(Plate xx, figs..1-12). 
Larvae, pupae and an adult of this species were found clus- 
tered together on the under side of a large slab of stone, which 
was resting on other stones in such a manner as to leave a clear 
space above the ground beneath it. The pupae hung head down- 
wards from the mid-dorsal fissure of the cast larval skins, which 
remained unshrivelled on the stone in the positions taken up by 
the larvae prior to pupation. 
Adults were obtained in Cochin at altitudes varying from the 
level of the base of the hills to two or three thousand feet above 
the sea, and there is one specimen in our collection from the 
Nilgiris. The distribution of black pigment is very variable, and 
the black spots on the elytra are often absent. A specimen from 
Nedumangad in Travancore, determined by Bourgeois himself as 
L. aurantiacus, Bourgeois,* evidently belongs to the same species ; 
and L. aurantiacus may therefore be regarded as a synonym of 
L. biguttatus. 
LARVA. 
The larva is flattened as a whole, and is of a blackish brown 
colour.
