narrower at base, the elytral apex more obtusely rounded and its 

 smaller size. It differs from impiitm Csy. in its form and the color 

 of its legs. 



Amara edax new species. 



Form rather short, broad and convex. Color black with an extremely 

 feeble metallic lustre, legs black ; tibiae and tarsi dark rufo-piceous, three basal 

 joints of the antenna rufo-testaceous, outer joints fuscous. Head and thorax 

 smooth, strongly shining, very finely alutaceous in the basal angles ; elytra very 

 finely alutaceous but shining. Head scarcely one half the width of the thorax, 

 slightly narrower than the apex ; strioles scarcely apparent ; antennae not quite 

 reaching the base of the thorax; third joint strongly carinate on basal third. 

 Thorax one half wider than long, just perceptibly narrower than the elytra, - 

 widest one third before the base, sides strongly and evenly rounded, apex 

 about one half the width of the base, strongly emarginate, apical angles nar- 

 rowly rounded ; basal angles rounded, rather strongly bent back ; puncture 

 nearly twice as far from the side as from the basal margin ; median line fine, 

 distinctly impressed ; anterior transverse impression feeble, basal impressions 

 and fovese altogether obsolete, basal area impunctate, surface evenly convex. 

 Elytra one third longer than wide, sides evenly arcuate from about the middle 

 to the apex, apical sinuses distinct. Strias fine, impunctate ;. the scutellar with 

 an ocellate puncture at base, not joined to the first at apex; punctures of the 

 eighth stria with three wide intervals at middle ; elytral interva.ls alrnost flat. 

 Length, 7.35 mm. ; width, 3.5 bb. (^. One specimen. 



This species is probably close to A. lanrana Csy. described from 

 Boulder Co., Col. The form is broader, the elytra shorter, the thorax 

 distinctly wider before the base with the sides more evenly arcuate, 

 the hind angles rounded, punctures nearer the basal margin. 



Cercyon incrematus new species. 



Form oval, widest near the base of the elytra, moderately convex. Color 

 black, side margins of the thorax rather broadly and indefinitely dark rufous; 

 elytra dark rufo-piceous, apical third and broad side margins rather indefinitely 

 obscure testaceous ; antennae, mouth parts ani legs rufo-piceous. Head mod- 

 erately closely and somewhat finely punctate, about one half the width of the 

 thorax. Thorax more than twice a^ wide as long, sides more strongly arcuate 

 and narrowed in front ; basal' marginal line extending to the fourth elytral 

 stria, surface moderately closely and somewhat finely punctate, scarcely less 

 closely on the sides. Elytra not quite three times the length of the thorax, 

 one third longer than wide, widest at basal fourth where they are distinctly 

 wider than the thorax, thence narrowed and feebly arcuate to about apical 

 third, thence acutely rounded to the apex ; ten striate, striae not closely punc-
