distinctly longer than wide, the base and apex subequal in the male, the former 

 relatively narrower in the female ; sides feebly arcuate, convergent and straight 

 toward base ; punctures rather small, feeble, remote and unevenly distributed. 

 Scutellum densely pubescent. Elytra oblong, at base almost twice as wide as 

 the prothorax, nearly two and one-half times longer, three-fifths longer than 

 wide, not distinctly wider behind the middle than at base, the sides subparallel ; 

 striae broadly, rather strongly impressed, coarsely, deeply and not very closely 

 punctate ; intervals convex, minutely, sparsely and unevenly punctate. Legs 

 rather short and stout, the femora strongly toothed ; tibiae bent toward base. 

 Length 5.0 mm. ; width 1.9 mm. 



Arizona. 



The two specimens before me represent one of the most distinct 

 species of the genus, recognizable at once by the numerous coarse 

 recurved white setae of the upper surface, the subparallel elytra, 

 relatively narrow prothorax, large eyes and large femoral teeth. It 

 does not appear to be at all closely allied to any of the Mexican 

 species.

Black, polished, narrowly, feebly subcuneate, bristling with long 

 coarse erect and blackish setae, with a few short paler subrecumbent 

 hairs interspersed. Head and beak coarsely closely and unevenly 

 punctate ; eyes separated by three-fourths of their own width ; beak 

 rather slender, not quite as long as the prothorax, confusedly, lon- 

 gitudinally sulcate and rugose, with an elongate feeble impression 

 in the middle between the antennae, the latter long, the second 

 funicular joint barely one-half as long as the first ; basal joint of 

 the club long and evenly obconical, with the sides straight. Pro- 

 thorax but slightly longer than wide, the sides sinuate behind the 

 apex and more broadly before the base, the apex broadly arcuate 

 and scarcely wider than the base; disk very coarsely, densely punc- 

 tate. Scutellum small, pubescent. Elytra at base three-fifths wider 

 than the base of the prothorax, two and one-half times longer, not 

 quite twice as long as wide, slightly wider behind the middle than 

 at base, the humeri narrowly rounded ; disk with feebly impressed 

 series of coarse, rather close-set punctures. Legs slender, the femora 

 very long, the tooth small. Length 4.2 mm. ; width 1.6 mm. 



Pennsylvania to Texas. A well-marked species which cannot 

 fail of recognition by reason of the sparse dual vestiture, coarse 

 sculpture and long slender feebly toothed femora. It does not 

 appear to be abundant.
