$ . Coarsely and closely puiicturefl ; head very broad, the 

 eyes distinctly divergent towards the clypeus ; cheeks nearly 

 as broad as the eyes. Antfiuise inserted rather low down, 

 nearly three times as far from the anterior ocellus as from 

 the base of the clypeus, second joint of the tlat;elluni a little 

 longer than the third. First abdominal segment distinctly 

 broader than long ; pygidial urea coarsely bnt rather sparsely 

 punctured, elongate-ovate, rather broadly truncate at fiie apex. 

 Al)c!ominal segments very strongly constricted, the ventral 

 surface almost smooth. First recurrent nervure received a 

 little before the middle of the second cubital cell, second 

 close to the base of the third cubital cell.

The shape of the clypeus is renuirkable and quite different 

 fiom any other Austialian sjiecies.
