Both sexes of this species are quite similar above to giganieus 

 Trimen, except that they have no tails at the anal angle of the 

 secondaries. On the underside of the primaries the spot in the 

 postmedian series between veins 4 and 5 is round, not elongate, 

 and is in line with the pre\aous spots, whilst the submarginal dark 

 line is crenulate, not almost straight as in Trimen's species. Second- 

 aries : the spot in the postmedian series between veins 4 and 5 is 

 not elongated oiit of line with its predecessors, and the crenulate 

 submarginal dark line ceases at vein 4, whilst in giganfeiis it is inter- 

 mittently continued to the inner margin. In size the two species 

 are similar. 



Hab. Congo ; Tanganyika ; West Lualaba. 



Genitalia with the harpagines rather narrower and the termmal 

 sickle larger and slenderer than in gigantens ; the aedoeagus is also 

 rather slenderer, otherwise these organs are closely similar to that 

 species. 



Andi'oconia variable, generally smaller than with the preceding 

 species, occasionally oblong, sometimes oval, with about tAvelve 

 rows of reticulations, the dots (reticulations) being well separated 

 vertically.

(^. Both wings, ujiperside, slightly iridescent greyish lilac, with 

 all the veins showmg finely blackish and a rather prominent dark 

 crescent closing each cell. The secondaries have a dark marginal 

 spot in the interspace of veins 2 and 3, with traces of yellow around. 

 Underside. Both wings creamy grey, sometimes dirty grey. 

 Primary with a black spot edged with white closing the cell, followed 

 by the postmedian series of similarly coloured spots, the three upper 

 ones in a slight arc, the fourth shifted inv/ards, fifth inwards again, 

 below which and slightly outwards is another small spot, sometimes 

 single, sometimes double and sometimes absent; there is no dark 

 marginal or submarginal row. Secondaries with a black basal 

 spot edged with white below vein 1, three subbasal spots below
