RHOPALOCERA MALAYAN A. 235 



three slender tail-like appendages situate respectively at tlu^ apices of the second and third median 

 nervules and of the submedian nervure. Costal nurvure extending to about apex of wing, the subcostal 

 nervules bifurcating about one-third before the end of cell ; first and second median nervules emitted close 

 together near end of cell. Palpi moderately long, much compressed, second joint projecting more than 

 half beyond the head and longly hirsute beneath ; apical joint slender, but well formed ; antennse with a 

 gradually formed but well-developed apical club. 



Only one species of this genus is at present described, and as it is here enumerated 

 the specific habitats must be taken as representing our present knowledge of the generic 

 area of distribution.

Male. Wings above dark violet-blue, with the costal and outer margins somewhat narrowly dark 

 fuscous ; posterior wings with an inner greyish marginal line from beneath the subcostal nervules and 

 with three transverse greyish submarginal streaks near anal angle divided by the median nervules, 

 tail-like appendages fuscous, with their apices greyish-white; fringe of both wings greyish. "Wings 

 beneath greyish-brown. Anterior wings with three rufous spots, margined with black and silvery crossing 

 cell, a series of silvery spots in the subcostal area, two beyond cell divided by the lower discoidal 

 nervule, two or three beneath cell (both of these followed by ocbraceous and black), an outer and irregular 

 discal series of five spots crossing wing and a submarginal series in which the silvery hue is somewhat less 

 intense ; between the discal and submarginal series of spots are some dark fuscous markings. Posterior 

 wings with the following rufous spots, margined with black and silvery :— two beneath costal nervure, one 

 (round) about centre of cell, and one (transverse) at end of cell, two beneath cell and situate between the 

 submedian nervure and third median nervule, and one (transverse) about centre of abdominal margin ; on 

 about basal third of costal margin are some rufous, black, and silvery markings, two discal series of silvery 

 spots margined with black cross wing, between and beyond which are some black spots on a rufous ground 

 colour, a sul>margiual series of pale silvery spots placed between the nervules, that between the second 

 and third median nervules replaced by a black spot margined with rufous, and the silvery spots at anal 

 angle margined with black; tail-like appendages pale fuscous with their apices greyish-white; fringe of 

 both wings silvery grey. Body above and beneath more or less concolorous with wings. 



Female.— Wings above pale violet-ljlue, with the costal and outer margins broadly dark fuscous, 

 the posterior wings with three pale transverse spots near anal angle divided by the second and third 

 median nervules and the inner margin also narrowly silvery at this area. Wings beneath with the ground 

 colour much paler than in male, but with the markings similar. 



Exp. wings, 3 and 2 , 27 to 35 millim. 



Hab.— Ceylon (Thwaites— coll. Dist.).— Malay Peninsula; Perak (coll. Godfery) ; Sungei Ujong 

 (Durnford— coll. Dist.).— Borneo (Lowe— coll. Godm. & Salv.). 



Since this beautiful insect was described from a Bornean specimen, it has been found 

 to inhabit both the Malay Peninsula and Ceylon, and has doubtless an even wider geographical 

 distribution. Chromo-lithography has proved unequal to producing the silvery metallic
