156 HYBERNIA AURANTIARIA. 
time a nearer approach is made to the appearance 
~ exhibited at full growth. 
When full-grown the larva is rather over one inch 
and one-eighth in length, in shape moderately slender ; 
viewed from above, it appears of nearly uniform 
stoutness throughout, but viewed sideways the seg- 
ments seven to ten are rather stouter than the rest; 
the head is broad, flattened in front, and rounded at 
the sides, so as to be equal in width to the second 
segment, which, together with the third and fourth, is 
a little flattened also; the fifth is more cylindrical, 
and hence has the appearance of being a trifle thinner 
than the rest ; the skin is tough, furnished with a few 
bristles, and the back of the second segment is glossy, 
suggesting a sort of plate there; a pair of rather con- 
spicuous warts on the twelfth segment. 
Probably there are variations more or less in the 
colouring, but the larve I had were alike, and might 
be roughly described as being of a dark purplish-brown 
with yellow markings; but to pick out the arrange- 
ment of the markings was no easy matter. The 
eround colour of the back was pale, dull, ochreous- 
yellow, and through it a number of fine brownish 
lines, not parallel throughout, but approaching and 
receding, so as to form a pattern; of these, two very 
fine ones through the centre of the back, enclosing a 
thread of the pale ground ; on either side of this pair 
another darker brown line, and then again another ~ 
wavy one, touching the broad, deep, purplish stripe 
which occupied the side from the head to the twelfth 
segment, on which it mounted up the back, and meet- 
ing the stripe from the other side, formed there a A 
mark pointing forwards, and bearing on it the warts — 
of the same colour; below the broad stripe a pale 
yellow thread, and below this a_blackish-purple 
thread ; in the spiracular region, the front of each seg- 
ment sulphur-yellow, the hinder part dull ochreous ; 
here also could be seen indications of two fine purplish 
lines, showing at the beginning and end of each
