THE CANADIAN ENTOMOLOGIST. 135 



Stage III. — Head black with short setae as in previous stage ; body 

 red-brown with a pale yellow dorsal stripe ; the mounds of the prothoracic 

 plate are more distinctly separate than in previous stage, the anterior ones 

 being kidney-shaped, each bearing 8-10 setae, the posterior one narrowly 

 oval with about 8 upright barbed bristles ; almost all these setae are black, 

 an occasional short white one being intermingled. Tubercles shiny, black, 

 prominently conical, tubercle I minute; tubercle II largest with about 

 12-15 spiculated black spines, those of the rear segment being longest 

 and inclined backward ; tubercle III with black setae ; tubercle IV with 

 two central black and about 8 white setae ; other lateral tubercles entirely 

 with white setae. Legs black ; prolegs colour of body. 



In late stages the body colour appears greenish marbled strongly 

 with red-brown and with central lateral portions of abdominal segments 

 showing traces of orange. Length, 9 mm. 



Stage IV. — Head as before ; body dark gray ; marbled with black, and 

 with a pale creamy, usually continuous, dorsal stripe. All tubercles black, 

 shiny, II very large ; lateral tubeicles, especially V and VII, shaded 

 prominently around the base with orange. There is considerable increase 

 in the number of setae, which are mostly prominently barbed. Legs 

 black ; prolegs orange. Length, 12 mm. 



Stage V. — Much as in previous stage. Pale yellow dorsal stripe 

 shows a tendency to narrow or disappear intersegmentally ; traces of a 

 broken yellow subdorsal line, composed chiefly of a strip of colour between 

 tubercles II and III. Tubercles I and II black, others either tipped with 

 orange-brown or entirely suffused with this colour. Spiracle orange, pro- 

 legs pale reddish. Length, 2-^ mm. 



Stage VI. — Similar to preceding. In freshly moulted specimens all 

 lateral tubercles show very strongly orange, becoming however later more 

 tinged with black ; dorsal stripe prominent ; subdorsal line almost obsolete. 

 Length, 29 mm. 



Stage VII. — We would refer to our previous article (Can. Ent., 

 XLIII, 259) for the description of this, the final stage. All larvae exam- 

 ined agreed excellently with the description drawn up from the spring brood. 



Apantesis place7itia A. & S. 



Ovum. — Practically identical with that of A. phyllira, deposited 

 promiscuously. 



Stage I.— When first emerged pale yellow with black head, turning 

 later dirty brown. Tubercles large, blackish, with long set^e, arranged as 

 m phyllira ; setae of I-III black, of lateral setae white ; prothoracic plate 

 dark, large, with apparently 6 black setae. Length, 3 mm.
