Eight macropterous females and one undeveloped male are referred to this species, 
described from females only. In the undeveloped specimen from Cuernavaca the 
elytra reach the base of the sixth abdominal segment (in the undeveloped type they 
are stated to extend to a little beyond the middle of the abdomen), and the membrane 
is nearly as long as the clavus. The scutellum has a small pallid spot on each side, 
not mentioned by Reuter. The outer apical angles of the sixth connexival segment 
are rectangular in the male. 
A brachypterous male (fig. 24) and female have also been received from Omilteme 
(with developed forms) with the elytra barely twice the length of the scutellum and 
conjointly truncate at the apex: there can scarcely be any doubt that they belong 
to the same species, and that the elytra vary in development in this insect, as well 
as in WV. nigriventris. 
The macropterous type ( 2 ) in the Stockholm Museum has been examined.

A common species in Mexico and Guatemala. Very like W. crassipes, but smaller, 
narrower, and less robust, the anterior femora less incrassate. Of the fifty-one
