THE BUTTERFLIES OF CEYLON 119 
This is a variable insect. The hyaline spots on the fore 
wing vary much in size and shape, the two in interspace 1, 
and the one at the upper margin of the cell being often nearly 
obsolete. In all my males there are three pre-apical spots, 
but the females sometimes have four or five. Some speci- 
mens have a faint marginal row of pale spots, with a sub- 
marginal row of more conspicucus ones in interspaces 4, 5, 
6 and 7, thus disagreeing with Elwes and Edwards’ classi- 
fication of the species. The markings on the under side are 
very variable. 
It is fairly common at Haldummulla during the south- 
west monsoon (dry season), but becomes much more abundant 
at a lower elevation, and I have taken it all over the low- 
country of Uva and at Trincomalie and Vavuniya. The 
males are most frequently found settled on the wet sand in 
river-beds or on wet roads; the females visit flowers, and 
seldom fly far if disturbed. 
The clasps are figured on Plate 4, figs. 9 and ro. 
197. CAPRONA SIAMICA? Not mentioned in any list that 
I know of Ceylon Butterflies, but it is very near to C. saraya. 
See Plate 2, fig. 5. Capt. Riley has compared a specimen 
from Ceylon with the type of sszamica and thinks our form is 
wrongly named, and that it is true saraya. 
Elwes and Edwards, in their analytical table of the genus 
Caprona, divide the species by two important characters : Ist, 
the possession of ‘“‘a terminal row of pale spots on the fore 
wing above”’; and 2nd, the presence of ‘‘a hyaline spot in 
the cell of the fore wing above, near the middle.” Neither 
of these help to place this species. The row of pale spots is 
sometimes very prominent, but in other specimens it is equally 
obscure. The spot in the middle of the cell is usually present, 
but I have specimens without it. The other hyaline spots 
seem fairly constant, but the large one at the end of the cell 
is sometimes divided into two very small ones. The pre- 
apical spots usually number 5, but they are sometimes reduced 
to 3. Asarule, the under side of the hind wing is pure white, 
but it is occasionally tinged with ochreous. The ring of small
