pnnded below, and are dcntated and sub-caudalc, or furniblicd 

 with a strong tooth at the outer angle ; the inner half of the 

 wing is brown at the base, and dirty white beyond. On the 

 under side of the hind-wings is a large red blotch at the 

 outer angle, with some black spots in the middle and on the 

 hind-margin ; and there are several more red spots towards 

 the margins above the large patch. In the female, the white 

 inner marginal space is absent, and the red markings of the 

 under surface are at least faintly visible above, but frequently 

 there are two rows of sub-marginal pink spots. This very 

 curious Butterfly is still scarce in collections. 



[lxvil] The type of this still un-named genus is Papilio nox, 

 Swainson. This, and the few allied species, are peculiar to the 

 Malay peninsula and the adjacent islands of Borneo and Suma- 

 tra, and are remarkable for their dark colour, very long fore- 

 wings, rounded at the tips, and long narrow rounded hind- 

 wings. 



[lxix., pt.] Pccnasniia, Moore. We now come to two pecu- 

 liarly-shaped genera which are restricted to North India. 

 Fcenasniia dasarada (Moore) is the type of one genus. It ex- 

 pands 5^/2 inches across the wings; the fore-wings are long, 

 narrow, and rounded at the tips, and the hind-wings are very 

 long and narrow, forming three large lobes on the hind-margin, 

 and then expanding into a very broad tail, slightly constricted 

 at the base ; within this are two more lobes, one at the inner- 

 margin, and one between this and the tail. The fore-wings are 

 dark grey, with the nervurcs, intermediate lines, and a series of 

 longitudinal lines in the cell, black ; there are several large 

 square white spots on the hind-wings, which are scarcely marked 

 with red on the upper side ; but on the under side the three 

 on the hind-margin are white, that on the tail is red, and the 

 three at the anal angle and on each side of it are red, more or 

 less marked with white on the inner side.
