globose, with a whorl of 10-12 bristles, the 3rcl and 4th also sometimes with 
1 sensorium eaeh. The elub, mueh swollen, ^ as wide again as last funieular 
joint, 3 jointed, the last with a short spur, possesses sensoria (a) 3, (6) 4, (c) 2. 
Mouth parts essentially as in the ?. Mandibles narrower, the outer tooth 
stronger and a little more incurved. 
Thorax. Prothorax largely developed, quadrate, pronotum longer than the mid 
lobe of the mesonotum. Posterior edge straighter than in the Overlap 
in the d oblong while in the $ more cut away from the anterior to the postero¬ 
lateral angle. Prosternum practically square, 2 minute median bristles. 
Episternite with 10-12 bristles. Parapsidal furrows showing a distinct 
chitinised folding only shortly anteriorly, but continued back to the suture 
as a broad pale blaze. Chaetotaxy of mesonotum as in the ?, with fewer 
bristles on mid lobe, scutellum without impressed lines and showing only two 
pairs of setigerous pustules, (a) at J, and (b) on posterior margin. Pattern of 
thorax all over finer and fainter. Sternopleural surfaces—including even the 
prepectus—smooth. Metathorax and propodeon as in $, smooth except the 
lower pleurae where the bristles are stronger and all equal. Internal median 
propodeal thickening more pronounced in (?. 
Wings. Narrowed and reduced on apical \. Fore wings (3: 1), length 0-54 mm., 
breadth 018 mm. Long, oval, contracted a little near base, anterior and 
posterior margins subparallel, submarginal; marginal : radius 5:5: 1. The 
postmarginal rudimentary. Submarginal cell large, with 6-8 bristles, sub¬ 
marginal vein 4 bristles, marginal 3 bristles at origin and 6 stouter overlapping 
the costa with the same number (finer) from below. Radius—3 on vein and 
1-2 on head which has 3 cells. Basal triangle up to origin of marginal vein 
bare. Thence, parallel and near to hind margin, extending to end of frenulum, 
is a row of bristles with a broad bare line anteriorly. Discal cUiation dense 
and stout, fringe fine, very short. Hind wings (4 : 1), length 0-37 mm., breadth 
0-9 mm. Besides the 2 basal bristles the vein bears 1 stronger and 1 weaker 
before the 2 clear cells. Retinaculum weak. Fringe longer and stouter than 
in fore wings. 
Legs. Fore legs, coxae (9:5) large, swollen, f of the femur, pattern weak and 
obscure except externally on posterior surface where the cells are large. 8-9 
short weak bristles in 3 transverse rows and 2-3 longer apically—all on outer 
anterior surface. Inner surface bare, faintly reticulate. Femur (3:1) swollen 
beyond lower edge straight, anteriorly set evenly with bristles, no ventral 
row. Fewer bristles posteriorly and chiefly on apical |. Of these 5-6, median 
.subapical, are stronger. Tibia (5:1) as long as femur, swollen at about 
with similar bristles to femur, but barer posteriorly—only 6-8 (short) in a 
subdorsal row which curves inwards at apex where the irregular comb consists 
of 6-8 spines. Tarsal joints remarkably bare, 3 and 4 fused but not quite com¬ 
pletely, there being an internal S-shaped incrassation at the union of the joints. 
The 1st joint bears anteriorly 3 stout ventral bristles, 1 in the middle of the 
sloped apical edge, and 1 (finer) at the dorsal apical angle. 3 fine postero- 
ventral spines; 2nd joint like the 1st but with 1 spine anteriorly and another 
posteriorly. The fused joints repeat the arrangement of the second. Mid 
legs, coxae large, swollen, with surface externally shagreened or scaly reticulate—
