Jfings above brown, in the Tnale more saturated and covered with a very rich cyaneous blue lustre 

 which disappears almost entirely in a certain direction to the light ; a narrow border in both 

 wings and a large discoidal spot in the anterior pair always preserve the original ground colour 

 inclining to blackish ; in the female the tint is without blue lustre and slightly clouded with 

 grayish brown, a saturated brown band passes a little behind the disk through both pair, being 

 flexuose in the hinder and accompanied in the anal region by a subdimidial arched band con- 

 sisting of a series of confluent broad white spots ; behind this a Very faint narrow band passes in 

 a curve across the whole wing, and close to the margin is a somewhat more distinct row of spots 

 originating at a small distance from the outer apical angle enclosed by two delicate white strigae 

 being continued in the anal region by two very large deep black ocelli, encircled by white rings, 

 while a fainter ferruginous spot covers the anal appendage ; the latter also appears in tlie male 

 and a brilliant white marginal thread winds in both sexes along the anal region, exterior to which 

 is a black marginal thread while the wings are uniformly terminated by a grayish fringe : under- 

 neath the wings are silvery-gray with a faint glaucous cast ; on the disk of each pair stands a short 

 double reddish-yellow litura ; behind this follows a more distinct and saturated common band of 

 the same colour, narrowly edged on both sides with brilliant snow-white lines, nearly straight with 

 an oblique outward tendency in the fore wings but slightly interrupted and flexuose in the hinder 

 wings ; then an angular mark resembling the letter V standing at the curve in the anal region, 

 from which a detached line passes obliquely to the inner margin, having a fainter line parallel 

 to it at the extreme boundary ; between this band and the extreme margin passes a connected 

 series of obsolete brown marks which is complete in the fore wings and subdimidial in the 

 hinder pair, being followed in the anal region by two veiy large black circular ocelli separated 

 by an intermediate oblong group of white dots, which are crowded more distinct and brilliant 

 in an attenuated transverse streak adjoining the interior ocellus ; the latter occupies the anal 

 appendage itself and is bordered internally by a narrow white arc while the exterior ocellus is 

 surrounded by a very large orange lunule ; posteriorly both ocelli are bordered by a brilliant 

 white waving marginal line exterior to which is a black thread and gray fringe. Body brown 

 above, hoary underneath : abdomen marked laterally with white bands. Antenna brown with a 

 ferruginous tip, and delicate white bands along the filiform basal portion. Eyes covered with a 

 delicate ferruginous down and edged posteriorly with white. Legs covered with a white down 

 and marked with black bands. 



This species occurred occasionally in my breeding-cages ; as the larva was not delineated I conclude that 

 it is nearly allied in form and appearance to the other larva of this genus. Our specimens are one male 

 and two females. The authors of the Encyclopedie have given the first description of this species.
