Kesembles Tohaniia hipxinctntua, Wulp (' Notes Loyden 

 Museum,' vii. p. 72, 1S85), from West and South Africa, in 

 having two bl.uk si)0ts on the forehead ; but the eyes have a 

 band which Wulp expressly mentions as non-existent in his 

 species, and the abdomen does not agree with his description. 

 I theretore venture t<"> make it a new species.
