Iowa (Iowa City). Mr. Wickham. 



The shorter and stouter form of the body, with the prothorax 

 inflated and widest behind the middle, and smaller head, will dis- 

 tinguish this species from ochreatus. The single specimen before 

 me has the sixth ventral rather longer than the preceding three 

 combined when measured along the median line, and is doubtless 

 a male. 



11. Eu. cruralis n. sp. — Stout, the hind body strongly inflated, polished 

 and impunctate, pale rufo-ferruginous throughout, the legs and antennae con- 

 colorous; pubescence sparse, short and coarser on the bead, long, erect and 

 bristling on the elytra. Head behind the antennae scarcely visibly wider than 

 long, the eyes well developed but not prominent, the sides strongly conver- 

 gent, broadly and evenly arcuate to the neck, which is }4 ^^ wide as the head ; 

 upper surface convex and broadly tumid behind, minutely, sparsely punctu- 

 late, except in the middle toward base, more distinctly punctate on the 

 median prolongation of the front. Antennse rather more than ^4 ^^ long as the 

 body, the club long, slender and feebly incrassate; basal joint long, cylindric, 

 more than twice as long as wide, a little longer than the next two and much 

 thicker, excavated above at apex but not grooved; second obconic, a little 

 longer than the fourth but not thicker, % longer than wide; third and fourth 

 }4, fifth scarcely %, sixth }^, longer than wide; seventh not quite as long as 

 wide, the upper twice as long as the lower side; eighth also very oblique at 

 tip, much wider than long; ninth distinctly shorter than the two preceding 

 and only }-^ wider, a little longer than wide; tenth still thicker, similar in 

 form, slightly elongate; eleventh long, not thicker than the tenth, not quite 

 as long as the two preceding, gradually and obliquely pointed. Prothorax 

 narrow, scarcely ^5 wider than the head, slightly elongate, the sides parallel 

 and broadly rounded, widest at the middle; apex much narrower than the 

 base; disk finely rugulose near the basal margin and with two small and 

 feeble subbasal foveae at each side. Elytra ^3 longer than wide, twice as long 

 as the prothorax and fully twice as wide, widest at the middle, strongly and 

 obliquely narrowed to the base of the prothorax, broadly rounded behind ; 

 humeri and basal impression nearly obsolete; subsutural impressions feebly 

 visible near the base. Pygidium triangular, much wider than long, sparsely 

 punctulate and minutely, transversely reticulate toward base. Legs stout, the 

 femora strongly and abruptly clavate, the posterior with an obtusely triangu- 

 lar tooth on the outer edge near the trochanter; basal joint of the hind tarsi }4
