NORTH AMERICAN COLEOPTERA. 13 



42. E. neTadeiisis. — Black, pubescence brown, longer than usual, sub-erect 

 on the prothorax, which is a little longer than wide, narrowed from the base for- 

 wards, bright red finely not densely punctured, red, posterior spine black. Elytral 

 interspaces convex, rugosely punctured. Antennae longer than prothorax, sleuden 

 joints elongate, 2d and 3d united equal to the 4th; 7 mm. 

 Nevada; one specimen in Dr. Horn's collection. 



47. E. affinis. — Black with yellow pubescence. Antennae but little longer than 

 prothorax strongly serrate in the male, 3d joint but little longer than 2d ; protho- 

 rax a little longer than wide, more narrowed in front and rounded on the sides 

 from the middle, deeply densely punctured, angles unicarinate. Elytra scarlet, 

 apical third black, strife punctured ; 7-8 mm. 



Washington Territory and Southern California. This species exactly 



resembles E. cordatus, except that the pubescence of the prothorax is 



not erect but inclined. 



48. E, obliquus Say. The name areo/atus is really the older name but as it 

 applies to a rather rare variety and the other name has come into such general 

 use it is not thought necessary to make the change.
