Griotettix tricarinatus , Bolivar (1902, p. 583 ; Kodiakanal, 
South India). 
I am indebted to Professor Bolivar for a pair of this graceful 
species. The labels bear the single designation, Ceylon. My 
collection, moreover, contains two males from Pundalu-oy a, Ceylon, 
which were kindly contributed by Malcolm Burr. A large series 
from E. Ernest Green, comprising sixty-nine specimens from 
Kandy, were collected in January; forty of them were in preser¬ 
vative solution. They were collected “ on the banks of river.” A 
singlefemale, also taken in January, was “ caught on railway bank” 
at Kadugannawa; while a pair is represented from Peradeniya, 
taken “ from grass land ” in May. 
There were nearly twice as many males as females represented. 
This species is exceedingly variable in colour, being f requently 
light grayish infuscated or maculate on the pronotum, the 
posterior femora often being mottled with fuscous. 
The following measurements of six specimens of each sex show 
in a certain degree the range of the variations :—
