Heterocera from the Australian Region. 415 



indicated by a diffused greyish streak ; a slender abbreviated 

 oblique whitish anal stripe, well separated from the greyish patch 

 on external border ; the latter suffused with lilacine. Expanse of 

 wings, 46 nim.

EEMIGIID^E. 



KEMIGIA, Guenee. 

 56. Remigia discrepans, n. s. 



$ , Closely allied to _R. archesia and R. mayeri ; differing in 

 the ochraceous clay-colour of the primaries, the costal border and 

 basal area alone being slightly suffused with lilacine-grey ; in the 

 absence of markings across the centre of these wings, and in the 

 inner line being replaced by a slightly inarched abbreviated black- 

 brown transverse stripe with whitish internal edge ; secondaries 

 almost exactly as in R. archesia ; on the under surface it differs 

 from the latter in its sandy yellow instead of reddish ochreous 

 colour, in the reduction of the markings on the primaries, and the 

 almost total obliteration of those on the secondaries. Expanse of 

 wings, 42 mm. 



Viti Islands. 



But for the well-defined blackish bar at the basal third 

 of the primaries I should have thought it possible that 

 this might be the female of R. mayeri. 



THEBMESmXE. 



EEOSIA, Guenee. 



57. Erosia stolida, n. s. 



Allied to E. theclata of Africa and Ceylon (female of Dirades 

 binotata) ; differs from both sexes of that species in its superior 

 size, considerably paler, silvery greyish coloration ; the markings 

 white-edged, but not enclosed by an outer brown line ; the outer 

 margin of the primaries in the female more irregular than in 

 E. theclata. Expanse of wings, 22 23 mm.

The genus Erosia has hitherto been placed among the 

 Geometrites, but it has been shown that its true position 

 is amongst the Pseudo-Deltoids ; the genus Dirades has 

 hitherto been regarded as distinct, but it is now evident 

 that it is founded upon the males of certain species of 

 Erosia, the sexes of which differ in outline of wings.
