2 . Very close to T. caffra, but easily distinguished from the 

 fact that the hyaline triangular spot in the cell of primaries fills 

 the upper instead of the lower angle ; also the inner edge of the 

 hyaline belt from median vein to apex is not irregular but forms a 

 direct oblique line, the second division from the apex being much 

 elongated backwards ; the brown border of the secondaries is also 

 narrower. Expanse of wings 37 millim.

 utterly in the character of the antennae, wliich are solidly bipec- 

 tinated, the pectinations widely separated and eniitthig short 

 bristles: the primaries with only four brajichos to the subcostal 

 vein, the fork of the united third and fourth branches being longer 

 than in Setinochroa and more divergent ; secondaries with the sub- 

 costal furca considerably shorter and the footstalk consequently 

 very much longer than in that genus.
