162 TERTIARY RHYNCHOrHOROUS COLEOPTERA. 



quartt'i-s ot" tlic glolx'. In tliu New World it is most aliundaut in the West 

 India islands, and onlv a couple of s|»(-cies occur in the United States east 

 of the Mississippi. Two species are found fossil in our Tertiaries — one at 

 Florissant, Colorado, the other at rireen River, Wyoming.

A single specimen, not very (dearly preserved, lying upon its side, 

 represents this species. It is clearly related very closely to Tropideres, if 

 it does not belong to the genus in the restricted sense in which it is used by 

 LeCoute. It seems to have been moderately stout, uniformly black, and 

 uniformly, densel}', an<l very delicately granulose, or shallowly punctate, it 

 is hard to say whicli. The beak is moderatel}^ stout, shorter than the head; 

 it is badly represented in the plate, having an appearance wholly unlike a 

 Tropideres; the antenna' not nmch longer than the beak, the club composed 

 of three subequal joints, fully twice as ])road as the preceding, together 

 forming an oval mass about two and a half times longer than broad; the 

 eye is round oval, entire, transverse, and moderateh' prominent. The pro- 

 thorax is largest, though but slightly, at the prebasal ridge, and tapers for- 

 ward remarkably little; the elytra have rather finely punctured strije, so 

 closeh' crowded as to give the strife the a|}pearance in the cast of nearly 

 continuous ridges.

A single specimen, in which, unfortunately, the antennae are not pre- 

 served, seems to belong here. The head is smooth, twice as broad as long, 

 with rather small, circular, prominent e}'es; the beak a little broader than
