Female.—Uniform pea-green or yellowish-green, generally fading to a yellowish 
color in the dried specimens. Legs and beneath paler. Face finely punctured below, 
the rugee above indistinct, frontal sutures conspicuous ; clypeus long, extending for 
half its length beyond the lore; eyes brown. Rostrum yellowish green, tip black. 
Pronotal rugz feeble. Elytra greenish hyaline, rarely very faintly obscured toward 
the apex ; nerves green, pale toward the tip. Wings very delicate whitish hyaline. 
Claws and an annulus ofsmall teeth at the tip of the posterior tibia black. 
Male.—Obscure green or brown; face and scutellum paler; elytra brown, at 
least on the apex and inner margin. Facial punctures and frontal ragz rather more 
distinct than in the female. Scutellum finely and obscurely punctured, Propleura 
with a black spot. Beneath pale yellowish brown or honey-yellow with the venter 
fulvous, in brown examples; or yellowish green with the venter pale, in green 
examples. Tarsi black or more often only tipped with black. Elytra varying from 
pale green with a smoky cloud on the apex and inner margin to uniform deep smoky 
brown. Wings faintly embrowned toward their apex or along their entire outer 
margin ; nervules brown, conspicuous. Tergum greenish or ferruginous, more or 
less invaded with black, or the disk entirely black with the segments narrowly marg- 
ined with pale. 
Length, o', 44—5 mm.; 9, 5—6 mm. 
The individual variation here encountered is considerable and of a 
very puzzling nature, and I do not feel fully satisfied that I have rightly 
defined the species here. Among 86 examples (47 6\' and 39 Q Q), 
now before me, 43 males agree in being of some shade of green or brown 
with the elytra more or less smoky, and with a black spot on the pro- 
pleura ; of the females 37 agree in being of a uniform green of some 
shade with at most but a faint trace of brown at the apex of the elytra, 
and without a black spot on the propleura. I feel confident that the 
variation from green to brown in the males, and from yellowish to deep 
green in the females is not always or entirely dependant on the maturity 
of the indivfdual. Of the six anomalous examples before me three males 
correspond very closely with the females in color, while two females 
mimic the males ; this induced me formerly to consider them distinct 
species, but as the brown males and green females occur together in great 
numbers on the same willow bush both as young and adult, and with 
the entire absence of the similarly colored examples of the opposite sex, 
it seems necessary to unite them although I have not yet found them 
pairing, 
This is by far our most abundant species of Pediops7s in Western 
New York. It lives on Willow and reaches maturity about the 2oth of 
June, continuing abundant until August. I have also taken it at Mus- 
koka Lake. Mr. Uhler records it from Colorado and has sent me an
