Daaringa, Rosewood, and Brisbane, Queensland, from Septem- 

 ber to December; eight specimens, and type seen. Whilst super- 

 ficially very similar to its allies, this species is immediately dis- 

 tinguished by the peculiar structure of the antennae of male, and 

 the markedly sinuate termen of forewings. The recurrence of 

 this curious antennal structure in various unrelated genera as a 

 character of not more than specific value is a singular phenomenon. 



273. Y. cap7iites, n.sp. 



(J9. 16-20 mm. Head and thorax fuscous, slightly reddish- 

 tinged, sides of crown sometimes whitish, shoulders rosy-tinged, 

 edged with dark fuscous. Palpi dark fuscous, apex of second 

 joint whitish, tuft moderate, triangular, terminal joint whitish 

 on sides, very long. Antennae and abdomen fuscous. Legs dark 

 fuscous, posterior tibiae paler. Forewings with costa gently arched, 

 apex obtuse, termen rather obliquely rounded; fuscous, indis- 

 tinctly strigulated with dark fuscous; costa rosy-tinged on basal 

 third, with dark fuscous basal dot; an obscure dark fuscous spot 

 in disc at ^; stigmata rather large, very obscure, dark fuscous, 

 plical somewhat obliquely before first discal : cilia fuscous, tips 

 paler. Hindwings fuscous, darker posteriorly; cilia pale fuscous, 

 with darker subbasal shades. 



Toowoomba, Queensland; Mount Lofty, South Australia; in 

 September and October, five specimens. 



55. Thalamarchis, n.g. 



Antennae 4, in ^ simple, basal joint moderate, without pecten. 

 Labial palpi very long, recurved, second joint with appressed 

 scales, terminal joint as long as second, acute. Forewings : 2 

 and 3 tolerably remote, parallel, 7 and 8 stalked, 7 to termen. 

 Hindwings IJ, ovate, cilia i; 3 and 4 connate, 5, 6, 7 tolerably 

 parallel. 



Although showing simple structural characters, the single 

 species forming this genus appears to stand quite isolated, and I 

 am unable to see that it bears near relationship to any form 

 known to me. In its large size and conspicuous colouring it 

 resembles an Oecophorid of the Fhilobota and Hypercallia groups,
