RHOPALOCEIIA MA LA VAX A. yr.a 



This appears to be a moderately scarct; species, and is related to some very closely allied 

 forms in the neighbouring islands. Were the butterflies of the whole Malayan region being 

 described, it would be possible to pursue the more reasonable course of arranging these local 

 though distinct forms under one specific grouping, but, as the Rhopalocera of the Malay 

 Peninsula are here alone enumerated, that course cannot be followed. 



16. Papilio caunus, var. aegialus. (Tab. XXVII. //, tig. 5 J .)

Male. Wings above dark indigo-blue. Anterior wings with the following greyish-white spots: — 

 a large spot crossing cell just before its extremity, preceded l)y a subcostal streak and followed beneath by 

 two spots separated by the upper median nervule and a submarginal row of small spots which are more 

 or less tinged with bluish ; a small bluish discal spot between the second and third median nervules. 

 Posterior wings with the cell, and adjoining streaks between the nervules, — practically absent between the 

 upper discoidal and first median nervules, and longest and largest between the lower median nervule and 

 submedian nervure, — greyish white ; these streaks are outwardly notched and margined with pale liiuish : 

 a submarginal series of small lunulate whitish spots. Wings beneath dark brownish, with the greyish- 

 white markings as above, the submarginal spots tinged with bluish. Body dark indigo-blue, spotted — 

 especially beneath — with greyish; legs dark indigo-blue. 



Exp. wings, (? , 90 to 94 millim. 



Hab. — Malay Peninsula ; Sungei Ujong (Durnford — coll. Dist.) ; Singapore (coll. Godfery). 



The interest attaching to this local race of E. caumis is principally owing to its beiug 

 a "mimic" of Euplcea diocktianus, whicli is also the local race or form in the Malay Peninsula 

 of E. rliadamauthus.* We thus see this mimicking Papilio modified in the same manner as 

 its mimicked Eupkea, and if E. diocletiainis is to be recognised as a distinct species, this local 

 form, variety, or race, will have (in an artificial and systematic sense only) to be recorded 

 in the same way. I have been recently informed by Mr. 0. Salvin that he has received 

 Bornean examples of the Papilio which mimic the Bornean form of the Euplica, viz. E. loivei.
