134 Sir G. F. Hampson on 



in cell; 4, 5, 6 from the discocellulars at intervals; 7. 8 

 strongly stalked from upper angle; 9 from angle; 10, 11 

 from cell. Hind wing with vein 2 from close to angle of 

 cell ; 3 from angle ; 4, 5, 6 at intervals from discocellulars ; 



7 from upper angle ; a forked veinlet in cell ; 8 free. 



The genus may be placed in the Tineidse when the limits 

 of the families are better defined. 



Trichocossus albiguttata, sp. n. 



S . Head, thorax, and abdomen clothed with dark brown 

 and white hair mixed ; frons white ; antennae with the 

 branches dark brown. Fore wing red-brown tessellated with 

 rather ill-defined rounded white spots varying in size, with 

 no white spots below vein 1 except two at middle, and none 

 on terminal area except at costa ; a slight darker brown 

 discoidal spot. Hind wing red-brown, the cell and area just 

 below it whitish. 



Hab. Transvaal, Pochefstrom (Ayres), 1 $ type. E.vp.

Gymnelema stygialis, sp. n. 



9 . Head, thorax, and abdomen black. Fore wing black, 

 rather sparsely irrorated with large white scales. Hind 

 wing black-brown. Underside of fore wing with series of 

 white spots on costa except towards base. 



<J . Wings shorter and comparatively broader, especially 

 the hind wing ; fore wing with veins 9, 10 coincident, the 

 white irroration slight, cilia pure white except at torn us ; 

 hind wing with some white in cilia towards apex. 



Hab. Transvaal (Pead), 1 <£, White R. (Cooke), 1 9 type, 

 Johannesburg (Cook), 1 £ ; Natal, 1 9 • Exp., $ 18, 



9 30 mm. 



Fore wing with veins 7, 8 from the areole, 9, 10 stalked 

 from the areole in female, coincident in male, or 7, 8 also 

 stalked from the areole. 



The genus belongs to the undefined borderland between 

 the Cossidse and Tineidse ; the distinction will probably be 

 proved to be that the former has vein 1 c of the fore wing 

 fully developed and reaching the termen or becoming coinci- 

 dent with 1 b, the latter slight and not reaching termen. 



Gymnelema rougemonti, Heylaerts, from Delagoa Bay, the 

 type of genus, has veins 7, 8 stalked from the areole and 9, 



10 from the areole in the single female described. Heylaerts 

 describes the larva as a case dweller. 



Gymnelema vinctus, W]k., = incanescens, But]., has veins 7, 



8 from the areole and 9, 10 stalked or from the areole. '•
