52 SPOLIA ZEYLANICA. 
Exceedingly plentiful all the year round at Haldummulla, 
and I have taken it from Galle to Mannar, but it is commonest 
in the south. It is common in Nuwara Eliya. 
104. CATACHRYSOPS STRABO.—Also found in India, Malaya, 
Australia, &c. 
Very common in Ceylon, everywhere at low elevations, but 
becomes rare above 3,000 feet. 
In his key to the genus Catachrysops (Bombay Nat. Hist. 
Journal, Vol. XXIII., p. 491), Bell gives, as the distinction 
between the species, the fact that strabo has “ a dot on costa 
between discocellulars and post-discal band of spots.” This 
dot is sometimes absent in Ceylon specimens of strabo, and 
I have a specimen of cnejus which shows it. In strabo and 
lithargyria the eyes are hairy, in pandava and cnejus they are 
smooth. 
Not given to settling on wet roads, but both sexes fly low 
in open ground and settle on flowers, &c. It is especially 
plentiful in abandoned low-country paddy fields and chenas. 
I have specimens from all over the low-country, from Galle 
to Jaffna, and the males show no marked variation dependent 
on climate, &c.; the females, however, vary in the amount of 
blue on the upper surface. 
105. CATACHRYSOPS LITHARGYRIA.—This is said to be 
found wherever strabo exists, but I believe that the only 
females known were caught in Ceylon. Bingham thinks it is 
only a variety of strabo, and says: “Nor has any corres- 
ponding difference been found among the females, while in 
the blue males the markings are precisely the same as those 
of typical males.” 
These remarks cannot poste refer to Ceylon specimens. 
The 3 differs not only in colour, but in the shape of the wings, 
and on the under side the markings are far broader, better 
defined, and an entirely different colour, the general appear- 
ance being very dissimilar. The female is much larger than 
any specimens of  strabo I have seen, and the blue on the 
upper side is paler ; the markings on the under side agree with 
those of the male, though lighter in colour, but are even 
broader. Moreover, it is apparently constant, and I have 
seen no signs of its grading into strabo.
