subdorsal ridge, one on lateral ridge of abdomen (Plate I, Fig. 4 ). a 
secondary seta; above the spiracle and the two of subventral row below 
it Upper seta; long, stiff, black at apex. Skin with sparse granules 
produced into slender spines, longest and most numerous along the 
ridges at the bases of the setae; a few distinct spines in the dorsal space, 
but in the lateral area mostly fine granulations only. Color translucent 
pale greenish, no pigment. Segments well marked. Length i toi.6 mm 
St a ae III. _Body moderately elongated, elliptical, more elongated 
than T. 'pallida. Skin very finely granular, frosted under a half-inch 
objective, which hardly resolves the fine granules; conical, clear, pointed 
tubercles, much larger than the granules, are distributed in a single row 
along the low, rounded latticed ridges, becoming pale secondary spines 
on the tubercles. Tubercles low and rounded, the subdorsal ones with 
two, lateral with one large, dark, stiff setae. Ridges prominent, normal. 
Color pale green, alimentary canal dark. Toward the end of the stage 
a faint yellow line appears along the subdorsal ridge and yellow dots in 
the dorsal depressed spaces (i); all the depressed spaces faintly shown. 
Length 1.5 to 2.6 mm. .. 
Stage IV. _Ridges well marked, tubercular, setae black. 
quadrate, composed of the last abdominal segment. Depressed spaces 
as in T. pallida , but ill defined, the separating latticed ridges obscure. 
Skin finely granular, the larger spinose granules few in number except 
on the ridges. Color light green, dorsum dark, translucent. A narrow 
yellow line below the subdorsal ridge, a series of yellowish dorsal rings 
in the depressed spaces (i), seven of them distinct; a row of latera 
whitish spots (4)- Length 2.5 to 4 mm. 
Stage V. _Elliptical, tail quadrate, dorsal space moderate, lateral 
broad, oblique, subventral small, retracted. Ridges only slightly tuber¬ 
cular. Latticed ridges low, with both coarse and fine granules as be¬ 
fore, the former becoming pale spines on the ridges, especially the lateral 
one (Plate I, Fig 5). Color yellowish green, a narrow, wavy, yellow, 
subdorsal line; yellow rings in depressed spaces (1), two yellow dashes 
in (4), separated by a green spot; the other depressions show as yellow 
dots. There may be a distinct dark green spot between spaces (1) and 
(2) in certain larva;. Length 3.5 to 6.7 mm. 
Stage VI. _ (Plate I, Figs. 2 and 3.) Ridges slightly tubercular with 
distinct black setae, but without secondary spines; shape elliptical, the 
tail quadrate as in the mature larva. Skin confused granular, the gran¬ 
ules resulting from the two kinds of the former stage, alike now except 
in size, somewhat flattened in the dorsal space and irregular.
