or abdominal margin, marked out by the obtuse-angled apex, the tail, and the well-rounded 

 anal angle ; with a black, oval, sexual mark, divided by the submedian nervure, near the 

 anal angle ; costal nervure short and straight, terminating before, and the first branch of the 

 subcostal which originates close to the base of its nervure ending beyond, the middle of the 

 length of the costal margin, the second branch being given off before the middle of the 

 discoidal cell, and extending into the apical angle ; the discoidal ncfvule in the same straight 

 or slightly curved line with the subcostal; the disco-cellular nervule sinuous ; the third Dudian 

 nervule produced to a conspicuous tail. Antmnce fine and distinctly clubbed. Female 

 unknown." {Wood- Mason, 1. c, in Journ. A. S. B.)

Habitat : Trevandrum, Travancore. 

 Expanse: 2*4 inches. 



DESCRirTiON : "Male : Upperside, both wings dark fuscous, suffused with rich deep 

 violet. Foreiving with an outwardly and forvvardly arched, subcrescentic, pale violet or 

 mauve band, commencing beyond the middle of the wing at the costal nervure, terminat- 

 in"- at the inner angle, and crossed obliquely by a series of three small white spots 

 disposed in a straight line parallel to the outer margin, and placed upon folds of as 

 many consecutive interspaces, the last being between the second and third median nervules. 

 Hindwin° relatively longer tailed than in Melanitis isinene, Cramer, with the membranous 

 parts of the divergent tail almost wholly formed by the produced wing-membrane of 

 the interspace between the second and third median nervules, a very narrow anterior 

 membranous edging only being contributed by the interspace next in front ; and with 

 rather more than the basal two-thirds of its length in front of the discoidal nervule and sub- 

 costal nervure ochreous. Underside, both wings ochreous, obscurely striated with a deeper 

 shade of the same colour, and marked with a submarginal series of inconspicuous brown 

 specks, the probable rudiments of ocelli. The female will, in all probability, prove to 

 differ from the male not only in the absence of the sexual spot in the hindwing, but also in 

 having the inner margin of the forewing straight, and neither lobed at the base nor turned 

 up in the middle, and the first median nervule and the submedian nervure normally arranged and 

 developed, and directed respectively to the outer margin and to the inner angle after the 

 manner usual among butterflies." {Wood-Mason, 1. c, in Journ. A. S. B.) 



P. marshalli has as yet only been found in Travancore, where it was discovered by 

 Mr. H. S. Fergusson on the Ashamboo Hills in May. 



The figure shews the upper and undersides of a male specimen from Trevandrum, South 

 India, in the Indian Museum, Calcutta.
