BY E. MEYRICK, B.A. 691 



with a blackish apical spot, costal cilia white. Hindwings thinly 

 scaled, in male whitish-grey, in female pale grey ; cilia in male 

 white, in female whitish, with a faint darker line near base. 



Distinguished from all by the broad uninterrupted white costal 

 streak from base to apex, and light grey groundcolour. 



Abundant amongst Leptospermum scrub, generally in sandy 

 places, round Sydney and at Parramatta, from August to 

 December. 



11. Streps, sicariana n. sp. 



$ . 7". Head white, with one or two grey scales. Palpi 

 elongate, not tufted, white mixed with grey beneath, terminal 

 joint dark grey. Antennae grey, in male slightly thickened, and 

 notched at about one-tenth from basal joint. Thorax white. 

 Abdomen light silvery-grey, anal tuft whitish. Legs whitish, 

 anterior and middle tibia? and tarsi suffusedly banded with 

 dark fuscous-grey. Forewings moderately narrow, costa gently 

 arched, hindmargin slightly sinuate beneath apex, very oblique ; 

 dark fuscous-grey, dorsal half suffusedly white sprinkled with 

 grey ; a sharply-defined fusiform white streak along costa from 

 before middle to apex, acutely attenuated at each extremity, 

 suffusedly margined beneath with blackish, costal edge with 

 slender oblique brownish-grey strigulse, of which two or three 

 towards apex cross the white streak ; an oblique blackish mark 

 above submedian fold before middle ; cilia white, extremities of 

 hindmarginal cilia mixed with grey, with a black apical spot, 

 and a dark grey smaller spot a little below it. Hindwings thinly 

 scaled, grey ; cilia whitish, with a faint grey line near base. 



Allied to S. obeliscana, but very distinct from that species 

 through its larger size, dark colour, and the white costal streak 

 extending only from before middle to apex. 



One specimen taken in dry scrub near Sydney in February.
