152 Mr. G. F. Mathew’s life-histories of 
is of the usual Lycena form, 18 to 15 mm. long, rather 
slender in proportion to its length; whole surface a 
beautiful pea- or apple-green, in some individuals the 
green upon the dorsal area being tinged with golden- 
yellow; viewed through a lens the whole body is irro- 
rated with minute whitish dots, and a few short light- 
coloured bristles spring from the spiracular region, and 
above the head and anal flap; segmental divisions 
clearly defined; four short dark-coloured dorsal bristles 
upon each segment, springing from small tubercles ; the 
tubercles on fourth, fifth, and ninth segments being 
often tinged with carmine, with a faint indication of that 
colour upon the others; in some of the larve these 
tubercles are very indistinct; a ridged sub-spiracular 
yellow line; spiracles very small and pale yellow; the 
twelfth and thirteenth segments somewhat flattened, 
and, from the dorsal surface of the latter the larva has 
the power of emitting two short whitish tentacles, the 
tips of which are furnished with a whorl of minute 
bristles; head pale amber colour, mouth darker, with a 
dusky round dot on each side of it. The tubercles on 
third and fourth segments are double. The half-grown 
larve are of a light greenish yellow, with a dark pulsa- 
ting dorsal stripe, and very faint indications of dorsal 
tubercles. The larva feed upon the flowers and flower- 
buds, and also upon young leaves, eating holes from 
beneath in the centre of the leaf, but do not penetrate 
through the upper cuticle. When full-grown they attach 
themselves to the underside of a leaf, or to a stem. ‘The 
chrysalis is from 10 to 11 mm. long and much re- 
sembles a chiton ; the abdomen is considerably depressed 
and ridged laterally; the segmental divisions are clearly 
marked and ridged. The colour varies, those attached 
to the leaves being greenish yellow, or pinkish brown, 
while those attached to the stems are nearly black, and 
they are all more or less sprinkled with dark dots and 
pencilings; spiracles pale yellowish enclosed in a red- 
dish ring. 
The first butterfly appeared on our passage home at 
Batavia, on June 9th; the last in the English Channel, 
on August 26th, the day before we arrived at Plymouth.
