KY E. MEYRICK, B.A., F.E.S. 857 



rather thick, cloudy, more or less interrupted ; a hindmarginal 

 series of black dots : cilia pale whitish-ochreous. Hindwings with 

 hindmargin round ; veins 6 and 7 short-stalked or almost from 

 point ; colour, second line, and posterior markings as in forewings ; 

 median line as in forewings, but suddenly sinuate inwards above 

 middle ; a moderate black discal dot on this, or rarely slightly 

 beyond it. 



Sydney, New South Wales ; Deloraine, Tasmania ; Mount 

 Lofty, South Australia; Geraldton, West Australia; in July, 

 August, November, and December, generally common. It is 

 probably almost universal, but owing to the confusion of species I 

 have rejected localities except where lately verified. On dis- 

 covering the existence of closely allied forms, I took a considerable 

 number of specimens, certainly belonging to the same species, in 

 the early spring round Sydney, and found it to be very variable, 

 especially in the colour of palpi, strength of markings of fore- 

 wings, and depth of colouring ; from the two preceding species, to 

 which it is extremely similar, it can always be distinguished by 

 the relatively much shorter posterior tarsi of (J. A. stipataria, 

 Walk., is probably only a deeper-coloured variety. A. recessata, 

 Meyr. I.e., should be cancelled, being founded on a confusion of 

 two species, and not strictly referable to either.

{Acidalia ojjtivata, Walk. 780). 



(J. 18-23 mm. Head light ochreous, fillet ochreous- whitish, 

 face blackish. Palpi ochreous-whitish, towards apex or wholly 

 suffused with blackish. Antennse whitish, in ^ dentate, ciliations

 times with a few black scales. Legs ochreous-whitish, anterior 

 pair dark fuscous, middle pair fuscous-tinged, posterior tibiae 

 dilated, rough-scaled above, with long pencil of hairs from base 

 lying on inner side, tarsi ^. Forewings with costa posteriorly 

 moderately arched, hindmargin slightly rounded, rather oblique ;
