Jloh. Barrackpme, Bengal {Rothnei/). 



Antenna' as long as the head and thorax united, stout; the 

 scape covered with long pale hair. The front, face, and 

 clypeus are thickly covered with white pubescence ; there is 

 an indistinct keel on the centre of the face and a distinct one 

 down the centre of the upper two thirds of the clypeus ; the 

 front, vertex, and occiput are thickly covered with long white 

 hair. Mesonotuin closely rugose and covered with a white 

 pile ; the scutelluni is more strongly punctured and its apex 

 is fringed with long black hair. Postscutellum thickly 

 covered with longish white pubescence. The basal area of 

 the median segment is irregularly, longitudinally, but not 

 closely, striated; the area behind it is smooth, the rest of the 

 segment is punctured and covered with white pubescence, 

 rieurffi thickly covered with longish white hair. Legs 

 b'.ack, thickly covered with white hair; the calcaria rufous; 

 the hinder tibiaj become gradually, but not much, dilated 

 towards the apex ; the metatarsus is not thicker than usual. 

 The basal segments of the abdomen are closely punctured, 

 except at the apex ; the basal segments of the abdomen and

 and its apex is bilobate. 



Comes close to N. tridescens, Sm,, which may be known 

 from it by the basal area of the median segment being longi- 

 tudinally rugose, while in the present species it bears irregular 

 widely separated keels.
