76 Records of the Indian Museum. [Vo.. XII, 
Thorell (1888, pp. 390-395) records a male from Borneo; but 
from his description of the tarsus of the antenniform legs it is 
clear that the identification is at fault. Kraepelin (1897, pp. 32-3) 
believes this specimen to be the male of T. anthracinus, Pocock. 
In Kraepelin’s key for the identification of species the presence 
of a longitudinal groove in the last sternum is mentioned as one 
of the principal characteristics of both sexes of T. linganus. In 
the female, however, this is not so well developed as in the male, 
and in some specimens it is absent. 
In aseries of 27 specimens of T. /inganus from Johore, eight 
show abnormalities of some kind in the armature of the trochanter. 
Five of these are shown in text-fig. 4. There are no such ab-
