of wing at three-fourths : cilia fuscous. Hindwings blackish- 

 fuscous, ferruginous-tinged ; a small suffused orange discal spot ; 

 a very broad deep orange hindmarginal band, not reaching costa, 

 suffused at anal angle, including a submarginal series of small 

 subconfiuent blackish-fuscous spots, becoming larger on lower 

 half ; a blackish-fuscous hindmarginal line : cilia fuscous. 



Geraldton, West Australia ; in November, five specimens. This 

 and the two following species are nearly together, but certainly 

 distinct ; S. heliopis may be recognised by the narrower trans- 

 verse discal spot of the forewings, the fuscous cilia, larger discal 

 spot of hindwings, and very broad orange band, with a series of 

 well-defined dark spots in both sexes. 



Syn. austera, n. sp. 



Male and female, 40 mm. Head, thorax, and abdomen whitish- 

 fuscous. Palpi snow-white. Antennae dark fuscous, ringed with 

 white. Legs whitish-ochreous. Forewings elongate-triangular, 

 hindmargin strongly rounded, rather oblique ; pale fuscous, 

 ochreous-tinged ; veins partially marked with blackish-fuscous 

 lines, an irroration of grey-whitish scales forming a band beneath 

 middle from base to two-thirds, thence curved upwards to costa at 

 four-fifths, and also a narrower band along hindmargin, partially 

 confluent w"ith preceding above middle ; a triangular white 

 median discal spot ; a faintly marked ochreous-whitish suftusion 

 preceding the subterminal band on upper half of wing, divided 

 into spots by dark veins : cilia whitish-ochreous, with one or two 

 fuscous lines, tips whitish. Hindwings dark fuscous ; in female 

 a sufiused orange discal dot ; an orange fascia extending from 

 middle of wing to apex, somewhat dilated upwards ; in female a 

 suffused submarginal series of cloudy orange spots before upper 

 two-thirds of hindmargin ; cilia whitish, basal third fuscous. 



Carnarvon, West Australia ; in October, two fine specimens 

 taken together in a damp place on the plain. Easily distinguished 

 from the preceding and following by its larger size, lighter colour- 

 ing, the triangular discal spot of the forewings, and the less ex- 

 tended orange colouring of the hindwings. 



Syx. brontias, n. sp. 



Male and female, 25-33 mm. Head, thorax, and abdomen 

 fuscous. Palpi snow-white. Antennae dark fuscous, ringed with
