Say’s original description (Coll. Writings, Vol. II, page 256) 
is as folloY7s: 
Head and anterior part of thorax pale, with three transverse lines; 
wings varied with brown and pale; body short, oval; head pale yellowish, 
an elevated, reddish-brown, transverse line between the eyes and before 
the stemmata; front with about nine parallel, equidistant, reddish-brown 
lines, which are interrupted in the middle and abbreviated in the cavity 
of the antenna; antennae placed in a deep cavity, beyond which the seta 
only projects, head beneath black; thorax pale yellowish before, reddish- 
brown and rugose with continuous lines behind, anterior edge elevated, 
reddish-brown, a reddish-brown transverse band on the middle; scutel pale 
reddish-brown; hemelytra varied with fucous and pale, generally forming 
a band on the middle which is more distinct on the costal margin, spot at 
tip and larger one at base; nervules dark-brown; feet black, joint whitish; 
tibiae and tarsi whitish, posterior tibia bi-spinous behind, of which one is 
very robust; length rather more than one-fifth of an inch. 
The band of the hemelytra is sometimes indistinct, three brown dots 
near tip; female generally paler, with the abdomen whitish. 
This species presents a remarkable number of quite distinct 
sub species and varieties, and, owing to the fact that Say’s 
description was of an extreme variety, a great deal of confus- 
ion has existed as to its limits, resulting in quite a number of 
these varieties being described as distinct species. I have 
appended these descriptions and have retained their names for 
the sub-species, except testacea and pini, which I find to be 
simply varieties of a sub-species of which the description of 
osborni is more nearly true ; and it is therefore retained in pref- 
erence. 
The following synopsis of the species is a result of a sum- 
mary of the different descriptions, and the study of 200 speci- 
mens representing every state given below with the exception 
of New Jersey. I am reasonably confident that with the pos- 
sible addition of a few more varieties, it will stand the test of 
any farther discovery of material: 
Large; front broad, fiattish, with about nine bands above; second apical 
cell rectangular, elongate; pronotum finely, sharply wrinkled. 
Front rising gradually from face at sides, making an obtuse angle with 
vertex above, upper portion light with about nine parallel, equidistant, 
transverse, interrupted, brown bands. Vertex very strongly, transversely 
depressed, carinated anterior margin prominent; suture between vertex 
and front distinct; ocelli situated near front margin. 
Pronotum with about nineteen minute distinct wrinkles. Hemelytra 
minutely punctured, with a fine thickly set pubescence; second apical 
cell rectangular, elongate. First, discoid cell curved, narrower than sec- 
ond. Legs stout; spurs, spines and third tarsal segment tipped with black. 
Length, four and one-half mm., width of pronotum, two mm.
