Idaho ; "V^'yoniing. 



One of the smallest species of the genus and quite isolated ; it is 

 somewhat allied to pimelioides although very much smaller. In 

 jnmelioides the sides of the prothorax are arcuate, and only sinuate 

 for a short distance before the basal angles, and the sculpture of the 

 elytra consists of rounded flattened tubercles which are generally 

 arranged in very distinctly traceable approximate rows ; the legs 

 are black and the head very much smaller when compared with the 

 prothorax, w^hich is much more transverse ; the humeri are broadly 

 rounded. The species described by LeConte as viator does not 

 differ from pimelioides, the type being perfectly identical with the 

 ordinary males of that species.

E. lamiliatlliu n. sp. — Moderately robust, the male more slender, black 

 and dull througliout. Head small, very finely, sparsely and subasperately 

 punctate ; antennae slender, third joint from four to nearly five times as long 

 as wide, eighth one-half longer than wide. Prothorax about one-half wider 

 than long, the median portion very feebly convex, fully as long as wide, and 

 having two feeble, subparallel and sinuous impressions near the middle of the 

 disk ; side margins very widely and strongly reflexed, the outer edges parallel, 

 strongly and evenly arcuate throughout, the basal angles broadly rwouuded and 

 projecting beyond the transverse median portion of the base ; apex strongly 

 emarginate, the emargination not qiiite three times as wide as deep; surface 

 throughout finely, extremely sparsely and subasperately punctate. EJijtra 

 from one-half to four-fifths longer than wide, at base transversely truncate, 

 the sides very thin and broadly but not abruptly reflexed, the acute lateral 

 edges parallel and feebly arcuate in basal two-thirds, then rounded to the 

 apex and slightly prolonged, uniting in a prolongation of the suture ; humeri 

 rounded ; disk distinctly wider than the prothorax, each elytron broadly con- 

 cave, the suture elevated ; surface with approximate, imperfectly defined and 

 feebly impressed rows of rather coarse, impressed punctures, also finely and 

 sparsely asperate. Inflexed sides of the elytra nearly flat, somewhat coarsely 

 and sparsely but unevenly punctate, the epipleurse very imperfectly defined 

 except near the apex. Legs very slender. Length 14.0-15.0 mm. ; width 

 (j.8-7.5 mm. <

The elytral punctures referred to in the description are merely 

 impressed fovese, and do not appear to be in the least setigerous; 

 the finer but strong and sparse asperities are distributed over the 

 surface without regard to the punctures, and each bears a strong- 

 thick semi-erect seta — see third remark under Eleodes.
