THE BUTTERFLIES OF CEYLON 141 
Kottawa, Deniyaya, and Kandy. I understand it is not 
tare at Balangoda, and has been taken in Nuwara Eliya. 
The prehensores are figured on Plate 6, figs. 65 and 66.

230. HASORA (PARATA) BUTLERI, E. Parata alexis, M. 
H., butleri is found also in Southern India. Races of chromus 
are found in India, Burma, Dutch Indies, etc. 
A revision of the genus will probably result in both forms 
being divided into several local races. The present nomen- 
clature does not seem satisfactory. 
Elwes and Edwards treat them as varieties of H. chromus. 
The external differences are very marked, they fly together 
and do not grade, and their prehensores are widely different. 
The clasp of chromus is the same as Elwes and Edwards’ 
figure of that of inermis. I have examined a large number 
from Ceylon, India and the Andamans, and find it very 
constant. The tegumen shows signs of four rudimentary 
horns, see Plate 6, figs. 63 and 64. The clasp of bwilert is 
that figured by Elwes and Edwards as chromus, and the 
tegumen has four long horns See Plate 6, figs. 61 and 62. 
It is practically identical in specimens from Ceylon and 
Kanara. I have had a few allied, but distinct forms from 
North India, but have only seen true butleri from South 
India and Ceylon. My material from anywhere else than 
Kanara and Ceylon has however been far too limited. 
The upper sides of the males of our Ceylon forms are similar, 
but the under sides are very distinct, the most prominent 
difference being that budleri has a broad, sharply defined, 
white band on the lower wing, and chromus has a narrow 
diffuse one. The female of butlert has, as a rule, two small 
white spots on the upper side of the fore wing in 2 and 3, of 
which the lower is much the smaller, but both these spots 
are often absent. In this case the ¢ can only be distinguished 
from the ? by the absence of the sex mark. This form of 
female is sometimes mistaken for the male of H. chabrona, 
which I do not believe to be found in Ceylon. The female of 
chromus has two spots in all my specimens, of which the lower
