PAPILIONINJE. 109 



Imago. — Male. Forewing slightly elongated, triangular ; costa arched, apex 

 obtuse, exterior margin oblique and slightly concave in the middle, uneven, posterior 

 margin short ; first subcostal branch anastomosed to the costal vein. Hindwing 

 short, triangular ; exterior margin somewhat convex, scalloped ; abdominal margin 

 very hairy beneath, folded over above, the fold when opened displaying a lengthened 

 scent-organ, consisting of a dense sei-ies of fine long silky-hairs, extending from the 

 base along middle of the marginal interspace. 



Larva and Pupa. — Unknown. 



Type.— P. Macareus (W. M. and de N.). 



Mimicry. — The species of this genus are mimetic, some resemble species of the 

 Limnaine genera Parantica, Badena, and Ideopsis, also of the Nymphaline genera 

 Hestina and Parhesiina, and certain females much resemble the same sex of the 

 Euploeine genus Trepsichrois ; others those of the mimetic Papilionines of the genera 

 Cadiigoides and Chilasa. 



Dimorphism. — This is known to occur in the female of certain species — namely, 

 in that sex oC Paranticopsis indicus, of which we describe and figure both forms, 

 Pruhstorfer, in Berl. Ent. Zeit. 1902, pp. 222-3, also figures a female of his Pai). 

 indochinensis and of Pap. argentiferus, which are doubtless dimorphic forms. The 

 Paj). Astina, "Westwood (figured in " Cabinet of Orient. Entom." pi. 9) is also, 

 probably, the dimorphic form of the female of the Java species, P. macareus, Godt., 

 the normal form of female of this latter species being that figured in Horsefield's 

 plate 5 * — of which specimen we possess a coloured drawing made by the same 

 artist.

Imago. — Male. Upperside black; cilia very slenderly alternated with white. 

 Forewing with a small white basal-costal spot, and a few minute clusters of white 

 scales faintly visible along the costal edge ; with three greyish-white outwardly- 

 oblique broad cell-streaks and also two short streaks within its apex, four spots 



* Horsefield's Java Collection was transferred from the East India Company to the British Museum in 

 1860, but the specimen of this female of Alacareus is not in the British Museum Cabinet, and we have 

 failed to discover what has become of it. This female is enumerated, with two males, in the E. I. C. 

 Museum Catalogue of Lep. vol. i. p. 90, published in 1857, as being at that time in the Collection.
