the costa, but, in JV. violaceus, the spinules are not infrequently 

 wanting on the hind tarsi, and sometimes, though rarely, also on 

 the middle tarsi. 



Table of Species. 

 l.(12)Prothorax with sides not sinuate before basal angles. 

 2.(9)Prothorax with basal angles obtuse, lateral border not widely reflexed 



just before basal angles.

... 46. A 7 , rainbowi SI. 



4.(3)Prothorax widest before middle, obliquely narowed to base.

 6.(5)Prothorax lightly narrowed to base, with at least metallic tints neat- 

 base.

47. N. gippsiensis Cast. — I found this species in Victoria, at 

 Marysville and Jamieson; it is also found at Mount Buffalo and 

 Talangatta. 



50. A 7 ", macoyi Sl.,( = N. howitti SI.), varies considerably in size 

 and appearance. The interstices of the elytra are convex in <J, 

 depressed (rarely a little convex) in £. Sometimes, and more often 

 in 9 than in <J, the prosternum is bordered along the whole of 

 the anterior margin; in my Revision of 1902, too much import- 

 ance was attributed to this character. N. macoyi occurred to me 

 plentifully at Jamieson, on the upper Goulburn River, last De-
