"While Bates, Felder, Kirby (1871) and Standinger, deceived b}' the iiatterii 

 cil the iusect, put P. hyppason in the Ariarathes Group, Haase placed it with 

 P. pharnaces and anchisiades. That is indeed the correct position, as is borne out 

 by the structure of the imago. In the new edition of Hilbner the species is placed 

 by Kirby in Ithobalus, the type of which is an Aristolochia-Swallowtail. The 

 insect has many peculiarities sejjarating it from the other members of the 

 Anchisiades Group. It is individually rather variable, but does not appear to have 

 split up into geographical forms. The sj)ecies can easily be recognised by the 

 presence of a large red spot ou the imderside of the hindwing behind cell close 

 to base. Kirby, I.e., makes the erroneous statement that the marginal spots of the 

 hindwing of P. ki/ppason are red. 



(J ¥ . Antennae in male a little extending beyond apex of cell of forewiiig, in 

 female not reaching apex of cell ; club gradual and long, end-segment conical, 

 basally broader than in the allied species. Palpus black. Spots of breast grey 

 or buff, those on pronotum rufous red. Scales of upperside of forewing obtusely 

 ((?) or more acutely (?) tridentate, the white ones partly bide ntate, those of the 

 upper layer of the last patch in male entire ; on underside the scales strongly 

 bidentate, those of the upper layer entire from the middle of the hindmargiu 

 forward, especially the white ones. The spots of tbe hindwing consist of rufous red 

 and white scales ; the red scales narrow, long, entire or feebly sinuate, opalescent, 

 many being yellow at base ; some of the dark scales at the edge of these spots or 

 within them bright metallic blue under the lens. 



Nenration : M' and M- of forewing closer together tha\i R-' and M' ; PC of 

 hindwing evenly curved, SC- more proximal than in the allied species, standing 

 closer to base than to R'. 



Genitalia : <?. Tenth tergite spatulate, beneath carinate, except at apex ; tenth 

 sternite laterally with two teeth projecting upwards, the second tooth pointed, 

 the first mucli shorter, hairy ; clasper short, broad, rounded ; harpe broad, the 

 ventral margin raised and distally produced into a tapering process ; beyond this 

 process the har])e narrowed to a slightly spatulate lobe, which is curved vcntrad 



and bears a variable number of teeth at the rounded apical edge. ? Edge of 



vaginal aperture raised, denticulate laterally, bisinuate in front, the mesial frontal 

 lobe triangular ; in front of the orifice a high ridge, strongly chitinised ; between
