Eastern Pierulce. 99 



Taclujiis ega, Boisduval (p. 371). 



Mr. Wallace proposes (p. 316) to drop the Fabrician 

 name melania altogether, as being a species "which has 

 not yet been properly identified, and probably never Tvill 

 be'-* (p. 371). The original specimen of the melania of 

 Fabricius is in the Banksian cabinet, and agrees with 

 Donovan^s figure, which was evidently made from it. The 

 anterior wing has its base of rich orange ; the posterior 

 wing is altogether pale, with a band of darker browm a 

 little below the middle, followed by some indistinct white 

 spots. It seems to be distinct from melania, Boisduval. 



Tachyris Jacquinotii, Lucas (p. 372) . 



I believe this has no relationship ^vith zoe, Vollenhoven, 

 or agave, Felder, or vriili the group to which they belong; 

 and if I can trust my memory, and a note made several 

 years ago, Jacquinotii is the same as Pieris isandra of 

 Boisduval, a South-American species. Lucas says that it 

 comes from Xew Guinea. He may be in error, I may be 

 more so. 



Tachyris nephele, Hewitson (p. 380) . 



This should come next to aria (p. 367) ; Mr. Watson 

 tells me it has the same plumules. It is probably another 

 variety of hjncida and hippo. 



Prioneris thestylis, Doubleday (p. 384). 

 Prioneris seta, Moore (p. 384) . 



P. seta,MT. Wallace says, is "a very puzzling species." 

 But it seems to me that he has himself created the difii- 

 culty by describing as the male of seta an insect which 

 belongs to a different species, and by assigning to that 

 male (after the fashion of some of his oriental species of 

 Papilio) two females which are totally different. P. seta 

 of Moore is the female of thestylis of Doubleday ; and the 

 insect which Mr. Wallace describes as the male of seta is 

 a closely-allied species with a female which scarcely differs 

 from the male. I propose to call this species Prioneris 

 Watsonii, as a recognition of the good work which my 

 friend Mr. Watson has done and is doing to elucidate our 

 favourite study. I should have done this a year ago, 

 when I sent a note upon this group of butterflies to the
