costal edge, — the sub-basal one not extending below subcostal nervure, 
— the median one outioardly dark-edged, hiangnlated {just ahove third

lower extremity joining white of inner-marginal fold at some distance

j The characters emphasised in the above description appear to be thoroughly 
^ constant, and warrant the separation of this form from Sataspes. 
I am not aware of the occurrence of this little species beyond the limits of 
' the Cape Colony, but within those limits it appears to be of wide distribution. 
Near Cape Town I have not found it at all numerous ; there seem to be two 
broods, one in September and October, and the other in March and April. Mr. 
L. Peringuey took some examples in the Namaqualand District in October and 
November 1885 ; and I took a specimen at Eobertson in January 1876.
