the upper. Moore’s figures of the under side, and of what he 
calls the female, are fair. That of the male is, I believe, that 
of a variety of silhetana. The female resembles the male in 
the shape and markings of the fore wing, but is paler in colour. 
The border of the hind wing is a very fine black line, widening 
out into slightly diffuse triangular spots at the end of each 
vein. This border is sufficient to distinguish the female from 
any other Ceylon Tervias. The types are in the British 
Museum. The female is what I call rotundalis: the male 
is the variety of st/hetana, which I have described in the 
previous article. . 
The reddish apical patch below is wanting, its place being 
sometimes taken by an indistinct patch of black scales. 
Judging from my specimens, this species varies less than any 
Tervias in Ceylon. 
Evans writes: “‘ sarz is recorded from Southern India and 
Ceylon; the only specimens in the British Museum marked 
as such are two from Ceylon, which may be andersoni, but are 
certainly not savz.’’ These are what I call votundalis, 
and are now placed under that name. 
Pending a decision as to whether this is andersoni, or a 
race thereof, I retain Moore’s name. 
I have taken it at Wellawaya and Buttala in the low- 
country of Uva, and have specimens from Kandy, but it is 
apparently only plentiful at Ratnapura and in other very 
wet forests. 
157. IXIAS PYRENE CINGALENSIS, E. Ixias cingalensis, 
M. Ixtas pyrene var. cingalensis, B. Moore also gives 
pirenassa, under which name he describes the dry season form. 
It is said to be peculiar to Ceylon, but is very near pyrene, 
from which it differs in having the ground colour of the fore 
wing extended into the base of interspace 3. This seems to 
be constant, though very variable in amount. I have received 
specimens labelled Madras and Bangalore which seem to 
be identical with cingalensis. 
The males vary chiefly in the width of the black border of 
the hind wing and the amount of markings on the under side. 
The females vary in the same way, but the band on the fore
