1878.] 79 [Scudder. 
84. Pezotettix lakinus. Vertex between the rather small 
eyes half as broad again as the basal antennal joints ; foveola broad, 
shallow, flat, expanded in front, the bounding walls low and thick ; 
frontal ridge moderate, slightly expanded at the ocellus, sulcate 
almost throughout, the summit only flat. Pronotum unusually short, 
especially in the 2, but simple, scarcely expanding posteriorly, 
either half of the deflected portion of the anterior lobe slightly 
tumid above in the 3; front margin straight; hind border very little 
angulated and rounded; median carina slight but distinct, equal $ 
lateral carinz well marked, forming a nearly square shoulder, especi- 
ally on the hinder portion of the anterior lobe. Tegmina lanceolate, 
sharply pointed, longer than the pronotum, fully twice as long as 
broad, their inner and costal margins about equally convex. Last 
ventral sexment of the ¢ abdomen conical, strongly upturned, about 
as high as broad, the extreme posterior edge produced to form a 
rather large, rounded elevation, nearly as high as broad; supraanal 
plate triangular, as long as broad, the sides nearly straight, the tip 
rounded; marginal apophyses of the preceding segment rather 
distant, broad at base, with a slight median, tapering, pointed projec- 
tion, the whole process very small; anal cerci very tumid, spherico- 
triangular at base, carinate on the posterior outer margin, with a 
slight, equal, slender and blunt-tipped finger, shorter than the base, 
extending inward and upward from the upper angle of the basal 
swelling. 
The general color is a brownish griseous, tinged below with yel- 
lowish ; the antenne are dark, and sometimes darker apically. Along 
the top of the head and pronotum is a blackish fuscous, rather broad 
median stripe, sometimes broadening in patches, sometimes obsolete ; 
the upper half of the deflected portion of the anterior lobe of the 
pronotum is marked by a broad, blackish fuscous belt, which is often 
separated from the front margin and the frequent extension of the 
band to the eye by a narrow yellow line. The tegmina are uniformly 
griseous, with a median slender line of alternate yellowish and fuscous 
flecks, often obsolete. The hind femora are lighter or darker 
testaceous, with two very broad, oblique, blackish belts, which do 
not reach the pale orange under surface; hind tibiz dull glaucous, 
the spines pale at base, black tipped; sides of the abdomen marked 
with black at base.
