One specimen, from New Mexico, in the collection of Mr. 1'lke. 

 Allied to E. granulata and humeralis, but differs by the mucb 

 stronger sculpture of the elytra. The outer spur of the front 

 tibia? of the male, as in those species is enlarged, as long as the 

 first three joints of the tarsi, and obtuse at tip. The under sur- 

 face is punctured, and the prosternum is not prolonged behind.

A unique specimen, from Colorado Territory, given me by 

 Dr. S. Lewis. Differs from the preceding by the liner sculpture 

 both of thorax and elytra, and by the humeri nol being prominent. 

 It seems to be more nearly related to E. inculta, but the thorax 



is more rounded on the side-, the antenna' are less elongated and
