? . Eyes less distinctly convergent than in tlie male ; 

 apical joint of the flagellum stout and rounded at the apex ; 

 scutellum without a fovea ; anterior tarsi with v&ry long 

 spines; pygidinm rather strongly punctured. Both sexes 

 are finely and very closely punctured. The fuscous radial 

 patch on the fore wing occupies the whole of the radial and 

 the greater part of the second and third cubital cells. The 

 first transverse cubital nervure is very slightly curved. 



Hab. Mid Luang-wa Valley, Upper and Lower Luangwa, 

 N.E. Ehodesia ; Valley of N. Eukuru, Karonga District, 

 I^yasaland : July to September {S. A. 2\eave).

 as from the eyes. Antennte gradually thickened towards the 

 apex, second joint of the flagellum twice as long as the third. 

 Scutellum without a distinct fovea. Very minutely punc-

 more coarsely punctured, especially towards the a])ex, which 

 is narrowly rounded. Second abscissa of the radius longer 

 than the first, but only halt as long as the third; submediiiu 

 cell of the hind wing tern)inating far bej-oiul the origin of tlie 

 cubitus. The fuscous mark on the radial area of the fore 

 wino- spreads over the greater part of the second and third 

 cubital cells. Pubescence on the thoiajs. ehoit and grey i:^h.
