Collection Number 56,56 a. Four male and six female specimens, 

 Arisan, 7300 feet ; Daitôzan, 8500 feet ; Jujimichi, 5000 feet ; August 

 and September, 1908. 



A recent trip to Arisan in the month of August of 1908 enabled 

 me to capture a long series of var. daitoaana, numbering in 

 all some thirty specimens. The female was described by me in a 

 previous paper from two worn females and I now give for convenience 

 of reference à description of both sexes. The wings are white in both 

 sexes as in var. albida. 



Alale, var daitoaana, differs from var. albida, Leech, as follows : — 

 Only two greyish spots show on upperside, forewing, one at 

 apex of discoidal cell, the other in first median interspace, these 

 are merely transparent from below and are not dark blue as in 

 albida, J. Albida, J, has seven spots on the upperside, forewing, 

 which are dark blue and judging from Leech's figure trans- 

 parent from below. On the underside there is no large black spot 

 in centre of the cell as in albida and the sixth spot of the central 

 discal band of forewing, which is present in albida, is absent in male 

 daitôaana. This band is also more regularly curved in daitoaana from 

 costa to first median interspace than it is in albida. Hindwing, upper 

 and lower side as in albida, only the central band is straightcr than 

 in albida. 



Female, var. daitoaana. Has three spots on upperside, forewing, 

 the third being in second median interspace and generally only a 

 dot ; these spots are not transparent from below but are reproduced in 

 black ; a broad black submarginal border to hindwing with submarginal
