 et P. Chap^, 1899, in Mus. Paris). 



This species approaches D. nigricejps in colour, but it 

 is nearer to D. grccni in structure ; it may be easily 

 confused with the former.

This is the species whose post-embryonic development 

 was investigated by Mr. Green, together with that of D. 

 gerst^ckeri. It is undoubtedly distinct from the D. nigriceps 

 of Kirby, from Hong Kong, with which it is confused in 

 collections.
