Plate I, fig. 8. 

 Hlngs above, in the male, blackish brown, with a cyaneous patch on both pair, corresponding in 

 outline with the wings and covering the whole surface from the base to a regularly denned dis- 

 tance from the anterior and posterior margins, the tint varying in brilliancy according to the 

 direction of the light; in the female the ground-colour is paler, the blue patch has a light azure 

 tint with a purple reflexion, is less widely diffused, especially in the posterior pair, and the 

 borders are proportionally broad : beneath the surface of the wings is brown in the male, with 

 a glaucous reflexion and gray in the female, and the markings, although of the same character, 

 are less prominent in the latter sex ; a brown band, commencing at the outer apical angle of 

 the fore wings, passes obliquely through both pair to the anal region of the hinder, where it 

 forms a gradual curve and terminates at the middle of the inner margin, having the outer edge 

 regularly defined and of a deeper tint, the inner gradually evanescent; the whole surface of the 

 wing, from the band to the base, is speckled or irregularly mottled with blackish brown, and 

 on each pair a very obscure stigma is scarcely perceptible; between this band and the posterior 

 margin is a double series of obscure dotted lunules facing each other with their concavities, 

 which in the hinder pair is more distinct, with gradually diverging lunules ; the margins between 

 the nervures, the inner series of lunules, the anal appendage at its inner edge, and the tails are 

 clouded with whitish dots. The body is blackish above and brown or gray underneath : the 

 antenna; are almost uniformly brown to the tip, which is ferruginous. 



Our museum contains one male and one female specimen, both in high state of preservation ; the former is 

 represented in the eighth figure of our first plate. It was obtained from the caterpillar by breeding : its 

 similarity, in the larva and pupa states, to Ami. Apidanus, will be pointed out in the subsequent remarks 

 on that species. Our insect exhibits, in the form of its hinder wings a marked peculiarity, on which a 

 section of this subgenus is founded ; the anal appendage being more lengthened than usual, and united with 

 the tail at the extreme angle of the wing.

Wings above, in the male, deep blackish-brown, the anterior with a large oblong brilliant cyaneous 

 patch, the posterior with a triangular one of the same colour, varying in both according to the 

 direction of the light to obscure purple, being separated from the margins by a regularly defined 

 border of the ground colour, which is broader at the inner margin of the hinder wings where the
