18 (b). Deudorix epijarbas armstrongi, ssp. n. 



This is the Tongan representative of D. epijarbas, and is closely allied to 

 D. epijarbas doris, from which the female (PI. I, fig. 8) differs as follows : 

 the pale area of the forewing (diffuse, small and sometimes almost absent in 

 both D. epijarbas doris and diorella) is a clearly-defined triangular patch, filling 

 the base of interspace 2 and nearly the whole of the basal two-thirds of inter- 

 space 1, and extending also into interspace la. The form resembles D. epijarbas 

 diorella in the possession of the orange lunules on the inner side of the anal lobe 

 on the upperside, and in interspace 2 of the hindwing on the underside. The 

 black spot in interspace 2 of the hindwing is slightly developed on the upperside 

 in all three females of D. epijarbas armstrongi but not in any of the females of 

 D. epijarbas doris or D. epijarbas diorella that I have seen. Type and two 

 paratypes (48, 42, and 38 mm. in expanse) from Neiafu, Vavau, Tonga, 7.iii.26 

 (J. S. Armstrong). Male and early stages unknown. 



Armstrong found this subspecies not uncommon on the shore at Neiafu 

 on Morinda citrifolia, and states that it was not feeding on the flowers but 

 settling on the leaves ; most were out of reach, and he was only able to capture the 

 three females mentioned. I met with both sexes rather sparingly at Nukualofa on 

 Lantana and at Neiafu, but all my specimens were destroyed on the journey home.

Although this form varies considerably, more particularly in the width of 

 the terminal black band on the upperside of the forewing in the male, it can 

 readily be distinguished from Jamides carissima (described by Butler from a 

 specimen from Erromango Island, New Hebrides) by the greater width of this
