A very distinct species, diflTei-ing from its congeners in its less 

 angulated elytra, much thinner legs, unarmed femora and elon- 

 gate onychium. In general appearance it comes nearest to 

 N . fascicularis Pasc, a Central African species which has recently 

 been taken by Mr. P. A, Sheppard at Amatonga's on the Beira 

 Railway.
