80 Transactions. — Zoology, 



second line white, tolerably well-defined, obscurely dark-margined ; sub- 

 terminal very ill-defined, cloudy, whitish, interrupted above middle, not 

 touching second line : cilia ochreous-whitish, obscurely barred with grey, 

 and with two grey lines. Hindwings 1J, light grey, darker posteriorly ; 

 cilia whitish, with a well-defined grey line. 



Compared with the neighbouring species a rather large and dull-coloured 

 insect, with the lines more abruptly bent and angular than usual. 



Wirrabara Forest, South Australia, in October ; five specimens. 

 * 12. Scop, perierga, n. sp. 



Male, female. — 14-15 mm. Head, palpi, and thorax white, densely 

 mixed with fuscous and black ; palpi 3. Antennae dark fuscous ; ciliations f . 

 Abdomen dark grey, segmental margins white. Legs white, irrorated with 

 dark fuscous ; tibias and tarsi clear white, sharply banded with black. 

 Forewings triangular, costa slightly arched, apex rounded, hindmargin

 fuscous or yellowish-fuscous, and irregularly irrorated with black ; a short 

 thick interrupted cloudy blackish streak from base of costa; first line in-

 margined posteriorly on costa and inner margin by triangular black spots ; 

 orbicular small, dot-like, blackish ; claviform moderate, round, wholly black, 

 detached ; reniform x-shaped, blackish, upper fork generally filled obscurely 

 with whitish, lower with ochreous, and connected with costa by a cloudy 

 dark spot ; second line tolerably distinct, white, anteriorly dark-margined ; 

 terminal space wholly dark, except moderate cloudy white subterminal 

 line, interrupted above middle, apex of lower portion almost touching 

 second line : cilia white, mixed and obscurely barred with grey, lower half 

 spotted with dark fuscous. Hindwings 1J, whitish-grey suffused with 

 darker, apex and upper part of hindmargin suffused with dark fuscous, 

 central lunule and postmedian line tolerably distinct ; cilia grey- whitish, 

 with a broad grey basal line. 



A comparatively short-winged species, allied to S. eremitis, but much 

 smaller and more distinctly marked, the dark markings much blacker. 



Mount Wellington, Tasmania, from 3,000 to 3,800 feet, in December ; 

 rather common, sitting on the rocks and readily disturbed. 

 * 13. Scop, gomphota, n. sp. 



Male. — 15 mm. Head, palpi, and thorax grey, mixed with reddish- 

 ochreous and black ; palpi 2J. Antennae grey ; ciliations h. Abdomen 

 grey. Legs white, tibiae and tarsi banded with dark grey. Forewings tri- 

 angular, costa hardly arched, apex rounded, hindmargin straight, rather 

 strongly oblique ; fuscous-grey, with a few black and bluish-white scales ; 

 a small reddish-ochreous spot near base ; first line not paler, curved,
