The most noticeable feature about it, is the acute sliglitly re- 

 curved posterior angle of the thorax. The punctured depression 

 on the scutellum also is unusually large.

 Hab. Lane Cove, near Sydney. 

 I name this insect after the captor, the late Mr. Turner of 

 Lane Cove. It departs considerably in the rather elongate shape 

 of the "thorax, from the majority of the group in which I place it. 

 The sides are well rounded before the middle, and somewhat 

 narrowed near the base which is truncate, with the angles, sharp, 

 slightly recurved, and impressed.

 The thick clothing of soft reddish hair on the elytra is the 

 most marked charcteristic of this insect.
