The general aspect of this species is very peculiar ; the extreme 

 regularity of the transverse strigulae between the veins produces 

 an appearance of geometrical reticulation similar to that of the 

 vvebs of some spiders. 



Five specimens taken at rest on fences in Sydney, from 

 September to December. 



2. Proselexa, n. g. 



Thorax smooth. Antennae in male thickened, thinly and shortly 

 ciliated. Palpi short, porrected, second joint roughly scaled 

 above, terminal joint almost concealed. Fore wings elongate, 

 narrow, costa in male simple, gently arched, hindmargin very 

 oblique, rounded. Hindwings elongate, broader than forewings. 

 Forewings with veins 7 and 8 separate. Hindwings with veins 

 3 and 4 remote at origin and parallel, 5 equidistant from 4 and 

 parallel, 6 and 7 long-stalked. 



This genus belongs to the group in which veins 3 and 4 of the 

 hindwings do not rise from the same point. In this group it is 

 distinguished from all except Isochorista by having veins 4 and 5 

 of the hindwings not only widely remote at origin but parallel 

 throughout ; from Isochorista it differs by the separation of veins 

 7 and 8 of the forewings, which in Isochorista rise from a common 

 stalk. 



1. Pros, annosana, n. sp. 



<$ ? . 4J"-5". Head and palpi white. Antennae greyish- 

 ochreous. Thorax white, margins spotted with pale ochreous. 

 Abdomen whitish-ochreous. Legs ochreous- white, anterior tarsi 

 suffused with fuscous at base of joints. Forewings white, 

 irregularly strewn with fine fuscous-grey scales, forming indistinct 

 strigulae on costa ; base indistinctly spotted with ochreous ; four 

 nearly straight transverse slender ochreous fasciae, nearly per- 

 pendicular to costa ; first at one-fourth, indistinct, clearest in disc, 

 slightly bent below costa ; second in middle, slightly broader
