from each tubercle in stellate form; the tubercles on the second and 
third segments, also the anal tubercle, are dark brown: in some of the 
specimens all the dorsal tubercles are tipped with dark brown instead 
of orange-red; head and prolegs brown; middle and hind legs or 
claspers the same colour as the body; spiracles light brown. 
On the 20th some dozen underwent the next moult; the tubercles 
were then of a light buff colour, the six bairs in stellate form much 
lighter colour and less rigid, with one silky long hair protruding from 
the centre of the tubercle; colour of the body much lighter, ap- 
proaching yellow; prolegs brown, the meso or sucker-legs covered 
with short brown hairs, not visible in any of the former stages; a 
curious V-form of slate-colour on both sides of the hind or clasper 
legs, and an inverted V quite white on the forehead. The day after 
this moult the dorsal tubercles were of a bright golden hue, and the 
next day two bands of yellow were visible along the six posterior 
segments on either side. Directly after the larva has emerged from 
its old skin, the light hairs on the tubercles Jie on the body most 
regularly in a diagonal position, forming a diamond-shaped mark 
between the dorsal tubercles. 
On the 24th the farthest advanced passed through another moult: 
in this there is a great difference in the larva; the dorsal tubercles 
are of a much more coppery hue, those on the first, second, third and 
fourth segments especially: the side tubercles have a bluish tinge, 
with the exception of those on the fourth, and sometimes fourth and 
fifth segments,* which are of a bright silvery hue; the spiracles are of 
a brown colour, with a just perceptible white rim; the first, second 
and third segments [? second, third, and fourth] are covered with short 
light rigid hairs; long silky hairs are dispersed over the other parts of 
the back; prolegs brown; meso-legs or suckers same colour as body, 
which is a beautiful green, covered with small rigid brown hairs; anal 
segment brown on the sides; the yellow line along the side above the 
spiracles more strongly developed. In this moult the body is more 
transparent. 
Just at this time I had to leave the Coucan and proceed to the 
Deccan: on the march | had great difficulty in procuring fresh leaves, 
so that, from being exposed to the sun and from want of fresh leaves, 
many sickened and died. As the Pentaptera coriacea is not procur- 
able in the Deccan, I had again to hunt for leaves that they would 
* I have no doubt that the silvery tubercle, in some cases on the fourth segment 
only, and in some on both the fourth and fifth segments, is a distinguishing mark of 
sex.—J. H.
