586 REVISION OP AUSTRALIAN LEPIDOPTERA, 



shallowly emarginate so as to form a short obtuse triangular 

 projection on vein 6 and a broader one on vein 3 ; pale greyish- 

 ochreous, becoming rosy-whitish towards costa, with a few scat- 

 tered dark grey strigulee ', costa narrowly deep ochreous-yellow, 

 with a few black dots ; lines cloudy, dark grey, starting from 

 strong oblique black costal strigulse ; first angulated on apex of 

 strigula ; second dentate, between costal strigula and middle 

 curved outwards but nearly obsolete, on lower § followed by a 

 reddish-fuscous blotch nearly reaching hindmargin ; an interrup- 

 ted blackish hindmarginal line : cilia white, with a sharp fuscous 

 line internally edged with ferruginous, externally forming spots 

 on projections. Hindwings with hindmargin waved, angulated 

 on vein 3 ; light reddish-fuscous, more greyish towards middle of 

 hindmargin, and becoming pale greyish-ochreous towards base, 

 with some scattered dark grey strigulee ; second line straight, 

 somewhat irregular, cloudy, dark grey ; hindmarginal line and 

 cilia as in forewings. 



Mount Lofty, South Australia, in March ; one specimen (Coll. 

 Guest). A neatly marked and singular species. 



2. Diastictis, Hb. 



Face with projecting tuft of scales (sometimes slight). Tongue 

 developed. Palpi moderate, porrected, rough-scaled, terminal 

 joint moderate, loosely scaled. Antennae in <J bipectinated with 

 short stout pectinations, apex simple. Thorax not crested, slightly 

 hairy beneath. Femora glabrous ; posterior tibiae in <J somewhat 

 dilated, often bent. Forewings in <J with well-marked fovea 

 (rarely slight); vein 10 absent, 11 anastomosing or connected 

 with 12 and 9, or free. Hindwings normal. 



A nearly cosmopolitan genus of some considerable extent, 

 forming a development of Selidosema, and closely connected with 

 it, though the extreme forms differ much. In many exotic species, 

 which cannot be generically separated, the antennae are simple, 

 and transitional forms occur. The absence of vein 10 of the 

 forewings, which occurs only in some species of Selidosema, is 

 here invariable. The Australian species are only stragglers.
