Plate I, fig. 6 ; 6, a. 



Wings above, in the male, bright azure with a snowy refulgence spread as a delicate white powder 

 over the surface, while the ground colour assumes in a different aspect a pale sea-green cast ; 

 the fore wings are ornamented with a delicate white silky brush-like appendage, reflected and 

 closely applied to a blackish spot on the middle of the disk ; the margins are black, gradually 

 increasing in breadth to the tip, being separated by a curved boundary from the azure ground ; 

 in the hinder wings the posterior border is marked with a black thread extending to the anal 

 appendage, which bears besides a black lunule ; the extreme fringe is gray ; in the exterior 

 margin is a hemispherical denudated silvery spot, corresponding with a delicate brush of 

 lengthened hairs in the under side of the fore wings ; the interior border is covered with a delicate 

 whitish down, slightly fringed with gray : underneath the wings are grayish brown with a very 

 faint livid lustre; a strongly pronounced broad snow-white band passes in a straight line through 

 the middle of both pair to the anal region of the hinder wings, where it becomes narrower, 

 and after several minute curves, stretches obliquely to the interior margin ; between this and the 

 hinder margin is a very delicate blackish thread composed of small linear fragments, in close 

 contact, arranged in a regular curve across the fore wings, slightly interrupted and curved in 

 the hinder, forming in the anal region a delicate edge along the medial white band ; the hinder 

 wings are further marked within the posterior margin with a row of oblong spots of the ground 

 colour enclosed within a double series of white lunules, and continued in the anal region by 

 two very large circular black ocellate spots, the exterior one being surmounted by a large 

 oblong patch of a bright orange tint abruptly terminated at its contact with the black striga, the 

 interior one occupying the anal appendage, being covered internally with a white arc sending off 

 a short oblique line along the inner margin; the space between the ocelli is gray, irregularlv 

 irrorated with black and marked in the middle by an indistinct white lunule, a brilliant white 

 thread passes along the entire anal region, exterior to which is a continued black marginal 

 thread, and finally a grayish fringe. Body with a varying bluish or sea-green tint above, 

 covered with a yellowish down underneath ; antenna: brown, with a closely catenulated lateral 

 white line extending to the origin of the club, the tip of which is ferruginous; tails black with 

 a white tip and grayish fringe. 



This species, as appears from a drawing in the possession of General Hardwicke, is also found on the 

 continent of India. In Java it is comparatively rare, a single male specimen was brought to England.
