Segment V: Arrangement the same; v much farther below the spiracle; vii and 
viii in a parallelogram on the venter, the outer of vii minute or absent, the inner 
equal to viii. 
Segment A^I: Arrangement the same; vii in an inverted triangular group of three 
exterior to the proleg; viii minute, on venter at inner basal angle of proleg. 
Segment VII: Arrangement the same; i and ii slightly smaller. 
Segment VIII: Arrangement the same. 
Segment IX: Arrangement the same. 
Segment X: Arrangement the same; iii irregular; iv below. and behind the spir- 
acle; vi smaller; vii and viii in transverse row of two on the venter, vii much larger 
than viii. 
Segment XI: Arrangement the same; i and ii forming a square when seen from 
above; iii, iv, and v equal, closer to the spiracle; vi smaller, closer to v; vii and 
viii in a row of two, equal. 
Segment XII: Arrangement the same; i, ii, and iii equal and smaller than iv; i 
and ii forming an inverted trapezoid seen from above and i, ii, and iii forming a tri- 
angle seen from the sides; vii and viii in a transverse row of two tubercles, of which 
vii is the larger. 
Segment XIII: Arrangement the same; viii double, situated at inner basal angle 
of anal prolegs.

Body slightly narrower on the three anterior segments and suddenly sloping 
behind on the eleventh segment. Ground color pale, translucent, marked as follows 
on each side of the pale yellowish median line: First, a line of reddish; second, an 
equal line of yellowish white; third, a broader line of reddish; fourth, a narrower 
line of yellowish white; fifth, a stripe of reddish; sixth, the pale yellowish stig- 
matal stripe, more or less interrupted in the center of each segment. Following 
these below the spiracles is an irregular brownish stripe. Under side of body pale, 
except for brownish marks descending from above. Orange spots generally visible 
except posteriorly. 
Head reddish yellow or darker, spotted with dusky markings which leave a more 
or less distinct inverted V-shaped mark on the front. Ocellar spots pale with dark 
margins, placed in a curved line. Mouth parts pale. Mandibles fine toothed, 
darker at the tips. Cervical shield dark, or pale with the margins darker; broad, 
with the front margin straight and the posterior edge concave, sides curved, pos- 
' terior angles truncate or obtuse; sometimes with paired line of spots near the median 
line; its disk transversely impressed behind. Anal shield much smaller, dusky, 
three or four sided, emarginate in front, its disk roughened. Legs black, bearing 
many stiff setee. Prolegs pale, their shields shining black, sometimes paler. The 
anal proleg with an inverted V-shaped marking on its shield. Prolegs about equal 
in size, first pair slightly larger. Crotchets or claws consisting of at least twelve 
pieces. In locomotion, larva humps segments I and II of abdomen. 
Tubercles nearly the same as in Stage II, much larger and their setse larger and 
stiffer. The margins of the tubercular areas quite irregular and the smaller tubercles 
circularly roughened. On the cervical shield the two middle tubercles of the pos- 
terior line are nearer the median line and a little farther forward. On segments I 
to III, vi is larger and circularly roughened. On segments IV and V, iii is largest, 
iv and the second of vii each a little smaller and each fully five times larger and some- 
what blacker than the others in groups vii and viii. On segment X, ii is closer to 
the median line, so that i and ii form a square when seen from above.
