 Wings above, va. the male, cyaneous blue, with a saturated silvery reflexion changing according to 

 the light to sea-green, the borders throughout and the exterior dimidial portion of the fore 

 wings, defined by a boundary extending obliquely across the disk, being black, the inner exca- 

 vated margin of the hinder wings gray; in the female sordid white, all the wings with pale azure 

 silvery irrorations confined to the base, fore wings with broad brown borders, hinder pair 

 faintly clouded with brown and paler anterior margin, bearing two rows of minute black spots 

 parallel with the posterior margin and an extreme black thread ; the two interior spots of the 

 exterior series being larger more pronounced and succeeded by an obsolete brown lunule 

 on the anal appendage ; fringe throughout gray : underneath satin-gray with a common striga of 

 minute black arcs, beyond the middle, regular and disposed in close contact in the fore wings 

 flexuose and farther removed from the margin in the hinder pair, interrupted by a more con- 

 spicuous arc or angular mark in the curve at the anal region, opposed to the medial space 

 between the tails ; the fore wings have besides between the principal striga and the margin a 

 regular series of very obsolete oblong grayish spots faintly margined with white ; this is continued 

 in the hinder wings by a double series of the same kind with more distinct spots and fol- 

 lowed in the anal region by two intensely black ocellate spots, the exterior one near the marginal 

 notch being small regularly circular and bedded in a large fulvous patch with an abruptly 

 transverse interior edge, the other ocellus occupying the anal appendage, being oblong-trans- 

 verse, bordered internally by a fulvous lunule and ornamented externally by a narrow metallic 

 streak ; between these is a round group of delicate silvery irrorations on a hoary ground. The 

 tails are black with white edges and tips ; the antenna brown with a ferruginous tip, and marked 

 on one side with delicate transverse grayish dots. The body is covered with a bluish sea-green 

 down above and with delicate white hairs underneath. 



Amblypodia Longinus deviates both in the larva and imago states from the species described in the third 

 section, which I consider as typical in this subgenus. The larva is considerably distended anteriorly, 

 excavated at the sides, contracted behind and transversely swelled at the segments (see Plate iv. fig. 5). 

 In the imago state the peculiarity chiefly exhibits itself in the antennae, which are abruptly terminated by 

 a short point (see Plate iv. fig. 5, a). In the character of the anal appendages and of the tails, the various 

 species arranged in this section generally agree, with the exception of Amblypodia Etolus ; but nothing is 

 as yet known of their metamorphosis ; and the investigation of the larva forms of this subgenus, which is so 

 much diversified in the imago state, deserves the closest attention of Entomologists in foreign countries. 



Amblypodia Longinus is not unfrequent, and I obtained six male and five female specimens chiefly by 

 breeding: the larva feeds on a species of Loranthus, which grows parasitically in great abundance on the 

 Mango and other fruit trees surrounding the villages of the natives. The discoidal litura, represented in 

 the figures, does not appear in all our specimens.
