9 . Wings above lighter and dingier, much in fact, as in P. cliaon, 

 Wesfcw., -with the fascia of the underside of the anterior ones faintly 

 indicated. 



Anterior wings below with an incurved ashy-white fascia beyond the 

 end of the cell, commencing near the costal margin, interrupted by the 

 veins and folds, and rapidly decreasing to the third median veinlet, where 

 it ends to recommence at the first, whence it increases to the submedian 

 vein. 



Tails of the posterior win^s broader at the expanded extremity and 

 narrower at the constricted portion, just as in P. cliaon Q. as compared with 

 its males. 



Length of anterior wing 2 - 35; whence expanse = 4*86 inches. 



Seven males and two females. 



Family HESPEKIM]. 



lOi. Ismene chromus, Cramer. 



Andaman females all have only a single small semitransparent subapical 

 speck between the last two branches of the subcostal of the anterior wing ; 

 but those from Continental India have sometimes one and sometimes two 

 besides this on the disk of the same wing, which in one from Bangalore 

 in South India are enlarged into two conspicuous reversed comma-shaped 

 spots. 



105. Ismene malayana, Felder. 



The females have a small semitransparent yellowish discal speck be- 

 tween the two posterior branches of the median vein and of course lack the 

 oblique band of short lines of modified scales seen in the males of this as 

 well as of the preceding closely-allied species. 



106. Ismene aria, Moore. 



107. Ismene lebadea, var. andamanica, nov. 



'$ . Wings above dark brown of a slightly greenish tinge, all without 

 spots. 



Anterior wings bearing a huge and dense pear-shaped sericeous patch 

 of setse glossed with greyish -greenish and extending nearly from the bottom 

 of the angle formed at the base of the organ by the subcostal and submedian 

 veins about to the level of the end of the fourth fifth of the length of the 

 latter vein, with all the setae directed backwards and slightly outwards ; 

 with the costal margin purplish ; the outer portion beyond the setulose 

 patch bronzy ; and the cilia pale luteous.
