and very delicately transversely striated; the wings with their 
nervures piceous, and a fuscous nebulosity covering their disk ; 
the legs with their anterior tarsi slightly ciliated, the intermediate 
tibia and first joint of their tarsi very spinose ; and the posterior 
tibiae strongly serrated, and the first joint of their tarsi also very 
spinose. 
The abdomen shining, with the first and second segments, and 
the base of the third, red; the apical segments somewhat hirsute. 
The g does not differ except in the usual characteristics, 
and the posterior legs having only a few dispersed spines; the 
apical segment of the abdomen is furcate and has on each side 
some curved hairs, and the margin of the sixth ventral segment 
has two lateral incisions. 
In most Cabinets. 
+47 I have an insect almost intermediate between the P. 
fuscus and P. affinis, it having the wings of the former, and 
the metathorax coarsely punctured, with a few transverse 
striz in the centre. I consider it merely a variety of the 
above, unless I should discover more that resemble it. 
This is a common species, but differing rather in habits 
from the others of the genus, as it is found almost exclu- 
sively on the banks of hedge rows. The ¢ is generally 
much smaller than the 9.
