Ichneumonidae. 469 
broad, with 2 teeth of equal size. Legs stout, as in the 
rest of the group ; the last joint of fore tarsi large, dilated. 
This genus should be readily known by the very 
large elongated metathoracic spiracles. 
Megatrema albopilosa sp. nov. d!. 
Black, the basal 14 joints of the antennae and the 
anterior legs, except the coxae, red, smooth, shining, 
densely covered with white pubescence; the spurs white; the 
wings hyaline to the transverse basal and median nervures, 
fuscous, tinged with violaceous beyond, the nervures and

Sikkim. 
Face and clypeus strongly, closely punctured ; the 
hair on them longer and denser than elsewhere ; the 
front and vertex are more closely and finely punctured. 
Mesonotum and scutellum sparsely, weakly, but still 
distinctly punctured ; scutellar depression deep ; on it are 
2 stout keels on eitherside of the middle. Pleurae covered 
with long white hair ; the hairs coming from punctures. 
Base of metanotum smooth; the apical slope strongly, 
irregularly punctured ; the apex of the central part raised, 
finely striated, roundly incised above. Below the base of 
the scutellum are 5 stout, clearly separated oblique keels. 
Abdomen twice the length of the thorax; its apical segment 
bluntly pointed, densely covered with black hair. The 4 
anterior femora are much more swollen than the posterior. 
Post-scutellum raised in the middle, depressed widely 
laterally at the base. The hair on the tibiae and tarsi are 
densely covered with white pubescence, which gives 
them a white appearance ; the femora are more sparsely 
covered with longer white hair. (To be continued.)
