in the intervals between the veins. The first segment of the 
abdomen is covered with long gray pile; the remaining seg- 
ments are fulvous brown, withadouble row of black blotches 
along the middle. 
“TLarva.—Length, when full grown, is two inches. The 
general color is a reddish drab, ornamented with numerous 
irregular longitudinal stripes of a reddish hue, with varied 
yellow and bordered with jagged lines of black. Four of these 
bands are continuous on the back, but vary greatly in width. 
On the sides they are much interrupted, the stripe below the 
spiracles being broken up into irregular patches. That im- 
mediately above the spiracles is regularly interrupted, disap- 
pearing at the middle of each segment. On the last two seg- 
ments all the bands are much interrupted and very irregular. 
The dorsal stripes are confluent a little behind the middle of 
each segment, from the fourth to the eighth, with the excep- 
tion of acentral stripe of the ground color, by which all the 
transverse lines are broken. These confluent band-like areas 
of the longitudinal stripes, are, at first, yellow, but all 
change to a russet at the last moult, except the anterior 
one, which remains a bright lemon-yellow. The surface is 
smooth with the exception of a transverse row of about five 
black hairs to each segment, each arising from a minute 
tubercle. There is also a prominent tubercle behind each 
spiracle (excepting that upon the first segment) bearing a 
black hair at its apex. This row of later tubercles is varie- 
gated with rose and yellow, and each is surmounted by a 
jagged black line, which includes the black spiracle in the 
area described by it. The ventral surface has the same 
ground color as the dorsal, and is similarly marked with 
longitudinal stripes, which are, however, less distinct than 
the above. The head is irregularly punctuate, patches of the 
punctures being black, giving the surface a mottled appear- 
ance. The general color of the head and first segment is 
lighter than that of the other parts of the body. The an- 
terior segment has a yellow front margin, interrupted in the
