Two females, found at Salisbury in Southern Rhodesia by D. Dodds ; 

 and a third, taken at Durban in Natal by W. Haygarth. I have 

 recorded both sexes from Algeria, Khodesia, Transvaal, Mashonalaud, 

 East Africa, Nyassaland and Uganda in ' Revision of the Ichneuino- 

 nidae,' 1915, pp. 95, 96 ; at the latter page the words " C. instructor " 

 should be substituted for " the last." Nothing is yet known of its 

 hosts.

Marley has considerably extended the known range of this species 

 by the capture of a female at Stella Bush, near Durban, Natal, early in 

 1915. I was only able (lib. cit. supra) to record it from East Africa.
