faintly mottled with pale brown on the elytra ; beak ( ^ ) curved down- 

 ward beyond the middle, rather stout, gradually thicker basally; prothorax 

 rather longer than wide, moderately narrowed at apex, finely, very densely 

 punctate throughout ; scutellum narrow, densely pubescent, pale brown ; 

 elytra three-fifths longer than wide, somewhat strongly narrowed from the 

 moderately prominent humeri to the apex, the apices individually rounded; 

 striae but little more than a fourth as wide as the flat intervals, strongly 

 and very closely punctate at the bottom, the intervals finely, closely punc- 

 tate ; fifth male ventral feebly impressed, with the apex moderately sinuate 

 and briefly, sinuately beveled. Length, (^,8.0-8.5 mm.; width, 3.2-3.8 

 ram.; Length of rostrum, (^ , 5.4 mm. Types without locality-label, but 

 probably from Indiana. 



Resembles caryatrypes Boh., as usually identified in our collections, 

 but smaller, less stout and more acuminate, with slightly coarser elytral 

 striae, much shorter legs and shorter beak ; in the species mentioned the 

 fifth ventral of the male is truncate medially at tip. 



B. cyluidricollis n. sp.— Moderately slender, piceous-black throughout 

 the body and beak, the legs slightly paler; vestiture dense, almost uniform 

 in colour and pale gray ; beak ( $ ) rather thick but almost filiform, but little 

 thickened basally, straight, becoming very gradually and extremely feebly 

 bent beyond the middle ; prothorax much longer than wide, scarcely three- 

 fourths as wide as the elytra, parallel, very moderately narrowed apically, 

 densely punctate ; scutellum concolorous ; elytra one-half longer than 

 wide, the oblique sides arcuate ; apices each rounded, the humeri well 

 exposed, rounded ; striae about a fourth as wide as the intervals, with the 

 punctures moderate, each bearing a pale scale, the intervals not quite flat, 

 very finely, not very densely punctate. Length, $,7.5 mm.; width, 3.0 

 mm.; length of rostrum, $, 9.4 mm. Tennessee. 



Differs from the female of caryatrypes in its much smaller size, more 

 slender form, uniform vestiture, shorter and nearly straight beak, apically 

 unconstricted prothorax and in general facias to a very striking degree. 



** First fimiatlar Joint longer than the second except in cimeatus. 



^Beak extremely slender, filifonn, not at all enlarged basally, the antenncB 



( ^ ) inserted behind the middle ; pygidium ( ^ ) excavated. 



B. cuneatus n. sp. — Form moderately stout, piceous-black, the beak 

 and legs dark testaceous ; antennae long and very slender, the first and 

 second funicular joints long and as nearly as discernible perfectly equal 

 in length, each a little shorter than the third and fourth combined ;
