charina. The uncus (fig. 14) is abruptly curved at its 

 distal end. It bears some resemblance in outline to the 

 upper mandible of the beak of a gull. The scent-scale 

 (fig. 11) is like that of charina, but generally longer. 



(3) P. liliana, Grose Smith. — This is a well-marked 

 subspecies from Mombasa and the adjacent region, in- 

 cluding Taveta and Machakos. It is on the average con- 

 siderably larger than any of the other forms of the charina 

 group. The wet-season male is veined with black on the 

 upper surface, and is somewhat heavily marked with grey 

 on the inner half of the costa of the fore-wing and the base 

 of both wings. The apex and posterior margin of the fore- 

 wing are margined with black. There are no discocellular 

 spots on either wing. The wet-season female may be either 

 white or yellow on the upper surface ; it has a broad dark

border to the fore-wing, with which the costal part of a 

 submarginal chain is usually merged. The hind- wing is 

 bordered by a series of large dark sjjots, sometimes fused 

 together. The submarginal spot between the second and 

 third median branches is very large and conspicuous; and 

 there is always visible a spot, belonging to the same series, 

 in the space between the median and submedian, usually 

 passing the boundary of the latter vein. A submarginal 

 band or row of spots is sometimes visible on the hind-wing. 

 A discocellular spot is always present on the fore-wing, 

 and usually on the hind-wing also. Beneath, the wet- 

 season male is white with small dark marginal dots and a 

 chain of submarginal brownish spots, more or less developed, 

 on both fore- and hind-wings. Discocellular spots are present 

 on both wings, and there is a large and conspicuous 

 submarginal spot between the second and third median
