Tettigo n ia similis Woodw. Bull. 111 . St. Lab. III., p. 25, 1887. 
Tettigonia hieroglyphica, in ref. from Eastern States (nec Say). 
Smaller than hieroglyphica , which it much resembles, 
pale reddish or grayish green, with several nearly parallel 
lines on the disc of the vertex and a point at apex black. 
Length, 5.5 — 6 mm.; width, 1.25 mm. 
Vertex slightly narrower and more pointed than in hieroglyphica, 
three-eighths wider than its middlelength, over two-thirds the length 
of the pronotum, the margins rounded, apex slightly conical, the 
lateral margin rounding directly to and confluent with the margin 
of the eye. Front and clypeus as seen from side are evenly round- 
ing, the rostrum reaching back to the scutellum. Elytra with the 
nervures somewhat more pronounced than in hieroglyphica , vena- 
tion similar. 
Color; head pale reddish or greenish yellow, apex with a black 
point surrounded by a light circle. Front all light or with a light 
median stripe and numerous short fuscous arcs. Clypeus unmarked 
or with but a minute black point. Vertex with the margins of the 
reflexed portions slightly angularly lined, a line from the angle fol- 
lowing the suture to the ocelli, inside of these on the disc there is a 
pair of loops, their outer limbs often curving around to the ocelli 
and sending a branch back to the posterior margin. These loops 
often reduced in size to feeble lines, and their inner limbs some- 
times broken or wanting. Pronotum with the anterior third light 
yellow, disc olive or brownish, sometimes with a distinct pattern, 
often without definite marking. Scutellum with the median half of 
posterior disc light, margins and anterior disc often clouded with 
fuscous. Elytra grayish green or reddish unicolorous with the nerv- 
ures light, or mottled with creamy yellow, the nervures slightly 
darkened. 
Genitalia; female segment nearly three times the length of the 
penultimate, the posterior margin triangularly produced, whole 
segment transversely convex. Male plates long, triangular, two 
and one-half times as long as the penultimate segment, nearly half 
longer than their combined basal width, their margins fringed with 
hair. 
Specimens have been examined from Maine, New 
Hampshire, Vermont, District of Columbia, New York, 
Ohio, Illinois, Kentucky, Alabama, Iowa, Nebraska, Kan- 
sas, Colorado, Arizona and southern California; and 
besides these, it has been reported from New Jersey {simi- 
lis), and Ottawa, Can. and Massachusetts (as hieroglyphica)-. 
This species has been very generally confused with hiero- 
glyphica and reported under that name. All specimens 
determined as that species that have been received and 
examined from points east of Illinois have proved to
