204 THE CANADIAN ENTOMOLOGIST. 



whole surface irregularly dotted with black ; and from most, but not all, 

 of the dots come white hairs, those on dorsum curved back, those nearer 

 base curved partly downward and partly back ; head obovate, long and 

 narrow, smaller in proportion to 2nd segment than at last stage, and partly 

 concealed, even when active, in second segment ; color black. 



After SECOND MOULT; length .12 inch; broader and flatter than 

 before ; on each side of the narrow dorsal ridge a slightly raised edge, 

 caused by the tubercles ; at the base of the body a fold, and the hairs 

 from this and the ridge are longer than elsewhere ; whole surface finely 

 pilose ; color green, but with a rusty tint caused by the numerous reddish 

 points ; above the fold these take the form of a line or slight stripe ; at 

 this stage the division of the segments becomes distinctly apparent. 



After THIRD MOULT ; length .20 inch ; color clear apple green, the 

 crests of the dorsal ridge, and also the fold at base, whitish ; on either side 

 of the white line thus caused at the fold, on several of the segments after 

 the middle, but not on the two last, is a reddish line ; there is also an 

 indistinct double oblique line of pale green on side of each segment ; 

 head as at last stage. 



After FOURTH MOULT; length .36 inch, greatest breadth .10 

 inch ; onisciform, high anteriorly, the back rounded and sloping to last 

 segment, which is much flattened ; both ends (when the head is retracted) 

 rounded equally, or nearly so ; each segment rounded dorsally ; the 

 whole upper surface covered with fine white hairs ; color emerald green 

 with very many yellow tuberculous points ; along middle of dorsum a 

 deep green stripe in a depression ; at base a whitish line edged with 

 vinous on three or four segments after the middle ; under side and legs 

 pale green ; head .025 inch in breadth, longer than broad, obovate, shining 

 black, seen through the 2nd segment when half protracted. 



CHRYSALIS ; length .26 inch ; greatest breadth .10 ; shaped much 

 like the mature larva, rounded at each end, tapering on the sides some- 

 what from segments 5 and 6 to head, roundly carinated dorsally, flattened 

 on under side ; the mesonotum but slightly prominent ; color emerald 

 green, except the abdomen both above and below, which is yellowish 

 green ; a dark green medio-dorsal stripe from end to end, and on either 

 side of this a row of small round black spots, nearly the whole length ; 

 much covered with fine white hairs : on the top and sides of the anterior 

 segments the hairs are conspicuously longer, and are arranged in tufts, and 

 similar hairs form a connected fringe quite round the abdomen.
