Head: rostrum <lark l)r<iwii; iinlennir uniform dark brown. Front, verli'X and 

 occiput light grey, sutVuscd with brown. 



Thonix: pra-scutum rich light brown without apparent paler stripes; sides of the

 a sparse greyish bloom. Pleurie light brown, llaltercs light brown, stem paler. 

 Legs uniform light brown. 



Wings subhy aline, veins light yellowish-brown. Venation; (See fig. i.) ; Sc ending 

 opposite origin of Us, basal deflection of AI1+3 about equal to that segment of Mi+i 

 between cross-veins r-m and in; basal deHcction of Cui usually at, or very close to, 

 the fork of M; basal approximation of Cu and 1st A moderate, about one-third of 

 the length of Cu beyond the areulus. 



Abdomen, tergiim, sclerites light brownish-yellow, the apice and basis of eac:h 

 sclerite broadly brown, eadi baud as broad as the median pale band; sternum light 

 yellow, the apical fifth of each sclerite brown. Ovipositor of the 9 , upper valve, 

 very long and slender, lower valve also slender, but stouter than the upper valve.

This species exliibits some differences in coloring and other vari- 

 ations from the type-description but I am (juite certain that but 

 one species is included. Most of the si>ecimens show clearly the 

 dark basis and apice of the abdominal tergites. Some variation 

 exists in the position of the basal deflection of Cui, in relation to 

 the fork of M. In most specimens it is close to, or at, the fork; 

 in some rather far proximad of the fork; in paratype No. 9 it is 

 distad, underneath cell 1st Mj. A few examples show an open 

 1st Mo, occasionally one wing exliibiting this character while the 

 opposite wnng is quite norm.al.
