This and the three following species are very closely allied 

 together; they belong to the group of scalar iella,7i. and gemoniella 

 Stt. They are best distinguished from one another by the 

 different groundcolours, and the colouring of the inner-marginal 

 streak and of the head ; ochrocephala is also to be known by the 

 slender white streak along costal edge. Two specimens, from 

 mixed growth at Sydney and on the Bulli Pass, in October and 

 November. 



Grrac. nereis, n. sp. 



$ . 4". Head and thorax glossy- white tinged with brassy- 

 yellow, lateral margins of thorax blackish. Maxillary palpi white, 

 exteriorly dark fuscous. Labial palpi white, second joint 

 exteriorly dark fuscous, terminal joint with some scattered 

 fuscous scales. Antenna? longer than fore-wings, dark fuscous. 

 Abdomen blackish above, wholly snow-white beneath. Legs 

 white, tarsal joints with broad dark fuscous rings at base, anterior 

 tibiae dark fuscous, middle tibiae hardly thickened, dark fuscous 

 with white median band, posterior tibiae stiff-haired. Fore-wings 

 dark fuscous, with a rather broad brassy yellowish-white stripe 

 along inner-margin from base .terminating abruptedly at anal 

 angle, very strongly black margined above ; a white circular spot 

 on hind-margin just above anal angle ; a thick black oblique 

 streak from costa at four-fifths, extending to the white hind- 

 marginal spot ; a similar streak just before apex, ending in apex ; 

 cilia dark fuscous-grey, with two white posteriorly black margined 

 strigulae above apex, and a black apical hook. Hind-wings 

 blackish-fuscous, cilia slightly paler. 



Nearest to didymella; distinguished by the darker ground 

 colour, brassy-metallic tints, and the obscuration of the while 

 costal streaks with black scales. One specimen on a fence in 

 Sydney, in November.
