52 SPOLIA ZEYLANIOA. 
in every compound, wayside hedge, or grassy field, up to an eleva- 
tion of about 4,000 feet. And yet, to the best of my belief, no 
published description of its early stages or transformations has -yet 
appeared. Y. ceylonica is now considered to be a local race of the 
Indian form huebneri, Kirby, of which the larva and pupa are 
‘known ; but our Island race of the insect has not apparently been 
bred up to the present time. 
Having taken a pair of the butterflies in cottu on November 23 
last, [ placed them under a glass shade with some living grass 
plants in hopes of obtaining ova. The male insect died on the 25th. 
No eggs had then been deposited, though the female was still active. 
On the following morning I found two small globular eggs, laid side 
by side, near the base of a blade of grass; two more eggs were 
attached to the extreme tip of another blade, and three others on 
the under-surface of a broad leaf of ribbon-grass. When magnified 
it is seen that the egg is not truly globular, but has a slightly longer 
vertical diameter. It is wider towards the base, and very slightly 
flattened above and below. The surface is closely pitted with 
irregular polygonal depressions. The longer diameter is approxi- 
mately 0°75 mm. : 
The eggs hatched on December 3. The young larve are of a 
very pale pinkish white tint, with a reddish median-longitudinal 
line and a similar dorso-lateral line on each side. The sides are 
more or less completely suffused with rosy red. Every segment, 
including the head, has a transverse series of colourless tubercles, 
each supporting a longish obtuse white hair. Head large, fully 
twice the width of the following segments. 
December 10.—The young larve are undergoing their first 
moult. At the end of the first stage the pink colour of the newly 
hatched larva has entirely disappeared, being replaced by whitish 
green ; the body has thickened until it has exceeded the width of 
the head ; the tubercles have become less prominent and conspi- 
cuous ; the dorsal, subdorsal, and lateral lines are dull green. 
After the moult the most marked difference is the appearance of a 
pair of pointed, conical, divergent processes on the terminal segment. 
December 18.—The larve have moulted for the second time. 
There is no marked change in their appearance. 
December 24.—The larve are preparing to moult for the third 
time. They are now of a uniform whitish green tint above, with a 
conspicuously paler lateral line, below which the underparts are of 
a clear grass-green colour. Upper parts with fine longitudinal 
darker stripes ; the derm roughened with minute spicules, some of 
which carry a fine blackish hair. 
Absence from headquarters prevented observation of subsequent 
moults; but on January 7 the larve appeared to be fully 
grown, and one of them had suspended itself preparatory to 
pupation. ,
