LYCLENA II., III. 
After second moult: length .12 to .16 inch; general shape as before, but 
the dorsum is now covered from 3 to 10 by a low, broad, continuous, tubercu¬ 
lous ridge, cleft to the body at the junctions of the segments, the anterior ed«-e 
on each segment depressed, the sides incurved; 2 is more flattened than before 
and the outer border is thickened into a rounded rim, leaving within the curve a 
flat, depressed space; surface pubescent; about the base a fringe, as before and 
a few short hairs on summit of dorsum; color in spring, pale green, the dorsum 
whitish, usually with a median reddish line or stripe from 3 to 10, often macular- 
in summer, variable, buff or pale green, without spots, the second segment brown • 
Ill some examples the dorsum and sides are mottled with dark green and brown • 
occasionally one is wine-red throughout, or red with a white basal stripe and 
white along the edges of the dorsal tuberculations; in fall, dull green, more or 
less marked brown. (Fig. d.) Duration of this stage 3 to 4 days. 
After third moult; length .18 to .2 inch; in shape nearly as before, the dor¬ 
sum higher, segment 2 more produced and flattened; the long hairs on dorsum 
ost but the basal fringe as before; color variable, as in previous stage. (Figs e 
to e\) Duration of this stage 3 to 4 days. 
After fourth moult: length .25 to .3 inch; maturity is reached in 3 to 4 
clays. 
Mature Larva. — Length in spring and fall, .4 inch, in summer, .5 to .55 inch • 
Shape long oval the base flat, dorsum high and sloping both ways from about 
the middle, the last segments flattened; the second segment is bent forward to the 
plane of base, produced, flattened, and wholly conceals the head when the larva is 
at rest; viewed from above the sides are nearly parallel, the two ends (segments 
- and lo) are about equally rounded ; from 3 to 10 inclusive is a dorsal ridge 
made ol tuberculous processes closely joined at the junctions of the segments, the 
lout edge of each depressed, the posterior edge raised and rounded, so that each 
process seems to lit into the next preceding; 2 is depressed in middle, and 
the whole outer edge is thickened and rounded; color variable, in spring, usually 
as follows: the ridge whitish, often stained red, or it is brown, light or dark ; the 
upper part of side olive-green, with a darker green, or sometimes a dull red 
patch along the posterior edge of each segment; below this area pale green, and 
along base more or less brown ; 11 to 13 are mottled in shades of green, often 
v ith brown, and 2 is either green or brown; if the latter, then with a brown 
patch in the depression; under side pale blue-green; color in summer, sometimes 
yellow-white or all delicate green, 2 being brown; or the ridge is light green and 
the sides dark, often with brown patches over all; or light green, with a medio- 
dorsal macular deep green band, and a similar one along base ; or the whole sur¬ 
face may be wine-red, or even chocolate-brown; color in fall, green, with more or
