60 THE BUTTERFLIES OF CEYLON 
plentiful in abandoned low-country paddy-fields and chenas,. 
I have specimens from all over the low-country from Galle 
to Jaffna, but it becomes rare above 3,000 feet. 
104. CATACHRYSOPS LITHARGYRIA. 
De Nicéville and Bingham consider this to be only a variety 
of strabo. The former writes: “‘ The two always appear to 
occur together, and the female of the latter species 
(lithargyria) is even now undescribed.’’ Bingham writes: 
“Nor has any corresponding difference been found among 
the females, while in the blue males the markings are 
precisely the same as those of typical males.”’ 
Among the original sketches for Moore’s “Lepidoptera of 
Ceylon,” now in the Colombo Museum, there is an excellent 
plate of the female lithargyria, but tor some reason it was not 
published. 1 therefore give one in Plate 1. Fig. 5. The 
male differs, not only in colour and size, but in the shape of 
the wings, and on the under side the markings are far broader,’ 
better defined, and of an entirely different colour, the general 
appearance being very dissimilar. The female is much 
larger than any specimens of stvabo I have seen, and the blue 
on the upper side is paler. The markings on the under side 
agree with those of the male, but are lighter in colour and 
broader. It is apparently constant, and shows no signs of 
grading into stvabo. The male may easily be mistaken for 
L. celeno on the wing as the colour is the same, though paler. 
The genitalia closely resemble those of stvabo. 
It is very rare. I have taken one male and three females 
in the tea on this estate, and one or two males at Wellawaya 
settled on carrion, or wet patches on the roads. Mr. F. A. 
Fairlie tells me that in March, 1898, he caught several perfect 
specimens of ¢ and @? at Bakers Farm, Nuwara Eliya(6,000 
feet), which is certainly not a locality for strabo. 
105. EUuCHRYSOPS CNEJUS. Catachrysops cnejus M .— 
Also found in India, Malaya, China and Australia. 
The males can be readily distinguished from other Ceylon 
species of Catachrysops by having on the upper side of the 
hind wing two nearly equal sized black spots, one each in
