84 RHOPALOCERA AFRICJE AUSTRALIS. 



Genus PENTILA. 



Pentila, Boisd. 

 Tingra, Boisd. 



IMAGO. Head small : antenna short, with a short, thick, 

 elongate-ovate club ; palpi very small and short, closely 

 appressed to head. Wings large, elongate, entire. Fore-wing: 

 costa moderately arched, hind-margin convex. Hind-wing .- 

 ovate, hind-margin being strongly convex. Legs short, thick, 

 scaly : fore-legs of $ small, imperfect. Abdomen elongate, 

 thickened at extremity. 



The species composing this singular and aberrant Lycseni- 

 deous Genus are of weak and delicate structure, reminding 

 one to some extent of the Moths called Geometrte, a 

 resemblance increased by their faint colouring speckled with 

 blackish. Five species have been discovered in Western 

 Tropical Africa, one only of which is as yet known to inhabit 

 the South. This species seems widely spread, Hopffer 

 recording it from Queriraba, on the coast of Eastern Africa.
