evaluate the significance of the variation noted in the structure and colour of 

 pulverosa. For the present no subdivision has been attempted. 



Biology. E. E. Piatt (1921 : 131) recorded the larva, under the name secutaria 

 Guenee, feeding on Dichrostachys nutans Bentham [=D. cinerea (Linnaeus) Wight 

 & Arnott] (Leguminosae) . 



Distribution. Mozambique, Rhodesia, Natal, Transvaal, Orange Free State, 

 Cape Province, Botswana, South West Africa. 



Material examined. 



Zamarada pulverosa Warren was described from two female specimens in the 

 Rothschild collection from South Africa. According to Prout's unpublished notes 

 in the BMNH, the original specimens are lost; this conclusion has been confirmed 

 by a further fruitless search. Gaede's note (1915 : 123) that he had borrowed 

 type-material is evidently based on a misunderstanding, for he was almost certainly 

 loaned what were believed to be typical examples agreeing with the original 

 description. 



In order to stabilize the use of the name pulverosa a male neotype has been 

 designated, the male displaying better diagnostic characters than the female.
