ference in colour, and thorax not " considerably longer than

 the Van de Poll Collection, as from the Richmond River.

 tate, eighth wide; humeral angles strongly dentate : fifth joint 

 of posterior tarsi with four fine setules beneath. Nitid; pro-

Hah. — N.S.W.: Acacia Creek (Sloane). Coll. Sloane. 



Two specimens (<J) occurred to Mr. H. J. Carter and me at 

 Acacia Creek (six miles south from the Queensland Railway 

 town, Killarney) in December. It is a member of the opacicollis- 

 group, of which it is by far the largest species. The wide, eighth 

 elytral interstice, and smooth prothorax together distinguish it 

 from all the other species of the group, except N. illidgei SI.
