and termen at vein 6, then somewhat excurved and to tornus and 

 only distinct on the veins, where it forms more 'or less distinct 

 maculae ; a terminal series of triangular maculae between the veins ; 

 cilia of ground-colour with a distinct broad diffused fuscous line 

 at one-third and a faint and narrow line at two-thirds. Hind- 

 wing whitish, slightly irrorated and tinged towards costa with 

 fuscous; cilia whitish with a faint diffused fuscous Ime at middle. 



Underside whitish ; hind- wing slightly and fore-wing very densely 

 irrorated with fuscous- black, especially towards costa; in fore- wing 

 a somewhat lighter irroration at subtermmal line ; some fuscous 

 terminal stigulae between the veins ; cilia as on upperside. 



Exp. Type 19 mm. ; female type 20 mm. ; male co-types 16-19 

 mm. ; co- types from 17-20 mm. 



Hah. Male and female types from Sawmills (S. Rhodesia), 

 l.ii. 1918; nine male co-types from Sawmills in Feb., 

 Emangeni (S. Rhodesia) in Jan., and Bulawayo, Dec. 

 1919; six female co-types from Emangeni Jan., Saw- 

 mills, Feb., Bulawayo, Dec, Mazoe (S. Rhodesia), Dec. 

 1919. 



I have many other males from the same localities and 

 collected at the same time. A female in the Transvaal 

 Museum from the Waterberg distr. (Transvaal) most 

 probably belongs here also, but is in too rubbed condition 

 to be certain. 



Perhaps this species requires to be placed in a genus 

 of its own, for the fore-wing has veins 3, 5 on a stalk; 

 however, some species of Rhinaphe have these veins con- 

 nate. Antennae of male serrate at lower half and ciliated 

 over the whole length ; in female simple and ciliated.
