[FLETCHER & GIBSON] SOME SPECIES OF CANADIAN LEPIDOPTERA 39 
the stigmatal band is marked with streaks and dots of brown, white and 
dark green. The dorsal and lateral stripes are inconspicuous and have 
almost disappeared. The stigmatal band is creamy yellow suffused with 
bright purple. Ventral surface greenish-white, dotted with white. 
Tubercles very small, black and inconspicuous, iv behind the spiracle; 
sete pale.  Spiracles elliptical, blackish-yellow, rimmed with black. 
Thoracic shield grayish. Thoracic feet concolorous with venter, 
brownish at tips, and rather translucent; prolegs also concolorous with 
venter; claspers dull reddish. Just above the claspers the prolegs are 
purplish. As the larve reach maturity the purplish sheen over the whole 
skin becomes less intense. 
Length of mature larva 32 mm. at rest, extended 36 mm.; segments 
all about the same width, 4.2 mm. 
On the 29th July a few of the larvæ entered the earth for pupation, 
others buried on the 30th and August 2nd and 4th. 
Pupa.—Length 15-16 mm., width at widest part 5 mm.; dark 
chestnut brown, shining; thorax and wing cases wrinkled, abdominal 
segments coarsely pitted on anterior half and minutely pitted on posterior 
half. Cremaster rough, bearing two straight spines and a wartlike 
protuberance on either side below the spines. 
Unfortunately none of the moths emerged. The species is not 
abundant in the Ottawa district, but specimens have been taken occa- 
sionally about the middle of June.
