68 DESCRIPTIVE CATALOGUE. 



the wings are white with a blueish cast ; they have, on both pairs, along the posterior margins, 

 two parallel brown striga, of which the interior is undulated, enclosing an interrupted series 

 of oblong brown spots, gradually assuming a deeper tint as they appi'oach the anal angle : 

 interior of this follows a macular band, originating by two successive ocellate dots, from the 

 margin of the fore wings and extending in an irregular curve through both pair : the disk of 

 the fore wings bears a short curved streak, and a similar angular mark, but more obscure, stands 

 on the hinder wings : the latter are further marked, in their basal portion, with numerous black 

 ocellate spots bordered with white, of which five are more prominent; two of these stand near 

 the exterior margin, the apical one being larger and of a more florid tint ; two, less conspicuous, 

 are disposed near the anal interior margin, and a fifth intermediate not far from the base. An- 

 tenncB annulated with white. Tufts of grayish blue hairs at the sides of the thorax and abdomen. 



This species is abundant. About twenty specimens are contained in the collection. It appears to be the 

 representative of the Lyccena Arion, in the eastern tropical regions. Among Indian species which have 

 recently been added to our systematic catalogues, it most nearly resembles the Pol, Duponchellii, from Timor, 

 described by MM. Latreille and Godart in the Encyclopedie : but it differs by the deep azure tint diffused over 

 its upper surface, and by the number and arrangement of the ocellated spots underneath. It forms a 

 natural transition, by its marks and habit to the next following genus.
