240 BUTTERFLIES 



costal and a humeral vein on the hind wings) these Metal- 

 marks may be known by their minuteness and the bright 

 metallic markings on the brown wings. 



Both our eastern species belong to the genus Calephelis. 

 The Small Metal-mark {C. caenius) has been collected 

 in Florida and Georgia. The wings are rusty red on both 

 surfaces, brighter below than above, and marked with 

 blackish spots that almost converge to form stripes; in 

 addition to which there are, beyond the middle of each 

 wing, two lines made by special scales that glisten with a 

 steel glitter. The wings expand only about three quarters 

 of an inch. So far as I can learn, the eggy larva, or pupa 

 have never been described. 



The Large Metal-mark is called by science Calephelis 

 borealis, but it deserves the latter name only in the sense 

 that it is more northern than its allies. It has been col- 

 lected as far north as New York and Michigan, but it 

 seems to be very seldom found, at least in eastern regions. 

 It expands a little more than an inch. The general color 

 of the wings is yellowish brown, marked with blackish dots 

 and lines, together with rows of steely spots on the under 

 siu*face. In this case also the life-history is unknown. 



THE GOSSAMER-WINGS 



Family Lycaenidae 



The daintiest and most delicate of all our butterflies are 

 included among the Gossamer-wings. Their bodies are 

 small and slender, their antennae ringed with white and 

 almost threadlike, their wings thin and of exquisite beauty. 

 Many of them are marked with the slenderest of tailed
