Opening of pygofer about as long as broad, dorsal emargination en- 

 closing about half the anal segment, anal angles of pygofer not pro- 

 duced; anal segment with two short, stout spines; genital styles reaching 

 nearly to the anal segment, flat, narrowest at middle, apex truncate, 

 inner angle sharp, outer angle rounded ; aedeagus tubular, straight, apex 

 produced into an acute point, orifice on ventral aspect near apex, four 

 spines on each side about one-third from apex, the more ventral ones tlie 

 larger. 



Pale orange yellow inclining to green ; fuscous between carinae of 

 Tiead and thorax, apex of rostrum and claws of feet brown, slightly 

 fuscous on dorsal aspect of abdomen. Tegmina pale orange yellow in- 

 clining to green in some specimens, a brown mark at apex of clavus 

 and a small lighter mark at apex of costal cell, the dark mark at apex 

 of clavus continuing as a faint infuscation across the tegmen to the 

 base of costa, veins same color as membrane, no granules but a few 

 fine, black hairs on veins. 



Female. Brachypterous ; length 2.7 mm.; tegmen 1.8 mm. The dark

Pygofer round, opening wider than long, dorsal emargination deep, 

 nearly surrounding the anal segment, anal angles produced into a bluntly 

 curved point ; anal segment without spines ; genital styles reaching nearly 

 to anal segment ; widest at base and apical third, apex pointed : the 

 armature on phragma forming a long, narrow process standing U]) from 

 the phragma, the dorsal edge being slightly emarginate where the aedea-

 greened ; aedeagus long, semitubular, curved, orifice at apex on dorsal 

 aspect, a row of teeth on each side, that on the left being more dorsad
