of which I suspect it may be the female. No two of the three 
females are alike in detail, but the material is quite insufficient 
for a proper understanding of the species. The clypeus is 
normally extraordinarily dull, and I suspect this is due to some 
special excretion, as a specimen I possess shows some more shining 
spaces and some dull raised lumps, as if the excretion had not 
been distributed in the usual even manner. ‘The scutellum is 
unarmed, and the second ventral segment is very strongly and 
abruptly raised behind the transverse suleature.

Clypei pars deplanata antice nigra, postice rufa. Ale fere 
hyaline, parte costali perconspicue infuscata. P. vulnerato 
structura evidenter cognatissima, sed: major, clypeo nitidissimo, 
mesonoto magis nitido, abdominis segmento 2 dorsali, basim 
versus, leviter convexo, facile distinguenda. Long. 10 mm. 
The markings are red, as in various other species from Western 
Australia, which it entirely resembles superficially. I cannot be 
certain whether the clypeus is always highly polished, as in the 
single example described, or whether it may not be sometimes 
dull, as in vulneratus, but in any case the species is easily 
distinguished structurally by the small convexity of the second 
abdominal segment, which in vulneratus, viewed laterally, rises 
convexly above the first to a distinctly more conspicuous degree.
