 much darker species in all respects ; the praescutal stripes are very 

 broad, further restricting the ground-colour ; pleura and coxae black, 

 excepting a bright yellowish-white mark on the lateral portions of the 

 postnotum, and more yellowish spots on the mesepimerou. The legs 

 are black, excepting the basal quarter of the femora and the tro-

 the venation as shown on Plate XII, fig. 40. Abdomen with the 

 subtermiual black ring occupying all of segments six to eight and the 

 caudal portion of the fifth tergite ; ninth tergite dark yellowish - 

 brown, the outer pleural appendages conspicuously bright yellow.

 general structure as in N. tiyrina, but the lateral lobes much broader 

 and stouter, so that the caudal notch is more V-shaped, the median 

 incision large, rounded ; caudal margin with an abundant pale 

 pubescence that conceals the chitinised teeth beneath ; outer pleural 

 appendage elongate, the tip drawn out into a long point.
