Wings. —Quite clear. Third longitudinal vein ends at middle 
of wing; fork rather small, but distinct; rst longitudinal ends 
just beyond middle of costal cell, straight. Costa with a row of 
short bristles, and a second row of much longer ones set further 
apart. Auxiliary vein very indistinct. Of the discal veins, the 
Ist is moderately curved, 2nd gently bisinuate, 3rd and 4th nearly 
straight, all attaining border of wing. MHalteres dark brown. 
Described from a single specimen in the Indian Musem from 
Thamaspur, Nepal, 18—2o-11-08. 
N.B.—This appears to be near the A. sodalis of Brues, 
described from New South Wales, and which he considers very 
close to, if not identical with, his crasstmana, from New Guinea. 
My species differs in several characters from both of them and is 
conspicuous chiefly for the great difference in length of the two 
rows of costal bristles, from which it takes its name. 
‘Hypocera marginata, mihi, sp. nov. 
9. South India. Long. 24 mm. 
Head.—Frons shining black, practically bare. The Ist row 
of bristles vertical; 2nd row of four equidistant ones curved 
upwards; 3rd row of only one each side; 4th row similar, the 
bristles placed one on each corner of the frons, which somewhat 
narrows in front ‘Two smaller proclinate bristles in front. Fron- 
tal groove only visible for a short distance in front; ocellar 
tubercle absent. Antennae bright reddish orange, arista black, 
orange at base. Palpi pale yellow, with four or five strong bris- 
tles at tip. Eyes with the usual row of bristles, which continue 
round the lower corners. Back of head black. 
Thorax.—Dorsum wholly black, except the posterior margin 
from one wing base to the other which is irregularly yellow: 
dorsum entirely covered with close short stiff black hairs, with 
several stronger bristles along the posterior margin, and a power- 
ful long spiny bristle on each posterior corner. Sides dull black, 
with a faint bluish tinge. Scutellum blackish, with yellow margin 
and four spines, the outer upper pair less strong. 
Abdomen dull black, bare, emarginations of segments barely 
pale; posterior border of 5th segment broadly yellow. Belly black. 
Ovipositor small, dark sub-conical, apparently of two segments. 
Legs.—Uniformly yellowish, hind tarsi barely darker; hind 
femora towards the tips black. Fore tibiae with a row of very 
short bristles on outer side; posterior tibiae with a double row of 
longer ones, and some very small ones about the tips; the hind 
pair having some rows of microscopically small black hairs. 
Wings.—Very pale brownish yellow, 3rd longitudinal vein 
barely reaching middle of wing. It is of uniform width to. its 
tip where it is very slightly thickened, ending free, but with a 
faint fork issuing just before the tip, uniting it to the costa. 
The Ist longitudinal vein ends at two-thirds the length of the 
costal cell. Costal spines short. Of the discal veins, the tst is
