Hind wings black, with violet reflections ; the base of 

 the wing washed with fulvous. There is a black spot in 

 the cell, an irregular row of yellowish spots beyond the 

 cell, and a marginal row of fulvous spots. Fringes alter- 

 nate spots of black and white. Under side of fore wings 

 fulvous, white along the costa, a marginal row of silver 

 spots enclosed in black crescents, and some silver on the 

 costa and near the apex. The black of the upper side 

 repeated. Under side of hind wings yellowish brown,

 rounded at the base, the sides well rounded, depressed at 

 the summit, marked vertically by about eighteen ribs,

 this. It is cylindrical, somewhat thickest in the middle. 

 Color pale yellow-brown, translucent ; each segment from
