BUTTERFLIES OF SAMOA AND SOME NEIGHBOURING ISLAND-GROUPS. 53 



Pupa very pale brown, with a considerable amount of dark brown freckling 

 on the dorsal surface. The imago hatches after eight days.

A series collected in Tonga by Armstrong and myself differs considerably 

 from the specimens in the British Museum, owing to the more leaden ground- 

 colour of the males ; but Captain N. D. Riley, who has kindly examined them 

 for me, informs me that in his opinion they are all J. carissima, and that the 

 colour of some of them has possibly been altered by damp. This is confirmed 

 by the fact that the metallic scales seem to lie much natter and more evenly 

 in the older specimens, than in those collected by us. The blue colour in the 

 two females of the latter is somewhat more restricted than in the older ones ; 

 this may perhaps be seasonal, but the numbers are quite insufficient to prove 

 anything. In size, the two series do not appear to differ ; the maximum, 

 mean, and minimum expanse of my ten males are 30, 26, and 23 mm., while 

 two females measure 27 and 25 mm. respectively. All seem somewhat smaller 

 than specimens from the type-locality (the New Hebrides), and in all probability 

 a new racial name will be required for them when more material is available. 



The early stages are unknown, but the food-plant is probably a 

 Leguminous creeper with rather large pink flowers, round which the butterflies 

 were usually seen. 



Rather common at sea-level in Vavau, Haapai, and Togatabu at the time 

 of my visit ; Armstrong also found it common in March 1926. Schmeltz's 

 record of L. argentina from Niuafou probably refers to this species ; with the 

 exception of Danaida archippus, it appears to be the only butterfly yet recorded 

 from this exceedingly isolated outlier of the Tongan group.

There is in the British Museum a single male of this species from the 

 Godman-Salvin collection, labelled Tonga (67. F. Mathew). As pointed out by
