velvety-black, much darker than iu doubledayi ; on the fore wing 

 the pale streaks extend only into the apex of the cell. On the 

 hind wing the medial white markings are much shorter, the spots 

 at base of interspaces 4 and 5 and generally the spot in inter- 

 space 7 absent ; the subterminal and terminal vermilion spots 

 are much larger, and the tail is vermilion on its apical spatulate 

 portion. Antennae, head, thorax and abdomen as in doubledayi, 

 but the head entirely vermilion-red. 2 closely resembles the J , 

 fore wing broader, red markings on hind wing more crimson than 

 vermilion-red, often dull and irro rated slightly with black scales ; 

 medial white markings more extensive, the white mark in inter- 

 space 1 extends well below vein 1.
