assemblage is no doubt based on the " Revision "; * and 

 we have already seen that three of its members, viz. 

 ornytion, ladas and dohertyi belong not to Huphina but to 

 Delias. There remains persephone, Staud., from Waigiou. 

 This form, as Fruhstorfer says, " was formerly only known 

 in one defective male specimen, and described as Delias.'''' 

 His figure, which appears in loc. cit., PI. 63 d, as Huphina 

 odyssia, is indistinguishable from specimens of ornytion 

 from the Arfak Mountains in N.W. and from Kapaur in 

 W. New Guinea, on the underside of which forms the sub- 

 marginal red line of the hind-wing is wanting, and the 

 yellowish patch on the apex of the fore-wing may also be 

 absent, as in the figure of "odyssia." Staudinger f was 

 no doubt right in placing persephone in the genus Delias: 

 there was also some justification for his surmise that a 

 larger number of specimens, perhaps from other localities, 

 might show that persephone is a local form of ornytion. 

 As we have seen, there is no assignable difference between 

 the Waigiou form and specimens of D. ornytion from 

 Western New Guinea. Staudinger speaks of ornytion 

 as from S.W. New Guinea, but Godman and Salvin's 

 specimens, including the type, were taken near Port 

 Moresby. Even in these the submarginal red line was 

 almost obsolete; in another specimen from Port Moresby 

 it is entirely lacking, as in the type of persephone. 



We may sum up as follows : — 



Abnormis is not a Tachyris (as Wallace, and Grose Smith 

 and Kirby in their plate) ; nor a Delias (as Grose Smith and 

 Kirby in their text and indices, also Hon rath) ; nor a 

 " Pier is (Appias)" (as Staudinger); but a Huphina (as 

 vmi Mitis,J Butler and Fruhstorfer). 



Euryxantha (not euryxanihe) is not a Delias (as Honrath 

 in his description and (irose Smith and Kirby in their 

 plate §) ; nor a Tachyris (as the two latter authors in their 

 text and indices) ; nor a " Pirn's (Appias) " (as Staudinger) ; 

 but a Huphina (as von Mitis. Duller and Fruhstorfer). 

 It may probably be conspecific with abnormis. 



* The reference to Oberthiir's Etudes, "p. (il " (instead of p. (i), 

 above noted in the " Revision," is repeated in Fruhstorfer's Alpha- 

 betical List of [ndo-Australian Pierines; loc. cit, p. 185.
