and proceeds to the dorsal margin at the apex. The discal cell is -wide 

 towards the end and the subcostal comes down obliquely towards the 

 middle of the wing, from its second branch to its apical one. The cell is 

 closed by a curved discal vein which gives off two branches to the dorsal 

 margin. The median vein is nearly straight to the end of the cell, where 

 it is deflexed to the dorsal margin, after having given off two branches 

 from near the end. The median is furcate at the apex and attains the 

 dorsal margin about the middle. 



(This description is according to Dr. Clemens' system of nomenclature 

 of the neuration. A more intelligible description, with the sketch of the 

 wing before me, would be — median nearly straight to the end of the cell, 

 which is widest near the end and is closed by the oblique curvature of the 

 costal vein to its junction with the median. Nine branch veins are given 

 off from the cell, the first from about the middle of the subcostal and 

 three others from about the end of the cell, all going to the costal margin, 

 the last one at the apex ; four other branches to the dorsal margin from 

 about the end of the cell, and one from the median before the end of the 

 cell.) 



Posterior wings lanceolate, or rather wedge-shaped, the costa slightly 

 excised from the apical third ; the costal vein attains the margin at the 

 excision • the subcostal distinct from the end of the cell to the apex, faint 

 before the end of the cell ; the discal cell closed by a faint rather long 

 oblique discal vein which gives off two branches to the dorsal margin, the 

 superior branch being faintly continued through the cell to the base, the 

 inferior branch is given off close to the median, which is three branched, 

 the two last being approximate in their origin ; submedian distinct ; cell 

 very wide.

Palpi reddish brown ; antennae dark brown, annulate with white 

 Primaries bright golden \ a reddish brown spot margined behind with 

 white crosses the base and is continued along the extreme costa nearly to 

 the apex. About the basal fourth is a large costal red brown spot white 

 margined behind, and about the middle is a larger one margined with 

 white before and behind ; opposite the space between these two spots is 

 a larger dorsal red brown spot, white margined before and behind, its 

 white margin being continuous with the white margin of the second costal 

 spots. It is also connected with each of the costal spots by a narrow red
