Primaries long and narrow, moderately arched ; hind margin slightly convex. 



Male. Expands from 1.75 to 2.25 inches. 



Ujiper side fulvous, obscure at l)ase ; both wings have broad lilaek hind mar- 

 gins which enclose more or less fulvous between the nervules of secondaries, and 

 at inner angle of primaries ; the marginal spots either lunular or serrate, often 

 confluent on secondaries as on primaries, and resting on the border ; the spots of 

 median row on secondaries narrow and confluent, forming an angular band, in this

Atlantis is readily distinguished from Aphrodite Ijv its smaller size, duller 

 color, broad black margins, confluent median Ijand of secondaries and color of same 

 wings below ; also by the longer and narrower fore wings. It is found in the 

 mountainous districts of New York and in British America at least as far north 

 as Rupert's House, Hudson's Bay, and Lake Winnipeg. Among the Catskill 

 mountains of New York it is not uncommon in certain localities, such as narrow 

 passes through the mountains and in the gn.ss fields, which in those places often
