much sparser punctuation, narrower, more convex form and much 

 shorter third antennal joint. 



I have dedicated it to Prof. C. V. Riley of Washington, as a 

 slight token of my appreciation of his many acts of kindness and 

 liberality. 



E. liitidllS n. sp. — Rather slender, convex and subcylindrical, black 

 throughout and strongly shining, glabrous. Head rather sparsely punctate, 

 moderately coarsely so toward apex ; antennse robust, nearly as long as the 

 head and prothorax, the third joint four times as long as wide and fully as 

 long as the next two together, last three joints distinctly dilated forming a 

 club, the ninth and tenth strongly transverse. Prothorax quadrate, very nearly 

 as long as wide, the apex transverse, broadly and feebly bisinuate, equal in 

 width to the base, which is broadly, rather strongly arcuate ; apical angles 

 right, narrowly rounded, basal broadly obtuse and not prominent but not at 

 all rounded; sides parallel, very feebly arcuate; disk just visibly wider at 

 apical third than at base, evenly convex, extremely minutely and sparsely 

 punctate. Elytra two and three-fourths times as long as the prothorax, and, 

 in the middle, nearly one-half wider, about twice as long as wide ; sides 

 broadly arcuate ; base broadly emarginate ; humeri right, not noticeably ex- 

 posed ; apex acutely rounded ; disk obliquely declivous behind, having feebly 

 marked, distant, completely unimpressed series of extremely minute punc- 

 tures ; intervals minutely, sparsely and more or less confusedly punctate, the 

 punctures not distinctly larger or denser laterally. Femora all slender and 

 completely unarmed ; spurs of the anterior tibiae very unequal, the anterior 

 slender, acutely pointed and moderate in size ; posterior tarsi slightly com- 

 pressed, nearly three-fourths as long as the tibiae. Prosternum slightly pro- 

 longed but not at all reflexed, the apex vertical. Length 18.0 mm. ; width 

 6.7 mm. 



Arizona. 



This species, which is represented before me by a single speci- 

 men, apparently a male, belongs near longicollis, but differs in its 

 flatter, rather shorter prothorax, less rounded on the sides, in its 

 shorter, broader elytra, broadly and rather strongly emarginate at 

 base and having widely distant rows of punctures, and in its shorter, 

 stouter and much more clavate antennse. 



E. c*o ill posit us n. sp. — Moderately robust, convex, intense black 

 throughout, the pronotum dull and strongly alutaceous ; elytra shining, very 

 feebly alutaceous, glabrous. Head densely dull, finely, rather sparsely punc- 

 tate ; antennae rather long and stout, fully as long as the head and prothorax, 

 third joint between three and four times as long as wide, outer joints slightly 

 broader, the ninth and tenth somewhat transversely oval. Prothorax about 

 as long as wide, the apex and base equal in width, the former broadly, very 

 feebly emarginate, the latter correspondingly arcuate ; apical angles right,
