"wider, parabolic at tip, widest at basal %, the sides more rounded at base, the 

 bumeri rather evident ; impressions at the base almost obsolete ; inner fovea 

 distinct ; subsutural impressions rather distinct, the suture feebly elevated to- 

 ward base but not beaded. Legs slender, the femora feebly clavate, the an- 

 terior only just visibly more strongly. Length 1.25 mm. ; width 0.6 mm. 



Iowa (Iowa Citj^). Mr. Wickham. 



The single type before me is probably a female, but the species 

 can be readily distinguished from perforatus by its more oblong 

 elytra, with more basally exposed humeri, obvious subsutural im- 

 pressions with elevated suture, and smaller and still sparser ely- 

 tral punctures; the head is larger than in per/bra^MS, and the 

 prothorax is less swollen anteriorly and less narrowed at base.

Moderately stout, rather feebly ventricose, polished, impunc- 

 tate anteriorly, the el3^tra distinctly and rather closely punctate ; 

 body pale rufo-testaceous throughout, the legs and antennse con- 

 ■colorous; pubescence abundant, short and inconspicuous an- 

 teriorly, pale fulvous, coarse, moderate in length, suberect, strongly 

 recurved and very conspicuous on the elytra. Head transverse, 

 the eyes rather large and prominent, nearl}^ twice as long as the 

 tempora ; fourth joint of the maxillary palpi ^ as long as the 

 third but slender and finely aciculate. Antennae rather less than 

 ^ as long as the bodj^ gradually incrassate ; second joint much 

 shorter and narrower than the first, feebly obconic, ^ longer than 

 wide, \ longer than the third and distinctlj^ thicker ; third and 

 fourth equal in width, ^ and ^ longer than wide, the next two 

 just visibly thicker, ^ longer than wide and quadrate ; seventh 

 and eighth nearly ^ thicker than the sixth, almost equal and sub- 

 globular ; ninth ^, the tenth |-, thicker than the eighth, ^ and ^ 

 wider than long respectively ; eleventh barely as long as the two 

 preceding, ogival. Prothorax not as long as wide, nearly ^ wider 

 than the head, strongly dilated and laterally rounded in apical 

 half, the sides strongly convergent and distinctlj'^ sinuate thence 

 to the base ; surface slightly uneven and indefinitely rugulose 

 transversely near the base, and with one or two minute tubercular 

 setigerous punctures at the sides and less basal. Scutellum dis- 

 tinct, rounded at tip. Elytra elongate-oval, ^ longer than wide, 

 between two and three times as long as the prothorax and fully | 

 wider, widest at basal f but with the sides broadly and evenly 

 .-arcuate throughout ; humeri somewhat visible at base ; subhu-
