Length 10.5-15.6 mm. 



Head moderately produced, its median length varying from less than 

 half to more than eight-tenths interocular width and from three- 

 tenths to one-half transociilar width, anterior margin broadly rounded 

 or truncate in dorsal aspect, without carina at transition from crown to 

 face, ocelli located on a line between anterior angles of eyes, each about 

 equidistant between adjacent eye angle and median line of crown, 

 crown without median fovea, without longitudinal keel laterad of 

 each ocellus, with or without an M -shaped elevation bordering 

 posterior margin, without pubescence, lateral clypeal sutures extending 

 onto crown and attaining ocelli; antennal ledges protuberant in 

 dorsal aspect, each with a longitudinal depression and carinate dors- 

 ally in lateral aspect, anterior margin usually steeply declivous, oc- 

 casionally {E. inflata, new species, E. fowleri (Distant), E. proxima 

 (Melichar)) with a shallow concavity; cl>-peus usually convex (ex-

 portion granulate; transclypeal suture almost always incomplete; face 

 finely pubescent below; clypellus not produced, its contour continuing 

 profile of clypeus. 



Thorax with pronotal width less than transocular width of head, 

 lateral margins parallel, surface rugose or rugose and punctate, disc 

 without pubescence, posterior margin concave, in lateral aspect with a 

 complete dorsopleural carina which is oblique posteriorly and arched 

 slightly downward in anterior half; scutellum transversely striate in 

 posterior portion. Forewing translucent or hyaline, occasionally with a 

 sclerotized area along costa in region of anteapical cells, with four 

 apical cells, the base of tlie fourth more proximal than base of third, 

 claval veins fused through a considerable portion of their length, 

 separate basally and apically, without an anteapical plexus of veins and 

 without supernumerary anteapical crossveins to costal margin; wings of
