animal eats it is not visible from above, the second segment entirely enclosing it. The second 
segment is half as wide as the following, the third, fourth, and fifth rapidly and progressively 
enlarging, the next three segments as rapidly decreasing in size, the remainder subequal. 
The second segment is quite unmarked, the third to the thirteenth have a subdorsal series 
of short oblique pale yellowish-green lines, between which the ground-colour is paler 
than the rest of the body; there is a dark green dorsal line; on each side of the 
ninth segment there is a prominent pure dead white somewhat diamond-shaped mark. 
The twelfth segment bears two most extraordinary structures, which consist of two diverging 
cylindrical rigid pillars, arising from the subdorsal region and of a pale green colour. 
When the insect is touched or alarmed from each pillar is everted a deep maroon tentacle 
as long as the rigid pillar, bearing at its end long parti-coloured hairs, the basal third 
of each hair being black, the upper two-thirds white. The maroon tentacle with its long 
hairs spread out like a circular fan or rosette is whirled round with great rapidity in a 
plane parallel to the body, its use being almost certainly to frighten away its enemies, as 
this larva, as far as I am aware, is not attended by protecting ants, and lacks the honey- 
gland on the eleventh segment present in so many lyczenid Jarvee which are affected by ants. 
PuPaA is almost as curious an object as the larva, reminding one of a lump of green jelly. 
Its colour is pale transparent light green, the wing-cases being bluish green and quite smooth, 
the rest of the pupa covered with tiny pits, giving it a rough appearance under a magnify- 
ing glass. It is entirely without angulations or processes, its widest portion is the very 
broad and flat base on which it rests, its length is about 7% of an inch, breadth 5, height 1%, 
the anal end produced into an obtuse point. There is a conspicuous heart-shaped pale ochreous 
mark on the top of the thorax, the pits upon it above-mentioned being filled in with reddish 
pigment, there are also three regular rows of tiny ochreous dots on the abdominal segments on 
each side, the divisions between the segments hardly visible. I made the following notes when 
breeding this species. June 24th. Eggs laid. June 27th. Larvee hatched, placed on young leaves 
of Derris scandens, Benth. (they also eat Heynea trijuga, Roxb., in Calcutta). June 28th. 
Larvz grown enormously. They eat only the young leaves, and only the parts near the stalks 
and midribs, perforating them with holes, they also eat the young stalks and flower buds. 
June 29th. Changed skins to-day. When first hatched the larvee are pale ochreous and 
hairy, just before changing their skins they turn green, and are without any protruberances, 
after the first moult they are quite naked, green, with two black horns on the twelfth seg- 
ment. Before changing they fasten themselves with silk to a leaf on the underside near the 
midrib. June 30th. Larve now eating edges of leaves. July Ist. Changed skins again, 
appearance much as before, only that they bave a kind of white saddle-mark on the ninth 
segment, horns the same colour as rest of body. They devour their old skins. July 3rd. 
Changed their skins again to-day, colour chocolate-brown, marked with green and white. 
July 5th. Probably changed their skins again to-day. Colour green, They now eat the 
young green stalks. July 7th. Changed to pupe. Before changing they lose all their bright 
colouring and markings, becoming a dull uniform green of the same shade as the leaves of 
their food-plant. Butterflies emerged in three or four days, In Horsfield and Moore’s 
Catalogue the larva of C. ¢hetis is portrayed with numerous vermilion markings on the dorsal 
region, and the pillars also of that colour, the white mark which is so conspicuous on each 
side of the ninth segment not being shown at all. 
I possess numerous examples of C. ¢hetis from Bholahat in the Malda District, from 
Calcutta, Barrackpore, Orissa, Ganjam, Karwar, Bombay, Poona, North Canara, and Ceylon. 
Typically, I can distinguish this form from the next species, C. arcuata, Moore, by the inner 
edges of the black margin at the apex of the forewing being nearly at right angles, in 
C. arcuata the inner edge is evenly rounded. The inner edge of the black border on the 
costa is sometimes jagged and sometimes even, and cannot be used as a distinguishing 
character. In Ceylon it occurs in the“ Eastern Province between Kandy and Trincomalee 
in forest land, Taken in August while settling on the ground” (Hzéchison). “ Kandy. 
Rather scarce” (Wade). Mr. G. F. Hampson writes: “It is a rare species on the
