Pristiphora Konuow, Deutsche Ent. Zeits., xxxtv, 1890, p. 238. 
Body short, ovate; clypeus truncate at apex; pentagonal area obsolete; claws 
either with subapical tooth or bifid; first transverse cubital of anterior wings often 
wanting or hyaline; eighth (seventh?) dorsal segment of the male carinate, carina 
not prominent at apex; sheath of female with rather dense scopa at tip.—Konow. 
The species of this genus form a fairly well defined group, but are 
often referable rather from the sum of the characters than from any 
particular feature. Theabsence of the first cubital nerve is by no means 
coustant, even in the same species, although usually a good generic 
character and to be relied upon. “The claws are sometimes very evenly 
notched at the tips, but not deeply so. When this is the case, however, 
the smooth vertex, which is a very constant characteristic of the genus, 
taken in connection with the other characters, will usually determine 
the true affinities. Very little is known by actual rearings of the habits 
of the species, but in this particular they probably present no striking 
peculiarities. A numberof them feed on willow and P. idiota Norton is 
an important enemy of the cranberry.
