JORDAN—COLEOPTERA: ANTHRIBIDA 257 
granulated, transversely ovate, bemg widest above. The antennal fovea is smaller than 
the eye, which it touches, triangular, rounded dorsally, the dorsal edge being rather more 
dorsal than the inner edge of the eye. The labiophore, on the under side, is flat, apically 
only one-fifth wider than proximally, with the lobes rounded off. The mandibles bear 
a tooth near the apex. The distal part of the labium is broad, non-divided, being broader 
than the mentum; the latter is exposed and on a level with the under surface of the 
labiophore. 
The antenna is slightly longer in the g than in the ?, and does not reach the base of 
the prothorax in either sex; segments 1 and 2 are incrassate and of about the same 
length, 2 being somewhat claviform, 3 is slender, slightly shorter than 2 and as long as 5, 
4 being a little shorter, 5—8 are thicker, 8 being the shortest of them; the club is 
moderately compressed, 9 and 10 triangular, asymmetrical, 9 surpassing 3 somewhat in 
length, 10 broader than long, 11 rounded. 
The prothorax is much longer in the $ than in the $, cylindrical above, with the base 
constricted, the dise:swollen and the apical margin projecting as a hood on to the head. 
The carina is remote from the base at the sides and gradually incurved, being nearest to 
the base in the centre; its lateral angle is distinct and projects a little as a tooth in 
a dorsal aspect ; below this projection the carina is bent backwards a very little and then 
runs forward almost to the centre of the sides, this lateral branch being less elevated than 
the dorsal carina. The short basal longitudinal carina is vestigial and joins the dorsal 
carina in an acute angle. The elytra are emarginate from shoulder to shoulder, and bear 
rows of minute punctures, not stripes, the punctures being more distinct in the basal area; 
the suture is not depressed, but the basal callosities and the depression behind them are 
marked. The pygidium reminds one of Basitropzis, inclining forward in the ¢, and being 
vertical in the ?. 
The prosternum is about as long as the head and rostrum together, the antecoxal 
portion being remarkably long. The mesosternal process is narrower than the intercoxal 
process of the cylindrical abdomen. The legs do not differ much in size among themselves, 
and also do not exhibit any obvious sexual difference. The hind tibia bears on the 
slanting dorsal apical surface a number of bristles. The first tarsal segment is as long as 
the claw-segment or a little longer ; the teeth of the claws are long. 
The underwings (of C. colydiopsis) have some characteristics which are apparently 
only found in the Anocerinz. The portion from the apex of the cell outward is half as 
long again as the proximal portion, 7.e. the cell reaches to two-fifths of the wing. The 
anal area is strongly reduced, as are also the anal veins, and there are no veins between 
the cell and the anterior anal vein (which usually reaches down to the base in Anthribide, 
but does not do so in the present genus). Moreover, the recurrent vein starting from the 
lower cell-angle is very short and feebly developed. The edge of the wing bears a fringe 
consisting of bristles placed at regular intervals and being at least six times as long as the 
hairs situated on the surface of the wing; the fringe-bristles of the anal lobe are three 
times as long as those of the apical portion of the outer margin.
