9. This species differs from E. fraternus: By the clypeus 

 being less bidentate, much less notched ; by its smaller size, and 

 a little shorter petiole; also in the part of the same enlarged and 

 so much divided by an obsolete channel ; by its finer punctures, 

 especially on the abdomen; by its more ferruginous pile, which 

 is longer and gives the insect a sub-woolly appearance. Also by 

 a more complete marking ; the clypeus often presenting two yel- 

 low spots, the wing scale bordered with yellow and having a red 

 dot in the middle ; and the abdomen shining upon the quite wide 

 borders of segments 2-5 ; that of the 2d being scalloped and its 

 lateral spots often lengthened ; finally by the transparent wings, 

 slightly washed with ferruginous along the side. It is fitting to 

 add that the yellow border of the prothorax, in place of being 

 enlarged at its two extremities as in the E. fraternus, is narrow 

 and is at times bi-interrupted. 



Var. a. Clypeus black, or with two yellow marks at the sum- 

 mit; no subalary spot. 



b. The yellow band of the post-seutel interrupted. Scute! 

 black. 



c. Clypeus yellow, bordered with black below and marked with 

 a black trident. 



(1. Prothorax black, or only with a little Yellow in the middle.
