pronotal process. Anterior femora narrow, carinas subentire ; 
posterior tarsal pulvilli below straight, the third pulvillus little 
longer than the second. 
Length of body <$?, 6-8 mm.; pronot. 7*5-9*5 mm.; posterior 
fern. 4-6 mm. 
Locality, Ceylon (Bolivar). It is also reported from Java and 
the Philippines. 
Parcitettix personatus, Bolivar (1887, p. 278). 
The following series of fifteen specimens referable to this 
species are given in two separate series of measurements selected 
from different localities. This is done with a view of giving 
more concisely the range of variations occurring in the species. 
There are some marked structural variations in individuals diffi¬ 
cult of measurement. For instance, two females taken at random, 
one from Kesbewa and the other from Peradeniya, show in the 
first-named specimen, the median carina of the pronotum begin¬ 
ning from just behind the front border backwards to the apical 
process, a succession of five distinct undulations, diminishing in 
size backward. While in the second specimen from Peradeniya, 
the median carina of pronotum is elevated but straight above 
between the shoulders and very indistinctly undulate backward. 
In the latter specimen the head is not so distinctly exserted, yet 
both forms are doubtless varieties of the same species, for there are 
some individuals presenting intermediate stages connecting the 
two types of individual peculiarities. The antenna? of the males 
are unusually long in this species, having the distal five articles 
appreciably compresso-ampliate. The hind tibiae of both sexes 
are usually black or fuscous with a light annulation near the 
knees.

Colombo in April by Mr. Green.
