moderately sparse but very conspicuous, confusedly arranged on 

 the elytral intervals. Beak differing greatly in the sexes, very 

 slender, just visibly but evenly arcuate and three-fifths longer than 

 the prothorax in the female, stouter, much shorter and distinctly 

 arcuate near the base and apex in the male, the antennal club in 

 the female scarcely perceptibly shorter than the entire funicle, but 

 not much longer than the preceding six joints in the male. The 

 prothorax is small, conical, truncate at apex and very feebly con- 

 stricted anteriorly, the punctures scarcely more than one-fourth as 

 wide as the scutellum and separated by barely one-half of their own 

 widths. Elytra abruptly fully two-fifths wider than the prothorax, 

 two and one-half times as long as the latter, one-third longer than 

 wide ; sides parallel and straight, the apex broadly and abruptly 

 rounded, the striae deep ; intervals three to four times as wide as 

 the striae, finely and feebly, not very densely, confusedly and sub- 

 asperately punctate. Fifth ventral segment longer than the pre- 

 ceding two combined, acutely rounded in the female, a little more 

 obtuse in the male. Anterior coxae separated by nearly one-fourth 

 of their own width. Length 2.8-3.8 mm.; width 1.1-1.65 mm. 



California ; Texas ; Nebraska (Pine Ridge). In the extensive 

 series before me the largest and smallest specimens are both females. 



2 Orthoris cylindrifer n. sp. — General form as in crotchi, but polished 

 and more sparsely setose, the setae moderately long, stiff, erect and bristling 

 on the beak and pronotum, but recurved on the elytra, forming a nearly even 

 single line on each interval. Head coarsely punctured, setose, the transverse 

 impression narrow, strong and impunctate, the beak moderately densely 

 punctate, rather slender, strongly arcuate at base and near the apex, some- 

 what short, scarcely more than one- third longer than the prothorax in the 

 female ; antennae long, the first funicular joint robust and as long as the next 

 three, two to seven small, subequal, club very long, fully three times as long 

 as wide, one-half as long as the prothorax and fully one-third longer than the 

 entire funicle, abruptly wider than the seventh funicular joint, the sides 

 straight and subparallel or very feebly divergent thence to apical third, then 

 gradually pointed, indistinctly annulate, the basal joint longer than wide. 

 Prothorax small, nearly one-half wider than long, the sides convergent from 

 the base, feebly but distinctly arcuate, very obsoletely constricted near the 

 broadly truncate apex ; base with a small but distinct median lobe ; disk 

 rather coarsely and not densely punctate, the punctures almost one-third as 

 wide as the scutellum and very deep. Scutellum moderate, transversely sub- 

 quadrate. Elytra abruptly one-half wider than the prothorax, nearly as in 

 crotchi, except that the intervals are polished, quite distinctly convex and 

 each with a single uneven series of small subrugulose feeble and rather dis-
