equally distributed punctures, much more distant than the length 

 of their diameters ; lateral edge rectilinear from near the anterior 

 angles to the tip of the posterior angles, which are piceous and 

 rather short : scutel oval : elytra striate, the striae punctured : 

 feet pale rufous. 



Length less than one-fifth of an inch.

11. E. AURiPiLis. — Above with dense golden hair; clypeus 

 emarginate ; antennae black. 



Inhabits Arkansa. 



Head covered with golden hair : clypeus emarginate : antennae 

 black; basal joint rufous : thorax convex, rather narrower at the 

 base, covered with golden hair ; a dorsal indented line ; posterior 

 angles [173] very short, not excurved, but complying with the 

 curve of the lateral edge : elytra less densely covered with golden 

 hair, excepting at the base ; with punctured striae : beneath 

 black, covered with very short prostrate somewhat silvery hair : 

 feet dull rufous. 



Length two-fifths of an inch. 



I have seen but a single specimen, which was brought from the 

 Arkansa by Mr. Thomas Nuttall. The hair is much more yellow 

 and less dense than that of E. pennatus Fab.
