THE CANADIAN ENTOMOLOGIST. 87 



The larva, in escaping from the eg^, eats an irregular hole in the top, 

 and leaves the rest. The larva feeds by making pits in the leaves or seed- 

 pods of its food-plant. My larvae hibernated about the middle of August. 

 some three weeks after hatching. I kej)t the larv?e over winter by placing 



them in a small tin box, which I put into a baking-i)owder can fastened 

 outside a window, on the north side of the house (our winter storms come 

 from the south). 1 previously punched holes in the bottom of the can, 

 giving a free circulation of air, and yet keeping out the rain. In this way 

 I succeeded in keeping alive practically all of the larvae. The larv^ne 

 moulted the following spring from March Qlh to nth, bringing them into 

 the third instar. i\bout a month later they })upated, and the adults 

 emerged at the end of two or three weeks. Thus the total time spent from 

 the hatching of the larva to the appearance of the adult, not counting the 

 six months of hibernation, is from 65 to 70 days. In moulting, the skin 

 becomes loosened a segment at a time, from the posterior end forward. 

 After a few minutes, a split appears cephalad, extends back and divides, 

 forming a Y-shaped opening. Then the larva slowly crawls out, the old 

 shiell of the head falling off. As the larva comes out, the eversible sacs 

 are extended, a skin apparently coming from them also. 



£^!^^ — Diameter, 0.65 mm.; height, 0.25 mm. Of the ordinal y 

 Lycaenid shape, covered with a raised network forming polygonal cells, 

 each cell having a rounded process at each angle. Cells smallest about 

 the base of the egg, becoming gradually larger at the sides, and again 

 somewhat smaller about the micropyle, which is slightly depressed. Colour 

 light pearly bluish-green, the network lighter. 



Larva, First ///^/ar.— Length, a little over i mm. Slug-shaped; 

 yellowish-green ; head black.' A row of long, light brownish hairs on each 

 side of dorsal line, from segments 2 to 11, one hair to a segment in each 

 row, except segment 2, which has two hairs on each row. A secondary 

 row of smaller hairs, laterad of each primary row, one hair to each row 

 on segments 2 to 9. A number of irregularl}' placed hairs on first 

 segment, about and on the cervical shield. A fringe of long hairs on 

 lateral margin. Toward the end of the instar the body becomes darker 

 green, with minute dark dots on dorsal surface, and the dorsal line dark 

 green, with a light line on each side. 



Seco7id Instar. — Length, 3.75 mm. Colour silvery bluish green 

 dorsal line dark green ; body surface scattered with minute dark dots, 

 except along the dorsal line ; some very indistinct oblique lateral dashes
