additional .sjiot in front of tlie second discoidal nervule, and always another mark at 

 the anal angle, which i,s seldom indicated above in the other sex. In one of mv 

 males the tail is rather thin, and scarcely narrowed towards the base ; the spot at the 

 apex of the tail is very feebly marked aliove in this specimen. Between the subcostal 

 and the upper discoidal nervules there stands sometimes a white subniarginal sjjot 

 on the imderside of the hindwings in the male; in the female this spot is alwavs 

 present below, and in some individuals also above. 



The scent-organ of the male is creamy white.

In the Felder collection there is one male of this species labelled .Mus»oree ; the 

 locality label of this specimen belongs most probably to that individual of P. ravaim 

 .Moore in the Feld. coll. which bears the label " Daijeeling, Stoliczkn," while the 

 latter label belongs to the " Mussoree " e.xample of latreMei

In the shape of the hindwings this insect comes close to P. lalreillei Don.: in 

 the position of the submarginal spots of the hindwings it agrees with latreillei Don. 

 and alcinous Klug. The short and feebly spatulate tails bear, as in lalreillei, a 

 red spot; the scent-organ of the male is white, as in that species; but there are 

 no discal white markings to the hindwings. The thickened hinder tiliiae are not 

 peculiar to P. crassipes Oberth. ; we find them in pkiloxenus Gray, and especially 

 in alcinous Klug, alcinous menciiLS Feld., polydm-us L., and se\eral other species, 

 though in crassipes the hind tibiae seem to be rather thicker than in any other 

 Papilio.

Smaller and darker than P. latreillei Don. ; the hindwings are sliorti-r and tlieir 

 outer margin more scalloped ; the tails are without a red spot ; the ba.sil half of the 

 hindwings is broader than in latreillei; the di.-cal white spots are mostly reddish 

 wlute ; they vary in number from three to five ; the anterior one standing before the 

 second discoidal nervule is often joined to the corresponding submarginal mark. The 

 female is much paler above than the iiiale, as is generally the case in the species of 

 this group.

P. adamsoni bears a striking resemblance to P. aristolochiae Fabr. As both 

 species belong to the nauseous Papilios, the similarity in [latteni cainiot be accounted 

 for by mimicry : we have here certainly a beautiful case of parallel de\elopment.
