whitish bands of the fore wings ; but the characters on 

 which I should rely for its distinction are the absence of 

 the subcostal black dot near base, the single apical hair- 

 pencil of the abdomen in male, and the possession of 

 only one or two black scales in place of the decided 

 spot of T. centetes. It agrees with T. centetes, and 

 differs from any of the other Australian species in the 

 presence of vein 10 of the fore wings, and of the black 

 dot on the base of first segment. 



Trichoptilus xerodes, Meyr. 

 Also from York, West Australia. 



Tetraschalis, n. g. 



Forehead without tuft. Auteunas minutely ciliated (\). Palpi 

 moderately long, ascending, with appressed scales, terminal joint 

 long, filiform. Tibiae tufted with scales on origin of spurs. Fore 

 wings bifid, cleft from middle; veins 2 and 4 stalked, 3 absent, 

 5 and 6 very short, 7 froni below angle of cell, long, 9, 10, and 11 

 out of 8. Hind wings trifid, third segment with tuft of black 

 scales in dorsal cilia ; vein 2 from middle of cell, 3 absent, 5 and 6 

 very short, 7 to apex. 



Allied to Oxyptilus, but distinguished by having vein 

 11 of the fore wings rising out of the stalk of 8, 9, 

 and 10. 



Tetraschalis arachnodes, n. s. 

 cf, 21 — 24 mm. Head, palpi, thorax, and abdomen light 

 brownish-ocbreous, mixed with whitish, reddish, and dark fuscous

 tudinally striped. Fore wings with segments linear, first slightly, 

 second posteriorly moderately dilated, pointed ; reddish-fuscous, 

 sprinkled with whitish and irrorated with dark fuscous ; a cloudy 

 narrow white baud on base of first segment, a broader one at its 

 middle, and a narrow one at three-fourths, two latter also indicated 

 on second segment ; cilia grey, irregularly mixed throughout with 

 black scales. Hind wings cleft firstly from one-fourth, secondly 

 from near base, segments linear; fuscous, third segment dark 

 reddish-fuscous ; cilia grey, third segment with a few black scales 

 on upper margin, on lower margin with a tolerably continuous row 

 of close black scales from near base to apex and a fringe of white
