De Saussure gives the following measurements: ?, Length of 
body 26 mm.; pronotum 25 mm. ; width of pronotum. at shoulders 
5 mm. ; post. fern. 9 mm. <5, Length of body 23*5 mm. ; pronotum 
22*3 mm.; width of pronot. at shoulders 4 mm,; post, femora 
7*7 mm. 
Locality, Peradeniya; October and November (De Saussure). 
Of the above tabulated specimens one female, Dambulla, October, 
“from margin of tank two females, Maskeliya, November and 
February ; five females and four males, Pundalu-oya, March, were 
taken “from rocks in mountain streams; when disturbed, 
either takes wing, or dives under water and remains submerged 
for some time ; larva in similar situations.” Two more males and 
several nymphs were taken in June from the same locality. 
The young, even in the early stages, are easily distinguished 
from Scelimena logani , the next allied species, by the narrower 
vertex, the smoother body, and absence of very distinct teeth on 
the lower margins of femora. The adults furthermore differ from
