The Lucanid larvae described below were found in wood to- 
gether with adults of the species to which I have referred them. 
In no case were any pupae found.

Locality.—Andamans: Port Blair (in rotten wood). 
Two larvae about 25 and 30 mm. long respectively, accom- 
panied by two mesodont males of slightly dissimilar development. 
The larvae are of the usual curved clavate form. 
The head is polished and obscurely rugose. It bears a few 
long slender hairs in a line behind the clypeo-frontal suture and the 
antennae, as in Dorcus parallelopipedus. The sutures bounding the 
frons latero-posteriorly, though distinct, are very weak. The cly- 
peus is somewhat or much broader than long in front ; behind it is 
quite twice as broad as long. The labrum is about twice as broad 
as long behind, and somewhat broader in front; its anterior mar- 
gin and angles are rounded; it is lightly elevated in the middle 
line in front, between a pair of marginal or submarginal depressions. 
The antennae resemble those of Dorcus parallelopipedus, but 
have the last of the two long joints scarcely longer than the first. 
I would regard these antennae, and those of other Lucanids, as 
apparently 5-jointed and really 4-jointed; not apparently 4-jointed 
and really 3-jointed asdoes Schigdte. Both mandibles have three 
teeth at the apex, of which the ventral is situated infront of the 
middle one, and the middle one in front of the dorsal. In the right
