discal interspaces more or less brown, bnt interspace between median bars SC° — R^ 



of forewing and cell of the same light colour as the discal interspaces. Forewing: 



median bar R' — M' midway between most proximal point of discal bar R' — M' and 



base of M' or closer to the latter. Hindwing : discal Inniform bars C — R' evenly 



arched, not almost angle-shaped ; discal interspaces C — R' twice as wide as the 

 respective median interspaces ; two tails, upper one spatulate, 7 to 9 mm. long, 

 second curved costad, 6 to 7 mm. long. 



Length of forewing : S, 34 — 39 mm. 

 „ „ ?, 42— 48 mm. 



Penis with a lateral patch of teeth as in marmax; penis-funnel, however, as 

 broad as in aristogifon. 



Hub. Philippine Islands, apparently on all the islands of the group. 



The race from Mindanao is so different, especially in the ¥ , from those found 

 on Mindoro and Luzon, that we should have treated it as specifically distinct, if we 

 had not a 7nale specimen from Mindanao which resembles the Mindoro individuals 

 more than the extreme Mindanao examples. Besides, caroltis, amycua and georgius 

 are clearly geographical representatives of one another ; we must, therefore, expect 

 that iutergradatious also between the females will be found when more material 

 from all the islands of the Philippine group has come to hand. 



Drs. Staudinger and Butler made a mistake in identifying the Mindanao insect 

 with the form described by Felder, which came from Luzon. This erroneous 

 identification misled Dr. Staudinger to describe the Mindoro form, which is very 

 slightly difl'erent from that inhabiting Luzon, as a distinct species. Dr. Butler, in 

 his revision of the genns r^«;r/ic('«, brings the Mindoro race^fo;y?'«« in the '■^ psaphon 

 group," while the Mindanao race stands under the name of amycus in the " marmax 

 group." 



Gh. amycus connects the allies of Ch. marmax with those of Ch. polyxena.

S. Wings above rich tawny orange. Forewing : median bars R- — M'- ves- 

 tigial, the last often absent, or bars R-— M' black, but short and thin and not curved, 

 median bars SO' — R- often tawny ; discal bars R=— SM- thin, often tawny brown, 



sometimes not arched, the last one often very faint. Hindwing : postdisco-sub- 



marginal patches R' — R' very much smaller than patches C — R\ but in one example 

 as in the following subspecies. 



Underside : median bars R^ — M' of both wings continuous, or R= — R' a little 

 more proximal ; postdiscal interspace SC" — R' of hindwing about as wide as 

 respective discal interspaces ; tails very variable in length, upper one 2 to 4 mm., 

 second 1| to 3| mm. 



? . Wings abore orange ochraceous, discal area of forewing somewhat paler. 



Forewing : median bars feeble, often vestigial only, sometimes absent ; discal bars 

 often all tawny, postdiscal interspaces of the same colour as disc, s])ot SC^ — SC well 

 marked ; bar D sometimes vestigial only ; veins within black postdisco-marginal 

 area with orange ochraceous scaling. Hindwing : postdisco-submarginal patches
