Female , forma brachyptera . — -Apparently identical with the 
macropterous form except for the following: Legs much paler, 
the tibiae, tarsi, and distal portions of femora lemon yellow; 
ocelli wanting; wings reduced, the fore pair represented by a 
pair of small oval brown pads, each with two rather long, nearly 
pointed bristles. 
Described from three females taken by Mr. C. B. Williams 
at Caura Valley, Trinidad, British West Indies, April 20, 1916, 
by sweeping grass. 
Very close indeed to E. harti, but readily known by the 
italacized characters.
