very delicately punctured; the petiole distinctly punctured. 

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

 rufo-fuscous; a dot between the antennae, a line behind the eyes, 

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

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

 2d seo-ment, quite black. Wings cloudy. 



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

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

 end, and the thorax is shagreened ; the petiole is also shorter. ^

9. 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 antennae 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. mexicanus. In 

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

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