tip of witjg below end of second vein very faint, indistinctly 

 bifurcate in tiist submarginal cell; a group of tliree some- 

 what more distinct light marks in basal half of second sub- 

 marginal cell, |)roxiraal mark the longest, continued across 

 first submargiual cell to second longitudii al vein, middle 

 mark connecting the two branches of third vein, distal mark 

 a mere spot on lower branch of latter ; a small, roughly 

 circular, light mark in marginal cell at distal extremity of 

 stigma, enclosing a darker centre and with a nearly straight 

 prolongation running downwards across first subraarginul 

 cell to third vein before its bifurcation ; a large light blotch 

 occupying distal extremity of first posterior cell, and a small, 

 shar[ily defined, light spot on lower side of third vein, below 

 end of a|)pcndix to upper branch of latter; usual series of 

 oldique, disconnected, light markings running across poste- 

 rior cells scarcely indicated, but a series of light blotches on 

 hind margii\ in or near distal angles of second, third, and 

 fifth posterior cells, and a larger light blotch round end of 

 sixth vein and in apex of anal cell ; rosette round distal 

 extremities of basal cells incomplete but well defined, a large 

 curved light mark near tip of second basal cell especially 

 noticeable ; first and second costal cells but very slightly 

 infuscated ; discal cell entirely dark, except a single, well- 

 defined, transverse light mark before middle; axillary cell

This handsome species, whicli I have much pleasure in 

 naming in honour of its discoverer, is closely allied to 

 Hieniatopota decora, Walk. (syn. H. dorsalis, Lvv.), which 

 also occurs in Uganda, though its type is fr<jm Natal. The 

 following summary may serve to indicate the chief points in 

 w hich H. brucci differs from H. decora : — trout almost 

 entirely clove-brown, grey colour confined to lateral margins 

 of upp(!r half, aiul a minute Heck below eaciv lateral frontal 

 blackish-brown spot (in //. decora the front is grey, with 

 brown markings) ; median process from grey hind border of 

 thorax pointed instead of usu:dly ending bluntly, lateral 

 processes of same larger, not divided, and extending as far 

 forward as median process ; hind tai'si entirely black, instead 

 of first joint having broad cream-coloured band at base; 

 much greater extent of dark colour in wing, pale marking 

 close to apex quite small and indistinct, discal cell entirely
