This fine species, with which I have much pleasure in associating the 

 name of its discoverer, is evidently allied to Diatomineura (Coiizoneura) 

 distincta, Ricardo (East Africa and Abyssinia), to which, in both sexes, it 

 presents a general resemblance in appearance, besides agreeing with it in 

 the character of the sexual colour-dirhorphism. Apart, however, from its 

 g^enerally larger size, iHatomineura neavei can at once be distinguished from 

 IJ. distincta by, in both sexes, the darker coloration of the legs, and by the 

 upper portion of the tumid region of the face being entirely shining, instead 

 of wholly pollinose, as in D. distincta ^, or pollinose in the middle, as in 

 I), distincta ? . Furthermore, JD. neavei ^ is distinguished from D. dis- 

 tincta (^ by the ridge of hair above the base of tlie wing on each side being- 

 dark brown or blackisli instead of pale yellowish, while in the case of the $ 

 the grey bands on the hind borders of the abdominal segments are much 

 more conspicuous in D. distincta than in I), neavei, and the hair on the first 

 abdominal segment of the latter is ochraceous instead of pale yellow.
