out and coxse pale flavate ; autennje brownish-testaceous, paler toward base ; 

 head and pronotum moderately shining, densely and strongly grannlose and 

 granulato-reticulate respectively ; abdomen polished, reticulate. Head almost 

 as wide as the prothorax ; eyes moderate, setae very short ; antennal promi- 

 nences verj' strong ; suture feebly impressed ; surface very sjjarsely and not 

 distinctly punctate, vertex not tuberculate, having a somewhat elongate im- 

 pressed median fovea ; antenna rather slender and elongate ; second joint 

 longer and slightly more robust than the third, four to six subequal and sub- 

 moniliform, six to nine very gradually more robust and transverse, nine and 

 ten equal, about one-third wider than long, eleventh ovoidal, distinctly shorter 

 than the two preceding together. Prothorax slightly narrower than the base 

 of the elytra, one-fourth wider than long ; sides in anterior two-thirds parallel 

 and straight, then strongly arcuate and moderately convergent to the basal 

 angles, which are obtuse, not rounded, and minutely prominent ; lateral angles 

 entirely obsolete, broadly rounded, apical right, very narrowly rounded ; base 

 and apex just visibly arcuate ; disk somewhat coarsely feebly very sparsely 

 and somewhat unevenly punctate, the pubescence rather long and stout ; 

 median groove extremely fine and feebly impressed. Elytra slightly shorter 

 than wide, about one-half longer than the prothorax, and, toward apex, nearly 

 one-third wider ; sides slightly divergent, broadly feebly arcuate, very feebly 

 emarginate at apex, the inner angles slightly rounded ; disk impressed on the 

 suture behind the scutellum, somewhat coarsely but feebly and sparsely punc- 

 tate, the punctures distant by from two to three times their own diameters, 

 closer and smaller than those of the pronotum ; pubescence fine, sparse and 

 moderate in length. Abdomen mucli narrower than the elytra, slightly wider 

 than the prothorax, finely, very sparsely punctate, much more densely so and 

 densely pubescent beneath toward the sides. Length 4.5 mm. 



Nevada. 



The bypomera are distinctly narrowly impressed near the margin, 

 and are rather wider than the distance thence to the coxse, the coxal 

 fissures being narrowly open and short. The mentum is broadly 

 feebly impressed. The anterior angles of the epistoma, at least in 

 the male, are finely and feebly tuberculate. It is closely allied to 

 lectus, but differs in its more slender form and smaller more trans- 

 verse prothorax. 



The prosternal sutures are obliterated and the mentum is mar- 

 gined at apex with a very thick convex bead — hypoglottis — sepa- 

 rated by a fine deep groove.
