speckled with blackish fuscous dots, which generally cluster more or 
less into two very oblique bands in the middle and beyond the mid- 
dle, and also margin interruptedly the upper outer carina; hind tibize 
red, the apical half of the spines black.

86. Pezotettix discolor. Vertex between the eyes half as 
broad again as the basal antennal joint (¢ ¢), the foveola shallow, 
indistinct, broad, enlarging apically; frontal ridge broad, equal, flat 
(2) or slightly tumid (2) above, sulcate below. Pronotum simple, 
scarcely enlarging on the posterior lobe, front border straight, hind 
border roundly and broadly angulated; median carina distinct 
though rather slight, equal; lateral carine scarcely perceptible; pos- 
terior lobe of pronotum faintly punctate. Tegmina tapering, a little 
longer than head and prothorax together; the anterior and posterior 
fields separated by an angle. Last ventral segment of ¢ abdomen 
conical, longer than broad, the tip compressed; supraanal plate tri- 
angular, longer than broad, pointed, the sides straight; marginal 
apophyses of the preceding segment consisting of a pair of approxi-. 
mated, small, triangular teeth, the tip a little produced; anal cerci 
forming on each side a broad semicircular rounded flap, the upper 
side concave, the lower convex, the tip rounded, the whole in one 
plane. 
The general color is a yellowish er cinereous brown above, a paler 
brownish yellow below, marked on the sides of the head, prothorax 
and pleura as in P. texanus. The antenne are pale red, infuscated 
apically. The superior field of the tegmina is of the same color as 
the disc of the pronotum, or occasionally a little paler, while the de- 
flected field is nearly always much darker brown, the middle field 
marked by dashes of blackish fuscous which occasionally suffuses 
nearly the whole of the deflected pertion. The hind femora are 
twice barred with blackish above, and have more or less blackish fus- 
cous on their outer face; while the under portion of the femora is 
- yellowish and the hind tibie red with black-tipped spines.
