'Orange, "upp&r half oi wing dark fuscous; the fuscoug color ex- 

 tends as a thick streak along termen towards anal angle ; cilia 

 fuscous, around anal angle yellowish. 



Betweenl aiiricejjs, Butl., chrysanthes. Turn., differing from 

 both by orange hindwings. A similar peculiarity is notice- 

 able in Western Australian Cctsyra crocinastis, Meyr. 



Port Victor, South Australia; one specimen received from 

 .Messrs. S. and F. Angel, taken in March. 



Atheropla scioxantha, n. sp. 



Male, 15 mm. Head orange-yellow. Palpi ochreous, 

 second joint beneath fuscous. Thorax, antennae, and abdomen 

 dark fuscous, antennae annulated with ochreous-white, anal tuft 

 • ochreous. Forewings elongate, moderate, costa gently arched, 

 termen obliquely rounded ; pale yellow ; markings fuscous ; a 

 moderate, thick streak along costa from base to middle, some- 

 times continued to apex ; a well-marked spot on lower edge 

 of streak at one-third ; a short suffused streak from base along 

 inner margin, curved up so as to almost touch last^mentioned 

 spot; a moderate spot at posterior extremity of cell, beneath 

 which is a fuscous suffusion extending to anal angle, and there 

 meeting a thick fuscous shade along termen ; cilia yellow, with 

 2 or 3 fuscous teeth at base, becoming wholly fuscous at anal 

 angle. Hindwings pale ochreous ; cilia dark fuscous. 



Differs from the other species by the dark thorax, yellow 

 hindwings, and cilia. 



Stawell and Birchip, Victoria ; two specimens, in November. 



MIMOBRACHYOMA, n. g. 



Head smooth, antennae thickened, dentate, very shortly 

 criiiated (|), basal joint moderate, without pecten, or with one 

 or two hair scales. Palpi smooth, moderate, second joint 

 hardly reaching base of antennae, terminal joint shorter than 

 second, recurved. Thorax smooth. Abdomen rather dilated. 

 Posterior tibiae clothed with long fine hairs above. Forewings 

 with vein 7 to apex, 2 and 3 stalked, from angle. Hindwings 

 with 3 and 4 from a point, almost stalked in one specimen, 

 cilia one-third. 



Allied to Sphyrtlata. Meyr., differing principally by the 

 stalking of veins 2 and 3 of forewings. The genus is formed 

 for the reception of eusema. Lower (Proc. Linn. Soc, N.S.W., 

 p. 413, 1900); an insect much resembling Sphyrelata (?) ochru- 

 phosa, Meyr. Mr. Meyrick, in describing that species, sur- 

 mised that probably a new genus would be required to receive 

 it, and should eusema prove to be a geographical form of orhro-
