J . Elongate, flattened, rather narrow, subopaque, almost bare ; black, the antennae and tarsi obscure ferruginous. 

 Head closely punctate, separated from the rostrum by a transverse groove, which is foveate in the middle ; 

 rostrum very feebly curved, rather slender, nearly as long as the prothorax, cylindrical, sparsely, 

 obsoletely lineato-punctate, the short, dilated basal portion coarsely punctured ; antennal club conico- 

 cylindrical, a little longer than joints 4-6 of the funiculus united. Prothorax longer than broad, rounded 

 at the sides, narrowed and constricted in front, truncate at the base ; coarsely, densely, uniformly 

 punctate. Scutellum prominent, transversely cordate, rather large, smooth. Elytra about one-fourth 



but not wider, than the prothorax, very gradually narrowing from the rounded humeri, sub- 

 truncate at the apex ; deeply punctate-striate, the interstices flat, not wider than the strise, and each 

 with a regular row of closely-placed, coarse, deep, oval or rounded punctures (fig. 11 b). Pygidium about 

 as long as broad, rounded at the tip, coarsely, closely punctate. Beneath very coarsely, closely punctate ; 

 first ventral segment hollowed down the middle. Legs rather short ; femora and tibiae coarsely 

 punctured, the tibise feebly sinuate within, toothed at the inner apical angle, and with the apical claw 

 rather short ; third tarsal joint broad, with a densely pilose space along the apical margin beneath. 

 Length 6J-, breadth 2i millim.

One male. 



This 



species agrees 



with C. setulosa 



in having largely 



developed, 



angularly ascending mesothoracic epimera and broad metathoracic episterna ; but the 

 antennal club is elongate, the scutellum is larger and transversely cordate, the 

 pygidium is shorter, and all the tibiae are toothed at the inner apical angle. The 

 large, ascending mesothoracic epimera, the less developed metathoracic episterna, the 

 transverse scutellum, the long antennal club, &c, separate C. mexicana from Metamasius 

 submaculatus and its allies.

The type of this genus is Sitophilus banonii, Guer., from Cayenne, a species ranging 



far 



as the Isthmus of Panama, whence I have
