THE GOSSAMER-WINGED BUTTERFLIES 



these spots are more or less surmounted and embraced by 

 orange lunules. Beneath in both sexes the wings are pale 

 hoary slate gray. On the fore wings the medial cross-veins 

 bear a black spot encircled with white ; beyond this there is a 

 series of six similar spots. Between this series and the outer 

 margin there is a series of pale orange or whitish spots bor- 

 dered within and without with black. The hind wings are 

 marked in a similar manner; there are eight spots in the 

 series next beyond the medial cross-veins, and on the base of 

 the wing there is a transverse series of four or more less dis- 

 tinct black spots. The orange spots are more distinctly 

 marked than on the fore wings, and the outer black border 

 of these spots is more or less covered with pale metallic green- 

 ish scales. Expanse of wings one inch. 



This is a Canadian butterfly ; but it occurs in certain parts 

 of New York and probably in New England. The species 

 is two-brooded. 



Caterpillar. — Length, about one-half inch. Color pea- 

 green with a yellowish tinge on the sides of the abdomen. 

 Body is sparsely covered with short hairs and the body walls 

 are rather transparent. 



Food-plant. — Wild lupine. 



Surely it must be one of Mr. Scudder's com- 

 pensations for a lifetime of infinitely patient and 

 loving research in the habits of butterflies that 

 this beautiful little creature bears his name. Far 

 better to have a name preserved on glinting 

 wings than on tablets of stone, for stone crum- 

 bles in the course of time ; but every summer
