is probable that Prosopis chilensis (Molina) Stuntz is the

principal host, and possibly the only one, upon which texana

completes its entire life cycle. Other plants may serve as tem-

porary hosts for the adults. The indigenous range of Prosopis

chilensis includes southwestern United States, as far east as

Louisiana, Lower California, Mexico, Central America, Chile,

and the West Indies. The present known range of texana in-

cludes all of the southwestern states except Louisiana, Lower

California and Sonora, Mexico.

NOTES ON THE SPECIES OF PODABRUS OF OREGON

AND WASHINGTON

(Coleoptera, Cantharidae)

BY KENNETH M. FENDER

McMinnville, Oregon

A few records of Oregon and Washington Podabrus have been

cited by LeConte (1881), Fall (1928), Ralph Hopping (1929),

and the author (Fender, 1943) . They give no intimation of the

actual number of species found. The present report is based on

material in the collections of Dr. M. H. Hatch at the University

of Washington and of the author. Mr. M. C. Lane has kindly

given the author all of the Cantharidae he has collected.

Podabrus latimanus Motsch. Yamhill River south of McMinn-

ville, Oregon. Fall reports this species from “middle California.”

The male of P. latimanus has a lateral spine midway on the

front femora. This characteristic was mentioned by neither Le-

Conte nor Fall in their studies of the genus. Mr. C. A. Frost has

kindly confirmed the existence of such spines on the front

femora of LeConte’s male of the species.

Podabrus cascadensis Fender. Clackamas Lake, Clear Lake

and Hood River Meadows, Oregon. These are the only records

to date.

Podabrus comes LeConte. Throughout the region but it is

more common west of the Cascade Range.

Podabrus conspiratus Fall. Wash.: LaGrande (Lane), Man-

chester (Hatch), Green River, King County (Hatch), Seattle

(Hatch). Ore.: McMinnville, Boyer, Corvallis. Fall described

this species from Skagway, Alaska. No other records have been

found.

Podabrus pruinosus LeConte. The typical form of this species

is found occasionally throughout the northwest. The variety

diver sipes Fall is much more common than the typical form in

the area.

Podabrus falli Hopping. Wawawai, Wash. (Lane), Wallowa

Lake, Ore. This species was described from Otter Creek, B. C.,

West Bank, B. C. and Nine Mile, Princeton, B. C. This is a rather

variable species. The author has one specimen in which the pale

[VOL. XXI, NO. 2

bases and margins of the elytra are so extended as to almost

completely obliterate the black area.

Podabrus fulvus Fall. Black Snake Ridge, Blue Mts., Wash.

(Lane), Lewis Peak, Blue Mts., Wash., Mottet Meadows, Blue

Mts., Ore. Previously recorded by Fall from Kaweah, Calif, and

Atwell’s Mills, Tulare County, Calif.

Podabrus lanei Fender, new species

Male. Length 10-12 mm. Head black with muzzle yellow; an-

tennae black with the underside of the basal two segments pale

varying to a condition in which the basal segment is pale with the

other segments faintly annulated at the base. Pronotum yellow

with a black discal concavity; elytra and legs varying from yellow

to black. Head shining, sparsely finely punctate in front of the

antennae, coarsely closely punctate behind; eyes large; head wider

than thorax; antennae two-thirds the length of the body, the sec-

ond segment as long as the third. Pronotum transversely quad-

rate, the front angles rounded, the sides straight, converging

slightly to the hind angles which are prominent; surface shining,

finely sparsely punctate, more coarsely so anteriorly, convexities

moderate, median impressed line not eroded, extending from base

to apical third. Elytra shining, sparsely punctate basally, be-

coming finely rugose apically; vestiture cinereous, recumbent, fine

and rather sparse. Front tibiae and hind coxae not modified. All

claws armed with a broad acute tooth.

Female. Similar to male, eyes smaller, head just perceptibly

wider than thorax, antennae a little shorter.

Holotype male, Black Snake Ridge, Blue Mts., Wash., May

25, 1941, collected by M. C. Lane. Allotype female, Uniontown,

Wash., May 16, 1940, M. C. Lane. Paratypes : two males, same

data as holotype; three females, same data as allotype; one

male and one female, Uniontown, Wash., May 20, 1939, also

collected by Mr. Lane; one male, Wallowa Lake, Ore., June

22, 1941, K. M. and D. M. Fender; two males, three females,

Pine Creek, Baker, Ore., June 13, 1940, three males, Durkee,

Ore., June 17, 1941, collected by K. M. and D. M. Fender; one

male, two females, Rocky Bar, Idaho, collected by M. C. Lane,

and two females, Ashton, Idaho, June 15, 1939, collected by

M. C. Lane.

For my types I have chosen specimens that seem to be most

representative of the species. They have the antennae black with

the under side of the first segments pale; the elytra are a dingy

yellow and the legs black. In Fall’s key lanei would run to

APRIL, 1945 ]

FENDER rODADKUS

P. extricatus Fall or P. tejonicus LeC. and the dark form to

P. bolteri LeC. It differs from each of these species by its large

size, 10-12 mm. in lanei, 6-7 mm. in extricatus , 7.5 mm. in tejoni-

cus and 6.5 mm. in bolteri. In comparative lengths of the second

and third antennal segments it can also be separated: The seg-

ments equal in lanei ; the third segment twice as long as the

second in extricatus’, the third one-fourth longer than the second

in tejonicus-, the third distinctly longer than the second in bolteri.

Podabrus extricatus Fall. Baker Creek Valley, McMinnville,

Oregon. No previous records could be found other than those

of Mr. Fall in his description of the species. He cites Placer

and Plumas counties, California.

Podabrus scaber LeConte. Wallowa Lake, Oregon. Previously

reported from Oregon and Vancouver by LeConte, Stickine River,

B. C., by Wickham and Glacier Park, Montana, by Fall.

Podabrus macer LeConte. This species is apparently con-

fined to the Cascade Range in Oregon and Washington. Fall

knew it only from the middle California coast range.

Podabrus piniphilus Esch. The commonest species of this

region. It is very abundant west of the Cascades and quite

common to the east of them.

Podabrus extremus LeConte. Mt. Bonapart, Okanogan County,

Wash. (Lane). Previous records of this species are, Hudson

Bay; Labrador; Mt. Washington, New Hampshire; Banff, Al-

berta; Skagway, Alaska. My specimen, a male, keys out to

P. extremus but the sides of the pronotum are angularly sinuate,

whereas Fall noted them as being nearly straight and just per-

ceptibly convergent from the obliquely truncate front angles.

Fall’s specimens, however, were apparently all females. I place

this specimen tentatively in this species.

Podabrus bolteri LeConte. Bear Springs, Wapinitia Cut-off,

Oregon. LeConte’s unique type is from Lake Tahoe, California.

Fall concluded that the range of this species was the Sierras of

middle California.

Podabrus fissilis Fall. Dr. Hatch has a fine series of this

species from Paradise Park and Reflection Lake, Mt. Rainier,

Wash. P. fissilis has been recorded from Emerald Lake, B. C.,

and Skagway, Alaska, by Fall, and Hopping notes a long series

taken at Emerald Mine south of Prince Rupert. Hopping states

that an occasional female was nearly black. Several of Dr.

PAN-PACIFIC ENTOMOLOGIST

[VOL. XXI, NO. 2

Hatch’s specimens, both sexes, have the thorax entirely black,

the only pale area being the pale muzzle.

Podabrus instabilis LeConte. Blue Mts., Oregon. Cornucopia,

Oregon (Hatch), Green Springs Pass, Jackson County, Oregon

(Hatch), Lewis Peak, Blue Mts., Wash., Windemere, B. C.

(Hatch) . Fall gave the known range as the Sierras of California.

Podabrus danielsi Fender. (2 females) Berkeley Park, Mt.

Rainier, Wash. (Lane). These specimens agree nicely with my

female paratype. Females in this genus are often difficult to

place as many do not have the ungual characteristics used to

separate the males. Danielsi was described from Breitenbush

Lake, Mt. Hood National Forest, Oregon.

Podabrus cavicollis LeConte. Washington: Seattle (Hatch),

Olympia Hot Springs (Hatch), Quillayute (Hatch), Kirkland

(Hatch) and LaGrande (Lane). Oregon: Medford, McMinn-

ville, Boyer, Bear Springs, Blue Mts., and Devils Lake. Fall

cites Lake Tahoe, California, and Trinity, Plumas, Eldorado,

Sonoma counties, California, and Ormsby County in western

Nevada. Mr. Lane has kindly given the author three males of a

variety of cavicollis that has the elytra entirely black. They were

collected at LaGrande, Wash. For this variety I propose the

name of P. cavicollis var. hatchi, nov.

NOTES ON AMMOPLANUS

( Hymenoptera : Sphecidae: Pemphredonini)

BY V. S. L. PATE

Cornell University

A review of the Nearctic forms of the interesting thripotherous

genus Ammoplanus was presented recently. 1 At that time repre-

sentatives of only the typical subgenus and of Parammoplanus

Pate were known to occur in North America: Ammoplanellus

Gussakovsky was believed to be confined wholly to the Old World.

But in the material of Ammoplanus in the United States National

Museum, which I have been privileged to study through the cour-

tesy of Dr. E. A. Chapin, are representatives of two Nearctic

species of Ammoplanellus. Descriptions of these interesting nov-

elties are presented below, together with notes on some related

forms.

Subgenus ammoplanellus Gussakovsky

Ammoplanus ( Ammoplanellus ) Gussakovsky, Bol. Soc. Espan.

Hist. Nat. XXXI, p. 442, (1931). Pate, Bull. So. Calif. Acad.

Sci., XLI, p. 144, (1943).

Genotype: Ammoplanus ( Ammoplanellus ) chorasmius Gus-

sakovsky, 1931. (Monobasic and by original designation.)

The subgenus Ammoplanellus differs from both Parammo-

planus and the nominate complex by the female lacking a dis-

tinct pygidial area on the ultimate abdominal tergite and by the

males having the terminal abdominal sternites simple and un-

modified. Additionally, the fore wing of Ammoplanellus has the

costa absent distad of the stigma and the radial vein does not

attain the costal margin, thus leaving the marginal cell broadly

open anteriorly. In this respect the present group resembles

Parammoplanus. But in Ammoplanellus the hind tibiae are dis-

tinctly bowed or curved in lateral aspect; the pronotal tubercles

[VOL. XXI, NO. 3

are eburneous; the dorsal face of the propodeum is alveolate to

areolate; the occipital carina is very well developed and almost

a complete circle in extent; the genapontal region of the head

is elongate, generally about twice as long as the depth of the

oral fossa ; and the clypeus is entire and truncate medio-

apically. Conversely, in Par ammoplanus, as well as in Ammo-

planus in the restricted sense, the hind tibiae are relatively

straight; the pronotal tubercles are black or at least concolorous

with the remainder of the pronotum; the dorsal face of the pro-

podeum is granular, striate, or aciculate, and usually bisected by

a carinule; the occipital carinule is generally shorter and seldom

more than a semi-circle in extent; while the genapontal region is

relatively short, usually not more than one and a half times the

depth of the oral fossa; and the clypeus is diversely excised

medio-apically.

Ethology. The species of Ammoplanellus probably nest in

pre-existing holes or crannies and provision their burrows with

thrips as do the forms of the nominate subgenus . 2 Associated

with the specimens studied of the following Arizonan form xila

is a minute Chrysid wasp . 3 From the data now at hand, this

Chrysid may prove to be a parasite of Ammoplanus xila, and, if

so, this will be the first record of any such association in the

genus Ammoplanus.

Component Species. The subgenus Ammoplanellus at present

comprehends one Palaearctic species, the Transcaspian choras-

mius Gussakovsky; three Ethiopian forms, the Southern Rho-

desian species consohrinus Arnold and rhodesianus Arnold, and

the Malagasy madecassus Kohl ; and the following two new

western North American species: umatilla and xila.

Ammoplanus (Ammoplanellus) umatilla 4 Pate, new species

(Fig. 3)

The immaculate clypeus, the more coarsely sculptured pro-

notum and mesonotum, and the alveolate dorsal face of the pro-

podeum, readily distinguish umatilla from the following Ari-

zonan form xila.

V. et.: Maneval : Ann. Soc. Ent. France, CVIII, pp. 78-81 (1939).

3 This Chrysid represents a new genus and species and is apparently somewhat

intermediate between the conventional subfamilies Elampinae and Chrysidinae. I

have forborne describing it inasmuch as the unique specimen before me is not in

a very good state of preservation.

Biological Notes. Dr. C. F. W. Muesebeck of the Bureau of

Entomology and Plant Quarantine has very kindly supplied me

with the information that Mr. R. A. Flock of the Office of State

Entomologist, Arizona Commission of Agriculture and Horticul-

ture, observed many specimens of Ammoplanus xila and a small

( undescribed) Chrysid wasp flying rapidly about holes in a chair

from which had previously emerged small powder-post flat-

headed borers ( Hesperorhipis mirabilis Knull). Though the

Chrysids are not definitely known to have been reared, it is as-

sumed, perhaps without warrant, that they are social parasites of

Ammoplanus xila. And if this is so, it will be the first such asso-

ciation of a Chrysid wasp with any member of the Ammoplanoid

complex. From what is already known of the biology of Ammo-

planus, the species do not construct burrows but merely utilize

pre-existing cracks, crannies or holes for their nests. In all prob-

ability, xila in this instance occupied the abandoned borings of

the small Buprestid Hesperorhipis mirabilis.

PATE— AMMOPLANUS

Giner Mari has erected the subgenus Ceballosia for those forms

hitherto referred to Ammoplanus (s. str.) in which the males

have the hind metatarsi more or less modified — usually expanded

into a median tooth or lobe — whilst the females have the clypeus

armed medially with a large robust median tooth or apophysis.

However, a re-examination of the Nearctic species, as well as a

series of several still undescribed Algerian Ammoplanus in my

cabinet, fails to substantiate Giner Mari’s belief that these forms

merit recognition as a discrete subgenus. Furthermore, the fea-

tures upon which Giner Mari has chosen to base his Ceballosia

are now generally recognized to exhibit extreme variations in

individual species. This has been very ably demonstrated by De

Beaumont in a recent paper on heterogenic growth in a number

of aculeate Hymenoptera. 7 Consequently in view of all this, I

believe that Ceballosia must be regarded as merely a synonym of

Ammoplanus in the restricted sense, although the component

Palaearctic forms ( rjabovi Guss., platytarsus Guss., diver sipes

Guss., metatar salis Guss., sibiricus Guss., insularis Giner Mari,

ceballosi Giner Mari, and marathroicus DeStef.) undoubtedly

constitute one or more discrete species groups within the nomi-

nate subgenus.

LONGEVITY OF FIFTH INSTAR LARVAE OF HORNIA

BOHARTI LINSLEY

In April, 1941, a large number of fifth instar larvae of Hornia

boharti Linsley were collected in Grapevine Canyon, ten miles

south of Little Lake, Inyo County, California 1 . Unlike the other

known members of the genus, this species normally exhibits a two

year life cycle, supposedly as a protective device useful in resisting

the extreme dryness of its habitat and occasional poor flower

years. Since all larval feeding takes place in the first four instars,

these larvae had not fed since the summer of 1939 or 1940. They

were stored in humidity chambers and during late spring and

early summer, 1942, the majority transformed into sixth instar

larvae, followed by pupation and adult emergence. At this time

it was noticed that several dozen fifth instar larvae had undergone

no further development but nevertheless appeared to be alive.

These were subsequently kept at room temperatures and relative

humidities and several adults emerged both in 1943 and 1944.

These mated normally and laid large quantities of viable eggs.

In June, 1945, the last three adults emerged and the single male

mated with one of the two females. She subsequently deposited

viable eggs. These three specimens appeared normal in every

respect except for a distinct reduction in size. Similar small adults

are occasionally encountered in the field and may also result from

prolongation of the period spent as fifth instar larvae. In the

present case the last adults transformed from larvae which had

not fed for at least five and possibly six years. — E. G. Linsley and

SCHUSTER— CHYPHOTES

A NEW SPECIES OF CHYPHOTES FROM CALIFORNIA

(Hymenoptera, Mutillidae)

BY R. M. SCHUSTER

Cornell University, Ithaca, New York

In a collection of Mutillidae in the American Museum of

Natural History there was found the following female of

Chyphotes, representing a very distinct new species.

This species is the only one in the genus that has the entire

head and thorax blackish in color, sharply contrasted from the

bright orange abdomen. In the Monograph of the Genus

Chyphotes of North America (Buzicky, Entomologica Ameri-

cana, vol. 21, 1941, pp. 201-250) Buzicky gives a key to the

females. The following species goes to couplet 7 in his key, and

the key can be changed as follows in order to allow for its

recognition :

7a. Head, thorax and legs entirely infuscated to black in color,

the abdomen orange; third abdominal tergite concolorous

with rest of abdomen; sculpture of abdomen very weak.

bicolor Schuster

-. Head and thorax concolorous with the abdomen; if the legs are

at all infuscated, the third abdominal tergite is also dark-

ened, and the sculpture of the abdomen is rather coarse 7

This species appears to be closely related to testaceipes Fox

and auripilus Buzicky, both of which have the head and thorax

concolorous with the abdomen, however. It appears to be most

closely related to the latter, from which it does not differ mor-

phologically to any marked degree; however, Buzicky states that

the head has the “punctures shallow but contiguous,” whereas

they are rather deep in the present species, and contiguous only

on the lower frons.

Chyphotes bicolor Schuster, new species

Female. Length 8.2 mm. Head and alitrunk deeply infuscated

and piceous to nearly black, the legs and antennae scarcely lighter

(more or less mahogany colored), much darker than the orange

abdomen. Notum of head, thorax and abdomen, with the exception

of the apical three tergites and the propodeum, which are silvery

[VOL. XXI, NO. 3

erect pubescent, entirely erect and appressed golden-yellow pubes-

cent.

Head very closely to subconfluently punctured on the lower

frons, the punctures more or less polygonal-rounded, those of the

rest of the head distinctly separated, rounded, with polished inter-

vals (those of the antennal scrobes considerably smaller than those

of the rest of the head). Scape with coarse, scattered, well-

separated foveate punctures, with wide polished intervals, with

sparse, decumbent silvery and yellowish-golden hairs; pedicel

slightly less than half as long as the first flagellar segment, which

in its turn, is very slightly longer than the second (the ratio be-

tween the two, dorsally measured, 41:38). Mandibles, clypeus and

genae with very sparse silvery, pilose hairs, the frons and vertex

with a nearly circular cap of decumbent, appressed to erect light

golden pubescence. Eyes subovate-subreniform, posteriorly angu-

late in outline, about one-sixth longer than high.

Thorax nearly black, with rather sparse, erect, very long, light

golden pubescence dorsally; densely but not confluently punctured,

similarly to vertex, the intervals polished. Mesopleurae punctate

all over, the punctures of the anterior margin sparser, smaller and

scattered, however. Mesosternta each with a short, subdentiform

or carinate lobe or process between and close to the mesocoxae.

Inner edges of the metasternal teeth with the sinus v-shaped, sides

at somewhat less than 90 degrees to each other. Pro-podeum simi-

larly punctured to the rest of the thorax laterally; the apical

median area somewhat depressed and transversely wrinkled, while

the median area immediately anterior is obscurely, rugosely

sculptured.

Abdomen with the anterior part of the first sternite terete,

glabrous, polished, not covered by tergite one, slightly widened to

apex; meeting tergite one at a right angle or, if anything, lat a

slightly obtuse angle. Entire abdomen a bright golden orange,

dorsally weakly, moderately closely punctured (the sculpture not

more than half as coarse as in elevatus). Second sternite laterally

coarsely punctured, medially (ie., on disk) with the punctures

fine, scattered, nearly obsolete in part, the disk thus more or less

polished. Felt line of second tergite short, about a fifth the length

of the tergite. Vestiture of abdomen of silvery erect, long pilose

hairs below; that of the notum similar, but bright golden, except

for that of the apical two or three segments, where it is largely

or entirely silvery.

Legs deeply infuscated, silvery pubescent.

ALEXANDER— WESTERN TIPULIDAE

UNDESCRIBED SPECIES OF TIPULIDAE FROM THE

WESTERN UNITED STATES

(Diptera)

PART II

BY CHARLES P. ALEXANDER

Massachusetts State College, Amherst

The preceding part under this title was published in the Pan-

Pacific Entomologist, 20:91-97; 1944. Most of the species- de-

scribed at this time are from the extensive Melander Collection,

and were taken in Washington and northern Idaho by Dr. Melan-

der. I wish to express my deep thanks to Dr. Melander for per-

mitting me to retain the types of those species that were based

on single specimens. All of the species discussed herewith belong

to the single tribe Hexatomini, extensively developed in our

western states.

Dactylolabis imitata Alexander, new species

Male. Length about 10 mm.; wing 10 mm.

Generally similar to damula and pteropoecila, differing con-

spicuously in the details of wing pattern and the venation.

Wings with the ground whitish sub hyaline, the prearcular and

costal cells clearer yellow; a heavy brown pattern, as follows:

Postarcular, in bases of cells R and M, more extensive in the

former; a major area at origin of Rs, continued across cells R

and M to vein Cu, vaguely broken by a pale seam in cell R adjoin-

ing vein M; a relatively narrow but complete crossband at the

cord; other major darkenings at R i +2 and R 2 , the outer end of cell

1st Mi and the fork of M i +2 ; a narrow, continuous brown seam

along vein Cu, chiefly in cell Cu% and immediately behind vein Cu»;

a similarly narrow seam along vein 2nd A ; veins brownish yellow,

darker in the patterned areas. Venation: Sc long, both Sci and

Sci ending beyond the fork of R 2 + 3 + 4 , the latter very short, subequal

to or shorter than the basal section of Rs ; cell 1st Mi large, m and

the basal section of M 3 subequal in length; m-cu more than three-

fourths its own length beyond the fork of M.

The most similar described species is Dactylolabis pteropoe-

cila (Alexander) which has the wing pattern almost the same

but much more restricted, and which differs in important vena-

tional details, as the longer R 2+ 3+ 4 , the lengthened cell 1st M 2 ,

and the unusually long m. D. damula (Osten Sacken) is more

Limnophila ( Prionolabis ) gruiformis is well-distinguished

from other similar regional species by the structure of the male

hypopygium, particularly the tergite, both dististyles and the

MaoSWAIN— cymatodeba ovipennis

Habitat. Washington (Pacific County).

Holotype. $ , Ilwaco, June 28, 1925 (Melander) .

The reference of this curious fly to Shannonomyia Alexander

must be held to be somewhat provisional but on the basis of

the short subcosta and the loss of cell M 1 , it agrees more closely

than with Limnophila. The one discordant venational feature is

the long Rs which is much longer than in the other described

Nearctic species. The discovery of the male sex may result in

assigning the species elsewhere. The fly is readily told from all

other regional species of Hexatomini by the white tarsi, in con-

junction with the loss of cell M 1 of the wings.

NOTES ON THE HABITS OF THE PREDATOR CYMATO-

DERA OVIPENNIS SAY WITH A DESCRIPTION

OF THE PUPA

( Coleoptera, Cleridae)

BY J. W. Macs WAIN

University of California, Berkeley

During a study of the aculeate Hymenoptera using the living

and dead branches of Sambucus for nesting purposes, two beetle

larvae were found that proved to be Cymatodera ovipennis Say. 1

Blaisdell (1892) has recorded larvae of this species from bur-

rows of the cerambycid Ipochus fasciatus in southern California.

A summary of the food habits of this species by Boving and

Champlain (1920) states that it is “a predator on Lepidopterous

larvae infesting cones of Pinus jeffreyi-, reared from cones of

Pinus ponderosa and Pseudotsuga taxifolia; from Pinon pine

infested with Carphoborous and Callidium.” These records on

secondary woodboring Coleoptera are similar to those given by

the same authors for Cymatodera undulata Say, which was sub-

sequently reared by W. V. Balduf (1926) from the bur oak galls

made by the cynipid, Disholcaspis mamma Walsh. This paper is

designed to increase the knowledge of the biology of this species

and to illustrate and describe the pupa.

Larva

An excellent description of the mature larva has been given

by Boving and Champlain. It will suffice to add that, following

ecdysis and in earlier instars, the general body color of the larva

is pale rose and the pigmented portions a pinkish violet. In the

ultimate and penultimate larvae, the membraneous portions of

the thorax and abdomen have a distinct greenish color which in

Boving and Champlain was described as clay yellow. This dis-

crepancy is undoubtedly due to the fact that their description was

based on larvae which had been preserved in alcohol.

Pupa (fig. 1)

Head with four spines forming a single row on upper portion

of face. Pronotum with a row of ten stamineous spines along

anterior margin, five spines along each margin, a series of seven

spines just anterior to the mid-line with the two on each side of

the center caudad to the rest of the series, an inverted triangle

of three spines in the posterior half. Legs with an anterior

femoral spine three-fourths of the distance from the base to the

apex, each pair also with a spine on the posterior margin of the

femur, the intermediate pair of legs with a second adjacent

spine. Abdomen with a small group of median lateral spines, a

single pair of spines on the posterior margin of each tergite and

one on each side of the mid-dorsal line, each pair increasing in

length from anterior to posterior.

When first formed, color entirely white, head folded under the

prothorax. After seventh day, eyes light brown, head and notum

evenly flecked with irregular purple spots, dorsal and lateral

margins of abdomen heavily pigmented with purple with the ex-

ception of a thin mid-dorsal line which is green, ninth abdominal

segment and caudal appendages white. Mandibles, labial palpi,

maxillae, maxillary palpi, clypeus, antennae, legs and wings all

white until fifteenth day. First brown pigmentation of tips of

mandibles on fifteenth day following pupation, tarsal claws

pigmented on eighteenth day, mouth parts and all appendages

becoming increasingly suffused with brown from twentieth to

twenty-fifth day. Emergence on twenty-fifth day.

Judging from the pupal description given by Balduf for

Cymatodera undulata Say, the spine pattern may prove to be the

easiest method of separating pupae of this genus.

MACSWAIN— CYMATODERA OVIPENNIS

Cymatodera ovipennis has been found at elevations of several

hundred to seven thousand feet throughout Western North Amer-

ica. The adults are nocturnal and are most frequently taken in

light traps or at light during the summer months.

The first two specimens which were encountered in this study

were collected in the dead branches of Sambucus at Mineralking,

Tulare County, California, August 10, 1939, by G. E. Bohart.

Fig. 1. Pupa of Cymatodera ovipennis LeConte, X6%.

Two larvae were obtained from a total of over three hundred

twigs, which were being used by numerous aculeate Hymen-

optera for nesting purposes. One had fed on a cell series of

Hoplitis ( Alcidamia ) sp. and then constructed a resting cell in

the pith of the twig to one side of the bees burrow. This larva

was placed in a large shell vial with a cork stopper. Within a

few days the larva had cut a small circular hole in the cork and

hollowed out a pupal cavity. This cell was constructed so as to

leave only a very thin, almost membranous, shell of cork separ-

ating it from the external environment. Similar behavior was

reported by Linsley and MacSwain (1943) for Trichodes ornatus.

The cork was later split open and reinserted in the vial to allow

frequent observations. On each examination the larva became

100

PAN-PACIFIC ENTOMOLOGIST

[VOL. XXI, NO. 3

active but no change was observed for almost two years. Pupa-

tion finally occurred on July 9, 1941, and the adult emerged on

August 8, 1941. The second larva was found in a twig containing

the remnants of a cell series of Osmia sp. This larva was pro-

vided with a similar environment, but pupation had not occurred

by August, 1941, although a larval skin was shed on March 18,

1941. This specimen was killed and preserved for future study.

Other specimens were obtained as follows: one dead adult and

larval skins from a dead branch of Sambucus containing de-

stroyed cells of Osmia sp. at Mt. Diablo, Contra Costa County,

California, on July 10, 1940, two larvae (one immature) and

one pupa in the dead branches of Sambucus containing old cell

series of Ceratina acantha submaritima (Ckll.) at Kyburz, El

Dorado County, California, July 26, 1941, and one dead larva

in Sambucus containing old series of Osmia sp. at Mt. Rose,

Washoe County, Nevada, July 27, 1941.

The normal duration of the life cycle of this species remains

a matter for conjecture, but from the material at hand, it would

seem likely that it involves one or more years, with larval feed-

ing confined to the first year. All attempts to feed larvae after

they had constructed their resting cells were unsuccessful.

VAN DYKE— COLEOPTERA

101

NEW SPECIES OF NORTH AMERICAN COLEOPTERA

BY EDWIN C. VAN DYKE

California Academy of Sciences, San Francisco

Carabidae

Trechus humboldti Van Dyke, new species

Rather small, robust yet gracefully formed, rufopiceous with

antennae, legs and ventral surface rufous. Head broadly elevated

at middle, bounded laterally by deep arcuate sulci, the occiput

smooth or very minutely rugose posteriorly, the eyes moderately

prominent, and antennae somewhat moniliform and reaching be-

hind base of prothorax. Prothorax about as broad as long, cordi-

form, apex emarginate, sides arcuate in front, sinuate behind with

hind angles right angled, margin rather broad, reflexed and wider

behind, disk convex, smooth and shining, with deep median longi-

tudinal groove extending from anterior transverse impression to

base, and with a broad and deep impression within each hind angle.

Elytra oval, about twice as wide as prothorax, moderately convex,

with seven striae, the four inner ones deeply impressed, complete

and distinctly punctured, the outer ones feebler, and two small

foveae on third striae, one near base, the other at middle. Beneath

smooth and shining. Length 4.5 mm., breadth 2 mm.

Holotype (No. 5434, Mus. Calif. Acad. Sci., Ent.), a unique

male, collected by myself in the dense redwood region near

Orick, Humboldt County, California, July 5, 1931.

This very graceful species probably belongs to the group with

ovipennis but it differs from it and its relatives by having a

longer and cordiform prothorax, quite transverse in ovipennis ,

the elytra more distinctly oval, quite elliptical in most ovipennis,

and very distinctly and deeply striate on the disk. Though most

specimens of ovipennis have been collected in the San Francisco

Bay region, it does extend along the coast as far north as British

Columbia and of course is to be found in Humboldt County.

Specimens of a phase of Trechus chalyhaeus Mann., a more

northern species, have also been collected only a short distance

north of Orick, at Crescent City.

Badi&ter mexicanus Van Dyke, new species

Moderate in size, black, antennae, legs and mouth parts testa-

ceous; narrow side margin of prothorax and elytra, as well as

epipleurae somewhat rufous, head and pronotum alutaceous and

somewhat dull, the elytra shining and irridescent. Head with eyes

quite prominent, the antennae reaching three segments beyond

hind margin of prothorax. Prothorax about twice as wide as long,

almost one-fourth broader than head, apex emarginate, sides arcu-

ate in front, straight and converging behind, the hind angles ob-

tuse, feebly rounded, the lateral margin narrow and slightly re-

flexed; the disk with median longitudinal line deeply impressed,

the anterior transverse impression quite evident and the posterior

impressions extensive. Elytra about one-fourth longer than broad,

a third broader than prothorax, base emarginate, sides almost

straight and feebly divergent to posterior fourth, thence gradually

rounded to apex; the disk feebly convex, all striae complete and

well impressed, the intervals flat, second striae with two vague

foveae and the marginal striae with numerous punctures. Beneath

smooth and shining. Length 5.5 mm., breadth 2.75 mm.

Holotype female (No. 5435, Mus. Calif. Acad. Sci., Ent.) a

unique specimen collected at Oaxaca, Mexico, July 20, 1937,

and received from the collector, M. A. Embury.

This species, the first of the genus to be found in Mexico,

would appear to be most closely related to our well-known

micans Lee. It differs from the latter by being more robust, pro-

portionally broader, with the elytra less parallel-sided, the an-

tennae not at all piceous, the lateral lighter colored margins of

both prothorax and elytra narrower and the elytral striae more

deeply impressed.

Monotomidae

Hesperobaenus fenyesi Van Dyke, new species

Elongate, subdepressed, rufous, antennae and legs lighter in

color, the entire upper surface alutaceous. Head flattened above,

rather coarsely, closely punctured, eyes moderately prominent,

with sides behind eyes parallel to posterior constriction. Pro-

thorax slightly longer than broad, disk feebly convex, the coarse

punctures approximately their own width apart, sides straight or

very feebly arcuate and convergent to base, with margin crenu-

lated, the base finely margined. Elytra over twice as long as

broad, about one-fourth longer than forebody and perceptibly

broader, striae finely, sharply impressed and rather finely punc-

tured, the punctures their own width apart in general and with

short recumbent setae arising from them, the intervals broad and

flat. Beneath rather finely, sparsely punctured in front and be-

hind more coarsely punctured on the metapleurae. Length 2.75

mm., breadth 1 mm.

Holotype (No. 5436, Mus. Calif. Acad. Sci., Ent.) and seven

paratypes from Pasadena, California, six collected in March

and two in July, by Dr. Adalbert Fenyes. Besides these specimens

in the Fenyes collection, we have in the Academy collection,

three from Sierra Madre, Los Angeles County, February 17,

1909, in the Van Dyke collection, one from Poway, San Diego

County, in the Blaisdell collection, and one from the Placer

Ranger Station, Madera County, collected on Alnus rhombi-

folio by E. F. Wohletz.

This species superficially resembles Hesperobaenus rufipes Lee.

from the eastern part of the country. It differs by being in gen-

eral a bit smaller, by having the sides of the head back of the

eyes parallel, not prominently angulated, the prothorax evidently

longer than broad, with sides less parallel, and the elytra more

finely striato-punctate. It seems to be dominantly a southern

California species that has apparently been overlooked. Our

other species in the genus are all more or less bicolored like the

common Pacific Coast abbreviatus Mots.

Melasidae

Hylus (Hypocoelus) arizonicus Van Dyke, new species

Robust, somewhat elongate, subparallel; coal black, subopaque,

apex of last antennal segments and tarsi rufous, the upper sur-

face clothed with a rather sparse, very short, closely appressed

pile, only evident on good magnification. Head convex, with a

slight transverse impression forwards, sulcate between the eyes,

clypeus narrowed at base and transversely impressed at middle,

the entire head finely, densely, umbilicately punctured and aluta-

ceous; antennae about reaching hind angles of prothorax, rather

robust, second segment small, third long, about one and a half

times as long as broad, segments 4-6 short and transverse, 7-8

somewhat broader, and 9-11 considerably broader and longer,

forming an elongate club, the tenth the shortest and the eleventh

acute at apex; the eyes moderately prominent. Prothorax slightly

broader than long, apex transverse, sides straight and parallel

behind, arcuate from middle and gradually convergent towards

apex, base bisinuate and hind angles acute, prominent and ex-

tending backwards; the disk convex, with a well impressed median

longitudinal line, the surface rather finely, densely umbilicately

punctured and alutaceous, the base with a definite margin. Elytra

104

with striae well impressed, the strial punctures more or less vague,

the intervals feebly convex and finely rugose. Beneath densely

punctured, more coarsely in front and more finely behind and alu-

taceous. Hind coxal plates triangular. Length 7 mm., breadth

2.5 mm.

Holotype, presumably a male (No. 5437, Mus. Calif. Acad.

Sci., Ent.) a unique collected by myself high up in the Chirica-

hua Mountains, Arizona, July 16, 1942.

This very distinct species is one of our larger species, but

little smaller than the recently described robustus Van Dyke. It

may be readily distinguished from all of our species by its size,

its coal black color, and rather short antennae which have the

three terminal segments gradually though definitely enlarged so

as to form an elongate club.

Buprestidae

Acmaeodera lagunae Van Dyke, new species

Robust, cuneiform, moderately flattened, aeneous, the elytra

generally with a more greenish lustre than the forebody though

often the reverse, upper surface moderately clothed with rather

long, erect, dark pile, the under surface with a sparser, more de-

pressed, gray pile; the pronotum immaculate, the elytra with vari-

able markings though the general pattern is as follows : the third

and fifth intervals spotted with yellow at base, the third usually

with a few adidtional scattered spots, the lateral interval yellow

for at least its basal third but the marking not quite reaching the

basal margin, and from three to four conspicuous transverse ma-

culations, the largest at the middle, irregular, and extending in-

wards to about the fifth interval, a narrower one, one-half the

distance between this and apex, and one to two smaller, often in-

terrupted maculations between this latter and apex. Head coarsely,

densely punctured, longitudinally impressed at middle; antennae

extending beyond middle of prothorax, segments 5-11 moderately

serrate. Prothorax somewhat more than twice as broad as long,

expanded at the posterior third where broader than elytra; the

disk coarsely punctured, the punctures well separated at center,

approximate laterally, a broad, somewhat triangular, longitudinal

impression at center and moderately well impressed foveae between

this and basal angles, the lateral margin well developed, com-

pletely, feebly reflexed, yet because of incurving not seen near

base when viewed from above. Elytra moderately flattened, striae

only distinctly impressed at sides and towards apex, strial punc-

tures coarse and closely placed at sides, much finer and better

spaced near suture, the intervals on disk flat and with a few fine,

scattered punctures, the third and fifth often elevated near base,

the humeral umbone also prominent, the lateral intervals generally

quite convex especially posteriorly. Beneath, but moderately, rather

sparsely punctured in front, more coarsely and densely on posterior

ventral segments. Pro sternum feebly retracted and bisinuate at

apex, last ventral with distinct, transverse plate near apex. Length,

type, 10 mm., breadth 4 mm., length in series varies from 7 mm.-

11 mm. and breadth from 2.5 mm-4 mm.

Holotype (No. 5438, Mus. Calif. Acad. Sci., Ent.) and nu-

merous designated paratypes from a series of sixty-five specimens,

collected by E. S. Ross and G. Bohart, at La Laguna, Sierra

Laguna, Lower California, October 14, 1941.

This species is undoubtedly related to Acmaeodera scapularis

Horn and the larger specimens closely simulate it, and both are

confined to the Cape Region of Lower California. Acmaeodera

lagunae differs from scapularis by being proportionally less

broad in front, by having the prothoracic margin complete and

by never having a yellow spot near its base, by having the pro-

notal impressions far less pronounced, the fifth elytral interval

never carinate as it is in scapularis and the strial punctures never

as coarse near the suture as they are in the other, where all strial

punctures are quite similar, very coarse and approximate. The

color pattern is quite similar but the median bar is generally very

broad in scapularis. The color pattern of Acmaeodera flavostica

Horn is even closer but this species is proportionally shorter and

belongs in another group.

Acmaeodera transversa Van Dyke, new species

Elongate, subcylindrical, of moderate size, black, elytra feebly

bronzed, pronotum immaculate; elytra with a short, transverse

yellow bar near base extending from second to sixth interval, a

narrow transverse yellow bar extending from the second to eighth

interval situated at the middle, a narrow oblique yellow bar ex-

tending from the third to sixth interval, midway between pre-

ceding and apex, a short transverse spot, also yellow, extending

from second to fourth interval, a short distance in front of apex,

a small elongate yellow spot behind the humeral umbone and a

bright red spot of fair size at the outer extremity of the oblique

bar which extends outwardly from the eighth to the eleventh or

marginal interval. Head with well spaced, rather coarse punc-

tures, a feeble longitudinal impression at middle, antennae short,

barely reaching middle of pro thorax, segments 5-11 serrate, and

with short, sparse, semierect gray pile. Prothorax one-third broader

than long, a little narrower than base of elytra, apex feebly bi-

emarginate, sides moderately arcuate, gradually narrowing from

106 PAN-PACIFIC ENTOMOLOGIST [ V0 L. XXI? N0 . 3

base to apex, the lateral margin narrow, not readily visible when

viewed from above because of the bulging sides of pronotum and

dense pile placed along the sides, the disk convex, rather coarsely

and densely punctuated medially, with a sparse, semierect pile

above and a patch of dense, white pile along the lateral margin.

Elytra twice as long as broad, sides sinuate before the middle, and

gradually narrowed posteriorly to blunt apex; the disk feebly con-

vex, humeral umbone moderately prominent, the striae well im-

pressed and rather coarsely, densely punctured in front and more

finely punctured behind as well as confined to the striae; the in-

tervals towards suture flattened, and convex towards sides and

with a single row of fine punctures, from which arise very short

gray setae, most evident apically. Beneath moderately coarsely,

densely punctured on prosternum, very coarsely punctured on

propleurae, more finely on abdomen, sparsely in front and densely

behind, the apical segment with a short, transverse plate in front

of apex, the center of all abdominal segments quite smooth and

naked while the sides are clothed with a dense, silky, white pile

as are also the meso and metapleurae. Prosternum at apex, feebly

retracted, the center emarginate and with a prominent tooth on

each side of the emargination. Length 8 mm., breadth 3 mm.

Holotype (No. 5439, Mus. Calif. Acad. Sci., Ent. ), a unique

collected at Las Animas, Sierra Laguna, Lower California,

October 12, 1941, by E. S. Ross and G. Bohart.

This very distinct, quadribalteate species probably belongs in

the second or sinuate series of the Acmaeodera. It, however,

stands more or less apart, its black or feebly metallic color, sub-

cylindrical form, short, sparse elytral setae, and dense white

pubescence at the sides of the ventral segments as well as the

brilliant red spot at the sides of the elytra posteriorly, giving it

a distinctive appearance.

Acmaeodera nautica Van Dyke, new species

Moderately elongate, somewhat flattened and cuneate; a bright

blue above, the elytra ornamented with yellow as follows: a yellow

line on the marginal interval just back of the humerus, a broad

spot extending from the sixth interval to margin, at middle, a nar-

row transverse bar extending from the fourth interval to margin,

half way between middle and apex, and two small marginal spots,

one very small, in front of the last and another, somewhat larger

near apex; the upper surface sparsely clothed with dark, erect

pile, the under surface with much sparser, somewhat inclined gray

pile. Head rather coarsely, densely punctured, feebly longitudi-

nally impressed at middle; antennae reaching middle of prothorax,

segments 5-11 serrate. Prothorax over twice as broad as long,

slightly expanded in front of base where somewhat broader than

elytra, apex feebly biemarginate, sides subangulate, almost parallel

behind, straight and convergent in front, the margin distinct,

slightly reflexed, complete and readily seen from above; the disk

coarsely, cribately punctured at sides, less coarsely and densely

medially, the median longitudinal impression well marked, the

basal impressions small, foveiform, and distant from the hind

angles. Elytra about twice as long as broad, sides feebly sinuate

in front of middle, and feebly arcuate and gradually narrowed to

blunt apex; the disk somewhat flattened with a moderate depres-

sion at base near suture, the humeral umbones distinct, the striae

finely, sharply impressed at middle and finely, rather closely punc-

tured, more broadly and deeply impressed at sides and with the

punctures coarser, the intervals medially flattened and with a row

of fine, well spaced punctures along their middle, the intervals at

the sides quite convex. Beneath, a bluish black color, coarsely,

rather densely punctured in front, very finely and sparsely on the

abdomen. Pro sternum feebly retracted in front, the shallow median

emargination without marginal teeth. The last ventral segment

without evident ventral plate near apex. Length 11 mm., breadth

4 mm.

Holotype (No. 5440, Mus. Calif. Acad. Sci., Ent.), a unique

collected near Lafayette, Contra Costa County, California,

September 3, 1943, and submitted by Dr. E. G. Linsley.

This attractive species, because of its bright blue color, at first

sight suggests mariposa Horn, but because of its shape and color

pattern appears to approach more closely to prorsa Fall. The

yellow maculations are of similar size and similarly placed. The

species differs, though, from prorsa not only by being blue in-

stead of bronze, but by being proportionally a bit shorter, with

the prothorax less widely expanded, and the punctuation of the

median areas of both pronotum and elytra far less coarse and

dense.

Agaeocera gentilis peninsularis Van Dyke, new subspecies

This subspecies agrees with typical gentilis in regard to most

fundamental characters but differs by being a little bit more

robust and proportionally broader, of a dark bronze or cupreous

color, both above and beneath, not a bright green as in gentilis,

by having the head and pronotum more distinctly alutaceous and

much more coarsely punctured and rugose, and the elytral intervals

quite distinctly elevated and carinate towards suture and apex.

Most records that I have seen for typical gentilis, give west-

ern and southwestern Texas as its habitat. Sharp in the “Biologia

Centrali-Americana,” gives Coahuila and Villa Lerdo in Durango,

Mexico. In the collection of the California Academy of Sciences,

besides twelve Texas specimens, mostly from near El Paso, we

have one from Grant County, N. Mexico (Coll, by R. T. Kellogg),

and Mexican specimens from Lerdo (Fenyes Coll.) Torreon and

Villa Juarez (Coll, by M. A. Embury). Near El Paso, I collected

several specimens on a species of mallow. I know of no specimens

from Arizona or the west coast of Mexico, though the very dis-

tinct Agaeocera scintillans Water, is found in southern Arizona,

Sabino Canyon, as well as on the west coast of Mexico, the states

of Sonora and Sinoloa, thus apparently wedging in between the

two phases of gentilis. In time we may find that the two are in

reality, geographically separated. In that case, we would be justi-

fied in elevating peninsualris to specific standing, but until we get

more material, I feel that it is best to keep them as phases of the

same species.

Since my review of the Buprestidae of Lower California (Pro-

ceed. Calif. Acad. Sc., Vol. 24, pp. 97-132, 1942), a second expe-

dition has been made to that region by Dr. E. S. Ross, this time

accompanied by George Bohart. This expedition besides securing

the two new Acmaeodera, lagunae and transversa, described in

the preceding pages, and the new subspecies of Agaeocera, added

a number of new records to our list of Buprestidae from Lower

California. They are as follows:

Acmaeodera flavomarginata Gray. San Pedro, 15 miles N. of

San Ignacio, Las Animas, Sierra Laguna, San Venacio, and 20

miles N. of Comondo.

Acmaeodera scapularis Horn. Las Animas, San Venacio and

Agua Caliente.

Acmaeodera gibbula Lee. Las Animas and 15 miles S. of San

Domingo.

Acmaeodera clausa Horn. Pescadero.

Acmaeodera opinabilis Fall. Big Canyon, Sierra Laguna.

All of the above localities are in Lower California and all speci-

mens collected in these localities were by Ross and Bohart and

during October, 1941.

Additions to the Lower California list of species, overlooked

in my previous paper, are:

Paratyndaris olneya (Skinner), 15 miles S. of San Domingo

(Ross and Bohart Coll.). This species has generally been col-

lected in various places in southern Arizona and several were

taken at Jacumba, San Diego County, California, by W. F. Barr.

Paratyndaris albojasciata Knull, 25 miles S. of Santa Rosalia

(Ross and Michelbacher Coll.) . The type locality for this species

is Tucson, Arizona.

T aphrocerus schae fieri Nicolay and Weise, Big Canyon, Sierra

Laguna. (Ross and Bohart Coll.). This species has previously

been collected in Southern Arizona, in the State of Sonora, Mex-

ico, and on various islands in the Gulf of California as Santa

Isabella Island (Academy Expedit. 1932).

MIGRATION OF VANESSA CARDU1 (LINN.)

The following observations on the spring movement of the

painted lady, Vanessa cardui (Linn.), were made during 1945.

For a fuller account of the habits of this butterfly see Williams

(1930, The Migration of Butterflies xi - 473 pp. Oliver and Boyd,

London). On April 16, 1945, adults of Vanessa cardui were ob-

served flying in a northeasterly direction at numerous points in

the vicinity of Mt. Diablo, Contra Costa County, California. No

massed flights were observed but all individuals were flying in

the same general direction. At a point 5 miles south of Antioch

counts were made of the numbers passing a single station. The

weather was clear and a breeze was blowing rather briskly from

the northwest. At 3:00 p.m., 48 specimens passed a line about 70

yards wide in ten minutes. Another count along a road gave 26

specimens passing a line 100 feet wide. Most individuals were

flying two to four feet above the ground although a few flew as

high as twenty feet. They were flying approximately 20 m.p.h.

Most of the specimens were worn. On April 23 the numbers were

considerably reduced and by April 26 only an occasional speci-

men could be seen flying. — Ray F. Smith and E. Gorton Linsley.

FURTHER NOTES ON SOME SPECIES OF PLEOCOMA

(Coleoptera, Scarabaeidae)

BY E. GORTON LINSLEY

University of California, Berkeley

Pleocoma venturae Linsley, new species

Male: Form large, robust, broadly oblong-oval, only moderately

convex; integument mostly dark or reddish-brown; pubescence

golden yellow. Head coarsely punctate, with a broad smooth band

extending from antero-basal angle of ocular canthi to base of

vertical horn; clypeus moderately coarsely, irregularly punctate,

clothed with long erect hairs, anterior process with anterior face

nearly vertical, slightly concave, apex deeply, obtusely notched,

apical angles moderately acute; vertical horn elongate, gradually

narrowed toward apex, apex with a broadly arcuate notch, surface

clothed with long hairs; ocular canthi projecting forward slightly

from a right angle, anterior margin slightly concave; palpi and

antennae reddish, lamellae brownish, scape conical, about twice as

long asi apical width, second segment moniliform, about twice as

wide as long, third segment elongate, slender, about as long as

scape, at least three times as long as greatest width, fourth seg-

ment with an acute process, segments five to eleven distinctly

lamellate, lamella of fifth segment two-thirds as long as that of

sixth, lamella of sixth more than three-fourths as long as that of

seventh segment, that of eighth a little shorter than ninth, lamella

of ninth segment longest, those of tenth and eleventh segments

decreasing in length, ratios of segments five to eleven 26:36:43:

44:45:42:38. Pronotum approximately twice as wide as long,

barely widest at posterior angles, posterior angles rounded, ante-

rior concavity a little more coarsely punctate than disk, sub-

glabrous, lateral discal impressions usually at middle, pubescence

fine, sparse; legs clothed with long, golden hairs. Elytra together

about one-fourth longer than broad, surface shining, finely, sparsely

punctate, geminate striae very feeble. Abdomen reddish-brown,

sternites coarsely but irregularly and not closely punctate. Length

27.5 mm.

Female: Form elongate oval, widest behind middle; color dark

reddish-brown. Head with clypeus broadly expanded apically,

angles prominent, median notch shallow; vertical horn very short,

consisting of little more than a pair of lobes; antennae pale red-

dish, lamellae brownish, fourth segment angulate, fifth with a

broad as long, widest at posterior angles, distinctly and closely

punctate, punctures larger and denser anteriorly, disk with a

vague, sparsely punctate, median longitudinal line; scutellum gla-

brous, sparsely punctate. Elytra widest behind middle, length to

breadth as 28:23, surface deeply but irregularly punctate. Length

38 mm.

Holotype male (No. 5462, Calif. Acad. Sci., Ent.) and twenty-

seven paratypes, also males, from Squaw Flat, Sespe Canyon,

Ventura County, California, December 11, 1937 (R. E. Bar-

rett) . I have associated with these, but not designated as allo-

type, a female, supposedly from Sespe Canyon but with the

locality open to question, also from the collection of Mr. Barrett,

to whom the writer is very much indebted for the privilege of

studying the species.

P. venturae is a member of the conjungens group. It differs

from conjungens by its larger size (male 24-30 mm. as compared

with 20-23.5 mm.; female 38 mm. as compared with 26-28 mm.),

the fourth antennal segment angulate, not lamellate, and the

ocular canthi of the male projecting at an angle. The female

further differs from that of conjungens by having the clypeus

broadly expanded and angulate with the margin shallowly

notched, and the pronotum and elytra more deeply punctate.

From P. lucia, it differs in having a distinct lamella on the fifth

segment of the antennae which is at least half as long as that of

the sixth segment, and the pronotum widest at the basal angles.

It also differs from lucia in size (26-28 mm. as compared to 23

mm.). From the remaining members of the conjungens group,

blaisdelli, hirsuta, nitida, and badia it may be immediately dis-

tinguished by the sparsely punctate, sparsely hairy, anterior pro-

notal impression.

Pleocoma australis Fall

Males of this species were captured during a heavy rain at

Mountain Center, San Jacinto Mountains, California, October 24,

1941, by Mr. D. DeLeon. At 3 P.M. on the same day, additional

specimens were captured during a drizzling rain 2 miles north

of Kenworthy Ranger Station, also in the San Jacinto Mountains.

On October 26, 1940, males were flying at Lake Hemet 1 , the only

other record from the San Jacinto Mountains.

Pleocoma badia Fall

Three males of P. badia were taken by Mr. R. E. Barrett on

Strawberry Peak, Tujunga Canyon, Los Angeles County, Califor-

nia, December 1, 1922. In one example the pronotum is piceous,

as is true also of one specimen in my series from Mt. Wilson,

the only previously known locality for the species.

Pleocoma behrensi LeConte

To the recorded localities for this species may be added Half

Moon Bay, San Mateo County, California, October 30, 1937 (L.

Jensen). This provides the most extended record for the species

in a southwesterly direction.

Pleocoma fimbriata LeConte

Previously known only from El Dorado County (Placerville

and Snowline) and Placer County, California. Taken at Nevada

City, Nevada County, California, October 26, 1940, by W. F.

Barr.

Pleocoma rickseckeri Horn

This species has heretofore been known only from the type

locality: Sylvania, Sonoma County, California. It also occurs at

Santa Rosa, Sonoma County and in Napa County at Angwin,

California, where males were captured flying in the rain, on

November 9, 1940, by Mr. M. I. Sherman.

Pleocoma tularensis Leach

Specimens in the collection of Mr. B. E. White are from 10

miles south of Mariposa, Mariposa County, California, providing

the northernmost record for this species. Males were also taken

at Northfork, Madera County, California, December 14, 1936, by

T. W. Daniel.

Pleocoma hirticollis vandykei Linsley

A series of more than one hundred males and sixteen females

of this subspecies, captured at Patterson Pass, Alameda County,

California, by R. F. Smith, R. W. L. Potts, A. E. Michelbacher,

and the writer, has afforded an opportunity to investigate varia-

Although the size ranges indicated above are outside of those

ascribed to P. hirticollis hirticollis Schaufuss (males: 25-28 mm.;

females: 33 mm.), this is probably the result of a different

method of measurement. Of more significance, perhaps, is the

relatively narrow size range evident in the sample. It remains

to be seen whether or not other species exhibit a similar uni-

formity.

A male of vandykei was captured at Lafayette, Contra Costa

County, California, on November 5, 1944, by R. F. Smith.

Pleocoma dubitalis Davis

Males and females of P. dubitalis dubitalis Davis were cap-

tured by K. M. and D. M. Fender, along Baker Creek, about 8

miles westnorthwest of McMinnville, Yamhill County, Oregon, on

October 23, 1938. Elytra and other fragments have also been

found by Mr. and Mrs. Fender along Panther Creek, 2 miles

north of McMinnville. In the Baker Creek area, males were

captured flying near dusk through sparse woods of Douglas fir,

Pseudotsuga taxifolia, during the fall rainy season. Males were

also taken along rather hard packed paths, as many as four or

five together, attempting to dig down to females.

Pleocoma sp.

Imperfect specimens of an undetermined species of Pleocoma

were taken in a forested area near Lyonsville, about 30 miles

east of Red Bluff, Tehama County, California, in the fall of 1935

by A. N. Smoot. They represent the first record for the genus in

Tehama County and appear to belong to the shastensis-carinata-

simi group.

Pleocoma sp.

Mr. H. H. Keifer has called my attention to larvae of Pleocoma

from Leona Valley, Palmdale, Los Angeles County, California,

where they were injuring apple roots. It is not possible at pres-

ent to state just what species these represent, but in view of the

nearness of the locality to the Sierra Madre Mountains it is pos-

sible that they may prove to be P. badia Fall, or, a little less

likely, P. hirsuta Davis.

Pleocoma sp.

In the University of California collection there is a female

Pleocoma from Mt. Diablo, Contra Costa County, California, col-

lected by Mr. L. M. McQuesten. No species has been recorded

previously from this mountain and in view of its isolation it is

highy probable that it represents an undescribed species. The

specimen clearly belongs to the behrensi group and appears to

be related to sonomae Linsley as indicated by the 4-lamellate

antennal club with the seventh antennal segment transverse, an-

gulate but not lamellate. The vertical horn is very shallowly

notched at the apex, the clypeus rounded.

BIOLOGICAL NOTES ON PLEOCOMA HIRTICOLLIS

VANDYKEI LINSLEY

(Coleoptera; Scarabaeidae)

BY R. F. SMITH AND R. W. L. POTTS

University of California, Berkeley

The discovery of this species in considerable numbers results

in the establishment of a habitat new to the Pleocominae. Here-

tofore the known and recorded habitats were primarily in a forest

association, secondarily in chaparal, now, for the first time, a

habitat is known in the open, hilly grassland. The following

fragmentary notes are therefore of interest.

Collection data: January 21, 1944, near Patterson Pass,

eastern Alameda County, California, three elytra of a Pleocoma

were found at two ground squirrel middens by the authors. Oc-

tober 30, 37 S 8 were collected by E. G. Linsley and Ray F.

Smith. November 4, 78 S £ and 17 2 2 were collected by E. G.

Linsley, A. E. Michelbacher, and the authors. November 14,

A. E. Michelbacher and Ray F. Smith were unable to find speci-

mens at the locality after a week of dry weather.

Locality data: Approximately one-half mile east of summit

of Patterson Pass, extending about one-fourth mile south and

one-half mile north of road, altitude between 1,150 and 1,350

feet, in the rolling, grassy hills extending from Mount Diablo

southward, forming the western boundary of the San Joaquin

Valley.

The general aspect is of grass pasture land in an area of nu-

merous hillocks, gentle slopes and small gullies. The entire area

slopes in a more or less northeasterly direction, following a small

intermittent tributary of Mountain House Creek. The drainage,

in general, is good but one or two small ponds form in winter

where there is no outlet to the stream.

The soil, as described by Cole, et. al. 1 , belongs to the Linne

series and the greater part of the area is a dark brownish hard

adobe with some rock outcrop of the clay loam phase. Most of

the females were taken near this latter, although they were not

limited to this part of the area, being found south of the road as

well.

[VOL. XXI, NO. 3

In the spring the entire area is covered by such plants as

Er odium, Echinocystis fabacea, Lupinus, Trifolium, Viola pedun-

culata, Broadiaea capitata. Ranunculus calif ornicus, and a num-

ber of grasses. As is common in this hilly area most of the

pasture land is covered with introduced plants. It is not known

whether this station has ever been cultivated, but the area has

been pastured for at least three years. The rather deep gully

alongside the station contained the characteristic stream border

plants of this area, such as Salix, Sambucus, Rosa, etc.; how-

ever, the beetles were definitely not associated with any of these.

Ground squirrel burrows are common at the northern portion

of the site and scattered everywhere. Stenopelmatus and spider

holes are also exceedingly numerous.

Specimens were taken over a wide area, although they were

more concentrated near the outcrop before mentioned and at and

near a small gully to the south of the road.

Weather data: As previously recorded 2 , emergence of cer-

tain Pleocoma depends on a soaking rain of about one-half inch

or more. This proved true for vandykei as well. Records for the

season of 1944 are as follows for nearby points:

The Lathrop station is approximately 20 miles to the east in

the San Joaquin Valley. The Livermore station is 9 miles to the

west, on the other side of the hills. The Young Ranch is nearest

to the locality and in a somewhat similar area 2.25 miles to the

northwest.

In the Patterson Pass area there probably was a light rain of

about a tenth of an inch on October 20 and 21. The second rain

of the season, October 30 and 31, would have been about three-

fourths of an inch, or more. The third rain, November 3 to 5,

was about equal in precipitation.

Male flight behavior: Males were observed flying from

12:00 noon until 6:15 P.M., under conditions that varied from a

heavy rain to late afternoon sunshine to after dark, and from a

slight breeze to a strong northwest wind. They appeared to be

most abundant about the middle of the afternoon. On the whole,

the weather was rather cold and threatening.

The normal flight pattern was a slow sweeping flight back and

forth over the ground apparently in search for female burrows.

These searching flights were made for about 50 to 200 yards

mainly into the wind. Then a long, straight, return flight was

made down wind and the searching flight would begin again.

While going upwind the progress of the male Pleocoma was

slow and one could keep up with them by walking slowly, but

on the downwind flight one had to run hard to keep the beetle in

sight. The entire flights were frequently of long duration. In one

instance a male was followed on his route for over a mile. While

searching, the males usually flew about twelve to eighteen inches

or even less above the surface of the ground, but on the down-

wind flight they flew as high as ten to fifteen feet. When knocked

to the ground by flying into plants they would crawl a few inches

and then take wing again. Along toward dusk an occasional male

would begin to dig into the soil. This was not in search of

females, but in preparation for resting or spending the night.

Apparently the males pass the night a few inches beneath the

surface.

The males were not attracted to a Coleman lantern.

Female behavior: No females were found on October 30. On

November 4, seventeen females were removed from their bur-

rows. Most of the females were in the dry soil, i.e., below the

penetration of the rain, at depths varying from about three to ten

inches. Most of the holes were open, but in several instances the

holes had been plugged. After copulation, the female apparently

retreats to lower depths in the soil. There did not seem to be any

special area where the females were concentrated. In several

cases, one to four males were either in or near the female bur-

row. The diameter of a female burrow was measured as seven-

eighths inches. In five instances cast pupal or larval skins were

found at the bottom of the female hole.

Larvae: While digging for the adults, four larvae were un-

earthed. These were of three sizes: the smallest, about three-

eighths of an inch in length, the largest of a size approximately

equal to that of the beetle, and two about midway between. This

118

PAN-PACIFIC ENTOMOLOGIST

[VOL. XXI, NO. 3

would seem to indicate a life-cycle of more than one year for this

species.

Summary : It seems evident from our observations in this

locality that Pleocoma hirticollis vandykei Linsley is a pasture

land form. A rain of about one-half inch is apparently necessary

to release the males in the fall. The males emerge before the

females and search out their burrows. They enter the female

tunnel to copulate. After copulation the female plugs her bur-

row and passes downward. The males spend the nights in small

burrows which they dig each night. The life cycle is apparently

of at least two or three years duration, the larvae feeding on one

or another, or perhaps generally on the roots of the pasture-

grassland plants.

ABUNDANCE OF HYPERA PUNCTATA (FABR.) IN 1945

Under usual conditions of weather and enemies, the clover-leaf

weevil, Hyper a punctata (Fabr.) never reaches a population level

in California where it can do economic damage. The distribution

and damage by this weevil have been discussed in a previous

note (1944, Pan-Pac. Ent. 20 (3) :120). At that time it was sug-

gested that a fungous disease of the larvae which is very common

in the winter and spring is associated with the low population

levels. In all probability this disease is dependent on weather con-

ditions for its effectiveness.

In the spring of 1945, the clover leaf weevil bred up in very

large numbers on bur clover, Medicago hispida, at various stations

in Contra Costa and Alameda counties. Larvae were very abun-

dant in April and there was little fungous disease. The absence of

the disease may be associated with the unusually dry and warm

April. These larvae reached maturity near the end of April and

early in May and adults were very abundant after the first week of

May. The adults remained abundant in the grasslands for about

three weeks or until the plants were completely dried up. At this

time numerous complaints were received from home gardeners

and others situated near the open uncultivated area. The adult

weevils moved into the yards and houses in very large numbers

and caused considerable annoyance. The adults were also observed

collecting at watering troughs.

In 1944, a similar outbreak occurred in Scott Valley, Siskiyou

County. In this case the clover leaf weevil caused considerable

defoliation to alfalfa. — Ray F. Smith and A. E. Michelbacher.

ESSIG — HY ALOPTEROIDES PALLIDA

119

HY ALOPTEROIDES PALLIDA THEOBALD, AN APHID

NEW TO NORTH AMERICA

(Hemiptera, Aphididae)

BY E. O. ESSIG

University of California, Berkeley

This very interesting and little-known aphid was recently

collected on orchard grass, Dactylis glomerata L., growing in a

greenhouse on the campus of the Oregon State College, Corvallis,

Oregon, on February 24, 1945, by D. C. Mote and H. E. Morrison.

The latter succeeded in taking a good series of all stages of

apterous and several alate females. The alates were the first of

this stage so far procured. The specimens were forwarded in

alcohol to me for determination. In response to my request another

collection was made by Mote and Morrison on April 12, so that

altogether some 50 adults were prepared and mounted on micro-

scopic slides, some of which were returned to the collectors. The

aphid is a pale yellowish-green species somewhat pulverulent and

of a grayish or whitish cast. It occurs in seclusion between the

culmns and leaves or in the heads and may also possibly occur at

the bases of the plants and even about the roots.

The history of this aphid is short and interesting. It was

described as a new genus and new species by F. V. Theobald

(Entom. 49:51-2, 1916) from a single adult apterous female taken

in a nest of the black ant, Acanthomyops niger (L.), at Porlock

Weir, Somerset, England, May 14, 1915. Its most marked charac-

ters are the presence of 4 or 5 sensoria on antennal segment III

of the apterae ; the large, almost spineless cauda ; the small, corru-

gated cornicles ; and the row of 18-20 circular sensoria on antennal

segment III of the alatae which extend over the full length of the

segment excepting the basal area. Later Theobald (Plant Lice or

Aphididae of Great Britain, 1 :224-5,1926) reported other apterous

specimens taken on a potato leaf at Swordale, Evanton, Ross-

shire, Scotland.

While collecting aphids in England, I was fortunate enough to

take a large series of additional apterous forms of this aphid by

sweeping grasses along the roadside, at Reigate, Surrey, England,

on May 20, 1937, shortly before leaving that country. Specimens

of these, in my collection, have served for the identification of the

Oregon specimens.

[VOL. XXI, NO. 3

Since this insect has never before been observed in North

America it may possibly have been introduced. However, there is

as yet no possible clue as to how this may have occurred. So far

as known the aphid is of no great economic importance.

CEPHENEMYIA JELLISONI TOWNSEND (DIPTERA

CUTEREBRIDAE) REARED FROM NASAL

BOT OF BLACKTAILED DEER

BY CARLTON M. HERMAN

California Division of Fish and Game

San Francisco, California

Very few Cephenemyia spp. have been reared in captivity.

Numerous attempts by the author, prior to the one reported here,

were unsuccessful.

On January 22, 1945, Warden C. L. Gourley examined a deer

( Odocoileus hemionus columbianus ) found dead near Big Bar,

Trinity County, California, at an elevation of approximately

1,250 feet. Three maggots were removed from the nasal cham-

bers, wrapped in waxed paper and shipped to the author for

study. On examination after arrival in San Francisco on Janu-

ary 25, the specimens were found to be two fully pigmented

third stage larvae and a pupa of Cephenemyia sp. All three

specimens were placed in a closed pint jar and kept at room

temperature. The two larvae pupated within a few days but col-

lapsed in the process. A fly emerged from the pupal case on

February 15, 1945, after a period of 21 to 24 days.

The fly was identified as Cephenemyia jellisoni Townsend.

Identification was verified by Dr. M. T. James of the U. S.

National Museum. The specimen has been deposited in the col-

lection of the Division of Entomology and Parasitology of the

University of California at Berkeley.

The only other published record of the successful rearing of

this fly in captivity was reported by Jellison (1935, Proc. Hel-

minth. Soc., Washington 2:69) from maggots collected from deer

(' Odocoileus hemionus) in Montana on April 28. The several

flies he was able to rear all required a pupal period of more

than 50 days. Jellison originally reported his specimens as C.

pratti, but they were later described as C. jellisoni by Townsend

(1941, Jour. N. Y. Ent. Soc., 49:161-163).

NOTES AND DESCRIPTIONS OF AMERICAN

POLYCTENIDAE

(Hemiptera)

BY G. F. FERRIS, Stanford University

AND R. L. USINGER, University of California

The present paper is a supplement to the revision of “The

Family Polyctenidae” (Ferris, G. F. and Usinger, R. L., 1939,

Microentomology, 4(1) :l-50, 25 figs.). The additional material

that has become available since 1939 includes eleven slides

kindly sent to G. F. Ferris by A. da Costa Lima from the Insti-

tute de Oswaldo Cruz, one slide loaned to G. F. Ferris by Dr. J.

Bequaert from the Venezuelan collections of Pablo J. Anduze,

and two slides loaned to R. L. Usinger by Dr. Robert Matheson

of Cornell University. One of the Cornell specimens is likewise

from Venezuela (Anduze) and the other is the specimen upon

which Matheson based his Costa Rican record of Hesperoctenes

tarsalis.

Morphology

The Brazilian material from da Costa Lima includes a last

stage nymph of Hesperoctenes eumops Ferris and Usinger and

two unidentifiable nymphs with perfectly distinct dorsal abdom-

inal scent glands located on the posterior margins of the 4th,

5th and 6th abdominal segments. It is not clear why scent glands

are visible in these specimens and not in the other polyctenid

nymphs available for study. The polyctenid scent glands resem-

ble the nymphal glands of the bed bug and are another point of

similarity between the two families. A search in adult poly-

ctenids for metasternal scent glands similar to those found in the

Cimicidae failed to reveal any comparable structures. However,

the “second pit of undetermined homologies” located “near each

sternal apophyseal pit” (Ferris and Usinger, 1939) is in the

proper place and may represent the scent gland opening that is

so typical of Cimicoidea and most other Heteroptera.

The ventral surface of the polyctenid head appears to differ

from that of other Heteroptera in that the posterior tentorial pits

122

PAN-PACIFIC ENTOMOLOGIST

[VOL. XXI, NO. 4

of the head are adjacent to the inner limits of the genal ctenidia.

By definition, then, (Snodgrass, 1935) the median region poste-

rior to these is apparently the gula rather than the hypostomal

bridge as in other Heteroptera. Hence the small comb at the

posterior margin of the ventral surface of the head should be

called the “gular comb.”

Hesperoctenes eumops Ferris and Usinger

Seven slides of this species are at hand including one teneral

adult male in poor condition, one perfect adult female and five

nymphs. These are the specimens referred to by Ferris and

Usinger (p. 22) as “Hesperoctenes species.” They are labelled

“ ? Hesperoctenes longiceps Waterhouse, Malossus perotis, Cam-

pos, VI-1920, A. C. Pestana Coll.” and were prepared and de-

termined by da Costa Lima. The well-preserved female differs

from typical eumops only in having slightly fewer (12) stout

bristles on the metapleurites. In the shape of the head, general

chaetotaxy, body proportions, and size this female falls well

within the range of variation exhibited by the typical California

series of eumops. The male has the apex of the intromittent

organ distinctly sinuate but this is probably due to the fact that

the specimen is in a bad state of preservation.

Hesperoctenes fumarius (Westwood)

A single male specimen from Turrialba, Costa Rica, 2500

feet, August 7, 1927, W. V. Hamilton, has been received from

Dr. Matheson. It bears a label “ Hesperoctenes tarsalis Horv.”

(Matheson, 1928, Parasitology 20:174) and may, indeed, be

that species although, if so, it can scarcely be maintained as

distinct from typical West Indian fumarius. The specimen agrees

perfectly with Cuban specimens of fumarius except for the naked

middle and anterior portions of the metasternum. However, the

metasternum shows some evidence of bristles having been broken

off. The fourth antennal segment is slightly longer than the

second or third but is attenuated apically, possibly due to shrivel-

ing. The specimen is 2.4 mm. in length.

Dr. S. C. Bruner has five specimens of typical fumarius from

Molossus tropidorhynchus Gray collected from the buildings of

the Estacion Experimental Agronomica at Santiago de las Vegas

by L. C. Scaramuzza.

FERRIS AND USINGER— FOLYCTENIDAE

123

Hesperoctenes limai Ferris and Usinger, new species

Head longer than broad, 24 : :22 ; labrum less than half as long

at middle as total width, 5::12%, rather evenly rounded ante-

riorly. Chaetotaxy of dorsal surface as in longicevs. Genal ctenidia

rather evenly rounded in general outline, the teeth rather strongly

projecting postero-laterally at sides. Gular bristles wanting.

Proportion of antennal segments one to four as % :1% :1% :1]4 >

the first segment with nine short, stout spurs along anterior and

basal margins and with longer bristles distally.

Pronotum half again as broad as long and about one-fourth

broader than head. Mesonotal pads as long as pronotum, each pad

about one-fifth narrower than length of pronotum or mesonotal

pad. Elevated area of prosternum a little longer than broad at

base, the anterior margin with seven very stout bristles laterally.

Elsewhere on anterior half with longer, more slender bristles and

with shorter bristles posteriorly on the disk, especially laterally

(a few of the central ones apparently broken off). Metasternum

with numerous very fine bristles near posterior and lateral mar-

gins. Metapleurites with eight or nine irregularly directed, stout

bristles arranged in two or three ill-defined rows.

Size: male 3.44 mm., female 3.86 mm.

Holotype, female, Lassance, Brazil, April 13, 1935, Em-

manuel Dias, collector, C. L. prep. Allotype, male, Sitin DU

Matto, Bahia, Brazil, April 13, 1935, Emmanuel Dias, collec-

tor, C. L. prep.

Nearest to longiceps with which it agrees in absence of gular

bristles, in its exceedingly long labrum, its relatively long, nar-

row head and dense bristles posteriorly on metasternum. It

differs from longiceps in its smaller size, its more numerous and

differently arranged metapleural bristles and the narrower head

anteriorly with larger labrum.

Hesperoctenes parvulus Ferris and Usinger, new species

Head (including labrum) as long as broad; labrum less than

three times as broad as length on median line, 8::3 (almost 4

times as broad as long in cartus, 21%::5%, and over four times

as broad, 19M>::4, in vicinus ) . Genal ctenidia as seen from above

rather strongly rounded immediately behind first antennal seg-

ment, following lateral margins of head posteriorly and laterally,

the teeth scarcely exceeding sides of head. Gular bristles seven

or eight in number, with two of these near the center set slightly

forward. Proportion of antennal segments one to four as

2% :4:3% :3%, with seven stout spurs on outer anterior side of

first segment beneath.

124

PAN-PACIFIC ENTOMOLOGIST [vOL. XXI, NO. 4

Pronotum slightly more than half again as broad as long,

3::2 a /4, much as in cartus. Mesonotal lobes scarcely shorter than

pronotum, a single lobe being one-fifth longer than broad. Elevated

portion of prosternum about as long as broad, the disk with five

very stout bristles laterally on anterior margin and twenty-six

more slender bristles arranged roughly into three rows anteriorly.

Behind these the disk is almost entirely naked except for about

one dozen small bristles laterally on apical half. Metasternal

bristles confined to the areas immediately adjacent to posterior

and lateral margins. Metapleurites with only six or eight very

stout bristles irregularly arranged into two rows.

Chaetotaxy of upper surface of entire body much as in cartus.

Size: female 2.28 mm.

Holotype, female, Sta. Maria de Epire, Guarico, Venezuela,

September, 1937, Pablo J. Anduze, received from Dr. J. Bequaert.

The specimen was taken from Glossophaga longirostris Miller, a

bat belonging to the family Phyllostomidae. A second female

from the same locality on “Vampire bat,” 1936, appears to be

slightly teneral. It differs in its slightly larger size, 2.4 mm.,

and in possessing only 5 gular bristles arranged in an irregular

row.

Closest to cartus and clearly a member of the compact cartus-

vicinus group, having bristles at middle of hind margin of head

beneath and very sparsely placed bristles over the entire dorsal

surface. The head is as long as broad and the gular bristles are

8 in number arranged in an irregular, almost double row, thus

resembling cartus. Vicinus has a shorter, broader head and fewer

bristles arranged in a single row. The elevated portion of pros-

ternum is naked at middle with only a few bristles posteriorly

and laterally, thus still more closely resembling cartus with

which it likewise agrees in chaetotaxy of metapleurites. The most

distinctive feature of parvulus is the relatively longer and nar-

rower labrum. In addition, parvulus is about two-thirds of a

millimeter smaller than cartus, the female holotype being the

smallest Hesperoctenes as yet described.

NESTING HABITS OF ANDRENA RHODOTRICHA LINSLEY

(Hymenoptera-Andrenidae)

Andrena rhodotricha was originally described from specimens

collected by G. E. Bohart and the writer at Berkeley, California 1 .

It has subsequently been taken by C. D. Michener on Salix. On

March 14, 1939, this species was found nesting in a perpendicu-

lar five foot bank on the south side of Dwight Way Hill, Berke-

ley. The burrows were constructed among the large basal roots

of a California laurel growing on the top of the bank. The bur-

row entrances were all within four to five inches of each other

and were frequently hidden by roots or cracks in the ground.

They were 5 mm. in diameter and penetrated the moist clay soil

as a smooth circular hole for from three to six inches. Numerous

cells were constructed along each burrow and were seldom more

than an inch away from those in the same or adjacent series. All

of the bees had emerged and several females had constructed

fresh burrows, the cells of which were waxed, and provisioned

with a spherical ball of pollen measuring 5 mm. in diameter. The

eggs were white, slightly bowed, and 3 mm. long by less than

1 mm. wide. This species was also found nesting at the Orinda

Crossroads, Contra Costa County, in February, 1940. The mature

bees were unemerged and were taken from cells among the roots

of a California buckeye at the top of a six foot bank. — J. W.

MacSwain.

A NEW GENUS— RETUSANUS— AND FIVE NEW SPECIES

OF MEXICAN LEAFHOPPERS

(Homoptera, Cicadellidae)

BY DWIGHT M. DeLONG

Department of Zoology and Entomology, Ohio State University

The members of the Genus Retusanus are characterized by

being densely covered by minute brown spots. They are appar-

ently Deltacephaloid in type, the elytron resembling the vena-

tion of this group. There are many costal veinlets, the central

anteapical cell is long, the outer anteapical cell is shorter and it

is often divided into two or more cells. The vertex is flat or

concave between the eyes and forms a definite margin with the

front. The vertex is rather short and broadly rounded on the

margin. The long ovipositor exceeding the long narrow p3^gofer

indicates a definite relationship to the Aconuran group.

Type of genus Retusanus punctatus DeLong.

The species of this genus are very similar in coloration and

appearance and can be separated by the male genital structures.

The styles and pygofer spines are quite different in the different

species while the aedeagus in lateral view shows some differences

in certain species.

Retusanus punctatus DeLong, new species

A broad headed species marked with minute brown peppered

spots. Length male 4 mm.

Vertex broadly rounded, appearing almost parallel margined,

less than two-thirds as long at middle as basal width between eyes.

Color: Vertex pale with ocelli and two spots between them just

above margin, brown. These four brown spots are about equidistant

from eyes and from each other. Remainder of vertex sparsely

marked with minute brown spots. Pronotum and scutellum brown,

densely marked with minute brown spots. Anterior margin of

pronotum behind eyes and basal angles of scutellum, rusty brown.

Elytra pale subhyaline, veins dark brown, a few minute brown

spots on clavus and basal portion. Face pale, rather evenly and

densely marked with minute brown spots.

Genitalia: Male aedeagus rather short, erect, apical third with

a broad notch dividing it into two portions, an anterior narrow

portion, blunt at apex, and a posterior broader portion with a

pointed apex. Plates about twice as long as basal width, tapered

136

PAN-PACIFIC ENTOMOLOGIST [VOL. XXI, NO. 4

to blunt, rounded apices. Style long, rather narrow, deeply round-

edly notched on outer margin just before apex, forming a slender,

outwardly curved apical portion which is narrow but truncate at

tip. Pygofer with a long basal spine which extends to apex of

pygofer and a short black plate with several teeth arising just

before apex of plate.

Holotype male and paratype males collected at Iguala,

Guerrero (elevation 2400 ft.), October 25, 1941, by Good and

DeLong.

Retusanus pulverus DeLong, new species

Resembling pwnctatus in general appearance but with vertex

more produced, and distinct genitalia. Length, male, 4 mm.

Vertex roundedly rather broadly produced, less than two-thirds

as long at middle as basal width between the eyes.

Color: Vertex white, ocelli brown. A pair of proximal oblique

spots just above margin at middle. The portion of the pronotum

basal to the anterior margins of the eyes densely marked with

minute brown spots. Pronotum and scutellum brown, densely

marked with minute brown spots, a white spot on each margin of

scutellum half way between base and apex. Elytra pale subhyaline

with dark brown veins, claval area and central portion of cells of

corium densely marked with minute brown spots. Face pale, a

band just below margin unmarked, the other portions of face

densely marked with minute brown spots.

Genitalia: Male plates rather short, broad at base tapered to

bluntly pointed apices. Adeagus short, erect, broadened on apical

half, broadly notched at apex forming a blunt anterior portion

and a posterior portion which is pointed on apical caudal margin.

Styles long, rather narrow, broadly shallowly excavated on outer

margin just before apex. The apical third is curved outwardly

narrowed to apex which is pointed on outer apical margin. The

pygofer has a short basal spine which is not as long as plate and

a black plate with several teeth which is just at apex of plate.

recorded from the Atlantic States and for many years from the

seaboard areas of Washington and Oregon, has recently been

found on the sea beaches to the west of San Francisco. In former

A NEW COENONYCHA FROM CALIFORNIA

(Coleoptera, Scarabaeidae)

BY ROBERT W. L. POTTS

University of California, Berkeley

Heretofore the members of this genus have been primarily

associated with chaparal. The discovery of this apparently new

species in an area of grass pastureland adds a new habitat to

those previously known. Fragmentary biological notes are there-

fore included as being of probable interest.

Coenonycha pascuensis Potts, new species

Medium-sized, narrow; pale testaceous with elytral suture,

margin and base, pronotal margin and two lateral spots, and head

slightly to considerably darker (in life with a reddish cast, lost

in dried specimens) ; metathoracic wings fully developed in both

sexes.

Male: Head largely punctate, vertex with small, irregular

largely impunctate area and front with largely clear short mesal

line above suture; front with punctures often contiguous or sub-

continguous in irregular short rows sometimes separated by one-

third to one-half the width of a puncture, punctures less dense over

vertex, again crowded over eyes; clypeus densely punctate and

punctures larger, contiguous or subcontiguous; lateral margin of

clypeus narrowly, slightly reflexed at base to strongly so at apex

and anterior margin, only slightly less elevated at middle than at

angles, not smooth on reflexed surface; clypeal suture distinct

throughout, strongly, evenly arched toward base at middle, in

shape of a bow; antennae 10-segmented. Pronotum widest at

strongly rounded hind angles which are at about middle, margin

evenly rounded behind, slightly sinuate before to the barely pro-

duced, slightly acute anterior angles; surface smooth, shining,

punctures very irregularly placed, thickest at or behind middle

toward sides (about one puncture width between), sparse anteriorly

and mesally (two to five puncture widths between), nearly absent

at base, each with a short seta. Elytra with side margins sub-

parallel; humeral umbones prominent; costae barely evident as

partial, paired rows of punctures, fourth or outer pair most

distinct; surface nearly smooth and shining, translucent, so

veins and folding of wing beneath apparent; punctures irregular

in size and placement, deep, but without distinct edges, larger

ones each with a short seta. Venter with punctures less dense than

above, small to large, metasternum longer than width of hind

PAN-PACIFIC ENTOMOLOGIST [yOL. XXI, NO. 4

coxal plates; foretarsi with first segment extending well beyond

apical tibial claw; all tarsal claws cleft apically, outer tooth largest

and longest. Length 8.5 mm., width 3.75 mm.

Female : Similar to male but more robust, more rounded; clypeal

margin more strongly reflexed, especially at outer angles, nearly

smooth on reflexed surface; head and pronotum not so densely

punctate, punctures more evenly spaced, setas much shorter above;

foretarsi with first segment not extending beyond apical tooth of

tibia; tarsal claws cleft subapically with inner tooth very fine.

Length 9 mm., width 4.25 mm.

Type material: Holotype male and allotype female taken in

copulation 4-2-45, two and one-half miles west of Byron, Contra

Costa County, California, in the collection of the California

Academy of Sciences (Nos. 5468 and 5469) . Eight hundred

and twenty-eight paratypes 1 from the same locality, one collected

3-8-45 by Ray F. Smith, eleven collected 3-19-45 by Ray F. Smith,

seven hundred and ninety-six collected 4-2-45 by Ray F. Smith

and the author, twenty-two collected 4-9-45 by the author, in the

collections of the author, the University of California, California

Academy of Sciences, and others. Those collected on the first

two dates and on the last date, as well as thirty-nine of the total

on 4-2-45 were taken at roots, while the remainder were taken

after dark in sweeping.

The relationships of the species are apparently with C. pallida

and C. lurida, both of which are southern California species

found on shrubs. It is closest to pallida in appearance, and keys

out with it in the Cazier and McClay key. It may be separated

from pallida by a -number of characters, the somewhat produced

and slightly acute anterior pronotal angles and slightly sinuate

margins before the hind angle, the rather inevident costae, the

presence of large punctures on the venter, the different charac-

ter of the clypeal margin apparently being the best. Unfortu-

nately all known specimens of pallida are unavailable for com-

parison at present due to war conditions. It is probable that

better characters for differentiation will be found to exist when

these specimens are again available.

This species was discovered by Mr. Smith while searching for

hibernating Diabrotica. The area where it is now known is in

1 In a Revision of the genus Coenonycha by Cazier and McClay (Amer. Mus.

Novitates 1239, July 19, 1943) paratypes from the type locality are referred to as

paratopotypes, a term which appears unfortunate, although the intended signifi-

cance is valid. Topoparatype, while lacking the euphony of the other, seems to

this author to more clearly convey the intended meaning.

the open, grassy foothills to the east of Mount Diablo, in the

range which forms the western boundary of the San Joaquin

Valley. The general aspect is of pastureland. The site from

which all the specimens were taken is less than an acre in extent,

on a northeast exposure which varies in slope from about five to

thirty per cent.

The plants are primarily annuals, and a majority are not

native: Er odium botrys, Avena, Hordeum murinum, Lupinus,

Medicago hispida, Brodiaea capitata, and Echinocystis fabacea.

A few native grasses may be present in small numbers. Trees

and shrubs are absent from the area, although an occasional oak

tree occurs on the same hillside. The soil type, according to

Carpenter and Cosby 2 is Contra Costa sandy loam. Scarab larvae,

of two sizes, were found in soil samples but have not been identi-

fied as this species as yet, nor was their association with any one

plant possible.

The adults apparently spend the day partially or completely

but not deeply buried in the soil near the roots of the various

plants. Observation at the site, and soil samples brought into the

laboratory and sifted confirmed the fact that specimens were

most common in portions of the area where the soil was some-

what moist and plants were of medium height, about 6 to 8 inches.

They were less common in tall grass and manroot clumps where

the soil was more moist, nor were they common in portions of

the area where the soil was dryer and the plants short. In sweep-

ing, the specimens appeared to be most common in areas of

medium plants.

Less than six per cent of the specimens taken in sweeping

were females, whereas approximately fifty per cent of the speci-

mens taken at roots were females.

The species, so far as is known, is quite localized, not being

found in similar areas to the north a distance of only a few miles.

This absence from these areas is not positively proven as a night

search was not possible, however, a thorough day search was

completely unfruitful. It would nevertheless be the opinion of

the author that further investigation will prove the species wide-

spread in the sandy loam pastureland along the foothills border-

ing the San Joaquin Valley.

SCHUSTER— PHOTOPSIS

149

AN INTERESTING NEW BRACHYPTEROUS SPECIES

OF PHOTOPSIS

(Hymenoptera, Mutillidae)

BY R. M. SCHUSTER

Cornell University, Ithaca, N. Y.

Brachypterous Mutillidae are not often encountered; in North

America Myrmilloides grandiceps (Blake) is constantly brachy-

pterous, Dasymutilla waco (Blake) occasionally brachypterous,

rarely apterous, Dasymutilla hector (Blake) very rarely brachypt-

erous, and Morsyma ashmeadii Fox, as far as is known, is apter-

ous. These are the only previous records of brachypterous and

apterous male Mutillidae from North America; therefore, the

discovery of a new short-winged form is of some interest. As far

as can be judged, the specimen is a fully developed, not teneral,

and the wings are fully developed and hardened.

Photopsis brachyptera Schuster, new species

Male. Length 4.7 mm. Rufo-ferruginous, the legs and antennae

considerably lighter, more yellowish ; very weakly setigerously

punctured, except for the alitrunk, which is largely areolate-

reticulate, the pubescence sparse, silvery, erect, pilose; wings

greatly abbreviated, not reaching beyond petiole.

Head, including eyes, 1.05 mm. wide (1.1 as wide as thorax in

front of tegulae), rather moderately extended behind the eyes, the

length behind the eyes 0.30 mm. (three-fourths the length of the

eyes). Ocelli rather small, the posterior behind the supraorbital

line; length of the posterior 0.12 mm.; their distance apart, 0.22

mm. (1.83 their maximum diameter) ; their distance from the

front ocellus 0.13 mm. (slightly greater than the length of the

posterior ocelli) ; their distance from the nearest eye-margins,

0.30 mm. (2.5 their length) ; the ocellar area more deeply pig-

mented than the rest of the head. Eyes somewhat silvery, dis-

tinctly facetted, 0.40 mm. long, 0.36 mm. wide. Pubescence very

moderate, of long, nearly silvery pilose hairs arising from scat-

tered, very small punctures (somewhat closer on the occiput) ; ex-

cept for these punctures the head is smooth, polished, shining.

Posterior and posterolateral angles evenly rounded into the occipi-

tal region. Antennal tubercles separated from each other by the

length of the posterior ocelli, evenly concave between and below

them, not carinate; clypeal region only moderately developed, the

distance from the anterior margin to a line drawn through the

dorsal margins of the antennal tubercles one-half of the length

150

[VOL. XXI, NO. 4

between the eyes on the frons; the anterior clypeal margin not

reflexed, not produced, medially rather strongly, evenly convex,

with scattered, long-setigerous, rather strong punctures. Mandi-

bles moderate in size, evenly curved, not elbowed, apically bluntly

bidentate, a smaller tooth within; ventrally very strongly incised

and dentate about half way from apex to base of mandible, basal

half of mandible with rather long, coarse hairs. Scape about 0.42

mm. long (as long as the first two flagellar segments), strongly

curved, moderately setigerously punctured dorsally, the hairs

rather coarse, moderately long, chiefly erect; pedicel over 1.5 times

as long as wide, two-thirds the length of the first flagellar segment;

flagellum slender, the first article twice as long as wide, the second

and third subequal in length and scarcely a fourth longer than

the first; entire flagellum silvery puberulent, the pedicel with

longer silvery hairs.

Alitrunk 0.97 mm. wide at tegulae (less than width of head) ;

humeral angles absent, but the prothorax rather square in front;

pronotum characteristically, coarsely but shallowly hexagonally

areolate-reticulate, the ridges between the areolations thin and

sharply defined; pubescence of pronotum denser than that of head,

erect, pilose, argenteous. Mesonotum similarly, but very shallowly,

obsoletely areolate, the lateral areas of it nearly smooth, except

for sparse, long-setigerous punctures, the hairs slightly ferru-

ginous-tinged ; parapsidal furrows obsolete, scarcely distinct.

Scutellum similarly, but quite deeply sculptured, not at all strongly

inflated, nearly on the same plane as the mesonotum and propo-

deum. Mesopleura and mesosternum also areolate-reticulate, the

mesosternum entirely lacking any carinae or dentate processes.

Propodeum dorsally similarly reticulate, but the reticulations much

larger; the lateral faces and the upper part of the posterior face

similarly sculptured, but the posterior face is smooth medially and

apically, except for sparse punctures that bear prominent, upward-

pointing, silvery plumose hairs; the lateral and posterior faces of

the propodeum are separated from each other at a sharp angle.

Forewings short, scarcely reaching beyond propodeum, with

the venation strongly reduced; C, R-M, CU+Cui and 1st A are

present and infuscated on the basal two-thirds of the wing; the

stigma is also distinct and infuscated; cell M is enclosed, and

slightly longer than cell Cu+Cui, which is also distinct; cell M 3 is

enclosed, except near apex; cell M 4 is entirely open on the outer

side; all other cells apicad of these are entirely absent. The hind

wings are even more reduced, and the infuscated stubbs of the

veins are limited to the basal third of the wing.

Legs lighter than the rest of the thorax, the coxae, trochanters,

femora and tibia with sparse, long, erect pilose pubescence; the

tarsi with dense, more or less appressed, fine silvery hairs; the

serrate calcars of the hind tibiae are of the same color as the legs,

the longer is three-fourths as long as the metatarsus.

Abdomen sparsely punctate and pubescent; the petiole, meas-

ured dorsally, wider at apex than its maximum dorsal length, its

basal width scarcely over a third that of the apex, gradually

dilated toward the apex, which is evenly rounded into the second

tergite, from which it is scarcely separated, even laterally; viewed

laterally, it is very weakly convex above, not at all nodose, the

anterior two-thirds are nearly plane, while the apical part is

rounded into the second tergite; ventrally it is strongly separated

from the second tergite; the flat dorsal plane moderately coarsely,

sparsely punctate, bearing long erect, silvery hairs, Second ter-

gite smooth, polished, shining, except for very few, scattered seti-

gerous punctures bearing long silvery pilose hairs; the apical

margin, in addition, with a few inconspicuous long-plumose hairs;

pigmentation of second tergite rather deeper than that of rest of

body, except ocellar region. Apical tergites similarly pubescent,

also with some scattered, sparse, small plumose hairs, nearly im-

punctate; the pygidium not margined laterally or apically. Felt

lines of second tergite less than a third the length of the tergite,

situated medially between the base and apex of the tergite; those

of the second sternite similar, but much shorter, situated behind

the median line of the sternite. Second sternite sparsely punctate,

bearing long, simple, or shortly plumose hairs, and a band of

somewhat shorter, longer-plumose hairs at apex; apical sternites

similarly, but much more sparsely pubescent, except the third

sternite, which also has a rather conspicuous band of plumose

hairs at its apex.

Holotype: Berkeley, California, October 4, 1919, in the

collection of Cornell University (Type No. 2196).

This species is the first known brachypterous Photopsidine

wasp. At first it was felt that the specimen might conceivably

be an immature specimen, in which the wings were not yet

mature, but there seems to be no evidence to support such a

thesis. It seems to be somewhat allied to Photopsis hyalina

(Blake) and Photopsis mesillensis Ckll. The absence of processes

of any kind on the mesosterna throws this species into the group

Photopsis, as distinguished from the group Odontophotopsis,

which was unfortunately founded on a generic basis. It differs

from all known species of Photopsis by the following combination

of characters: brachypterous wings, hexagonally-areolate thorax,

gradually dilated petiole sessile dorsally with the second tergite

and not at all nodose, and the mesally convex, poorly developed

clypeal area. The rather quadrate head, with small ocelli and

rather small eyes, with the head scarcely less long behind the eyes

than the length of the eyes, and the strongly ventrally incised and

dentate mandibles distinguish this species from P. hyalina and

mesillensis; hyalina furthermore differs in that the parapsidal

furrows are more distinct.

A NEW LARICOBIUS FROM OREGON

(Coleoptera, Derodontidae)

BY KENNETH M. FENDER

McMinnville, Oregon

Laricobius nigrinus Fender, new species

Males, Black and shining above, antennae brunneous, legs and

ventral surface piceous, pubescence piceous to ashy. Head wider

than long, rather finely closely punctured. Behind the antennae and

between the eyes is a rough oval of very coarse punctures. Pronotum

wider than long, widest at the middle, base slightly wider at the

angles than the apex, sides strongly sinuate, basal and apical

angles nearly equally prominent; closely punctate and with larger

coarse punctures scattered throughout. Elytra wider than thorax

at the humeri, sides faintly, arcuately divergent to the apical

third, then rapidly rounded to the suture; elytral striae composed

of large subquadrate punctures, interstriae finely, sparsely punctate.

Dorsal pubescence composed of fine erect hairs. Legs and under-

surface finely punctured and with a fine ashy pubescence which

is recumbent and sparse. Lateral lobes of the asdeagus obliquely

truncate as in L. rubidus Lee. 1 Length 2 to 2.3 mm.

Female. Piceous and with ashy pubescence, otherwise similar to

the male. Length 2.5 mm.

Holotype male, allotype female, and five paratypes, June 20,

1904, Bear Springs, Wapinitia cut-off, Oregon. One paratype,

October 29, 1933, Creston, British Columbia, collected by

G. Stace Smith.

Laricobius nigrinus can be separated from the other two North

American species by its color and the shape of the pronotum.

The color is black to piceous in nigrinus, uniformly testaceous

to dark reddish brown in L. laticollis Fall and black with a wide

red median vitta on each elytron in L. rubidus Lee. In nigrinus

the pronotum is widest at the middle and the basal margin is

wider at the angles than is the apical margin. In both rubidus

and laticollis the pronotum is widest in front of the middle and

the basal margin is narrower at the hind angles than is the apical

margin.

The author is indebted to Mr. C. A. Frost for calling his

attention to this new species.

ROSS— NEMATINE SAWFLY

153

A NEW TRIBE AND GENUS OF NEMATINE SAWFLY

( Hymenoptera, Tenthredinidae)

BY HERBERT H. ROSS

Illinois Natural History Survey, Urbana, Illinois

The following new genus, Pristola, combines many character-

istics which are unlike any known genera of Nematinae. The

venation of both wings is characterized by the atrophy of vein

2A & 3A, which would place the genus in the tribe Pseudodi-

neurini. From this tribe the genus Pristola differs in the striking

characters of the mesonotum, fig. 3. Most conspicuous of these

are the semi-obliterated praescutal structures and the long, ex-

posed postnotum of the mesothorax; the male and female geni-

talia are also of very unusual shape. In the Pseudodineurini the

praescutum is well defined, and the exposed portion of the post-

notum is short and almost hidden under the large and projecting

post-tergite. On the basis of these and other differences a new

tribe is proposed for the reception of Pristola.

Pristolini new tribe

Characteristics. Venation typical of the specialized Nematinae,

the front wings with both 2 r and the basal lobe of 2 A & 3A absent;

general proportion of wings resembling in other respects those of

Nematus. Mesopleurae with a well-defined, linear prepectal suture.

Mesonotum, fig. 3, with praescutal sutures only faintly indicated,

becoming obsolete some distance from meson; mesoscutellum with

only a narrow post-tergite which is on a level with the postnotum.

Visible portion of postnotum long and flat, so that the post-tergite

and metascutellum are far apart; metascutellum arcuate. First

abdominal tergite with its acrotergite also flat and long.

Erected for the single genus Pristola.

Pristola new genus

Characteristics. Body elongate and slender. Head wide, fig. 2,

somewhat short and stocky from lateral view; clypeus very shallow

and extending scarcely beyond the base of the mandibles. Labrum

semi-circular and of only moderate size. Antennae 9-segmented,

long and filiform, the last four segments gradually diminishing in

length, the apical segment four times as long as wide and pointed

at tip. Mandibles with lateral aspect narrow and blade-like; with

anterior aspect as in fig. 2, each mandible possessing a long curved

apical tooth and a small sharp subapical tooth. Legs slender,

apical tooth.

In the key to the genera of the Nematinae (Ross 1937: p. 75) ,

Pristola will run to couplet 9 on the basis of the atrophy of 2A

& 3A in both front and hind wings. Couplet 9 can be emended

as follows to accommodate Pristola:

lamnium divided into twelve irregular segments; the first six

sutures do not reach the ventral margin but the apical six reach

the margin and have a very small spiculella near the sclerora.

It is unusual that this species should be found in two places

so far apart. This situation is reminiscent of certain species of

Pristiphora, many of which have few known records but these

are scattered from coast to coast.

CATALOGUE OF APIOCERIDAE OF THE WORLD

BY WILLIAM F. RAPP, JR.

AND

WILLIS E. SNOW

The family Apioceridae is composed of large flies which are

restricted to arid or semi-arid regions. Very little work has been

done in this family until recently when Cazier 1 revised the North

American species and Hardy 2 revised the Australian species.

Since the publication of the Kertesz catalogue in 1906 so many

new species have been described that it has been thought advisa-

ble to bring it up to date.

The following is a comparison of the Kertesz catalogue and

the present paper.
