This genus was originally defined by Kieffer as recognizable by the 
subconical, subsessile antennal segments of the female and with the 
tip of costa nearer the second than the third vein. The palpi are 
quadriarticulate, the claws denticulate and the pulvilli well devel- 
oped. Later, Kieffer states that the claws are arched and not or 
hardly dilated, while the antennal segments of the male are eccen- 
tric, with a stem about three-fourths the length of the basal enlarge- 
ment and with crenulate whorls as well as whorls of hairs, the third 
vein extending to the apex of the wing. The basal clasp segment 
is stout, lobed internally, while the terminal clasp segment is stout

at the base, greatly expanded distally, swollen and broadly rounded 
apically. The female antennae are subconic or subovoid, with a 
very short stem and bearing subapically a broad, chitinous collar. 
The thickened anterior border of the wing extends almost to the 
fourth vein. Type Prionota pini Kieff. A mntimberof 
American species have been provisionally referred to this genus.
