XXXIX. .MACAKEUS-GEOUP. 



The species of this group are all mimetic. Some of" them resemble otlier 

 mimetic Papilios of the clytin-grouY>, but can at once be distinguished by the first 

 subcostal nervule of the forewings being anastomosed to the costal nervure. Males 

 with a more or less developed abdominal fold to the hindwings as in the preceding 

 groups XXX. to XXXVIII. 



A. Discoidiil cell of the hindwings very long and narrow; first discocellular 

 nervule originating at about the basal sixth of the subcostal vein. 



Note. — Scales of the white markings on the upperside of the wings (except the 

 costal region of the liindwings) narrow ; in macareiis, stratocles, deucalion, leuc(ulion, 

 thule, the scales are hair-like ; in the Indian mefjarus they are somewhat broader 

 and are emarginate at the apex ; in niegaribs Jlexiniacula Eothsch. they are still 

 broader, bidentate, and in megaera Standing, almost normal, but narrower than the 

 brown scales. — K. .T. 



a. Abdomen with four white lines, two on each side; middle line of the under 

 surface black. Males with the abdominal margin of the hindwings (wlien the fold 

 is expanded) provided with long hairs for its whole length, with a woolly scent-organ 

 along this mai-gin.

Five local forms are known to me : — 



(«) : 1'. nutciireus Godart from Java ; 



(b) : I'. macKreus indicua m. from XorUi India and Hurma ; Tenasserim ; 



Malacca (?) ; 

 (c) : P. nuicareii.s xanthosoma Standing, from Sumatra ; 

 (d) : P. macareus macaristus Grose Smith from Borneo ; 

 (e) : P. macarens niaccabcteits Standing, from Palawan. 



(") : P. macareus Godart, forma typ. [<?,?]. 

 .Mr. II. Kruhstorfer obtained the typical form of P. macareus Godart both in 

 West and Kast .lava ; I have only two West Javan specimens before me, which are 

 remarkabh' different from the Indian insect that most authors treat as macareus 

 Godart. The hinder angle of the forewings of typical macareus is more rounded 

 than in the Indian race, the postcellular white streaks are broader, the last but one 

 is not or scarcely divided into two, the black line inside it being very thin or only 

 exteriorly marked ; the three short streaks of the discal row between the upper 

 median and lower subcostal veins are not notched exteriorly. The first white streak 

 on the hindwings is much narrower ard shorter than in indiciM ; below, the costal 

 emargin is not white. Tiie white lines of (lie abdomen are much narrower; the 

 vntral black middle Hue much broader
