pale yellow. Length, 12.5mm.; width, Bmm. 
Head with eyes but little wider than pionotum, triangular the 
apex rounded. Vertex slightly shorter than its basal width, disc 
sloping, on same plane as pronotum, the surface irregular, a deep 
median furrow, narrow on posterior half and not quite reaching the 
margin, broadening out on anterior half until it is bounded by the car- 
inate margin at the apex. Front gibbous, forming a right angle 
with vertex, clypeus obtusely angled. Pronotum sexangular, round- 
ing in front, the submargin depressed with a few deep pits, disc con- 
vex coarsely pitted; humeral margins long, straight, posterior mar- 
gin rounding with a slight median emargination. Elytra long,

Kentucky, Missouri. It occurs from New York to Illinois

All records for guttata within the United States refer to 
this species. The guttata is a very different looking insect 
scarcely half the size of this species. It belong to the 
genus Tettigonia and has not yet been found north of cen- 
tral Mexico.
