the male, by a series of smaller spots, parallel with the hind 

 or outer margin, and sometimes continued on to the hind-wing. 

 Three females from Tahiti in the British Museum were also 

 male-like, but a fourth exhibited a slight development of a 

 brownish shade on the margins of both wings. 



The five females sent by Mr. Simmonds from Rarotonga 

 showed great variation. Their chief differences were described 

 below, omitting the central marking of the hind-wing which 

 was treated separately at the end. 



(1) This specimen was male-like and, except for its much 

 greater size, nearly resembled the Tahitian female. 



(2) Smaller — the only one of the five which, in this respect, 

 did not contrast with the Tahitian specimen, — darker, the 

 white fore-wing bar overspread with scattered dark scales, 

 the series of white spots parallel with the hind margin slightly 

 developed, as also the orange ochreous marginal and sub- 

 marginal lines in both wings, tending to invade the apical 

 area of fore-wing. 



(3) In this specimen the series of white spots, present on 

 both wings, was more developed, as also the orange ochreous 

 markings, especially at the apex of fore-wing. 



(4) Similar, except for the still greater development and 

 richer shade of the orange ochreous and the slightly less 

 developed series of white spots. 



(5) The white fore-wing bar overspread as in (2) ; the 

 ochreous markings very pale, nearly white in the apical area. 

 In the hind-wing the pale ochreous submarginal marking 

 was no longer a line but a band much broader than in any 

 other of these five females. The President, however, had 

 captured specimens in Rarotonga with a far greater develop- 

 ment of ochreous, recalling some of the Fiji females of 

 bolina. 



The relation of the central blue markings of the male hind- 

 wing to that of the various forms of female was of much 

 interest and strikingly illustrated by the specimens exhibited 

 to the meeting. 



The male patch was made up of blue scales, some of which 

 becoming pink when seen at certain angles, combined with the 

 blue to form a lilac shade. This marking usually had an
