108 THE CANADIAN ENTOMOLOGIST. 
When older, it becomes pale green, with two dark brown longitudinal 
stripes on top of the third and following segments, with a row of dark 
brown spots on each side of each line, and a black longitudinal line on 
each side. 
to. D. bimaculella. WN. sp. 
cae head, thorax and forewings shining dark purplish- oes or 
black. Extreme tip of palpi yellowish-white ; there is a large white spot 
on the disc just beyond the middle, and a white spot or streak which 
starts from the beginning of thé costal ciliæ, but does not attain the 
dorsal margin. Ciliz fuscous. Abdomen pale fuscous, each segment of 
the venter tipped with white. A/ar ex. 12 inch. Kentucky. Common. 
Larva unknown. 
tt. D. cercerisella. lV. sp. 
Palpi white, except the third joint, which is dark brown from the apex 
nearly to the base. Face, head, and anterior margin of the thorax, white. 
Antennz dark brown, faintly serrated towards the apex. ‘Thorax and 
anterior wings shining, soft, velvety black, dusted with a few ochreous 
scales which, in some lights, give it a bronzy hue. Three large snow-white 
costal spots, the first of which is the largest, extending to the fold ; the 
second is about the costal middle, and the third at the beginning of the. 
ciliæ. A white dorsal spot opposite the third costal, and about four 
small white spots forming a row around the apex; costo-apical ciliæ 
short, dark brown ; dorso-apical ones longer and silvery white ; a dark 
brown hinder marginal line at the base of the ciliæ. Posterior wings 
scarcely emarginate beneath the np, pale drab, faintly Hines with pink. 
Alar ex. 72 to 5% inch. 
The larva is very pretty. When young, it is snowy white; when old, 
the basal half of each segment, above, is pearly white, and the posterior 
half shining black, with a shining black band across the head in front. of 
the eyes, interrupted in the middle, and a transverse bow-shaped shining 
black streak on the vertex. ‘The true feet are shining black. ‘This is one 
of the few instances among the 7Zreina where the colours of the imago 
are indicated by those of the larva. It feeds upon the leaves of the Red 
Bud ( Cercis Canadensis), which it either folds or sews together. It is 
exceedingly abundant in the larval state, but is much infested by an 
ichneumonide parasite, so that I have been able to rear but a single 
specimen, and haye captured another.
