482 AUSTRALIAN LEPIDOPTERA, 



segmental margins white. Legs ochreous-grey. Forewings 

 elongate, moderate, costa evenly arcbed, apex somewhat pro- 

 minent, termen sinuate beneath apex, thence obliquely rounded; 

 seven to below apex; fleshy- white, becoming whitish on costal 

 third of wing; all veins neatly outlined with clear white, and 

 more or less finely edged on either side with dull fuscous, espe- 

 cially beyond cell; cilia light fuscous. Hindwings grey-whitish; 

 cilia ochreous-whitish. 



Broken Hill, N.S.W.; one specimen, in July. 



I should be inclined to propose a new genus for the reception 

 of this species, but for paucity of material. The type was beaten 

 from Casiiarina, twelve years ago, and I have not met with a 

 second specimen. The termination of vein 7 of forewings is at 

 variance with the characters of Linosticha. 



LiNOSTICHA SERICOPA, n.sp. 



(J. 16 mm. Head, palpi, antennae, and thorax dark fuscous. 

 Abdomen greyish-ochreous. Legs dark fuscous, posterior pair 

 yellow-ochreous. Forewings elongate, moderate, costa gently 

 arched, termen rather strongly oblique; dark fuscous, faintly 

 coppery-tinged; markings obsolete; cilia dark fuscous, mixed 

 with grey at anal angle. Hindwings pale ochreous-fuscous; cilia 

 pale yellow, terminal half mixed with fuscous towards apex. 



Broken Hill, N.S.W.; one specimen, in November (at light). 



Not unlike some species of Scieropepla {Xyloryctidai). 



Tkachyntis mimica, n.sp. 



(J. 25 mm. Head and thorax fuscous, patagia mixed with 

 grey-whitish. Palpi fuscous-whitish, becoming white internally 

 on basal joint. Antennae and legs fuscous, posterior tibiae and 

 tarsi tinged with ochreous. Abdomen ochreous, segmental 

 margins whitish. Forewings elongate, modeiate, costa gently 

 arched, termen rounded, oblique; dull bronzy-ochreous, more or 

 less minutely irrorated throughout with fuscous, which is more 

 dense on upper half of wing, except towards termen; two fuscous 

 discal spots, placed longitudinally, at one-third and two-thirds 

 from base, both edged posteriorly with a spot of ochreous-whitish;
