first generation may spin their oval, brown cocoons in leaves or 
other debris. The second generation presumably hibernate in the 
cocoon, adults appearing the following spring and depositing their 
eggs in minute slits on either or both sides of the petiole in series 
of 10 to 15 or even more, since Dr Lintner records as many as 28 
or 30 in one row. 
Description. The egg is pearly white, oval and about 1 mm in 
length. Its position is indicated by a slight swelling about I.5 mm 
long, the swellings being about I mm apart. 
Larva. The young larvae are about 6 mm long, have dark 
brown or blackish heads and pale green or yellowish green bodies. 
Partly grown larva. Length 1 cm. Head subglobose, jet-black, 
the most of the body being a very pale green with a conspicuous 
row of sublateral, subquadrate, black spots, a pair on each segment. 
The anterior portion of the body, namely the first thoracic seg- 
ment and the lateral tubercles on the 2d, 3d and the 11th seg- 
ments, particularly laterally, is variably tinged with pale orange, 
giving a very characteristic appearance. The larvae are rather 
thickly clothed with short, whitish setae arising from inconspicuous 
tubercles. True legs pale yellowish basally, yellowish transparent 
apically. The whitish transparent prolegs occur on the 2d to the 
7th and 8th and 9th abdominal segments, each segment also with 
a small, black, lateral dot. Anal plate subcircular, black with whit- 
ish setose tubercles. 
Full-grewn larva. Length 1.5 cm. Head jet-black. Body a deep 
yellowish orange, sparsely covered with fine, whitish hairs and with 
a conspicuous row of irregu- 
lar subquadrate lateral mark- 
ings, a pair on each segment, 
and a substigmatal row of small 
REE triangular, black markings. The

posed of nine segments, the first two short, the others long, slender
