ee. Pygidium with third pair of lobes not incised; median 

 pair of lobes broad, as broad as long, sloping on both 

 margins to blunt point, minutely dentate, proximal half 

 of margins subparallel; second pair of lobes incised, 

 mesal lobelet much larger than lateral, similar to median 

 lobe, more or less notched on each side, lateral lobelet 

 bluntly pointed, entire; third pair of lobes short, broad at

 nute, subtriangular in outline; third pair of lobes similar 

 in size and shape to second pair; plates of median incisura 

 shorter than lobes, those of other incisurae and lateris vari- 

 able in length, arranged 2, 2, 3-4, 3, those of each lateris near 

 a lobe; brevaceratubae few in number. — Australia on Hymen-
