1888.] FROM EQUATORIAL AFRICA. 73 



The female is in the Museum from the Victoria Nyaiiza, and I 

 formerly supposed it to be that sex of T. hetaera ; it is somewhat like 

 a large edition of T. jobina $ , but has a few scales of magenta-red 

 in each of the white spots towards apex of primaries. This species 

 should stand between T. eunoma and T. heteera.

S . Size of T. ione or slightly smaller. Wings above white ; 

 primaries with narrow black costal margin ; the base sprinkled with 

 black scales ; apical area blue-black, with dentate-sinuate inner edge, 

 and crossed by a wide belt of brilliant changeable purple (wider and 

 bluer than in T. ione) ; the spot at end of cell scarcely visible, 

 reduced to two or three scales ; secondaries white, witii blackish 

 veins terminating in minute black spots on the outer margin. Wings 

 below white, the apex of primaries and whole of secondaries very 

 pale sulphur-yellow, crossed by well-defined black veins terminating 

 in small subconfluent black spots on the outer margin ; costal 

 margin of primaries black ; a black dot at the end of the cell : 

 secondaries with the basal half of the costal margin yellow ; a black 

 transverse dash from costal to subcostal vein, forming the commence- 

 ment of an ill-defined oblique stripe, indicated by scattered black 

 scales as far as the third median branch. Expanse of wings 

 57 millim. 



2 . White above ; the base rather broadly irrorated with blackish 

 scales ; primaries with the costal margin black ; a broad external 

 blackish border crossed by black veins, widest at costa, gradually 

 diminishing in width from costa to first median branch, to which 

 point it is internally dentate-sinuate and traversed by six white spots 

 in an arched series, narrow and internally widely sinuated from first 

 median branch to submedian vein ; a black spot at the end of the 

 cell ; a transverse blackish spot at external third of interno-median 

 area : secondaries with a marginal series of large subconfiuent 

 blackish spots crossed by black veins ; a blackish subapical oblique 

 stripe from costa, connected with the macular border by black veins : 

 body quite normal. Primaries below white, the costa and apical 

 area pale yellow ; veins towards outer margin dark brown ; a sub- 

 apical series of angulated brown dashes ; a black spot at the end of 

 the cell ; two small black spots on interno-median area and three 

 brown triangular spots at end of first median branch, interno-median 

 fold, and submedian vein : secondaries pale yellow, base of costal 

 margin and a spot at the end of the cell bright yellow ; veins, an 

 elbowed stripe beyond the middle, and the fringe excepting at the 

 extremity of the interneivular folds, dark brown : body below white.
