 at distal half of wing of remarkable length and curvature ;

Pale ochreous-yellow. Antennae and palpi somewhat tinged 

 with brownish ; flagellar joints elliptical. Thorax, with the meso-

 distinct traces of a double median stripe ; a brownish triangular 

 spot on each side above the origin of the wings ; a small spot 

 about equal in size to the last on the pleurae ; metanotum with a 

 narrow lateral border of brown, which is continued as a brown 

 line down the sides of the abdominal segments* ; second segment 

 with a median brownish marking ; 9 ovipositor short, little curved, 

 ochraceous-brown. Eore cox£e bordered with brown anteriorly ; 

 femora with a more or less distinct brown ring a little before the

 whilst in old specimens the sides of the segments of the abdomen sometimes 

 overlap, and thus entirely conceal the line.
