 All the specimens we have answering to the description are from 

 Texas and are small and slender.

Length 14 mm. = .45 inch. Hab. Texas near Mexican boundary. 

 The pubescence is distinctly mottled.

Length and Habitat same as villosum. 



These common species differ markedly in the form of prothorax as 

 well as in parallelum being usually much more slender. The 5th ventral 

 segment in ^ villosum is rounded at tip, while in $ parallelum it is 

 truncate. 



E. pumilum Newn. Ent. p. 29; Lee. J.A.P. ser. 2, II, p. 14. 

 Length 9 mm. = .36 inch. Hab. Georgia, Tex.

 E. aculeatum Lee. S.M.C. No. 264, p. 184. 

 Length 15 mm. = .60 inch. Hab. Texas. 



These two species are closely allied and distinguished from other 

 species by their very slender form. 



E. unicolor Rand. Bost. Journ. II, 1838, p. 42. 

 Length 11 mm. = .45 inch. Hab. Atlantic States. 



The slender scarcely pubescent body and elytra distinguish this 

 species at once. 



E. moestum Lee. Proc. Ac. Phil. VI, p. 442. 

 Length 13 — 15 mm. = .50 — .60 inch. Hab. Texas. 



Resembles spurcum in size and robust form, but differs in elytral 

 spines and pubescence which is sparse, exposing the dark brown color 

 of the body and elytra.
