spot in a red ring. The presence of this red and black eye- 

 spot at the anal angle on the upper side sufficiently distin- 

 guishes this group from any other black and green East Indian 

 Butterflies. The larva is green, with the thoracic segments 

 somewhat thickened behind, and two short whitish horns on 

 the first and last segments ; segment seven has a whitish trans- 

 verse band, dotted with reddish, and surmounted by two 

 small white horns; the fourth, fifth, and ninth have similar 

 transverse bands; the belly is white, varied with red. The 

 pupa is grey, much arched, with a bifid head, a long spine on 

 the pectus, and the lateral ridges of the abdomen strongly 

 serrated beneath. The larva feeds on a species of Fagara 

 called " Sampang " in Java. 



[LX. A.] This genus includes a number of East Indian 

 Butterflies of moderate size, to which some authors have 

 improperly proposed to restrict the generic name Laertias, 

 Hiibner. One of the commonest species is Papilio polytes, 

 Linn. The sexes are very dissimilar. The male, which 

 Linnaeus called Papilio pammon, has broad and rather short 

 fore-wings, the hind-margin being oblique to the level of the 

 hind-wings, which are ample, dentated, and furnished with a 

 spatulate tail. The wings are black, the fore-wings with a row 

 of white marginal spots, and the hind-wings with a t'ansverse 

 and slightly curved white band, divided into spots by the 

 nervures ; sometimes the anal angle is marked with orange 

 above, but always on the under side, where there is also a sub- 

 marginal row of orange lunules. The female (the true P. 

 polytes, Linn.), instead of the white band on the hind-wings, 

 has a large white spot in the middle of the latter, below which 

 is a red spot at the anal angle and a row of rather large red 

 sub-marginal spots. The nervures of the fore-wings are bordered 

 with white on the disc. There is a second form of the female 

 (Papilio romulus^ Cramer), with extensive red markings on the
