subgenera but as an ability to discriminate these involves a knowledge of minuter anatomical 

 details, which is only possessed by specialists, the writer has not deemed it worth the while 

 in a little manual like this to go deeply into these matters. The old name Lycoena, which has 

 been in vogue for a century, and which is still applied to part of the group, is sufficiently 

 characteristic. It we were reviewing all the species of the world, of which there are many 

 hundreds in this assemblage of forms, we would be forced to use the minuter methods of classi- 

 fication. The eggs are turban-shaped; the caterpillars are slug-shaped, feeding on the petals 

 and bracts of flowers or tender terminal leaves; the chrysalids are short, rounded at either 

 end, supported by a silken girdle and closely appressed to the supporting surface. 



(1) Lycama couperi Grote, Plate XC, Fig. 2, cf, under side (Couper's Blue). 



On the upper side the wings of the male are pale shining blue with a narrow black border; 

 of the female darker blue broadly margined with dusky. On the under side in both sexes 

 the wings are brownish gray relieved with white spots, having dark pupils. Expanse 1.25 

 inch. It is a boreal form. 



(2) Lycoena aster Edwards, Plate XC, Fig. 3, tf, under side (The Aster Blue). 



On the upper side the male is pale lilac-blue, the female darker blue, with a submarginal 

 row of paler blue spots on the margin of the hind wing. On the under side the fore wings 

 have a dark bar at the end of the cell followed on the limbal area with a curved band of small 

 dark spots. This style of decoration is repeated on the hind wings, and in addition there is 

 a marginal band of pale yellow oval spots, each surrounded by a fine black encircling line. 

 Expanse 0.95-1.00 inch. The insect is known thus far only from Newfoundland.
