 species is the type of Perseetarda, Hmps., a genus recognized 

 both by Sir George Hamppon and Mr. Meyrick, as dis- 

 tinguished by the frons forming a slight rounded prominence 

 with a corneous plate below it. Having rubbed off the palpi 

 and frontal scales from examples of ewingii, loreyi, and 

 ahdominalis, I can find no difference between them. 



SiDERiDis viBicosA, u. sp. (vlhieosus, full of small scars). 



(S , 35 mm. Head whitish with a few fuscous scales. 

 Palpi 1^, second joint with loosely appressed scales, terminal 

 joint short; ochreous-whitish, outer surface of second joint 

 partly suffused with grey, with slight fuscous irroration. 

 Antennae grey, paler towards base. Thorax whitish-grey 

 irrorated with fuscous. Abdomen pale grey. Legs pale grey 

 with some fuscous irroration; anterior coxae densely hairy, 

 with purple-grey irroration. Forewings with costa slightly 

 arched, apex rounded-rectangular, termen straight to near 

 tornus, not oblique; whitish-grey suffused and irrorated with 

 dark grey; paler towards base and costa; absence of irror- 

 ation leaves a pale discal spot at f , and a large number of 

 pale transverse strigulae in posterior part of disc; cilia dark 

 grey with a pale basal line. Hindwings with termen wavy; 

 whitish, towards margins suffused with grey; cilia grey with 

 whitish basal line, towards tornus wholly whitish. 



Although very inconspicuously coloured the numerous 

 strigulae on forewings distinguish this from any Australian 

 species.
