2g2 RHOl'ALOCERA MALAYANA. 



Male. Wings above dark violaceous-blue, the fringe brownish. Wings beneath ochraceous-brown. 

 Anterior wings with two looped spots, margined with pale bluish in cell and a subquadrate spot, inwardly 

 mart^ined with pale bluish and outwardly with greyish at end of cell, a waved fascia margined with 

 greyish crossing wing beyond cell, and the following spots margined with greyish :— one near costa 

 above end of cell, and two beneath cell divided by the lower median nervule ; the apical third of wing 

 is somewhat paler, and contains a marginal and submarginal dark fascia. Posterior wings with the 

 following spots and fascia; margined with greyish : — seven basal spots, a central transverse fascia, which is 

 connected above at the lower subcostal nervule with a broken macular fascia extending to abdominal 

 margin ; a marginal and two submarginal somewhat obscure fascia ; three transverse marginal metallic 

 gi-eenish spots near anal angle. Body and legs more or less concolorous with wings. 



Female. Wings above violaceous-blue, costal and outer margins of anterior wings broadly fuscous ; 

 posterior wings with the costal margin broadly, and the outer margin narrowly, fuscous. Wings beneath 



as in male. 



Exp. wings, 3 , 50 to 58 millim. ; ?, 52 to 58 uiillim.

This is the true I'apilio centaunis, Fabr., of which I have satisfied myself by a comparisou 

 witli the Fabrician type coutained iu the Bauksian collection in the British Museum. 

 Considerable confusion exists as to the true identity of this species, and this has been greatly 

 due and is still frequently caused by the erroneous representations of the species given by the 

 late Mr. Hewitson,* which seem to apply to a variety or distinct species found in Continental 

 India. It is probably these figures which have induced many to consider as distinct the Malay 

 butterfly described by Felder under the name of Amblijpodia nakida. Mr. Kirby, iu his Catalogue,! 

 placed the two species as synonymous with one another ; and, to render the matter as 

 complicated as possible, N. M. Kheil has recently pointed out that Mr. Kirby is wrong, and 

 uses Felder's name as distinct from the Fabrician. Mr. Butler, in 1869, 1 corrected this 

 error, but his remarks appear to have been overlooked. 



This is an abundant Lycasnid in the Malay Peninsula, and its distribution extends through 

 Tenasserim into Burma, but, owing to the confusion as to identity, its known geographical area 

 is somewhat difficult to ascertain.

Female. Wings above violaceous-blue; costal and outer margins of both wings broadly fuscous. 

 Wings beneath pale brownish, with the following spots and fasciae margined with greyish :— anterior wings 

 with two spots in cell and one at end of cell, two spots beneath cell divided by the lower median nervule, 

 a somewhat curved macular fascia between end of cell and outer margin commencing near costa and 

 terminating at lower median nervule, and a more obscure submarginal fascia ; posterior wings with about 

 seven basal spots, a subquadrate spot at end of cell continued as a macular fascia to abdominal margin, an 

 outer discal macular fascia which becomes duplex near anal angle, and a somewhat obscure submarginal
