notch behind the middle. Propodeon on each side with a narrow striate triangular 

 area in front of the spiracle in a plane parallel to the mid line of the scutellum. For 

 the greater part the propodeon descends steeply and, seen from behind, is a smooth 

 oblong (5^: 2), with the spiracle at the anterior lateral angle and a large median 

 peduncular emargination (fig. 1, a).

Wings : Fore wing (fig. 2) over three times as long as broad ; length, -8 mm. ; 

 breadth, -25 mm. To give the proper effect the discal cihation of the under as well as 

 the upper surface for the distal two-thirds is shown. On the veins however only the 

 bristles of the upper surface have been drawn except at the base of the radius where 

 a conspicuous small black bristle (rising from below) is figured. The radius itself is 

 bare, except for two subapical bristles, one at each side exactly on the edge. The 

 hind wings are narrow, 3^ times as long as broad ; length (including ciha) '7 mm. ; 

 breadth, -2 mm. The faint embrowning extends from the end of the ner\nire over 

 the apical third. 



Legs : Fore legs, femur (4:1) anteriorly with a sub-dorsal row of 9-11 ver}- short 

 bristles, 3-4 longer median and 3-4 ventral on basal half. Posteriorly, two sub- 

 ventral longer bristles on apical third and 4-5 more medianly. Tibia (7 : 2) short, 

 about three-fourths of the femur, spur long and distinctly preapical. Between it and 

 the insertion of the tarsus the comb contains five spines. First tarsal joint broad, 

 with comb of 9 closely set spines. The first and the last joint are equal, and 2-4 are 

 equal and half as long as 1. Mid legs elongate, slender, with femur normal, antero- 

 posteriorly compressed. Coxae (3 : 2) with vertical row of 'j-G bristles, fenmr (13:2)
