very delicately punctured; the petiole distinctly punctured. 

 Mandibles in part, antennae beneath, tegulae, knees and tibiae partly 

 rufo-fuscous ; a dot between the antennas, a line behind the (^y<^, 

 hind border of prothorax, post-scutel and border of .segment 1st, 

 2d, yellow ; the rest of the abdomen, even the lamellar edge of 

 2d segment, quite black. Wings cloudy. 



Bess. a. diff — Resembles very much E. Santa-Anna and lasvis, 

 in the form of its petiole, but this is parted by a groove at the 

 end, and the thorax is shagreencd ; the petiole is also shorter.

?. This insect is exactly like the E. mexicanus, and only 

 differs from it in certain characters. 



The clypeus is less flattened, and is not shining but dull; there 

 is hardly any frontal carina. The punctuation of the body is 

 apparently the same or a little more dense. The scutellum is a 

 little less strongly cribrose. The antennas are scarcely ferrugi- 

 nous beneath. The clypeus and the scutels are entirely black ; the 

 segments 3-5 have their borders delicately ornamented with yel- 

 low above and beneath. 



This species may be but a variety of the E. wexicanus. In 

 both species the 2d cubital cellule of the wing is quite large, tra- 

 peziform, with straight borders; the radial border is large.
