The various forms of Orthopterous insects which form the 
subject of these notes were collected by Mr. A. Zietz during the 
latter half of 1893, at Lake Callabonna, as bye-work whilst 
engaged there in the exhumation of Diprotodon and other fossil 
remains. The specimens referred to form part of the entomologi- 
cal collection in the South Australian Museum.

The single specimen obtained appears to resemble P. Ger- 
manica, L., but is much larger, the pronotum less transverse, the 
black stripes of unequal width, and the anterior margin distinctly 
emarginate ; whilst the branches of the radial vein of the elytra 
only diverge at the base, being otherwise parallel throughout.
