 black, brownish from third joint beneath, and slightly pilose ; meso- 

 notum shining, scarcely punctured ; pleura opaque, punctured ; 

 sternum smooth, shining ; tegulse testaceous. Wings hyaline, nervures 

 for the greater part, and costa and stigma livid white ; first transverse 

 cubital nervure distinct ; third cubital cellule longer than broad. 

 The spurs do not reach to the middle of metatarsus ; claws with a

Agrees with the Ambiguus group in having the 

 antennas brownish beneath, but differs in the punc- 

 tured pleuras, black pronotum, and clypeus. It differs 

 from N. breadalbanensis and its allies in its more shining 

 body, in having the antennas brownish beneath and 

 the pronotum black. It has the legs coloured much 

 as in N. lativentris, but the body is narrower, more 

 shining, and less punctured, the costa and stigma of 

 a more livid white, the third cubital cellule shorter, 

 and the apex of abdomen is more marked with 

 testaceous. 



Taken in Braemar by Dr. Sharp in June.

 indistinct ; the frontal area is not indicated. Clypeus almost transverse 

 at apex. Antennas nearly as long as the head and thorax together ; 

 sheath of saw large, projecting, covered with dense pubescence; the 

 extreme apex of abdomen above dirty white ; cerci small ; the third 

 cubital cellule is a little longer than broad ; the transverse median 

 nervure is received nearly in the middle of the cellule ; the wings are 

 large, being longer than the body. ? .
