The Lepidoptera of Broken Hill, New South Wales. 



Part IV. 



By Oswald B. Lower, F.Z.S., F.E.S., etc. 



[Read October 10, 1918.] 



This paper contains a supplementary list of species taken 

 since the first part was published, together with those 

 omitted, and a few new species. I also add the few 

 Rhopalocera taken here. 



Family ARCTIADAE. 

 Subfamily ARCTIANAE. 



565. Spilosoma(?) cosmeta, Low. 



Rather common in April and May ; also occasionally from 

 June to October. I have not yet seen the female, which is 

 probably apterous. 



Subfamily AGARISTIDAE. 



566. Comocrus behri, Angas. 



One specimen, in March. 



This species is known to most Australian collectors as 

 casuarinae, Scott. It varies somewhat in the hind wing, as 

 the yellow postmedian band may be broken into spots or 

 entirely absent, as in the form flexuosa , Wlk. 



NOCTUINA. 



Subfamily AGROTINAE. 



567. Meliceptria aleurota, Low. 



Two specimens in March. The type came from Derby, 

 Western Australia, which habitat was accidentally omitted 

 in the original description (Proc. Linn. Soc. N.S. Wales, 

 1901, p. 641). 



Subfamily CUCULLIANAE. 



568. Ariathisa emboloma, n. sp. 

 One specimen, in May. 



Subfamily ACRONYCTIANAE. 



569. Euplexia melanops, Low. 

 One specimen, at light, April.
