1919.: O-" 



Mid lobe with a group of small brjatles on each side before I just inside the 

 furrows. Axillae narrow, with 2-3 minute bristles aud 1 longer and stouter 

 at the posterior angle. On the 8ci>tellum at the posterior edge are two strong 

 bristles set wide apart. Propodeon, spiracles set near the side at -J, with a few 

 minute bristles behind. There are 3-4 stout stiff bristles on tlie upper edge of 

 the metapleureon and a few (minute) below. Fore wings about 2f as long as 

 broad; length 1-7 mm., breadtli -6 mm. Subraarginal : marginal : radius ; 

 postmarginal in ratio 48: 18: 11: 9. On subnuirginal 8-i) bristles; on 

 marginal + postmarginal at the edge 11-12, and on these veins themselves are 

 9 in all. Radius bare, with 1 bristle at base. Basal third of wing practically 

 bare, but distally and arranged mainly parallel with the long axis of the wing 

 are about a dozen irregular hair-lines ; the cilia short, weak, and wide apart.; 

 Marginal fringe short and sparse. Hind wings 4 times as lang as broad ; 

 length 1-3 mm., breadth -3 mm. The neuration -8 mm. in lengtli. The snb- 

 marginal cell distally extremely narrow, extending linearly nearly to the hooks. 

 At the base of the submarginella where it lies along the costa are 6-7 bristles, 

 2 at the upturn, and 6-8 towards the hooks. Behind the neuration and 

 extending to the tip of the wing is a sparsely set rr)w of weak cilia. 



Fore legs : coxa (3:1) about f the length of the femur (3 : 1), which is of 

 neaily equal breadth throughout. Tibia about | of the femur in length, with 

 about 20 spines, 10 extremely stout and peg-like along the apical edge and 

 about 8 similar behind and 2-3 much weaker near the base. Tar.-^us 

 36 : 18 : 12 : 10 : 33. Mid legs slender. Femur | of the tibia in length, spur 

 of the latter definitely preapical. Sutures of tarsus veiy ol)lique. Tarsus in 

 latio 95:60:40:27:40. Ilind legs: tibia without definite apical comb, 

 2nd spur short, stout, peg-like, only | of the 1st. Two similar small 

 spines among the stout bristles at the upper apical angle. Tarsus in ratio 

 75 : 60 : 40 : 27 : 50. 



Abdomen: tergites 1-2 subequal, the second being slightly shorter; the 

 third is about i longer and equal to the 6th but just shorter than the 5th ; 

 the 4th is half as long again as the 1st, Stvlet short (not as long as the basal 

 breadth of the valve of the ovipositor), with 2 subapical and 2 apical bristles 

 of which thp longest is nearly twice the process itself, Tergites 1-4 have 

 posteriorly 3 median slit-like incisions (the central slit on tergite 1 beinp' 

 carried in to ^ the length of the sclerite), with 1-3 others indistinctly niarktd 

 on each of the overlaps. On 5 and 6 respectively there is 1 short median slit. 

 On tergite 6 there are about 8 strong bristles between, and 3-4 minute around, 

 the spiracles anteriorly with 3-4 behind. 2 stout bnstles (1:1) between the 

 stylets. On the sheath of the ovipositor are 2-3 rows of short bristles in- 

 creasing in length distally. 



Length about 4^ mm., of which the ovipositor occupies '7 mm. ; alar 

 expauj^e 3| mm.
