116 (October, 
The larve, which are hybernating at this stage, have turned gradually to 
almost a dull pale orange colour throughout, the head and spines (all of the same 
length) remaining shining black. 
After the next moult there is again seen the previous arrangement of colours, 
but rather brighter, the spines and head still black as before—the larva being 
about five-eighths of an inch in length. 
After another moult, it assumes the final dress; it is then three-quarters of 
an inch long—increasing afterwards to about an inch—tolerably uniform in bulk, 
but, when looked at from above, widest about the fifth and sixth segments, and 
tapering thence very slightly to the tail: the segmental divisions well defined ; the 
head rather notched on the crown; of the six rows of spines, the upper—or sub- 
dorsal—rows are rather stouter than the others, and the front pair of this row— 
which are the only spines on the second segment—are now rather more than twice 
as long as the rest, and, after tapering for some distance, become thicker again at 
their tips, and, standing. forward a little apart from each other over the head, 
remind one much of a pair of snails’ horns; on the third and fourth segments, 
there are but four rows of spines, and those finer than the rest; as a whole, the 
spines may be described as conical, thick, fleshy, shining, and semi-translucent, 
ochreous in colour, tinged with pink, and beset with fine pointed black bristles ; 
those spines on the second, third, and fourth segments being exceptionally tipped 
with black, while the two lateral pairs are whitish at the base. 
The ground colour of the full-grown larva is a velvety smoky-pink ; there is a 
dark brown dorsal line, which throughout its course expands and contracts twice 
on each segment: in front of each sub-dorsal spine and partially enclosing it, is a 
velvetty black spot delicately edged with whitish, while behind each spine is a 
blackish interrupted streak; immediately beneath the whole row rans a much 
interrupted dark brown line; broad black spots are placed also in front of the 
spines in the lateral row: the spiracles are black, set in ovals of a pinkish tint, 
rather paler than the ground colour; and below them, bearing on it the sub- 
spiracular row of spines, runs an inflated stripe of pinkish-red paler than the 
ground, showing faintly and interruptedly on segments three and four, but dis- 
tinctly throughout the remainder. The belly is of a deep pinkish ground colour, 
freckled with dark brown on the sides; prolegs pale pink, tipped with blackish- 
brown ; the anterior legs black and shining. 
Most of the lines and streaks are more or less broken by a sort of warty or 
granulated texture of the skin in places, each little wart being of the ground 
colour, emitting a minute soft hair, so that the body has a delicate and scattered 
pubescence. 
The pupa is suspended head downwards; it is about half-an-inch in length, 
thick and obtuse in front, the abdomen thickest in the middle, thinner near the 
thorax; on each side of this part the edges of the wing-cases project, thus forming 
a cavity; the tip of the abdomen, viewed in profile, is blunt and rather abruptly 
curved back to its pointof attachment; the eye- and antennz-cases well developed, 
but all angles rounded off; the sub-dorsal rows of spines of the larva are still 
represented by two rows of blunt spikelets—not very projecting —along the back of 
the abdomen. In colour, it is brownish-ochreous on the wing covers, brown on the 
abdomen and thorax, and darker brown round the concave part of the abdomen;
