and a third less elongate in disc beyond middle : cilia pale grey 

 mixed with white, with two cloudy darker lines. Hindwings pale 

 grey ; cilia grey-whitish. 



Mount Lofty, South Australia ; one specimen received from 

 Mr. E. Guest, who states that it is not scarce. 



45? Saropla, Meyr. 



Head loosely scaled, sidetufts large, spreading, somewhat pro- 

 jecting between antennae. Antennae moderate, in £ moderately 

 and evenly ciliated (1), ba^al joint moderate, with strong pecten. 

 Palpi moderate or long, second joint reaching or considerably 

 exceeding base of antennae, densely scaled, beneath with a short 

 loose spreading tuft towards apex ; terminal joint shorter or much 

 shorter than second, slender, oblique, often partially concealed. 

 Thorax smooth. Forewings elongate, hindmargin more or less 

 concave, oblique. Hindwings narrower than forewings, elongate- 

 ovate or broadly lanceolate, cilia 5 to 1^. Abdomen moderate. 

 Posterior tibiae clothed with very long hairs. Forewings with 

 vein 7 to hindmargin, 2 from distinctly before angle of cell. 

 Hind wing normal, cell sometimes elongate. 



It seems unnecessary to divide this genus, although there is some 

 range of structural variation in the different species. & hyperocha 

 is the neai-est to the ancestral form ; S. cleronoma represents an 

 extreme of retrograde development. The genus is nearly allied to 

 Pleurota, and may probably be regarded as an offshoot from an 

 early form of that genus. It is further interesting as having 

 considerable direct affinity with the European genera Holoscolia 

 and Topeutis (most visible in S. melanoneura) which are probably 

 offshoots from it.
