NYSSIA LAPPONARIA. 13 
segments are six lemon-yellow spots (three on each 
side), and of the same form as in the previous stage, 
one being dorsal and forming a transverse mark, the 
other two on the spiracular line, one elongate trans- 
versely, the second round, and each having the black 
central wart emitting a short hair as in the previous 
stage; the head, legs, and remaining details being 
likewise similar. It rests in a straight attitude, with 
the head shghtly bowed, and the first three anterior 
seoments slightly arched, thereby drawing together 
the first two pairs of legs; a silk cord from the mouth 
is attached to the stem while the larva is resting. The 
second moult took place on the 6th June. 
Before the third moult, when twenty-six days old, 
it 18 nine-sixteenths of an inch long; the body is of 
uniform thickness and cylindrical; the ground colour 
is whitish with a hlac-grey tinge, becoming yellowish 
shortly before moulting; it 1s chequered with black 
markings that are arranged in longitudinal bands, 
which are medio-dorsal, subdorsal, superspiracular, 
and spiracular; the spiracular row is formed princi- 
pally of conspicuous black blotches, commencing on 
the fourth and ending on the eleventh segments. 
Immediately below these markings is a series of bright 
hght yellow markings running the entire length; the 
dorsal markings, as in the previous stage, are also 
bright yellow. The ventral surface is similarly 
coloured and lined as on the dorsal region, but rather 
uniformly darker; the head, legs, and claspers are 
erey, speckled and streaked with black. It generally 
rests in a straightened attitude. The third moult 
happened on the llth June, and directly after 
moulting the ground colour is a leght olive-yellow; 
all the markings are as in the previous stage, but 
brighter and more clearly defined. The head, legs, 
claspers, and anal segment are all of a clear pinkisb- 
white, speckled with pale olive, the colouring of these 
parts remaining such but for a short time. The cast 
skin is not eaten by the larva of this species.
