Two females and five males taken at Kandy, Mahaweli-ganga 
in January, one in June, with a number of nymphs. 
“ Aquatic ; on rocks.” A single male “ from rocky stream ” 
was taken at Haragama in January by Mr. E. Ernest Green. 
Judging from the foregoing this species has aquatic habits 
similar to those of Scelimena gavialis , De Sauss., and this supposi- 
tion is borne out by the structure of the posterior legs, which, are 
widely laminate expanded at the lateral margins of the tibiae and 
first joint of the posterior tarsi, being in this particular even little 
more specialized than in gavialis.
