little dorsally above the bases of the tubercles in paired hollows. All 

 colorless. Setae Y-shaped in the subdorsal row on joints 4-1 1, the 

 front limb a little shorter than the back one (Plate VI, fig. 1) ; two seta? 

 on joints 3 and 13 ; a middle row of two on each of joints 3 and 4 ; a 

 single lateral row on joints 3-12. Tips of setse a little enlarged, not 

 distinctly swollen. Subventral setse very fine, obscure, all pale. Head 

 colorless, eye black ; body whitish, food greenish. Length, .9-1.4 mm. 



Stage II. — Narrowly elliptical, tail rounded quadrate ; dorsum 

 broad and flat, the subdorsal ridge forming its sharply angled edge. 

 Smooth, regular, all the depressed spaces (1) to (6) large and very dis- 

 tinct. Sides concave, lateral ridge smooth; subventral area retracted. 

 Latticed ridges covered with smooth, dense, frosted, appressed granules, 

 one row wide, uniform, not papillose anywhere. Setse absent. Color 

 opaque whitish; later distinctly pale green. Length, 1.3-1.8 mm. 



Stage III — Rounded, rather broadly elliptical, sides concave at first 

 so that the dorsum stands up as a broad ridge gently arching from head 

 to tail. Tail slightly notched at the sides, rounded. Depressed spares- 

 very distinct, (4) narrowly elongate. Latticed ridges beaded with clear 

 appressed granules, not generally over one granule wide in the narrower 

 parts. Bottoms of the spaces finely granular, dotted, the larger ones- 

 with shallow, saucer-like centers. Color green ; a yellow line appears 

 along the subdorsal ridge on joints 5-9, widened a little on each seg- 

 ment. Usually no other marking, but there may be a small, faint, or 

 even distinct dark red dot between the lines on joint 8, or surrounding 

 the depressed space (1) of joints 7-8. Length, 1.8-2.4 mm « 



Stage IV. — Rather narrowly elliptical; tail rounded quadrate. 

 Dorsum rather narrow, a little grooved at first. Lateral ridge extend- 

 ing beyond the subventral one. Depressed spaces large and sharp, the 

 latticed ridges scarcely more than one granule wide, but the granules 

 becoming wedge-shaped. All smooth, no setae. Color light green, the 

 yellow subdorsal lines reaching joints 5-10. The dorsal yellow mark 

 varies from a narrow yellow bridge on joint 8 to a red bar on joints 7-8 

 (see the plate of T. pallida, pi. IV, fig. 3) or even a rather large round 

 red patch, which does not encroach on the subdorsal lines. Length,. 

 2.4-3.2 mm. 



Stage V. — Shape as in the mature larva; tail rounded, scarcely 

 notched at the sides. Dorsum not broad, sides oblique, concave. Lat- 

 ticed ridges several granules wide, smoothly evenly granular, a little 

 frosted. Spaces finely shagreeened with a circular shallow saucer-like 

 centre. Color green, spaces not discolorous except a little yellow in
