10 Psyche [March- June 
Antennae 0.9 mm. long, reaching metasternum; segments 3-4 
equal in length, the latter a little broader; 5-10 each one-third 
longer than 4 and almost twice as broad as 3, broadest subapi- 
cally ; 11 one-half longer than 10, sides and apex rounded, broadest 
medially. Terminal segment of maxillary palpi enlarged, slender, 
three times as long as broad at widest point, ovoid, outer side 
somewhat less rounded than inner margin, broadest on apical 
half. 
Pronotum as long as broad (0.8 mm.), sides and apex rounded, 
base arcuate, midbasal lobe short, subtruncate. 
Elytra two and three-fourths times as long as broad (2.2 X 0.8 
mm.), sides subparallel to within a fourth of apex, then strongly 
curved, apices individually rounded. Anterior and intermediate 
tarsi longer than their tibiae. Posterior tibiae with two strong 
ridges (excluding subapical one), the anterior extending obliquely 
entirely across outer face; basitarsi with three, second segment 
with two oblique ridges. Anal style short, subtruncate at apex, 
but twice length of hypopygium (0.7 X 0.35 mm.). 
Length : to apices of elytra, 3 mm. ; to tip of anal style, 3.7 mm. 
Four specimens. Type, male, and two female paratypes, El 
Wuz, September 17, 1931, at light (Darling); a male paratype, 
Plain below J. Kaboija, J. Midob, N. E. Darfur, August 7, 1930, 
common on leaves of large succulent grasses (Michelmore) . 
This species is allied to diffinis Maklin (Acta Soc. Sci. Fenn. 10, 
1875, p. 586), but may easily be separated by the larger size, the 
much shorter anal style, the lighter appendages, the shorter and 
broader pronotum and elytra, and the elongate anterior ridge of 
the posterior tibiae. 
Mordellistena darfurensis new species 
Form elongate, sides subparallel; head, mouth parts, antennae 
(outer segments darker), pronotum, and anterior and intermedi- 
ate legs, flavo- or fuscocastaneous, thorax sometimes with an in- 
definite dorsal cloud; meso- and metasternum, abdomen, posterior 
legs, and elytra, black. Body densely covered with fine, recum- 
bent, flavo cinereous pubescence. 
Antennae 1 mm. long, reaching metasternum; segments 3-4 
equal; 5-10 each one-third longer than 4 and considerably 
broader, broadest subapically; 11 one-third longer than 4 and 
considerably broader; 11 one-third longer than 10, sides and 
apex rounded, broadest medially. Terminal segment of maxil-
