8. Descriptions of African Micro-Lepidoptera. 

 By E. Meyrick, B.A., F.R.S., F.Z.S. 



[Received June 13, 1907.] 



This paper is a contribution towards the knowledge of the Tor- 

 tricina and Tineina of the African region, which are at present 

 very little known. The material for it was received from various 

 collectors, but for the greater part of it I am indebted to Mr. A. 

 J. T. Janse, of Pretoria, whose specimens are also particularly 

 notable for their fine condition. Mr. Janse further furnished 

 notes on localities and time of appearance, based on additional 

 examples retained by himself besides those which he sent me. 

 in addition to some known species recorded from Africa for the 

 first time, 108 species and 10 genera are described as new.

This species, described from India and Ceylon (Journ. Bomb. 

 ]^. H. Soc. xvii. p. 976), I possess also from Grahamstown, Cape 

 Colony, and the island of Reunion.

 obsolete) ; central fascia rather narrow, sometimes with a few"
