300 Lloyd's natural history. 



having red markings towards the anal angle of the hind-wings 

 beneath. 



The fore-wings are much produced and rather narrow, the 

 hind-margin being very oblique, and slightly concave ; the 

 hind-wings are ample, rounded, and scalloped. There are 

 always large red (or more rarely, yellow) spots at the base of 

 the wings beneath, and in the females, at the base of the fore- 

 wings above. 



The male is black, thickly dusted with blue on the nervures 

 towards the hind-margins ; on the under side of the hind- 

 wings there is a sub-marginal row of large round black spots 

 bordered inside with red lunules, and a large red blotch enclos- 

 ing two or three black spots towards the anal angle. The 

 female has brown fore-wings, with the nervures broadly 

 bordered with grey, and a large red spot in the cell at the base ; 

 the hind-wings are black at the base, to the end of the cell, 

 with the disc white ; there is a row of sub-marginal black spots, 

 outside which, and towards the anal angle, the white is strongly 

 stained with yellow. The under side of the wings is marked 

 with large red spots at the base, as in the male, and the anal 

 angle is stained with yellow instead of red. 



The cluster of forms which Dr. Wallace places together under 

 the name of Fafilio meninon have no red spots at the anal 

 angle, though Wallace figures a female from Java hardly dif- 

 fering from typical /. agenor. The females generally have 

 the greater part of the hind-wings white on the upper side, 

 and some of the forms are furnished in addition with long 

 spatulate tails. /. inemnon (Cramer) is the type of the genus, 

 but when its true female has been accurately determined, it 

 will have to take its name (most of these doubtful forms 

 having been figured under different names by Cramer and 

 others) ; for the description and locality assigned by Linnceus 

 to his Pd/'ilio mcmnon^ as well as Petiver's figure, which he
