THE entomologist’s RECORD. 
post-spiracular contrasts with the manner in which this 
tubercle dwindles in some species. They are especially large 
on 2.3 and 4, that on 2 almost suggesting a forward tuft as in 
Orgvia. On 3 and 4 is a dorsal lozenge of bright yellow, as 
also on II (the three pale segments), on the former it includes 
half the trapezoidal tubercles, on the latter it is a large 
escutcheon and includes both trapezoidals. The whitish lateral 
marblings are so much more pronounced on ii as to make 
that segment still very pale. 
In the 4th skin, the larva presents some resemblance to the 
full-grown larva, and in the 5th, there is little difference from 
the 6th skin, except that the colours are rather brighter. The 
difference in colouring is, in 4th and 5th skin, much greater 
between individuals than between the skins. One, even in 3rd 
skin, has a yellow escutcheon on 3, 4, 6, 7, 8, 9 and 10, including 
the anterior trapezoidals, with a small patch in front of it and 
nearly all the tubercles yellow, but the majority have them 
black. 
In the 4th skin, 10-15 in length, some have the trape- 
zoidals yellow, some brown, very few black. The finest 
coloured have the trapezoidals 3^ellow, with a little yellow 
patch in front, except 5, which is dark, larger on 3 and 4, and 
on II forming the characteristic large escutcheon. The sides 
and dorsum black, covered with minute black hairs, the base 
of each surrounded by a greenish yellow ring (much modifying 
the general effect of the black ground colour), this coloration 
tends to run lateralty into lines, with the post-spiracular and 
sub-spiracular tubercles, and, being more abundant and pro- 
nounced, make the sides paler than the back. The escutcheon 
is free from these. The post-spiracular carry many long hairs, 
some larger than diameter of larva, nearly white and forming 
a deep fringe on each side. The sub-spiracular and marginal 
tubercles also contribute to this fringe. The head is black, 
but usualty with white line and patches similar to adult larva. 
In the 5th skin, this is about the same as in adult. The 
trapezoidals are }^ellow, each with one erect black hair, about 
as long as thickness of larva, the supra-spiracular very small, 
yellow, with one hair, the post-spiracular large, orange above, 
greenish-}^ellow below, with 10 to 20 long whitish hairs 
forming a lateral fringe, sub-spiracular and marginal smaller, 
pale-greenish and with numerous pale hairs, dorsal tubercles 
of 13 and 14 pale yellowish, of ii yellow, like escutcheon. 
The back is nearly black, changing on the sides to very light
