water (see Carpenter, Journ. As. Soc. Bengal, 1913, p. 215). 
Neanura pudibunda is of a bright red colour and possesses eyes. 
The two species occur together. 
Among the Orthoptera of the caves the most interesting 
are the wingless grasshoppers of the subfamily Stenopelmati- 
nae, of which three species have been recorded from them, one 
from the Farm Caves (Diestrammena unicolor, Brunner), one 
from those of Jalor (D. annandalei, Kirby), and one from the 
Batu Caves (Diestrammena, sp.). A fourth was discovered by 
Gravely in the Farm Caves, but its specific identification is a 
little doubtful. It belongs to the genus Rhaphidophora and is 
identical with one (probably R. brunneri, Kirby) that occurs in 
the jungles of the same district. Unlike the species of Diestram- 
mena, which live as a rule on the cave-walls and on rocks 
D. unicolor is reported to occur in northern China (Vladi- 
vostok and Pekin) as well in the Farm Caves, but in Tenas- 
serim has only been taken in them and in those at Dhammathat 
in the same district. In the caves it is extremely abundant. 
It exhibits considerable individual variation in colour, and the 
nh nhene of our specimens are both antennae complete, but in 
caves has not been identified, and may be the same as one 0
