cilia thrice as broad. Abdomen moderate, stout. Legs rather 

 short, posterior tibiae compressed, very hairy. Fore-wings with 

 6 veins ; 1 and 2 simple ; 3, 4, 5 to costa, forming branches of 

 subcostal vein ; no cell. Hind-wings without cell ; median 

 simple ; submedian very obsoletely twice-branched. 



Allied to the preceding genus, but distinguished by the much 

 broader wings, the antennae shorter than fore-wings, and the low 

 type of neuration. The imago in repose sits closely appressed to 

 surface. 



Arct. ursinella, n. sp. 



< $ . 3|-"-4". Head, palpi, thorax, and abdomen deep ochreous 

 brown. Antennae dark fuscous. Legs brownish-grey. Fore- 

 wings unicolorous rather deep ochreous-brown ; cilia fuscous-grey. 

 Hind-wings and cilia dark fuscous-grey. 



Beaten commonly from Acacia decurrens, at Parramatta, and 

 also at Bulli, in October. 



LYONETID^E. 



STEGOMMATA, n. g. 



Head roughly tufted on crown, face smooth ; no ocelli ; tongue 

 moderate. Antenna) as long or longer than fore-wings, slender, 

 filiform, basal join dilated into a moderate eyecap, fringed in 

 front. Maxillary palpi obsolete. Labial palpi moderately short, 

 straight, rather drooping, smoothly scaled. Fore-wing elongate, 

 narrow, pointed, apex caudate. Hind- wings linear-lanceolate, 

 cilia five times as broad. Abdomen elongate. Legs moderate, 

 slender. Fore-wings with 8 veins, cell closed, 1 strongly furcate 

 at base, 5, 6, 7 to costa. Hind-wings without cell ; median twice- 

 branched ; submedian apparently simple. 



This genus is nearly allied to Lyonetia, Hb., and the neuration 

 is essentially identical ; it differs in the strongly- tufted, rough
