THE BUTTERFLIES OF CEYLON 59 
101. LAMPIDES CELENO, B. and E. Lampides aelianus, M., 
De N. Also found in India, Malaya, China, etc. 
The upper side varies very little. The under side varies 
in the ground colour and markings, but I cannot see that the 
variations depend on climate in Ceylon. 
The male is often seen settled on wet roads, but both sexes 
are more frequently found on the bushes and grass by the 
roadside. 
The male has the same habit as H. bolina 3 of taking up a 
position for days, and attacking every butterfly of about its 
own size that passes 
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. | 
102. LAMPIDES Be&tTICcUS. Polyommatus beticus, M., B., 
De N., E. 
Also found in Europe, Asia, Africa and Australia. It is 
said to have been taken in England, and is included in English 
lists as the “ long tailed blue.”’ 
It varies greatly in size, dwarf forms being very common. 
The female varies in the amount and shade of blue on the 
upper side. 
It is common everywhere, at all elevations. 
“In Mauritius it does great damage to garden peas.”

103. CATACHRYSOPS STRABO. 
Also found in India, Malaya, Australia, etc. 
In his key to the genus Catachrysops, De Nicéville distin- 
guishes C. stvabo and C. lithargyria from the rest by “ both 
sexes with a distinct small dusky costal spot between the 
disco-cellular and discal bands on the under side of the fore 
wing ; eyes hairy.’ This dot is sometimes absent in Ceylon 
specimens of stvabo, and I have a specimen of cwejus which 
shows it. The hairy eyes seem to be the most reliable test. 
The males vary little, and the females only in the amount of 
blue on the upper side. . 
It is not given to settling on wet roads. It is especially
