Anterior wings deep velvety black, all the veins diffusely striped 

 with flesh color, which also prevails round the entire margin of the 

 wings, most conspicuously so in the $ . From the base of the wing, 

 below the median vein, a broad flesh-colored stripe runs to the external 

 margin, becoming distinctly furcate above the internal angle, and upon 

 which, in the terminal half of the wing, rests a series of identically 

 colored bands resembling the letter K with the straight stroke turned 

 towards the base of the wing and bent, and the upper limb attaining 

 the outer margin below the apex, and thence reflected to the costa 

 between the transverse band and the apex ; a broad straight band 

 crosses the disc from the costa to the median vein, sometimes apparent 

 in the interspace below the latter. The color of the foregoing markings 

 varies from flesh color to dirty yellowish white, and they are broadest 

 and most conspicuous in $ . 



The posterior wings are red, of a more or less pinkish shade, some- 

 times inclining to orange. They are marked with black spots, which 

 vary considerably in size and number. When all present they are 

 eight in number (fig. i), viz. : one on the costa; a median row of three, 

 consisting of a discal spot, one at the base of the 4th median, and 

 one on the sub-median vein ; and an outer row of four, consisting of 

 one irregular fused spot at the apex, one on the 2d median, one on the 

 4th median, and one at the anal angle on the sub-median vein. The 

 latter varies greatly in size in both sexes though always present ; the 

 costal spot and the inner spot of the median row are often absent, 

 reducing the number to six ; and the spots are generally larger and 

 more intense in color in the ? . The black spots are sometimes very 

 narrowly edged with yellow ochre, more clearly so in $ than ? . 



Expanse of wings, i. 90-2. 50 inches. Length of body, 0.80-0. 90 inch.
