reJ, marked with a, great number of small dark transverse freckles, with two dark transverse strigit: across the middle, followed l>y an 

 oblique one extending from the costa to the inner angle of the fore wings, and from the outer to the anal angle of tlie hind wings. 

 The type is a native of the hottest parts of South America, and is very rare, the only specimens which I am acquainted with in this 

 country being the mutilated ones in the Linnasan and Banksian collections. 



The extraordinary Caterpillar is represented by Stoll, who informs us that it feeds on the leaves of the sugar cane in Surinam. It 

 has a reddish brown head with darker markings; the body is purplish brown, with yellow diamond-shaped spots down the back, edged 

 with darker and lighter flesh-coloured lines. The Chrysalis is pale brown with darker markings.

Genus XI. CCELITES. 



CcELiTES Boisduval J\fS. 



Body slender, finely hairy ; wings large, splendidly glossed with purple on the upper «ide ; fore wings subconcave ; 



hind wings i-egularly oval, ocellated beneath ; all the wings very slightly scalloped. 

 Head moderate-sized, finely hairy. 



Eyes naked. 



Labial Palpi rather small, very compressed, clothed with short scaly lialrs, elevated obliquely, but not reaching 

 the level of tlie top of the eyes, and pon-ected to a little distance in front of the face ; middle joint without a 

 dorsal tuft ; terminal joint minute, oval. 



Antennce scarcely more than one third of the length of tlie fore wings, slightly curved, very slender ; gradually, 

 but very slightly, thickened to the tip ; forming a very long club, but little thicker than the rest of the 

 antennas, composed of short, scarcely distinct joints, of nearly equal length throughout. 

 Thorax oval, finely hairy. 



Fore Wings large, triangular-ovate. Fore margin moderately curved ; apical angle rounded. Apical margin 

 more than two thirds the length of the costal, slightly emarginate, and very slightly scalloped ; hinder angle 

 rounded. Hinder margin about equal to the apical, nearly straight. Costal vein strongly swollen for some 

 distance at the base, extending to the costa opposite the extremity of the discoidal cell. Postcostal vein with 

 its first and second branches arising at some distance before the anterior extremity of the cell ; third branch 

 arising at about one fourth of the distance between the cell and the tip of the wing ; fourth branch arising 

 about half way between the cell and the tip, uniting with the costa before the tip ; the terminal part of the 

 vein extending to the tip. Upper disco-cellular vein arising rather beyond the middle of the wing, very short, 

 transverse : middle disco-cellular much longer, slightly curved, and directed obliquely towards tlie base of the 

 wing : lower disco-cellular longer than the middle one, rather angulated at the base, the lower part slightly 

 oblique, and directed to the apical margin ; uniting with the third branch of the median vein at a considerable 

 distance from its origin ; this third branch being slightly angulated at the place of junction, beyond which it is 

 regularly curved. Fii'st branch of the median vein arising nearer the base of the wing than usual. 



Hind Wings regularly oval. Costal margin curved. Outer margin slightly scalloped. Postcostal vein branching 

 at a considerable distance from tlie base. Upper disco-cellular short, curved, forming the base of the discoidal 

 vein : lower disco-cellular vein much longer, straight, oblique, terminating the narrow discoidal cell at the 

 middle of the wing in an acute angle, by its union with the median vein exactly at the origin of its third 

 branch, which is slightly curved. 



Fore Legs of the male very minute and feathered. Coxa elongated. Femur shorter than the coxa, rather 

 thickened at the tip. Tibia much shorter than the femur, veiy hairy. Tarsus extremely short, almost 

 continuous with the tibia, apparently two-jointed ; the terminal joint being scarcely visible under a lens. 



The splendid purple gloss on the upper side of the large wings of the type of this genus, the regularly oval form, and the ocellated 



under surface of the hind wings, the somewhat concave apical margin of the fore wings, and the very slightly scalloped margins of all 



the wings, are the most evident distinctions of this genus. I have, however, only examined a single male, not in the best condition, but 



which is, I believe, unique, in Dr. Boisduval's collection. It is a native of the East Indies. On the under side the basal half of the
