margin some distance before the anal angle, and is followed along 

 its lower half by a pinkish grey space. From the third white 

 costal dot a curved brown externally pale-edged line runs to the 

 middle of the wing towards the angle of the second line, before 

 which it vanishes. Submarginal from the fifth white dot, very 

 indistinct. In the ? the submarginal line is conspicuously dis- 

 tinct, denticulated, internally pale-edged, before which it is preceded 

 by a broadish brown shade. In both sexes is a marginal line of 

 lunules ; fringes in <? grey, in J whitish, with a double basal dark 

 line. Hind wings in tlie <? whitish, pellucid, tinged with fuscous ; 

 dark fuscous along the hind margin ; fringes whitish mixed with 

 grey ; in the ? entirely dark fuscous, darker still towards the hind 

 margin ; fringes mottled dark and light. Under side cinereous 

 freckled with darker, with the apex of the fore wing diffusely, and 

 all the margins of the hind wing concisely, bright orauge-brown or 

 brick-red ; the Unes in the $ very distinct. Head, face, and palpi 

 rufous ; the tips of the latter brown ; thorax and abdomen grey 

 and fuscous mixed ; the last four or five segments yellowish above, 

 each segment ringed with whitish.

Alli^ to Sarmatia divisalis, Wlk., xxxiv., p. 1131, 

 from S. Africa (of which Bertula suhcupralis, Wlk., 

 xxxiv., p. 1167, from Natal, is a synonym), and also to 

 RhcBsena transcissa, Wlk., xxxv., p. 1974, from Austraha. 

 I may here mention that, as the type of Sarmatia is 

 S. interitalis, Wlk., a totally distinct insect from S. 

 divisalis, and as further B. suhcupralis is not a Bertula, 

 the generic name Rhasena must be adopted for the 

 species, and the synonymy will be as follows : — 



RhcBsena divisalis.
