Capside. a8 
L. 31 mm. 
Common on conifers ; could only be confounded with 
the ¢ of Plesiodema or Atractotomus magnicornis, from 
the first the pale deciduous pubescence will distinguish 
it; from the second the slender, pale, second antennal 
joint. 
P, variabilis, Fall. (var. simillimus, D. & S., Saund. ; 
var. Whitei, D. § S.).—Shining; 3 brown, ? very vari- 
able in colour, both sexes clothed with fine dark hairs and 
pale yellow deciduous pubescence, cuneus pale at the base ; 
antennze pale, its second joint in the ¢ slightly thickened, 
about twice as long as the third, which again is about 
twice as long as the fourth; in the ? the third joint is 
about two-thirds as long as the second ; the general colour 
of the 9 may be of a uniform orange-brown, or orange-red, 
or the head may be blackish-brown as well as the pronotum 
in front, the scutellum, and a patch on each elytron ; or the 
head, pronotum, and scutellum may be brown, and the corium 
brown posteriorly, the cuneus red, pale at the base; the 
membrane is dusky, with a pale spot below the cuneus ; the 
femora may be red or brown, the tibiz are always whitish, 
with black spines rising from black spots, coxe and tro- 
chanters not pale. 
L. 5? mm. 
Common and generally distributed, on oak, maple, ash, 
and other trees. For a long time I have maintained our 
simillimus as a distinct species, but I believe Dr. Reuter is 
right in sinking it to the rank of a variety; the true 
stiillimus, Kbm., has not yet been found with us. 
P, querctis, Kbim.—Larger than variabilis, and longer 
in the 4d, and the deciduous pubescence coarser and white, 
not golden, second joint of the antenne longer, fourth joint 
about halfas long as the third. General colour less vari- 
able and both sexes more alike, brownish-red, pronotum and 
scutellum sometimes darker; cuneus red, narrowly pale at 
the base; vertex of the ¢ about once and a half, ? about 
twice as wide as each eye; posterior femora longer and
