[Vol VI. 
Stage V. —Elongate, anterior end rounded, posterior pointed but 
without a well formed tail. Dorsal space moderate, even, but little 
arched, lateral broad, subventral moderate. Ridges low tubercular, 
with distinct dark setae. Skin clear granular, whitish; all very trans¬ 
parent, green pigment only in the upper half of lateral space, none in 
dorsal space which appears darker from the food showing by transpar¬ 
ency. A waved subdorsal line, bent inward on the interspaces, free at 
the ends. Depressed spaces not visible, except faint white rings to 
represent the lateral ones (4). Length, 3.8-5.8 mm. 
Stage VI .—Narrowly elliptical with a pointed tail; setae short, black, 
distinct. Pigment in the upper half of lateral space, the rest of the 
body clear green from the blood, translucent and whitish in the edges. 
A wavy yellow subdorsal line, free at the ends. Dorsal depressed 
spaces (1) very faintly indicated by whitish dots, visible centrally only ; 
lateral (4) as large intersegmental white rings, but probably at least 
the glands of all the spaces (i)-(8) are present, as drops of moisture 
were observed in the appropriate position of them all in the larva under 
observation. Skin granules rather coarse, dense, but not contiguous, 
the depressed spaces not differentiated. Length, 5.0-8.5 mm. 
Stage VII .—(Plate I, fig. 9, 10). Shape as described. Patches 
of pigment in the dorsal space surround the rings of depressed spaces 
(1). Light yellowish green, lateral edge clearer, dorsal space darker. 
A waved, narrow, yellow, subdorsal line, free at the ends; tail 
reddish brown above. The absence of pigment in the dorsal space 
makes it look hollow, though it is really flat. Six of the depressed 
spaces (1) are visible as white rings, around which more or less light 
emerald green pigment forms in rings, transverse bands or even 
filling all of the dorsal space (Plate I, fig. 10.). The subdorsal 
line is composed of a series of intersegmental, inwardly lunate, joined 
yellow marks. Lateral space to lower edge of depressed spaces (4) 
pigmented light green, (4) large pale rings with dark centers. A trace 
of pale dots along lateral ridge intersegmentally. Tail long, pointed ; 
setae very small, pale. Skin granules rather large, somewhat irregular, 
not quite contiguous, at the largest depressed spaces, (1) and (4), less 
distinctly granular over the slight hollows. A broken white subventral 
line. Length, 7.1-13 mm. 
Cocoon and pupa as usual. 
Food-plants. —Linden, witch-hazel, hop-hornbeam, beech, maple, 
black birch, wild cherry, sour-gum, black oak, chestnut, hickory and 
Leucotho'e racemosa, have been observed.
