56 SPOLIA ZEYLANICA. 
111. Castatius ErHiIon.—Also in India, Burma, Malaya, 
&e. 
Much more a jungle fly than the last, and is fond of settling 
on a twig or leaf projecting over a jungle path. 
Is found nearly all the year round at Haldummulla, but is 
usually commonest in April and May. 
It is common in the south of the Island, especially in the 
wetter districts, and I have taken it up to 5,000 feet elevation 
at Haputale. I have so far not taken it north of Dambulla. 
112. CasTaLius DECIDEA.—Also in India and Burma. 
Moore also gives C. hamatus, but Bingham says this is only 
the wet season form. They certainly grade into one another. 
In Ceylon the variation seems to depend very little on 
rainfall. Some of mine with an exceptionally narrow band 
(viz., hamatus} were taken here in the dry season, and some 
with the broadest band were taken from March to May, 
when there is a tair rainfall. Others are from Galle, which is 
in the wet zone. 
It is a jungle fly, with habits like the last, except that it 
apparently flights at times. 
It seldom settles on wet patches on the roads, like rosimon. 
I have ‘only taken it in the southern half of the Island, and 
never at any great elevation. It is very plentiful at times at 
Galle, and I have also taken it at Kegalla and Peradeniya. 
113. Potyommarus Ba@ricus.—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.” 
One of the commonest butterflies. Is found everywhere, 
and is equally common in Galle, Jaffna, and Nuwara Eliya. 
It varies very greatly in size, dwarf forms being very 
common. The female varies in the amount and shade of 
blue on the upper side. 
114. Ampiypopia Antta, De N. & E.; Amblypodia darana 
and naradoides, M.-Also found in India, Burma, Siam; and 
Borneo. ; 
Moore says darana is larger than naradoides, the male being 
a darker blue and the marginal band narrower ; the anal lobe 
is red only in the middle, its margin and the tail being black. 
The @ is uniformly brown above. I have not yet acquired
