Detroit, Michigan, 1 ; Lee County, Virginia, 3. 



The foiirtii joint of the ijiaxillary palpi is moderately robust and 

 much longer than the first two together ; the tarsi are very slender 

 with the second and third joints much elongated. The under sur- 

 face of the head is covered densely with long erect setae, which are 

 dilated at tip. 



15. E. capitullllll n. sp. — Form somewhat robust. Pubescence fine, 

 short, evenly distributed, rather close, pale fulvo-cinereous, color throughout 

 reddish-testaceous or ferruginous ; legs and antennae scarcely paler. Head 

 small, as wide as long; eyes large, moderately prominent ; genae prominent, 

 acutely rounded, much smaller tlian the eye ; posterior margin broadly 

 truncate and sinuate ; interocular surface highly polished and impunctate, 

 having two rounded impressed spongy-pubescent foveae on a line with the 

 middle of the eyes, connected by an anteriorly arcuate parabolic impressed 

 channel of nearly equal depth throughout ; intermediate surface entire, 

 rather strongly convex ; supra-antennal tubereulations elongated, promi- 

 nent, connecting ridge wide, somewhat prominent and lower in the middle ; 

 clypeus strongly rounded anteriorly ; antennae short, slender, scarcely more 

 than one-third longer than the head, joints eight to ten equal in length, 

 increasing uniformly in width, the latter twice as wide as long, eleventh 

 much wider than the tenth, very robust, slightly longer than wide, conoidal, 

 obtusely acuminate ; last joint of the maxillary palpi robust, not twice as 

 long as wide, scarcely as long as the two preceding joints together; sub- 

 capital sensitive setae rather short and sparse. Prothorax widest at the 

 middle where it is about as wide as long and much wider than the head ; 

 sides thence rather less convergent anteriorly than posteriorly, very strongly 

 arcuate in the former, distinctly sinuate in the latter direction ; apex about 

 three-fifths as long as the base and much less than one-half the pronotal 

 width, nearly transverse, base broadly arcuate ; disk strongly convex, shin- 

 ing, impunctate, having at one-fourth the length from the base a transverse 

 posteriorly arcuate narrow groove, terminating at the sides in deep circular 

 spongy foveae, and coalescent with the anterior limit of a very deep longi- 

 tudinally oval medial impressed pit which nearly attains the basal margin 

 and is slightly spongy-pubescent at the bottom. Elytra at base slightly 

 wider than the pronotum ; sides moderately divergent posteriorly and strongly 

 arcuate ; together transversely truncate behind ; disk as long as wide, nearly 

 one-half longer than the prothorax, rather strongly convex, shining, im- 

 punctate ; sutural striae distinct, close, nearly straight, lateral distinct, 

 narrow, terminating at slightly more than one-half the length posteriorly; 

 humeri jirominent. Abdominal segments distinctly narrower than the 

 elytra ; sides parallel ; surface very strongly convex, highly polished and 

 impunctate ; first three segments decreasing uniformly in length ; first dorsal 

 having at the base two very short robust parallel earinae. Legs long and 

 slender; prosternal foveae large, transversely oval. Metasternum large, 

 h<aving on each side at its anterior border a transverse strongly pubescent 

 fovea. Length l.f) mm.
