Mr. H. T. Stainton on South African Tinelna. 221 



The species I proceed to describe briefly are — 



1. Tinea rutilicostella, n. sp. 



2. Tinea Gigantella, n. sp. 



3. Tinea purpurea, n. sp. 



4. Adela Natalensis, n. sp. 



5. Ceromitia IVahlbergi, Zeller. 



6. Hyponomeuta fumigatus, Zeller. 



7. Hyponomeuta Africamis, n. sp. 



I trust that when Mr. Trimen next visits us, he will bring back 

 some more species of interest. 



1. Tinea rutilicostella, n. sp. 



Alis anticis saturate brunneis, vitta dorsali lutea, macula disci 

 hyalinali, costa pone medium angustissime lutea. 



Exp. al. 8 lin. 



Allied to Tinea Ferruginella, but larger and darker; the edge 

 of the dorsal streak more of a straight line ; but the most dis- 

 tinctive character is the edge of the costa being yellow beyond 

 the middle, as in T. Imella. 



A specimen was taken at light in November, at Knysna. 



2. Tinea Gigantella, n. sp. 



Alis anlicis luteo-ochraceis, parum nitidis, immaculatis ; alis 

 posticis griseis, luteo-ciliatis. 



Exp. al. 1 m. 1 lin. 



Allied to Tinea BiselUella, but of gigantic proportions, being 

 far larger than Tinea ochraceella. From both those species it is 

 readily distinguished by the more yellow tinge of the anterior 

 wings and by the bright yellow cilia of the posterior wings. 



Two specimens were taken at light in February, at Knysna. 



3. Tinea purpurea, n. sp. 



Alis anticis sordide seneis, vix purpureo tinctis immaculatis ; 

 alis posticis dilute purpureis ; capite luteo. 



Exp. al. 9 lin. 



Not closely allied to any known species; the purplish hind 

 wings remind one of T. misella ; but the unspotted anterior 

 wings of a dull bronzy colour, slightly tinged with purple, 

 abundantly distinguish it from that species. 



One specimen taken at Knysna in October, sitting on the 

 blossom of a composite plant (^Senecio?).
