LEPIDOPTERA. 



93 



Wings above blackish brown, with a violet reflexion in the male, which is of a deeper shade towards 

 the base, the anterior bearing a large irregularly rounded rufous orange spot on the medial 

 areola, the hinder being marked with a posterior border of the same colour ; in the male the 

 medial spot is smaller, consisting of a transverse cloud, and in the posterior pair the border is 

 narrowed and undulated at the inner edge, being composed of confluent lunules; a narrow undu- 

 lated black streak passes along the posterior margin ; the fringe is white interrupted with black 

 at the nervures, and in the fore wings evanescent towards the outer apical angle; the female has 

 besides a short transverse black stigma before the disk of the fore wings, and in the hinder pair, 

 near the middle, a faint orange dash : underneath the wings are bright sulphureous yellow; both 

 pair have a sanguineous posterior border, which in the anterior wings is narrow and uniform, until 

 it approaches the inner apical angle, where it is terminated by a short black streak edged on 

 both sides with white ; in the posterior wings it is broader and ornamented internally by a series 

 of white arcs delicately edged on both sides with black; a series of small wedge-shaped black 

 spots, bedded in an oblong sub-marginal cloud of white irrorations, is arranged parallel with the 

 black marginal thread, which is confined by the extreme fringe ; a minute black dot stands 

 between the disk and base, and two more obscure ones are distantly arranged alono- the inner 

 margin ; the fore wings have besides a very faint series of brown lituras, and the hinder pair of 

 interrupted white streaks parallel with the post-marginal border ; the anal appendage is termi- 

 nated by a black spot and the tails have a white tip. The body is brown above and hoary under- 

 neath; the legs are alternately white and black; the antennce are black with delicate white bands 

 to the commencement of the club. 



This species is not unfrequent in the acclivities near the confines of the extensive medial plain of Java. 



Our museum contains eleven specimens, of which several are males. It was named and described by 

 Messrs. Latreille and Godart in the Encyclopedic, but the figure has not previously been given. The 

 anterior feet, of both sexes, have been carefully examined under the microscope, and confirm the details 

 given in the generic description.
