reflexed. The thorax is broader, sides more stronglj rounded, apex deeply emarginate 

 with acute angles, base trisinuate also with acute angles. The elytra arc also more 

 acutely margined than siduralis, the dorsum slightly concave, longer and more parallel 

 and in the males slightlj produced, their surface is also feeblj sulcate with striae of coarse, 

 closely placed punctures. The anterior femora (if the male are armed with a rather small 



acute tootll. 



This species has thus far occurred in Texas alone. Length 1.25—1.50 inch. 



Section EI. of Group [. contains all those species of the sub-genus Eleodes in which 

 the anterior spur of the anterior tibia is notably longer, broader, thicker and more stronglj 

 curved than the posterior '-pur. in the females.

The peculiar form of the elytra distinguishes this and the nexl from the others ofthi 

 tion which follow. The sides are sub-parallel, very feebly rounded and scarcely nar- 

 rower (frequently broader) at base than at any other portion. The base is also truncate 

 and the angles rectangular, extending under the basal angles of the thorax. In both 

 species the middle lobe of the mentum is smaller, rather more acute and more pi'omii 

 in front than the species in the preceding section. The form of the thorax of E. pedi- 

 noides is similar to that of acuta. The anterior angles are not acute and the posterior are 

 rectangular. The base feebly emarginate and with an impression near each hind angli . 

 The sides are rounded anteriorly, slightly sinuate posteriorly. The elytra are oval, not 

 narrowed at base, black, glabrous, and never pubescent, feebly sulcate with moderately 

 convex interstices. The stria? are rather coarsely punctured in some specimens, less evi- 

 dentlj in others. la the variety asperata the punctures become slightly muricate al tin- 

 sides near the ap x. The elytra are also moderately convex, margin rounded, the humeri 

 are occasionally slightlj carinate. The femora are mutic in both sexes. 



Occurs in southwestern Texas. Length .75—95 inch.

Similar in form to pedinoides, differing in the following characters: Elytra usually 



flattened, margin more acute, alternate interspaces more elevated, the shallow sulci are 

 rather strongly muricately punctured, each puncture with a short robust hair in recent 

 specimens. The elytra are never shining as in pedinoides, and the peculiar sub-tricosta- 

 tion will readily distinguish it. The variety robusta, as the name indicates, is larger, 

 stouter and rather more coarsely muricate. 



The species is abundant on the plains of Kansas and Nebraska and southward into 

 T< xas. Length .50-.90 inch.
