. 





Elongate, depressed, moderately shining, the rostrum opaque in the J , black or piceous, the shoulders 

 or basal portion of the elytra, antennae, tarsi, and base of the femora more or less rufeseent ; very finely 

 and sparsely pubescent, the prothorax and elytra also somewhat thickly clothed with decumbent, 







ochreous setae, those on the elytra uniseriately arranged down each interstice, the under surface with an 

 extremely fine sericeous pubescence. Head densely, minutely punctate ; rostrum ( c? ) usually as long as 

 or longer than the head and prothorax, almost straight, parallel-sided to near the tip, and densely 

 strigoso-punctate, ( $ ) slender, arcuate, not longer than the prothorax, shining, and almost smooth. 

 Prothorax broader than long, somewhat rounded at the sides, abruptly constricted in front, broadly 

 depressed down the middle of the disc ; densely, shallowly punctate, the narrow interspaces alutaceous. 

 Elytra elongate, much wider than the prothorax, punctate-striate, the interstices feebly convex, densely, 

 minutely punctate, and each with a row of larger, asperate, setigerous impressions. Beneath very 

 densely, minutely punctate. Metasternum deeply sulcate down the middle for the apical two-thirds of 

 its length. Legs elongate ; femora in both sexes strongly clavate and very sharply dentate. 

 Length 3~4|, breadth 1-lf millira. ( tf $ .) 



Hab. Panama, Bugaba, Tole (Champion). 



Numerous examples, males predominating, the latter varying greatly in size and in 

 the length of the rostrum. Immature examples are entirely ferruginous. This species 

 is separable at once from N. uniformis by its setose elytra.

mediate coxae exserted, each separated by at least one-half their own width ; first ventral suture sinuate, 



elytra elongate, not or very slightly wider than the prothorax, produced at the tip : anterior and inter-

 pair stout at the base ; tibiae rounded and unarmed at the outer apical angle ; tarsi pilose beneath, the 

 third joint strongly bilobed, the anterior pair dilated and with long projecting hairs in the $ , the claws 

 long and divergent; body elongate, subcylindrical, coriaceous, very finely pubescent, testaceous.

Type, H. attalece. 



- 



The two immature-looking insects belonging to this genus are nearly related to 

 Hoplorrhinus, from which they differ in their somewhat widely separated, anterior and 

 intermediate coxae, the more feebly pedunculate femora, and the deep, laterally-placed 

 rostral scrobes of the male, the anterior tarsi, too, being dilated and very hairy in 

 this sex. Sphceracus, Faust, from Brazil, seems to approach Hoplorrhinoides in many 



of its characters.
