black scales, occupies the middle of the wings, and is divided into three unequal spots, by the median nervure 

 and by the base of the second median nervule. 



The secondary wings deep black, with the border between the dentations crimson ; a crimson space occupies 

 the same position, and is of similar form to that shown in the figure of the male, but it extends to the inner 

 margin, though of a less width. 



The under surface of the wings is similar to the upper side, but the space on the secondary wings is of a pinkish 

 white, with some scattered black scales anteriorly, which give the space the appearance of beiag less in size than 

 on the upper side. 



The vpidth across the wings is 4 inches.

Female. — The primary wings brownish black, having the summits clearer, and with eight minute spots of 

 white scales ou the outer margin ; a white space occupies the middle of the wing, which is divided into three 

 unequal spots, by the median nervure and by the base of the first median nervule ; the one between the first and 

 second median nervules is the largest, while that in the discoidal cell partakes of a triangular form. The second- 

 ary wings deep brownish black, with the outer margin between the dentations white ; a curved transverse band 

 of seven distinct and unequal spots of pale reddish bufp ; those at the anal angle are scarcely separated by the sub- 

 median nervure, which gives them an appearance of one large subquadrate spot ; the third and fourth are the 

 largest and oblong ; the fifth is less and rounded, while the two next are small, especially the seventh ; these 

 spots are all far removed from the nervure that forms the discoidal cell. 



The under surface of the primary wings is very similar to the upper side, both in colour and marking. The 

 under surface of the secondary wings is similar to the upper side, but the seven spots are of a pinkish white.

Male. PI. VIII. f. 7. — The primary wings pointed and bluish black, with the summits clearer ; an oblique 

 subtriangular space of a rich greyish blue, which commences from nearly the middle of the inner margin and 

 reaches to the second median nervule. The secondary wings deep bluish black, with the outer margin between 

 the dentations of a pinkish white ; a large space of scarlet, with the anterior half of a brighter colour ; and this 

 space is divided into four oblong spots by the nervules, the first, second and third spots from the anal angle 

 touching, or nearly touching, the nervure that forms the discoidal cell ; there is also a minute scarlet spot above 

 the second subcostal nervule. 



The under surface of the primary wings is black, with the summits clearer. The under surface of the 

 secondary wings is deep black, with only four of the spots similar to those seen on the upper side ; they are 

 smaller and of a pinkish white ; there is also a pinkish white spot at the anal angle.
