THE CANADIAN ENTOMOLOGIST. 371 



Shige /K — Length 7.5 mm. General appearance, black hairy larvtv, 

 tubercles very prominent, some specimens having a yellowish dorsal stripe. 

 Of the whole batch of 7 i larvie, the dorsal stripe was only present in seven 

 specimens. In the majority of the other specimens just the faintest sign 

 of this stripe was to be seen, while the remainder were perfectly black. 

 Head 1.2 to 1.4 mm. wide, bilobed, shiny, brownish-black, sparsely covered 

 with long blackish hairs. Bristles from dorsal tubercles black, with a few 

 white hairs intermingled. The bristles from the stigmatal and ventral 

 tubercles in this moult are of a light rusty hue, in some specimens much 

 brighter than in others ; there are also a few black bristles from these 

 tubercles. The medio-dorsal tubercles on segments 5 to 12, inclusive, are 

 very small and black in colour, bearing two or three bristles each. The 

 dorsal tubercles are very large, and bear numerous black bristles- 

 Stigmata black. Thoracic feet shiny, jet black, covered with short reddish 

 and blackish hairs. Prolegs concolorous, rather translucent, light at tips. 



On the 7th July three larvae passed the fourth moult, and on the 8th 

 the majority of the remainder moulted. 



Sfage V. -Length 11.5 mm. General appearance, black larvae with 

 black tubercles, bearing short and long black bristles, with rust-red 

 bristles from tubercles on lower half of sides. Head 1.5 to 1.8 mm. wide, 

 depressed at apex, shiny, black, sparsely covered with short whitish and 

 long blackish hairs. The reddish bristles on dorsum of second segment 

 turn down abruptly over the face, and give it a brownish appearance. 

 The dorsal stripe has disappeared, and is not present in any of the speci- 

 mens. Bristles from dorsal tubercles black, with a few grayish ones 

 intermingled. On the 12th and 13th segments the dorsal tubercles bear 

 one or two long hairs, black in colour, tipped with gray. The bristles 

 from upper half of stigmatal tubercles are black, those from lower half, as 

 well as all bristles below stigmata, rust-red. Spiracles black, with a light 

 orange centre, with exception of those on 2nd and 12th segments, which 

 are wholly bright orange. Thoracic feet shiny, jet black, covered sparsely 

 with short rust-red bristles ; prolegs concolorous, lighter at tips, also 

 bearing short rust-red bristles. 



On the 14th July three larvae passed the fifth moult, and by the 17th 

 nearly all had moulted. 



Stage VI. — Length 15 mm. General appearance the same as after 

 the fourth moult ; the rust-red bristles on sides and dorsum of second 

 segment appear brighter. Head 2.0 to 2.4 mm. wide, of about the same
