 The t. a. and t. p. lines are bordered with yellow, and terminate on the 

 median nervule, enclosing a very bright brown space. The sub-mar-

 brown, with a few indistinct orange patches. At base of costa is 

 another obscure orange streak, bordered with brown. The reniform 

 and sub-reniform are fused together, and surrounded by a whitish hne, 

 bordered with black. The metallic mark is oblique from median ner- 

 vule, with a bent streak from about its middle, which again touches the 

 median nervule, the enclosed space being chestnut brown, with a few 

 black scales. Secondaries bright orange, with broad black border, 

 narrowest at the anal angle. Beneath, the wings are all orange, clouded
