Barin^e 385 



arcuate, with bristling vestiture above behind the antennae, which 

 are at the middle, the club much shorter than the funicle; prothorax 

 nearly as in the preceding but with the punctures narrowly though 

 evidently separated and distinctly coarser; elytra shorter, oblong, 

 much wider than the prothorax and distinctly less than three times 

 as long, the interstitial punctures small, uniserial on many of the 

 intervals; abdomen finely, sparsely punctulate. Length (9) 3.3- 

 3.5 mm.; width i. 35-1. 4 mm. Colorado (Colorado Springs). 



tenuirostris n. sp. 



Body very much smaller and more slender, black, rather shining, the 

 elytral hairs subuniserial; beak in the female virtually straight, 

 nearly half as long as the body, pubescent and bristling above behind 

 the antennae, which are at the middle, the club not quite as long as 

 the funicle; prothorax bristling with long sparse hairs, only a little 

 wider than long, the sides feebly converging and broadly arcuate; 

 apex two-thirds as wide as the base; punctures moderate and rather 

 well separated; elytra parallel, nearly three times as long as the 

 prothorax and about a third wider; interstitial punctures fine, con- 

 fused. Length (9) 2.6 mm.; width 0.9 mm. California (locality 

 unrecorded) angustula n. sp. 



5 — Pronotal punctures notably coarse and almost in mutual contact. 

 Body stout, moderately shining, black; beak in the female two- 

 fifths as long as the body, slightly thickened and notably bristling 

 toward base, the antennae near the middle, the club slightly shorter 

 than the funicle; prothorax fully a third wider than long, the con- 

 verging sides broadly arcuate; apex fully half as wide as the base; 

 elytra oblong, a fourth wider than the prothorax and evidently less 

 than three times as long; striae rather coarse; intervals not quite 

 flat, the fine punctures confused, rather strong and somewhat more 

 close-set than usual, the squamules in about two irregular series. 

 Length (9) 3-5 mm.; width 1.6 mm. California (locality unre- 

 corded) robustula n. sp. 



Pronotal punctures everywhere distinctly separated; body not so 

 stout 6 



6 — Integuments more shining, the pronotal punctures rather coarse and 

 deep; beak ( 9 ) nearly two-fifths as long as the body, almost straight, 

 the upper surface curving rapidly upon the head at base, or (cf ) 

 very little shorter and somewhat more evidently arcuate; antennae 

 at the middle (9), a trifle beyond (cf), the beak in both sexes in 

 great part with very bristling pubescence; prothorax small, nearly a 

 third wider than long, the converging sides arcuate; elytra more 

 gradually rounded behind than usual, two-fifths wider than the 

 prothorax and distinctly more than three times as long, the humeri 

 rather prominent; interstitial punctures confused and well separated 

 though rather strong. Length (cf 9) 3.6-3.8 mm.; width 1.35-I.4 

 mm. California (Ontario). Three specimens captiosa n. sp. 



Integuments only moderately shining, deep black, the size smaller than 

 in captiosa; beak rather thick, slightly but evidently arcuate, slightly 

 longer than the prothorax {(^), distinctly so (9 ), almost similar in
