groove. Tegulse large and distinct; wings reduced to small oval 
bulbs, but little longer than the tegulse, lying in depressions at 
the side of the mesonotum and scutellum. The latter small, 
broader than long with a pair of deep, nearly conflunt fovese 
at the base. Propodeum a little longer than wide, sides parallel? 
apex of dorsal face truncate, apical angles each with a minute 
tooth; posterior face nearly perpendicular. Meso and meta- 
pleurse and sides of propodeum obliquely rugoso-striate; pro- 
podeal spiracle elongate, almost linear. Abdomen not depressed, 
nearly circular in cross-section, strongly bent downwards at apex, 
the upper surface smooth, without any constrictions, the tergites 
extending well down on the sides; first one almost as long as 
second; third, fourth and fifth each about two-thirds as long, 
subequal; apical segments short. Anterior femora and tibiae 
greatly thickened; middle legs slightly so; hind legs moderately 
slender. Tarsi, especially the four posterior ones long and 
slender; inner spur of hind tibia oval, pad-shaped, outer one nar- 
rowly spatulate, but not pointed at tip and less than one-third 
as long as the metatarsus. Claws slender, simple. 
Type from Stony-brook Reservation, Boston, Mass., May 8, 
1921 (W. M. Wheeler); paratype from Wyandauch, Long Island, 
N. Y., May 1, 1910 (W. T. Davis) 
I have stated that the specimens are males as the antennae are 
10-jointed although I cannot be sure, and Kieffer was also in 
doubt as to the sex of the Chilian species. Both sexes of the 
European form are practically apterous, although the Chilian, 
P. angusti'penne has very short, strap-shaped wings. 
As already noted, P. nearcticum is very close to P. rufescens, 
but the comparative lengths of the antennal joints are different. 
Several European varieties have been based on slighter variations 
of the same sort, however, and the American form may possibly 
prove to represent only a variety or subspecies. Pedinomma is 
not known from Asia, but it is a very rare insect in Europe and 
may quite possibly range far to the east of its present known 
habitat.
