[See Text figure 1, p. 4] 
Technical description. —Described from 5 larvae, ex soil near roots 
of 8Korea robusta } Buxa Division, Bengal 21-22-1-1915, C. F. C. B. coll.; 
ditto Gorakhpur Division, U. P., 17-1-1918, C. F. C. B. coll. 
LARVA, very smooth and shining; pubescence sparse and silky. 
HEAD, visible portions black. 
Epistoma concave, projecting over clypeus, lateral angles obtusely 
rounded, two blunt teeth medianly; front raised in a low transverse 
carina, slightly arched forwards, notched in the middle behind which the 
median line is impressed, lateral angles tuberculate; Postcondylar im¬ 
pression well marked with the limiting carina broadly concave. 
Antennal scrobes , elevate, thickened and truncate on inner sides, 
depressed and angularly emarginate postero-laterally. Pleurostoma with 
a well marked carina succeeded by a triangular furrow. 
Subfossat process an acutely conical tooth. 
Mandibles rugosely elevate at base; a conspicuous transverse im¬ 
pression in the median area, and a prominent rounded tubercle in front 
of the dorsal condyle. 
Clypeus very narrow almost concealed at the epistome. 
Labrum subcordate, gradually rounded from base to obtuse apex; 
posterior area dark brown, anterior area yellow and more densely pubes¬ 
cent. 
PROTHORAX. Pronotal plate transverse, lateral borders rounded 
and slightly convergent anteriorly; median line faintly impressed; disk 
irregularly striate and punctate; anterior margin marked by a zone of 
stronger chitinisation. Prosternum with eusternal and presternal areas 
separated by a complete curved suture. 
ABDOMEN. Ambulatory ampullae , with dorsal series of impres¬ 
sions subfusiform, ventral series all slightly curved forwards. 
Pleural discs prominent, radially striate, circular on segments 1—3, 
elliptical on segments 4—5. 
Length 80 mm. Breadth 15 mm. 
Notes on the Life History. 
Larvae agreeing generally with the foregoing description were found 
under the following conditions :— 
1. At Rajabhatkhawa, Buxa Division, Bengal, in the soil close to 
the roots of dead sal trees [S. T. 58, 59] attacked by the root fungus,
