BUTTERFLIES OF SAMOA AND SOME NEIGHBOURING ISLAND-GROUPS. 49 



The species is common in Tonga in the neighbourhood of Neiafu, where 

 both Armstrong and I saw it in plenty ; Schmeltz records it from Liku 

 in Togatabu. On my second visit to Vavau, a fortnight after the first, I did 

 not see a single specimen, so that it appears to have sharply- defined seasons 

 and to fly only for a very short period. It is apparently a very rare insect in 

 Samoa, or possibly only very local. The only certain record I have is that 

 of the female described above, but Brass thought he saw two or three others in 

 the same district in November 1925 ; unfortunately he was not able to capture 

 any of them. It is possible that the species is seasonally common in Tutuila, but 

 we failed to find it on any of our visits, and it is not mentioned in Swezey's list. 



Schmeltz says of the larva : " Resembles, according to Dr. Graeffe, that 

 of our Cabbage White ; is brown, with yellow tubercles on which stand a few 

 hairs, and lives on Cucuebitaceae." He does not say with which race he was 

 dealing, but it appears to have been the Tongan one.

Rather common in the Nukualofa district, Tonga ; I did not take it else- 

 where, but there are in the British Museum collection two specimens from the 

 Vavau group, taken by the Eclipse expedition in April or May 1911. Schmeltz 

 recorded the form as occurring in Samoa as well as in Tonga and Fiji, and his 

 record is repeated (with a query) by Rebel ; the record has, however, never 

 been confirmed, and it is very doubtful whether the specimen came from Samoa. 

 Certainly no form of T. hecabe occurs in Upolu now, and we did not see it or 

 obtain records of it from any other part of Samoa. 



Variation in this form appears confined to the black marginal border of the 

 upperside of the hindwing, which is almost obsolete in some specimens (including 

 the type), but quite well-developed in others. 



18 (a). Deudorix epijarbas doris, ssp. n. 

 Closely allied to D. epijarbas diorella Waterh., of Fiji, from which it differs 



as follows : Male. — Upperside, fiery-red colour on forewings (almost confined
