474 DESCRIPTIONS OF AUSTRALIAN MICRO-LEPIDOPTERA, 



ous ground ; from B. humerana it differs widely in the absence of 

 the streak along- costa, and in the presence of the oblique streak 

 from inner margin near base. It is allied to B. clarana, but 

 larger, broader-winged, and more clearly marked. The female 

 has a somewhat deeper tinge than the male, and the markings 

 are slightly broader. 



Occurs rather plentifully near Sydney, Parramatta, and Bulli, 

 New South Wales ; and at Brisbane and Toowoomba, Queens- 

 land ; in low scrub, from September to November, and in January 

 and March. I have thought it necessary to alter Walker's 

 barbarously formed name to an admissible shape. 



5. Dich. (?) humerana, Walk. 

 (Conchjlh humerana, Brit. Mus. Cat. 366.) 

 7". Thorax pale yellowish. Forewings in form nearly as B. 

 fmciceps ; pale clear ochreous-yellow ; a dark fuscous line along 

 costa from base to one-third ; a slender dark fuscous rather oblique 

 transverse streak from costa beyond middle nearly to inner 

 margin before anal angle. Hindwings pale grey; cilia pale 

 yellowish. 



Walker's type, from which the above diagnosis is taken, has 

 no head, and is otherwise in poor condition ; I could not determine 

 its generic characters, and can only conjecture that it may be 

 referable to this genus ; but it is such a distinct species that it 

 could not well be passed over without notice. It may belong to 

 a quite different group. 



The locality is given as South Australia. 



6. Dich. (?) retractana, Walk. 



(Bichelia retractana, Walk., Brit. Mus. Cat. 322). 



7". Head and thorax pale ochreous. Forewings moderately 



broad, costa rather strongly arched towards base ; pale ochreous, 



somewhat brownish-tinged ; two small dark fuscous costal spots,
