This species resembles and is allied to P. flabellatus, described 
above. 
89. Pezotettix aridus. Vertex between the eyes narrow, 
being rather less than the width of the first antennal joint; foveola 
suleate, narrow, considerably expanding in front, the bounding walls 
stout, rounded; frontal ridge moderate, nearly equal, contracted 
slightly just below the ocellus, above flat, below the ocellus a little 
suleate. Pronotum simple, expanding a very little posteriorly, the 
anterior lobe slightly swollen on the deflected lobes above; front 
margin straight, hind margin gently convex, subangulated; median 
carina distinct, equal, but low and rounded; lateral carinz wholly 
obsolete, excepting on the front portion of the posterior lobe, where 
they are very slight; posterior lobe punctate; anterior lobe faintly 
and very distantly subpunctate. Tegmina rounded ovate, shorter 
than the pronotum, hardly more than half as long again as broad ; 
costal and inner margins about equally convex, the extremity excised 
and broadly rounded, not in the least produced. Last ventral seg- 
ment of the ¢ abdomen .subpyramidal, broader than high, the 
extremity broadly rounded, but subcompressed, the apical edge not 
produced, entire; supraanal plate triangular, about equally long and 
broad, the sides nearly straight, the tip angulated ; marginal apophyses _ 
of the preceding segment consisting of a pair of subapproximate, slight 
and equal fingers, bluntly tipped, hardly more than a quarter the 
length of the supraanal plate ; anal cerci slender, compressed, slightly 
and very broadly concave on either side, directed backward and a 
little inward, the upper portion of the enlarged extremity produced 
considerably, and curved over still more inward, tapering and bluntly 
rounded at tip; the whole is considerably shorter than the supraanal 
plate. 
The specimens before me have lost their colors from immersion in 
alcohol, but they were apparently light colored, probably more or less 
flavous, and for the most conspicuous markings have a broad, black 
band at the upper limit of the deflected lobes of the pronotum, which 
extends only faintly over the back of the head to the eye; this band 
either narrows on the posterior lobe, so as only to edge the lower side 
of the lateral carinz, or, if of equal width with the preceding portion, 
is enlivened by a yellow stripe passing longitudinally through the
