the largest of all, nearly square, its lower portion extending outward somewhat 

 toward j hind margin. In the discoidal space is an oblong longitudinal white 

 mark, its outer point touching the last mentioned white spot. Below these, in 

 centre of lower third of wing, is a similar longitudinal white mark resting on the 

 lower nervule. Hind margin is dark brown, without markings. 



Under side of fore wing presents the same white spot, but ground color is a 

 shade darker. The costa is of a lighter shade than ground color. The second- 

 mentioned " white mark " of upper side is replaced by a silvery dash of some- 

 what larger area. The interspaces at hind margin, excepting the three lower 

 ones, bear a triangular dash of grayish not at all prominent. 



Under side of hind wing is somewhat darker than fore wing. The nervures 

 and nervules are grayish. There is a small white spot in subcostal space, one- 

 quarter inch from base, and another of similar size in end of discoidal space. 

 The two upper interspaces have an indistinct dash of gray scales, one-third dis- 

 tance from upper angle to base, which are repeated in lower interspaces, but 

 are placed nearer hind margin. The triangular dashes of gray in the inter- 

 spaces of fore wing at hind margin are duplicated. The inner margin is 

 lighter brown than ground color. 



The specimen which I describe has been submitted to Prof. 

 E. T. Owen, Mr. E. M. Aaron, Dr. Henry Skinner, and Dr. Herman 

 Strecker, and has been compared with the collections of Godman, 

 Druce, Hewitson, the British Museum, etc. It was taken by Mr. 

 M. Abbott Frazar in 1888.
