“Larvae.” — Large, broad, and thick. Antennae with 11 to 17 
segments; when 17, segments 2 and 3 incompletely separated; 
other segments short, thickly clavate, with thick distal and 
narrow proximal ends, or suborbicular. 
SYSTEMATIC POSITION 
While it is difficult to determine the generic position of the 
species of Kalotermes in the absence of the adult, I feel 
that there can be little doubt in the case of the present species. 
The short legs with swollen femora, the large and heavily chiti- 
nized third antennal segment, the presence of distinct wing 
pads and, finally, the distinct difference in shape of body, degree 
of chitinization, size and shape of pronotum, etc., which dif- 
ferentiate it from the common species of Neotermes, make it 
practically certain that we have in this species a representative 
of the genus Kalotermes, which is here reported from the Islands 
for the first time. Were it not for these striking differential 
characters one might well hesitate to report a Kalotermes species 
in the absence of the winged adult, in view of the absence of any 
species of this genus in the known termite fauna of Formosa 
and Japan to the north and the East Indies, Ceylon, etc., to the 
south, the only oriental species being K. indicus (Holmgren), 
known only from the adult. An exiamination of the venation 
of the wing pads of “workers” collected recently confirms
