the upper and over the whole surface of the hind wings ; dis- 

 coidal spot on uppers dusky black. Antennae orange-tipped. 



Expanse 1^ inch ; wings more elongate than in P. nina. 



Hab.—Menado, Celebes (Coll. Wall.). 



A very distinct species, with more elongate wings than its 

 allies. 



Elodina, Felder. 



Voy. Novara, Lep. p. 215. 

 This is a group of small delicate white and black butterflies, 

 which have a peculiar type of neuration, there being only one 

 subcostal nervule before the end of the cell, and the lower radial 

 is situated so high up as to appear like a branch of the subcostal 

 at the end of the cell. The type has been considered a Terms, 

 and others have been placed in the genus P'leris. They seem 

 allied to both Ponlia and Teiias, and are the only well marked 

 group of Pieridce which are entirely confined to the Australian 

 region. The species yet known are all very closely allied to each 

 other. 



1 . Elodina egnatia, Godart. 



Pier'is egnatia, Godt. Enc. Metli. ix. p. 138. Terias egnatia, 



Bd. Sp. Gen. p. 678. 

 Hab. — N. Celebes (Wall.) ; Amboina (Bd.) ; Aru Islands 

 (Wall.); Timor (Wall.) 



The Timor specimen is smaller and has the dusky mark beneath 

 the uppers reduced to a subquadrate spot, but I do not like to 

 separate it. 



2. Elodina lujpatia, Felder. 

 Elodina Jujpatia, Feld. Voy. Novara, p. 216. 



Hab.—^ew Guinea (Coll. Wall.). 



Distinguished by the upper wings having beneath a black apex 

 enclosing a white stripe ; but in some specimens these markings 

 are almost or quite obsolete, and they then only differ by the costa 

 above being more broadly dusky at the base. 



3. Elodina therasia, Felder. 

 Elodina therasia, Feld. Voy. Novara, p. 215. 



Hab.— G\\o\o. 



" Above, like E. egnatia ; beneath, has the apex beyond the 

 dark patch dusky." I have not seen this species.
