Body dull rusty black; the head rather smaller than the 2d segment, 

 and streaked lonp-itudinally with sordid white. The sides of the seg- 

 ments are produced into a long, blunt tubercle, from which spring out 

 like a fan a series of very long hairs, some of which are ciliate, others 

 with a fan-like termination All the segments dorsally have 2 spinose 

 tubercles, those of the third segment being very much larger than the 

 others. On the sides of 4 is a broken whitish patch; on 8, another, 

 which spreads over the dorsum; and on 11 and 12 others less distinct. 

 The underside of the body, including the legs, is reddish flesh-color, 

 with a velvety black spot between the legs. At the juncture of 4 and 

 5 is a fold, velvety black beneath, only visible when the larva is in 

 motion.

TOLVPE LARICIS. Fitch. (No. T^Z?) 

 Larva. (After 3d moult.) 



Entire surface rusty brown, the segments are corrugated in large 

 folds, each bearing dorsally transverse tubercles, those of the 4th and 

 9th being the largest. The lateral ciliai are attached to tubercles as in 

 /. velleda, but are much shorter than in that species. 



(After 4th moult.) 



Rusty brown, paler than /. velleda, with the segmental tubercles 

 similar in shape, but much smaller, and with the white blotches less 

 distinct.

Head dull chestnut brown, with some darker markings; body wholly 

 yellowish green, with slight brownish tint. On 7 and 8 is a broad brown 

 triangular patch, the mark being continued slightly reducing in size to 

 the anal segment. Each of the segments bears brownish tubercles, 

 with short spinous hairs; those of No. 5 have 6 tubercles, of 8 and 9
