Length of body, 3 mm.
Length of wing, 3-5 mm.
This species is about the size of C. cvbaria Etn., but the grey abdomen of the
¢ of the latter will separate it from C. edwardst.
BAETIDAE
Centroptilum spp.
Three species of this genus are represented in the collection; two from
Ruwenzori, Namwamba Valley, 10,200 ft., and one from Kenya, Thika, 4500 ft.
All are females and in rather poor condition and therefore I shall do no more
than record the presence of the genus in these districts. Other records of the
genus on the African continent include Algeria, Sudan, Belgian Congo, and
South Africa.
MYRMELEONIDAE
Nemoleon notatus (Rambur)
Myymeleon notatus Rambur, 1842, Ins. Névr.: 406. Walker, 1853, List Neur. Ins. B.M.

EPHEMEROPTERA AND NEUROPTERA I09Q
Macroleon quinquemaculatus (Hagen)

Formicaleo quinquemaculatus (Hagen) 1866, Stett. Ent. Zeit. 27: 405.

Myrmeleon vapax Kolbe, 1897, Deutsch. Ost-Afrika, 4, Netzfl.: 20.
UGANDA: Ruwenzori, Kilembe, 4500 ft., 1 g; Masaka, 1 9.
Distribution—East, South, and West Africa.
There are in the British Museum collections three examples of this species
labelled by W. F. Kirby as having been part of Walker’s series of Myrmeleon
lethalis. This must have been an error on the part of Kirby or a predecessor, as
two of the examples entered the Museum after the publication of Walker’s
Catalogue, and all three disagree entirely with Walker’s description of /ethalis,
which is a Formucaleon (Banyutus Navas).
ASCALAPHIDAE
Helicomitus festivus (Rambur)
Bubo festivus Rambur, 1842, Névropt.: 356.
Ascalaphus festivus (Rambur), Walker, 1853, List. Neur. Ins. B.M. 2: 419.
Encyoposis (?) festivus (Rambur), McLachlan, 1871, J. Linn. Soc., Zool. 11: 264.
Helicomitus festivus (Rambur), van der Weele, 1907, Notes Leyden Mus. 28:153.
1908, Coll. Zool. Selys., 8:175.
UGANDA: Masaka, 2 8.
Distribution —Throughout tropical Africa and Madagascar.
I suspect that at some future date it may be necessary to divide this species
into several species or sub-species. Examination of examples from different
parts of Africa has revealed differences in the vestiture of the extreme base of
the costa of the anterior wings of the males. Some are clad only with very short,
fine setae; others with longer black setae, directed basally, and some have a
large tuft of silky hairs, directed basally. The material in our collections at
present is insufficient to decide the value of this character as a specific distinc-
tion, but it seems to me to be worthy of mention.
NEMOPTERIDAE
Nemopistha imperatrix (Westwood)
Nemopteva imperatrix Westwood, 1867, Tr. Ent. Soc. Lond. (3) 5:507.
Halter imperatrix (Westwood), Kirby, 1900, Ann. Mag. N.H. (3) 6: 460.
Nemopistha imperatvix (Westwood) Navas, 1910, Mem. R. Ac. Ci. Barc. 8 (18) :13.
Navas, 1912, Gen. Ins. 136: 13.
UGANDA: Budongo Forest, 7.11.35, I ¢.
The type of this species is a female, labelled “‘W. Africa.’’ There are other
IIo RUWENZORI EXPEDITION
females in the British Museum collections from Ashanti and Gold Coast. This
male appears to agree reasonably with them in body colouration and also in
colouration of the hind wings. In particular it has the deep cream apex
and a paler transverse band across the centre of the brown area before the apex
of the wing.
HEMEROBIIDAE
Hemerobius nairobicus Navas
Navas, 1910, Brotéria, Zool., 9:78.
UGANDA: Ruwenzori, Bwamba Pass (West Side), 5500-7500 ft., i.35, I 3g.
Previously recorded only from Nairobi, the type locality.
This example from Ruwenzori agrees with one in the British Museum from
Nairobi, determined by Dr. Nathan Banks. To Navas’ description I would add
that the anal plates of the male are each armed witn a short spur on the dorsal
margin, rather before mid-way.
Hemerobius elatus Navas (Fig. 2)
Navas, 1914, Voyage Alluaud et Jeannel Afr. Or., Névropt. : 30.
Kenya: Aberdare Range, Mt. Kinangop, 8000 ft., x.34, I 3.
Fig. 2.—Hemerobius elatus Navas. 3. (a) wings. (b) tenth sternite and parameres,
lateral.
The abdomen of the male type is missing, but I have little doubt that
Dr. Edward’s specimen is conspecific. The wings are narrower than in H. evvans,
and the inner and outer gradates in the anterior wing are farther apart.
Distribution.—Mt. Kenya.
EPHEMEROPTERA AND NEUROPTERA TT
Hemerobius errans Navas (Fig. 3)
Navas, 1914, Voyage Alluaud et Jeannel Afr. Or,, Névropt.: 31.
Esben-Petersen, 1920, Ann. S. Afr. Mus., 17: 508.
UGANDA: Ruwenzori, Nyamgasani Valley, 6400 ft., xii.34-1.35 (D. R.
Buxton), 1 3.
Fig. 3.—Hemerobius evrans Navas. 3. (a) apex of abdomen, lateral. (b) ninth
sternite, ventral. (c) tenth sternite, parameres and hypandrium, lateral. (d) ditto,
from behind. (e), parameres from above.
As the g genitalia of so many African species are as yet unfigured, I am using
the example of H. errans taken by Mr. Buxton to make good one of the omissions.
Distribution.—Kenya (Mt. Kinangop), Cape Town, Orange Free State.
Notiobiella ugandensis sp. n. (Fig. 4)
UGANDA: Budongo Forest, 7.11.35, I ¢.
3. Head yellowish, with brown markings:—a spot in the centre of the labrum;
the genae; a triangular patch on each side of the vertex, adjoining the eyes;
terminal segments of maxillary and labial palpi. Antennae yellowish. Pronotum
parabolically produced in front, yellowish, with obscure brownish markings
(possibly the result of decomposition). Meso- and metanota yellowish, with
brownish spots at wing bases. Legs yellowish.
Abdomen yellowish. Ninth tergite short, apical margin of ninth sternite
with a broad shallow excision. Anal plates large, with apices incurved, dilated
112 RUWENZORI EXPEDITION
and truncate. A group of g—1o trichobothria on the basal half of each anal plate.
Tenth sternite large, narrow above, its lower angles curved inwards towards
each other. From the lower half of each apical margin extends a long finger-like
process directed upwards and in the example before me, crossing its fellow.
Fig. 4.—WNotiobiella ugandensis sp. n. $ (a) wings. (b) apex of abdomen, left
lateral. (c) right anal plate from behind. (d) special margin of ninth sternite. (e)
tenth sternite, aedeagus and parameres from side. (f) aedeagus from above.
(g) parameres from above.
Aedeagus in the form of a convex plate, attached by its basal angles to the tenth
sternite and supporting a large membranous structure, the lower part of which
appears to be an eversible tube. Apex of the convex plate with a deep rounded
excision, the resulting lateral angles each armed with three short, stout teeth.
Parameres with a slender fused stem and somewhat quadrate apical flanges.
Wings with neuration and pattern as in figure. Veins yellowish-green, the
cross veins between the first and second branches of the radius, the medius and
EPHEMEROPTERA AND NEUROPTERA ET3
cubitus, and the branches of the cubitus in anterior wing dark brown. Ptero-
stigma in both wings yellowish.
Length of anterior wing, 6:5 mm.
Length of posterior wing, 5 mm.
This species is obviously related to my N. hargreavest from Sierra Leone,
but the form of the anal plate differs from that of any Notiobiella known to me.
From NV. decora Kimmins (Uganda) it differs in its less elongate wings.

I take this opportunity of figuring the male genitalia of this species.
Distribution.—Kilimandjaro, Abyssinia, Natal.

2. Head greenish-yellow, immaculate; labrum and clypeus creamy-white.
Apical segment of maxillary palpus annulated about mid-way with fuscous.
EPHEMEROPTERA AND NEUROPTERA II5
Antennae yellow, longer than anterior wings, basal segment unmarked, dilated
on its inner surface. Pronotum broader than long, narrower in front than
behind, anterior margin rounded; in colour yellowish, without brown markings.
Meso- and metanota yellowish, the former with indications of a pale, fuscous
transverse band. Legs yellowish, apical segment of tarsi not darker than pre-
ceding segments; tarsal claws strongly dilated at their bases. Abdomen
yellowish-green. Wangs hyaline, spotted with brown as in fig. Venation green-
ish, gradate cross-veins and some other cross-veins brown, particularly within
the brown spots. Stigma indistinct.
UcanpDA: Masaka, type 2 and I paratype (with abdomen damaged).
I have been unable to reconcile these specimens satisfactorily with any of
the described African species, and I have deemed it better to describe them as
new rather than risk an incorrect distribution record due to an error in deter-
mination.

In a cleared example the claspers of the ninth tergite appear less broad at
the base than in Esben-Petersen’s figure, and they carry, each on its inner surface
towards the base, a short finger-like projection terminating in a tuft of setae.
Inner apical surfaces armed with about a dozen short, black spines.
