THE GOSSAMER-WINGED BUTTERFLIES 



The Least Purple Hair-streak 

 Calycopis cecrops (Cal-y-co'pis ce'crops) 

 Plate XXXIV, Fig. io, ii, 12 

 The upper surface of the wings is a rich blackish brown, in 

 some specimens entirely so, in others it is tinged with blue on 

 the fore wings, and heavily marked with blue on the hind 

 wings. The lower surface is pale slate brown, with a con- 

 spicuous red band on the outer half of the wings. This band 

 is edged without by a narrow black line, which in turn is 

 edged by a broader white one. Expanse of wings about one 

 inch. 



Caterpillar. — Unknown. 



This species varies greatly in color, the blue 

 that suggested the common name being absent 

 in many specimens. The special beauty of this 

 minute species lies in the bright red band that 

 marks the under side of the hind wings. 



The Brown Elfin 

 Incisalia augustus (In-ci-sa'li-a au-gus'tus) 

 Plate XXXV, Fig. i, 2, 3 

 Three of our Eastern hair-streaks represent the genus Inci- 

 salia. These are dark brownish butterflies, in which the fringe 

 of the outer margin of the hind wings is slightly prolonged at 

 the end of each vein, giving the wings a scalloped outline; 

 but there are no prominent taillike prolongations of the wings 

 as in all the hair-streaks described above. In the outer third 

 of the inner margin of the hind wings there is a deep rounded 

 excision, producing a conspicuous lobe at the anal angle.
