The teeth at veins 4 and T of hindwing are much stronger in ? than in c?. 

 In both sexes there is a conspicuous furrow running longitudinally from base to 

 outer margin along and beyond cell in both wings above, with a corresponding 

 ridge on the underside ; this, being paler, shows more clearly in the darker ? . 



51. Gathynia nigella spec. nov. 



Forewing: costal margin broadly velvety-black; rest of wing blurred grey, 

 separated into two wedge-shaped areas by a brownish-black wedge running between 

 cell and submedian interval ; the inner margin below vein 1 also black ; traces of 

 two darker transverse lines parallel to outer margin, antemedian and postmedian ; 

 fringe black. 



Hindwing: with more than costal half blackish brown, with two short thick 

 very black lines beyond cell ; the costa itself at base also black ; inner margin 

 below vein 1 black ; the furrowed space white, the enclosed pencil of hairs slightly 

 ochreons. 



Underside of forewing dull dark grey, with a blackish cloud on outer margin 

 at middle ; of hindwing whitish, greyer towards margin. 



Head and thorax deep black ; abdomen grey ; vertex snow-white ; antennae 

 dark. 



Expanse of wings : 24 mm.

Homoplexis gen. nov. 



Forewing : short and broad ; costa straight, convex before apex ; outer margin 

 curved, as long as inner margin, which is straight. 



Hindwing : truncate from 8 to 7, then straight to a slight tooth at 3, thence 

 curved to anal angle in ? ; in the <$ the area below submedian fold is shortened, 

 and contorted, without scales, and contains a large tuft of hairs, much as in 

 Dirades. 



Nenration as in Epiplema. 



Type : Homoplexis planimargo Warr. (Epiplema). 



52. Homoplexis planimargo. 



Epiplema planimargo Warr., Nov. Zool. xiii. p. 74, $ (190G). 



The c? of this species does not differ from the ¥ except in the hindwing, where 

 the fold is whitish and the pencil of hairs ochreons. 



2 <?c?, 1 ?. 



The insect is superficially not at all unlike \Fterotosoma bilineata Warr., 

 but the abdomen of c? is quite normal, without tufts. 



Paroecia gen. nov. 



Forewing : short and broad ; costal and outer margin curved, the latter hardly 

 obliqne. 



Hindwing : broad ; hindmargin bluntly toothed at 7 and 4, vertical and faintly 

 concave between, then creuulate to anal angle. 



Antennae of <S bipectinate ; forewing of c? with a fovea near base above vein 1. 



Nenration as in Epiplema. 



Type : Paroecia acupicta spec. nov.
