B. mollii n. subsp, — Smaller ihan ihe smallest of a very large series 

 of ihe preceding, resembling it in general characters, but with the 

 antennn> inserted evidently beyond the middle of the very short beak, 

 the second funicular joint relatively shorter and only a little longer than 

 the third, the prothorax smaller, ^horter and more finely punctate and the 

 elytral strine very coarse, fully half as wide as the intervals. length, ^, 

 4 9 mm.; width, 1.9 mm.; length of rostrum. 2.4 mm. 



The single type is without locality label, but is probably from 

 Arizona. 



B. stri^oins, n. sp. — p'orm and coloration nearly as in auri^er but 

 rather shorter, the vesliiure nearly similar; beak (9) shorter, similaily

 stouter club ; prothorax nearly as long as wide, more gradually though 

 slightly narrowing anteriorly, with the basal angles more obtuse, the punc- 

 tures a little smaller and less densely placed, and with a strikingly broad 

 smooth impunctate median line, which is two or three times as wide as the 

 fine impunctate line o{ auriger, though likewise not extending much before 

 the middle ; elytra more abbreviated than in aurt^er but similar in general 

 form and sculpture, not about twice as long as the jiroihorax as in that 

 species, but much less. Length, 9.52 mm ; width. 2.:! mm.; length of 

 rostrum, 9 > 4.8 mm. Arizona. 



The legs are shorter than in auriger, especially the femoral peduncle. 



B. a/i^onqtiinui n. s|). — l-orm somewhat as in <i«//j,v/- but shorter and 

 stouter, the ty|)e pale brownish-testaceous in colour throughout ; l>eak 

 (f^ ) stout, strongly arcuate, the antennae inserted at the middle, the first 

 three funicular joints decreasing uniformly and rapidly in length; prothorax 

 of the same general form as in auriger, not cpiite as long as wide, the 

 parallel sides gradually roimding and converging before the middle, the 

 l)unctures smaller, close but not crowded, the pale vitl.x narrow; scutellum 

 short, solidly squamose on the elevated part ; elytra rapidly cuneiform, 

 with arcuate sides and distinct humeri, much less than one half longer 

 than wide and not twice as long as the prothorax, the condensations of 

 pale fulvous scales numerous and indefinite, the striae less than half as 

 wide as the intervals, the latter finely and sparsely punctate, only 

 slightly rugulose. Length, <J , 6.0 mm.; width, 2.7 mm.; length of 

 rostrum, (J, 3.0 mm. Indiana. 



The fifth ventral of the male is feebly impressed and scantily clad, 

 gradually feebly deflexed apically, the apex feebly sinuate, the cleft between
