11. CHRYSOMELIDAE

by G. E. BRYANT

(Commonwealth Institute of Entomology)

THE very interesting collection of Chrysomelidae made by the Ruwenzori

Expedition, 1934-5, is represented by 78 species of which 53 have previously

been described. The remaining 23 species are unfortunately represented mostly by

single specimens, but when there is a series I now describe them. I have already

described 7 species from this collection in the Aunals and Magazine of Natural

History, and references to these are included below. Among the subfamilies the

Sagrinae are not represented, and the Eumolpinae and Clytrinae are very poorly

_tepresented; as a rule they are plentiful all over Africa.

The subfamilies are represented as follows.

Orsodacninae I species Chrysomelinae 4 species

Criocerinae 4 species Halticinae "15 species

Clytrinae 2 species Galerucinae 32 species

Eumolpinae 3 species Cassidinae II species

Cryptocephalinae 5 species Hispinae 2 species

All the Types of new species are in the British Museum (Natural History).

12. CERAMBYCIDAE

by EH. A. J. DUFFY

THE 106 specimens of Cerambycidae collected by the British Museum East

Africa Expedition comprise only 41 species, and include two species new to

science and one new aberration. The majority of these species are of no out-

standing interest as they are in general widely distributed and by no means rare.

The paucity of specimens from high altitudes (i.e. 7000 ft. and over) is disappoint-

ing but is no doubt due to the obvious impracticability of specialised collecting.

For the sake of completeness, a few specimens from Kenya collected by

A. J. F. Gedye in 1934 have also been included. The names of these species are

enclosed in square brackets.

CERAMBYCINI

Derolus bifarius sp.n. (Figs. 1, 2)

Female: Elongate, parallel-sided; head and thorax castaneous; elytra dark

brown to pitchy, with apical fourth light brown; abdomen dark brown. Head

slightly elongate, with eyes large, emarginate and coarsely facetted. Antennae

short, not extending beyond middle of elytra; first segment covered with rather

large and very small punctures, and short light grey pubescence; third and

fourth slightly nodose apically; fifth to tenth distinctly pectinate apically on

outer margin; eleventh segment longer than tenth, and with apical third

strongly sinuate on outer margin (Fig. 1); pubescence becoming gradually more

dense towards apices of antennae; third segment one and one-half times as long

as fourth, scarcely longer than fifth. Maxillary palp with third segment

broadened and truncate apically. Prothorax (Fig. 2) quadrate, with sides

strongly rounded and constricted just behind front margin; disc comprising a

pair of paramedian round, glabrous, slightly convex areas, behind which are

166 RUWENZORI EXPEDITION

three transverse grooves, the first two being incomplete medially. A deep

transverse impression present anterior to front coxal cavities, which are rounded

on their outer margins ; mid-coxal cavities narrowly open to epimera. Prosternal

process truncate apically. Elytra two and one-half times as long as combined

basal width; finely and densely punctate; apices truncate, with sutural angles

acutely spined; pubescence absent (due to rubbing?). Legs sparsely pubescent,

with femora slightly clavate, orange-yellow, with apices broadly black; femoral

carinae well-defined; tibiae orange-yellow, broadly black apically and basally;

tarsi dark brown. L.18 mm.; b. 4:5 mm.

The fact that the elytra are glabrous in this specimen is very probably due to

rubbing, as all other described species of this genus are densely pubescent. The

sculpturation of the pronotum, however, should adequately serve to distinguish

this species from all others of this genus.

Male: Elongate, narrow, subparallel-sided; head, thorax, and abdomen

reddish brown. Head quadrate, distinctly broader than prothorax, longitudinally

sulcate between antennal tubercles; occiput, vertex, and frons finely granulose.

Maxillary palpi with third segment very elongate and slender. Antenna (Fig. 3)

about one-third longer than body; first segment enlarged apically, slightly

curved, and slightly longer than third segment; rugose, punctured, and bearing

a few long outstanding setae; remaining segments covered with short yellowish

pubescence; third and fourth segments entirely pale testaceous, each bearing a

few very long subapical setae (which merge together apparently to form a single

slender spine) ; fourth segment shorter than fifth, and fifth slightly shorter than

sixth; fifth segment with at least apical half black, basal part testaceous; apical

halves of remaining segments brown to fuscous. Eyes large, deeply emarginate,

and coarsely facetted ; very closely approximated above, less closely on underside

of head. Prothorax about one and one-half times as long as broad, and constricted

at base and apex; hind margin much narrower than front margin; sides swollen

and bluntly tuberculate medially; rather sparsely punctured and finely golden

pubescent, giving various effects due to irregular contour. Scutellum reddish

brown, strigose, and rounded apically. Elytra (Fig. 3) with scattered suberrect

setae, and rather coarse punctures on basal two-thirds; brown, with testaceous

markings as figured. Abdomen with first segment as long as second and third

together. Legs with femora (lig. 3) each strongly clavate, testaceous, bearing

numerous long, bristle-like setae, and tibiae with a broad black band at middle

and apex (the hind legs are missing in this specimen). L. 9 mm.; b. 2 mm.

species.

13. CARABIDAE*

Deux Peryphus nouveaux du Ruwenzori oriental.

par P. BASILEWSKY

Musée du Congo Belge, Tervuren

Mon excellent collégue et ami Mr. Everard B. Britton, du British Museum

(Natural History), vient de me soumettre six Bembidiinae recueillis par la

British Museum East African Expedition, sur le versant oriental du Mont

Ruwenzori. Ces individus appartiennent a deux espéces différentes, toutes deux

nouvelles, ce qui n’a rien d’étonnant quand on connait l’endémisme de ces

insectes sur les hauts sommets de l'Afrique Orientale, et quand on considére

qu’aucun représentant de ce groupe n’était connu de I|’Est du Ruwenzori.

Cette découverte souligne encore la grande différence faunistique qui existe entre

les versants belge et britannique de ce massif montagneux, différence qui a

déja été observée pour d’autres groupes de Carabiques; en effet, sur le versant

occidental du Ruwenzori on ne connait que le Peryphus (Hypsipezum) ruwen-

zoricus Alluaud, espéce recueillie jusqu’a 4200 metres d’altitude et tres différente

des deux formes décrites ci-dessous. Je remercie donc Mr. Britton pour la

communication de ces intéressants spécimens.

Peryphus buxtoni sp. n. (Fig. 1)

Long. 3,8-4,2 mm.—Apteére. Dessus bronze foncé, avec de trés légers reflets

verdatres sur la téte, les élytres un peu brunatres par transparence vers l’apex,

ainsi qu’a la suture; mandibules et palpes d’un brun trés foncé, le dernier

article de ceux-ci testacé; antennes d’un brun noiratre, le premier article

ferrugineux; pattes ferrugineuses un peu rembrunies aux genoux; dessous

d’un brun de poix foncé.

Téte large et peu convexe, pourvue d’une forte microsculpture, consistant en

éléments plus ou moins carrés; yeux gros mais modérément saillants; tempes

légérement rétrécies; sillons frontaux peu profonds mais trés larges, délimitant

au milieu une convexité longitudinale bien marquée. Dent labiale forte.

Antennes longues et fines, atteignant le tiers basilaire de I’élytre, le troisieme

article un peu plus long que le suivant. Pronotum nullement transversal, aussi

long que large, subcordiforme, relativement peu convexe, a largeur maximale

tres fortement déportée en avant du milieu; bord antérieur faiblement concave,

les angles antérieurs appuyés contre le cou, les cotés largement arrondis en avant,

puis rétrécis en ligne fortement sinuée devant les angles postérieurs qui sont vifs

et sub-aigus, mais non ou a peine saillants vers l’extérieur; base presque droite,

plus étroite que le bord antérieur; sillon longitudinal fin et profond; gouttiére

marginale un peu plus profonde en arriére qu’en avant; sillon transversal pos-

térieur indiqué et délimitant un aplanissement fortement ruguleux-chagriné,

Fic. 1.—Peryphus buxtoni sp. n.

tandis que le restant de la surface est pourvu de la méme microsculpture que la

téte; dépressions basilaires profondes et sub-arrondies.

Elytres trés ovoides et peu convexes, aplatis sur le disque, l’épaule complete-

ment effacée, apex arrondi séparément; repli basilaire absent, le repli latéral

terminé au niveau de la 5e strie par un tubercule assez distinct; gouttiere

marginale profonde sur toute sa longueur; striole scutellaire courte et oblique;

pore basilaire a l’origine de la deuxiéme strie; les trois stries internes fortes et

ponctuées, continuées presque jusqu’a l’apex; stries 4 a 7 plus faibles progressive-

ment, terminées plus en avant; strie 8 assez forte, plus ou moins paralléle a la

gouttiére, confondue avec elle seulement en avant; intervalles plans, a micro-

sculpture aussi forte que celle de l’avant-corps, mais consistant en éléments

différemment conformé et la striation autre de l’élytre. En outre, P. jeanneli

est ailé.

Peryphus edwardsi sp. n.

Long. 3,8 mm.—Aptere. Dessus d’un verdatre métallique foncé trés brillant,

les pattes et les antennes ferrugineuses, ces derrié€res avec les articles 2 4 11 plus

ou moins tachés de brun foncé; palpes bruns foncés, le dernier article testacé;

dessous noir.

Espeéce voisine de P. buxtoni, mais en différe par des caractéres trés nets.

Tete nullement rétrécie en arriére, mais pourvue de la méme microsculpture et

des mémes sillons frontaux. Pronotum nettement transverse et un peu plus large

que long, un peu moins cordiforme par suite du moindre élargissement de la partie

antérieure ; cOtés aussi sinués devant les angles postérieurs qui sont plus aigus

et bien plus. saillants; dépressions basilaires moins profondes et plus étendues;

microsculpture du dessus un peu moins forte, ce qui rend la surface plus brillante.

Les élytres sont un peu moins ovoides et l’épaule est moins effacée, mais le

contour général est presque le méme; par contre, P. edwardsi présente une forte

convexité sur le disque, convexité tout a fait absente chez l’espéce précédente ;

striation de l’élytre semblable, mais les trois stries internes sont plus fortement

ponctueés.

(F’. W. Edwards), 2 ex. Holotype au British Museum, paratype au Musée du

Congo Belge a Tervuren.

Cette espece différe aussi de P. jeanneli Alluaud de l’Aberdare, par les mémes

caractéres que la précédente, a savoir: taille plus faible, coloration autre, pro-

notum autrement conformé, striation différente de l’élytre et absence d’ailes.
