LcConte.] BARmi. 'ZSl 



California, locality unknown; several specimens, without sexual difter- 

 ences. 



RHOPTOBARIS n. g. 



The single species of this genus resembles closely in form, sculpture and 

 pubescence TricJiobaris trinotata, but without the three denuded spots at 

 the base of the prothorax. It diifers by the club of the antennae almost as 

 long as the funicle, elongate-oval, entirelj^ pubescent, and very indis- 

 tinctly annulated; the first joint of the funicle is as long as the three fol- 

 lowing, and stouter; 2-7 short, gradually a little broader. Beak as long as 

 the head and prothorax, curved, not very slender, depressed as usual at 

 tip, frontal constriction not deep. Front cox* moderately distant, prester- 

 num not impressed nor sulcate. Elytra elongate oblong, separately rounded 

 at tip; pygidium exposed, obliquely declivous. Last ventral segment as 

 long as the third and fourth united, rounded at tip, with a slight tooth at 

 the middle in (^, as in Trichobaris. Legs slender, tibiae with a very small 

 apical hook; third joint of tarsi moderately dilated, bilobed; last joint long, 

 claws rather large, divergent. 



1. R. canesens, n. sp. 



Oblong elongate, very densely and rather finely punctured, and clothed 

 with brownish gray pubescence, or hair-like scales. Head finely punc- 

 tured; beak not stout, finely punctured, nearly smooth at the tip. Protho- 

 rax scarcely longer than wide, gradually but not strongly narrowed from 

 the base, sides broadly rounded, base broadly subsinuate, truncate in front 

 of the scutellum. Elytra a little wider than the prothorax, strite well 

 marked; interspaces wide, flat, denselj" and rugosely punctured. Punctures 

 of under surface a little coarser than above. Length 4 mm.; .16 inch. 



Colorado, four specimens. 



TRICHOBARIS n. g. 



I have separated as a distinct genus, certain species of elongate form and 

 densely clothed with scales or pu])escence. They difter from other genera 

 of the group by the following characters: Club of antennae rather small, 

 oval, entirely pubescent, first joint forming about one-half of the mass. The 

 funicle is stout, first joint longer, others equal in length, but gradually 

 broader. Beak as long as the prothorax, much curved, rather stout, quite 

 gil^bous at base, frontal constriction deep. Elytra separately rounded at 

 tip. Pygidium vertical; last ventral segment scarcely longer than the 

 fourth; with a small apical cusp in \j^. Front coxa3 very narrowly sepa- 

 rated, prosternum broadly concave, and subsulcate in front of the coxtv. 

 Legs slender, tibia? with moderate apical hook; tarsi with third joint mod- 

 erately dilated, bilobed, last joint long, claws approximate and connate at 

 base.
