06s. Dahlbom (Clavis, fig. 6) figures a male saw-fly, which he named 

 N. Klugii, and which Thomson regarded as lilineatus, but this is not

Antennae longer than half the body, thin, filiform, decreasing in 

 thickness towards the apex, the third joint scarcely longer than the 

 fourth, the rest becoming gradually shorter ; the colour is black above, 

 luteous beneath. Head narrower than the thorax, smooth, shining, 

 covered with pale pile; the vertex thick, rounded, the front also 

 rounded ; the sutures and f oveae distinct, moderately deep ; the epistoma 

 convex, distinct. Clypeus deeply notched, the incision oval ; the apex 

 of labrum a little narrowed, luteous, the face from below the antenna? 

 pale luteous, moderately produced in front ; the mandibles are dark 

 brown, the vertex luteous, the eyes and ocelli black. Thorax luteous, 

 at the sides smooth and shining, pubescent ; the pleurae and apex of 

 scutellum are punctured ; there is a black band across the breast. The 

 abdomen is longer than the head and thorax, flattish, broadest in the 

 middle, the apex narrowed, compressed, almost truncate ; the cerci are

 of the saws very broad and thick ; the legs are luteous, the spurs short. 

 Wings a little smoky, clearer at the apex ; costa and stigma yellowish, 

 the latter black at the base, the nervures deep black. The first trans- 

 verse cubital nervure is usually faint ; the second cubital cellule is long 

 and has a horny point at its apex ; the third is a little more than half 

 the size of the second, straight, scarcely widened at the apex ; the 

 fourth is about one-quarter longer than the third ; the second recurrent 

 nervure is received in front of second transverse cubital.
