158 AMERICAN COLEOPTERA. 



a little at the middle, rather finely, moderately, closely punctate; basal fovea 

 linear, reaching nearly to the middle. Elytra widest behind the middle; humeri 

 rather prominent ; intervals convex. Beneath moderately punctate. Length 2 

 mm. ; .08 inch. 



Hab. — Florida. 



Described from a single male in the collection of Mr. Ulke. This 

 species may be distinguished from every other in our fauna by the 

 yellow front coxse. It bears a remarkable resemblance to the Euro- 

 pean assimile, a female of which is before me ; and were it not for 

 the fact that this latter is said to have the front coxse of the male 

 denticulate at the apex, I should scarcely feel warranted in de- 

 scribing our species as distinct. Among our own species anripes 

 looks much like opacicolle, agreeing well in the general form and 

 feebly curved beak, with the antenme inserted far from the base ; 

 but the pale legs and unarmed tibise forbid a close approximation. 

 Its relationship with its present associates seems even more I'emote. 

 It is certainly a rather aberrant form, and its position in a cabinet 

 arrangement may be left to the judgment of those who may be 

 fortunate enough to obtain examples. 



75. A. cavirr4»iiK Lee. — Robust, black ; pubescence fine, plentiful, clothing 

 the beak throughout in the % , but wanting beyond the insertion of the 

 antennae in the 9; prosternum and anterior coxse especially densely clothed; 

 infra-ocular fringe long and conspicuous. Beak rather strong, feebly curved, 

 slightly tapering, scarcely at all dilated, barely longer than the prothorax {%), 

 a little longer but scarcely as long as the head and prothorax ( 9 ) ! surface finely 

 strigose and moderately punctate ( %) ; sculpture less pronounced ( J ). Antennfe 

 piceous or piceo-testaceous, two basal joints pale, first joint very little longer than 

 the second, outer joints not transverse. Front more or less canaliculate and 

 carinate at the middle, and either depressed from side to side between the eyes 

 or with a well-marked juxta-ocular depression ; eyes moderate. Prothorax wider 

 than long, or occasionally as long as wide; sides divergent to the middle, thence 

 parallel to the base; apical and basal sinuations rather feeble; surface closely, 

 strongly punctate; basal impression linear. Elytra about cme-third longer than 

 wide, broadest behind the middle; stride wide; intervals but little wider than 

 the strife, nearly flat. Beneath strongly, rather closely punctate; legs slender, 

 first tarsal joint more than twice as long as wide, equal to the next two; claws 

 witli a moderately strong tooth. Length 2-2.5 mm. ; .08. 10 inch. 



Hab. —Pacific Coast, from British Columbia to Southern Cali- 

 fornia. 



The sutural angles are slightly rounded in the male, but the dif- 

 ference is not very obvious. A strongly- marked species, and with 

 the exception of the one which follows, not at all closely related to 

 any other. It seems to be comuion throughout the region in which 

 it occurs.
