235 



very scattered. Elytra widest in apical fourth, thence constricted 

 sharply to apex ; moderately convex and depressed behind ; punc- 

 tate, the punctures in longitudinal rows placed rather far apart, the 

 individual punctures at some distance from one another. Legs 

 elongate, black, and shining. Length, 22 mm. 



Larva. Elongate, narrow cylindrical, outer surface very hard 

 and thickened ; dark chestnut brown to blackish in colour, the 

 segments marked by a dark narrow transverse band ; three pairs of 

 legs are present which are functional. Length, 30 mm. to 36 mm. 



Pupa Thick, curved, whitish yellow, the prothorax hooded, the 

 abdominal segments slightly tapering and narrower than thoracic 

 ones. Length, 28 mm. 



This tenebrionid beetle is very plentiful in dead 

 sal-trees in the Assam sal forests.

 Mr. W. F. Perree and myself took 

 it in all stages of larva, pupa, and beetle, in the trees.

Prothorax wider than long, sides but slightly 

 Description. rounded, the median furrow entire and promi-

 spicuous ; punctate, the punctures rather fine and scattered. Elytra 

 slightly wider in apical fourth, thence constricted to apex ; apical 

 fourth depressed ; moderately convex ; strongly and rather deeply 

 striate-punctate, the striae rather close together and rather coarsely
