and evident, the fifth segment (cf ) with the feeble apical sinus 

 narrower than usual, about a third as wide as the base; femora with 

 the minute punctulation feeble and not dense. Length (cf ) 22.0 

 mm.; width 8.4 mm. Arizona (locality unrecorded). 



constricta n. sp. 



Body more parallel, the anterior parts more developed, the surface less 

 polished; antennae fully three-fourths as long as the body, the dense 

 pubescence pale chocolate-brown; prothorax fully three-fourths as 

 wide as the elytra in the male, more transverse than in the preceding 

 and not subbasally constricted, nearly similarly and coarsely, deeply 

 punctate but with the minute close punctulation stronger; scutellum 

 sharply triangular, with rather distinct pubescence, which is parted 

 along the middle, much more acutely angulate and less transverse than 

 in constricta; elytra oblong-oval, nearly twice as long as wide, convex, 

 the line of flexure much more obtuse than in the preceding, the 

 punctures coarse, sparse, extending behind the middle both suturally 

 and externally, those on the flanks not differing but those along the 

 line of flexure crowded and rugose basally; fifth ventral (cf ) very 

 much broader at apex, the barely at all sinuate truncature more than 

 half as wide as the base; femora with the minute punctulation very 

 strong, dense and conspicuous. Length (cf ) 24.0 mm.; width 9.3 

 mm. Utah (locality unrecorded) uteana n. sp. 



5 Spine at each side of the prothorax subhorizontal, though slightly 

 oblique as usual, unusually long, slender and subparallel, one-fourth 

 as long as the thoracic length; surface very shining; antennae gradu- 

 ally tapering as usual, the minute dense vestiture plumbeous- 

 bluish; prothorax nearly as long as wide, having rather small and 

 widely scattered punctures, with some coarser intermingled an- 

 teriorly and close and very coarse near the basal margin; elytra 

 convex, oval, very broadly obtuse at apex, the coarse punctures very 

 sparse, irregularly subserial to somewhat behind the middle, coarse 

 and asperate on the flanks and rather closer there basally than above; 

 lateral line of flexure obtuse, coarsely, closely punctate; punctula- 

 tion of the shining femora fine, not dense, with some fine punctures 

 rather sparsely intermingled and several coarser and very remote; 

 hairs on the strongly and closely punctulate abdomen gray and ex- 

 tremely minute, scarcely visible. Length (9) 26.5 mm.; width 

 10.4 mm. Arizona (Tugson), Snow pimalis n. sp. 



Spine at the sides of the prothorax shorter, rapidly acuminate and ex- 

 tending more upward in obliquity, not more than a fifth or sixth 

 as long as the thoracic length 6 



6 Prothorax but slightly wider than long and much narrower than the 

 elytra in the male, relatively smaller (9 ); surface shining; antennae 

 fully two-thirds as long as the body, with dark grayish vestiture, 

 the four basal joints stout, those beyond abruptly much more slender; 

 prothorax with very few small or moderate punctures but with 

 many very coarse punctures scattered near the base; scutellum 

 notably pubescent, with broad glabrous line; elytra strongly convex, 

 oval, nearly twice as long as wide, with moderately acute and distinct 

 line of flexure basally, the punctures coarse, sparse, extending in
