separatis ornato), fasciis integris, aut vix interruptis, maculis 
propodealibus rufis aut flavo-rufis, segmento 2 abdominali maculis 
basalibus carente, distinguenda. do ¢ tegulis minutissime evi- 
denter punctulatis et clypeo distinctissime emarginato, facile 
distinguendi ; a P. simillimo clypeo distincte emarginato, primo 
aspectu separandi. Long. 8-9°5 mm. 
The apical margin of the second abdominal segment is quite 
strongly depressed and rather wide; ventrally behind the sulca- 
ture it is depressed, and very remotely punctured. The apical 
ventral segment of the male is subconvex and clothed with erect, 
but not long, hairs.

On account of its very narrow second segment of the abdomen, 
this species appears rather out of place in this division, the first 
segment appearing less small in comparison with the hinder 
parts. It varies a good deal in details of coloration, the second 
abdominal segment sometimes having two conspicuous rufescent 
basal spots and sometimes lacking these. The lines along the 
outer orbits are usually distinctly bicolorous, and are abbreviated 
in some specimens. The tegule have a minute and plentiful 
puncturation, and generally a few larger, but feeble, punctures 
are noticeable.
