534 RHYNCHOPHORA. 
The insect upon which this genus is based is one of the numerous species included 
under Celosternus by Schonherr, but which cannot be retained in it if C. compernis 
(Germ.) is to be taken as the type. . | 
C. longipennis is a narrow, elongate form, superficially resembling a patch of bird’s 
excrement.

Of this species we have received thirteen specimens, two only of which are males. 
The rostrum differs thus in the two sexes: in the male it is rugosely punctate and 
feebly carinate to about the middle, and thickly punctate thence to the apex; in the 
female it is very much smoother, and broadly bisulcate in front of the basal constric- 
tion, the two grooves elongate-triangular in shape, densely squamose, and separated by 
a smooth, outwardly widened, raised space. The head is canaliculate between the 
eyes, and sometimes has a longitudinal carina on the vertex. The white scales on 
the elytra are rounded and imbricate. 
ATRICHIS. 
Atrichis, Chevrolat, Ann. Soc. Ent. Fr. 1882, p. 55. 
Chevrolat gives Celosternus delumbis (Germ.), Boh., as the type of this genus, and 
includes various other species in it, one of which, A. albitarsus, Chevr., cannot, 
however, be treated as congeneric. The name Africhis is here retained for a few 
species nearly allied to C. delumbis, which are chiefly characterized by their strongly 
transverse, rather prominent eyes (a peculiarity noticed by Lacordaire *, but not 
mentioned by Chevrolat); the short, curved, stout rostrum, which is widened and 
usually depressed at the base; the ovate or elongate, compact, antennal club; the 
rather short, stout legs, with more or less clavate, uni- or bidentate femora; the 
horseshoe-shaped mesosternum ; and the unequal length of the intermediate ventral 
segments of the abdomen, 2 being a little longer than 8 or 4. The anterior tarsi are 
similarly formed in the two sexes,
