DESCRIPTION OF THE STAGES. 
1. The Adult. 
Technical Description. —Lameere, 1910, and Gahan, 1906. 
2. The Larva. 
General Description. —Colour (of spirit specimens) brownish-- 
yellow; head chestnut, with the fore margins black; cylindrical, slightly 
tapering, shining, apparently smooth but fine silky hairs are sparsely 
present. 
Technical Description. —Described from 5 larvae 7821-20 in rotten 
wood, Kavalai, 1300-3000 feet, Cochin State, 24-27-IX-14, F. H. 
Gravely, coll. 
HEAD.—Visible portions posteriorly suffused with chestnut, anterior 
margins, carinae, projections and mandibles black. Slightly longer than 
broad, lateral margins at first parallel than very feebly convex; posterior- 
lateral angles broadly rounded. Dorsal margins of epicranium fused to 
the posterior border, hence emargination of the occipital foramen not 
visible from above. Viewed dorsally, the posterior angles and margin 
form a continuous broad curve. 
Occipital foramen with anterior margin transverse, anterior angles 
slightly rounded, lateral margins convergent posteriorly in a very gentle 
curve to the obtuse dorsoventral emargination. Anterior foramen sub- 
pyriform, longer than the intervening tentorium. 
Hpistoma concave, narrow, projecting over clypeus, lateral angles 
acutely prominent. Front raised in a sharp, transverse carina with the 
terminal angles acute and traces of two median dull teeth. Postcondylar 
carina broadly concave, coarsely striate. 
Antennal scrohes very prominent and overhanging dorsally, projecting 
beyond the line of the epistoma. Antennae retracted, but the 3rd joint 
(? 2nd) is evidently long, cylindrical with convex distal surface on which 
is situate a minute tubercular supplementary joiut. Pleurostomal carina 
prominent and sharply margined, external groove deep. 
Subfossal process acutely conical.
