The extended larva is 21 to 23 mm. long, of a nearly white color; 
head, smaller than first segment of body, somewhat oblong, slightly 
narrowed anteriorly, brown, with inverted Y mark, and sutures at base of 
mandibles, white ; at the juncture of the two branches of the Y mark, is 
a crescent shaped, white space, thickly blotched with brown ; the concave 
side of this space is downward, and the branches of the Y mark, in a 
measure, form its outline ; front depressed between branches of Y mark 
with a narrow, straight dark line, extending from their confluence to near 
frontal suture, lower margin strongly ridged. On each side of this dark 
line are three setigerous depressions, and there are several longer seta on 
the sides and vertex. Antenne rudimentary. Just above each of these 
is a setigerous puncture, and again just above these is a small semi-trans- 
lucent spot. Eyes wanting. Mouth parts, light brown; mandibles 
darker, stout, concave on inner side, bifid at tip, the lower portion being 
‘shorter and more curved, with a small, broad tooth on inner margin. 
Body, wrinkled, increasing from head to third segment, then decreasing 
to fifth, sixth to eighth equal, ninth larger, tenth still larger, eleventh 
smaller, twelfth much smaller, sub-convex and cypeiform behind, with 
anal aperture in center of disc. The first ten segments are divided above 
by two transverse wrinkles, forming two long and one short transverse 
folds on each, the latter being placed anteriorly. The eleventh segment 
has but one wrinkle, and the twelfth none at all. The first segment is 
larger than the head, with light brown patch resembling a cervical shield, 
which is divided by a median, lineal white line, and, bearing on front 
and posterior margins, a transverse row of short bristles. There is also 
a cluster of four bristles at each end of the cervical shield, and between it 
and the spiracle ; on the second fold are two, small, light brown patches, 
divided by a dorsal, white line, each patch bearing a single bristle. ‘The 
second segment has also a transverse row of bristles, and besides there is 
also one placed singly on each side of a slight, medial depression. Seg- 
ments three to eighth with similar row of small bristles only, the ninth 
having a single bristle on each side of the fold near the middle of the 
back. The tenth segment has a row of larger bristies, and two on each 
side of fold. On the eleventh, the bristles are still longer, and inclined 
to form clusters at the sides, near the spiracles. On twelfih segment, 
the bristles form a semi-circular clusier. On each segment, except the 
second and twelfth, is a double row of obtuse, yellowish pustules, 
placed just below the spiracles, each bearing a few, short, scattering 
bristles. Between these rows of pustules is a deep, lateral groove, and, 
where this crosses the segmental wrinkle, a deep, quadrangular fossa 
is produced. 
Beneath, the feet are wanting, and their place supplied by pust-
