York, West Australia ; three specimens bred in December. 

 The larva feeds on Hakea (an unidentified species with leaves 

 metamorphosed into stout spines), making long contorted tubes 

 of silk covered with refuse amonst the twigs, in October.

Male 31mm. Head and thorax grey. Palpi grey-whitish, irro- 

 rated with dark-grey. Antenna? grey-whitish. Abdomen ochreous- 

 grey-whitish. Legs dark fuscous irrorated with whitish, posterior 

 tibia? w^iitish. Forewings elongate, moderate, costa gently arched, 

 slightly sinuate beyond middle, apex obtuse, hindmargin obliquely

Geraldton, West Australia ; one specimen bred, which emerged 

 some months after my return to England. Larva 16-legged, 

 cylindrical, w-ith short, scattered, blackish hairs ; grey, irregularly 

 tinged with reddish and greenish, becoming dull greenish beneath; 

 spots small, whitish ; head dark brown, marbled with whitish-

 to 4 inches long, oblong-linear, margins serrate, apex emarginate), 

 amongst the spun-together leaves of terminal shoots, in October. 

 This larval habit, reminding one of the To7'tricina, is quite excep- 

 tional in the genus. The species is closely similar to the follow- 

 ing, but differs in shape of wing and neuration, as well as in 

 details of marking.
