52, THE ENTOMOLOGIST. 
3 in.long. Similar to previous stage, excepting the tubercles, 
which are of a delicate lilac-pink, bearing black bristles; head 
and legs ochreous, former speckled with brown, and a central 
V-shaped mark and black eye-spots. During the greater part of 
the day they rest at the base of the plant and under the leaves ; 
towards evening they ascend the leaves to feed. 
After fifth and last moult, fully grown, it measures about 
1} in. long. The body slightly tapers at each end. There are 
in all sixty-two rather long tubercles (spines), four on the first 
segment, two on the second, four on the third and twelfth; on 
all the remaining segments, fourth to eleventh inclusive, have 
each six spines; these run in longitudinal rows, being dorsal, 
subdorsal, and lateral; the first pair on the anterior segment 
are slightly longer than the rest, and project over the head, but 
curve gently backwards; the second and third pairs are only 
slightly curved ; all the other spines are straight. All bear 
numerous black, shining bristles, and each terminates with the 
same. ‘The outline of all the spines is undulating, the space be- 
tween each bristle being convex; most of the spines are of a 
semi-transparent, pearly, milk-white colour, with the bases more 
or less lilac-pink ; those on the first segment are wholly rose- 
pink, and the succeeding ones gradually become paler, while 
those on the anal segment are likewise rose-pink ; all have dull 
rose or lilac-pink bases. The general ground colour of the body 
is olive-brown, being composed of a cream-coloured ground, 
finely mottled with dull black, forming an irregular chequered 
pattern ; the ventral surface is much darker, mostly of a deep 
olive-brown; there is a medio-dorsal cream-coloured longi- 
tudinal stripe, divided by a fine blackish line; on each segment 
bordering the stripe is a conspicuous, bold, velvety-black mark, 
divided in the centre by the dorsal spine; the anterior portion 
is quadrangular and posterior half triangular ; a slightly oblique 
elongated mark below and behind each dorsal spine excepting the 
first ; along the side is a subdorsal series of dusky markings, 
bordered on each side by a cream-coloured line forming a wavy 
band, broken up by the subdorsal spines; below each of these 
spines, surrounding the spiracles, are bold black mottlings; the 
subspiracular spines are situated on the dilated lateral undu- 
lating ridge, which is dull milky white. The head is flesh- 
colour, freckled with brown; eye-spots black ; a rose-coloured 
spot on each side of the crown, which is brown in front, with a 
central \-shaped whitish mark outlining the head-pieces. The 
legs are coloured like the head ; the claspers are rich red-brown. 
The anal segment terminates in a conical point of a rust-reddish 
colour; on the ventral surface of this segment are warty emi- 
nences clustered with black bristles, as well as on the anal 
point ; the head and claspers are all bristle-bearing.
