922 REVISION OF AUSTRALIAN LEPIDOPTERA, 



Wimmera, Victoria ; several specimens (Coll. Lucas). Nearest 

 to T. Shepherdi ; in my tabulation it falls under the same heading 

 with T. gratiosa, from which it is immediately separated by the 

 entire fascia of hindwings. 



^O'- 



SOROCOSTIA, ROS. 



Tribunia scabralis, Walk. Suppl. 1507, appears to be a species 

 of this genus, but is certainly not in a condition to be identified, 

 and the name should be neglected. 



Sor. higuttalis, Walk. 



( Tribunta biguttalis, Walk. Suppl. 1507; Sorocostia trigonota, 

 Meyr., Proc. Linn. Soc. N.S.W. 1886, 719.) 



Identified from the original specimen. 



Sor. hesycha, n. sp. 



(J^. 15-17 mm. Head and thorax white, thinly sprinkled with 

 grey. Palpi 3, white, irrorated with grey on lower half. An- 

 tennae, abdomen, and legs white. Forewings elongate-triangular, 

 costa hardly arched, apex round-pointed, hindmargin slightly 

 rounded, oblique ; white, densely irrorated with ochreous-grey ; 

 a narrow clear white streak from | of costa to disc before middle, 

 anteriorly margined with dai'ker irroration ; a similar streak from 

 costa before apex to inner margin beyond middle, hardly curved 

 inwards ; an indistinct parallel whitish streak near hindmargin 

 on lower half : cilia white, irrorated with ochreous-srrev. Hind- 

 wings and cilia white, apex sometimes greyish-tinged. 



Geraldton and Carnarvon, West Australia ; in October and 

 November, four specimens, mostly taken at light. Nearest to 

 S. irenica ; in my tabulation it falls under the same heading Avith 

 S. parallacta, from which it is at once distinguished by the white 

 hindwings, and clear white lines of forewings.
