directly to the internal margin. The middle line is straight, and 
joins the inner end of the third before it reaches the internal mar¬ 
gin. About one-half the distance from the third transverse line to 
the posterior margin is a jagged, pale, transverse line extending 
across the wing. The posterior wings are pale gray, marked with 
two transverse lines, the inner of which is straight and the outer 
sinuous like that of the fore wing. Beyond this is an obscure sub¬ 
terminal whitish band. Upon the middle of the wing, between these 
lines, is a distinct black spct. The wing beyond the outer trans¬ 
verse line is more irrorate with dusky, the fringe pale with black¬ 
ened scales 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, with a double row of black blotches along 
the middle. 
Larva .— Length, when full grown, two inches. The general color 
is a reddish drab, ornamented with numerous irregular longitudinal 
stripes of a reddish hue, varied with yellow and bordered with jagged 
lines of black. Four of these bands are continuous upon 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 immediately above the spiracles is regularly interrupted, dis¬ 
appearing at the middle of each segment. On the last two segments 
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 exception of a central stripe 
of the ground color, by which all the transverse bands are broken. 
These confluent band-like areas of the longitudinal stripes are, at 
first, yellow, but all change to russet with the lajst 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 lateral tubercles is variegated 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 irreg¬ 
ularly punctate, patches of the punctures being black, giving the 
surface a mottled appearance. The general color of the head and 
first segment is lighter than that of the other parts of the body. 
The anterior segment has a yellow front margin, interrupted in the 
middle by the median stripe already described. The legs are ringed 
with black and yellow at the articulations, and are elsewhere more 
or less spotted with black. Upon the antepenultimate segment aie 
two prominent black tubercles, one upon either side of the median 
stripe, each bearing a stiff bristle at its apex; and similar bristles 
are scattered over the dorsal surface of the succeeding segments. 
The last segment with the corresponding prolegs is punctate vit 
black, and bears two smaller setose tubercles similar to those above 
mentioned. The preceding pair of prolegs are irregularly stripe
