Tegmina about as long as the pronotum, slender, short, lanceolate; wings rudimentary. Hind femora slender, yellow, tinged on upper half with brownish and obscurely, narrowly, and transversely bifasciate above with the same; hind tibia) glaucous (?), the spiues reddish, tipped with black; arolium extremely large. Abdomen yellowish, tinged above with greenish brown, the last segment of the male scarcely upturned, terminating in a blunt }) oint; anal cerci of male depressed laminate, scarcely longer than the sides of the ast dorsal segment, gently incurved, tapering ou the basaT half, scarcely enlarging beyond, the tip broadly rounded. Length of body, 18.5mm; of antenna), 9.5mni; of pronotum, 4.25n, m ; of tegmina, 4.15mm ; of hind tibia), 9mm. 1 <£, Plains of Northern New Mexico, eastern slope, October 14- 31, Lieut. W. L. Carpenter. 22. Pezotettix jucundus, nov. 6p.- Yellow, marked with brownish fuscous; top of the head behind the narrowest part of the vertex a little tumid, marked with an elongated, triangnlar, blackish fuscous dash, through the middle of which runs a yellow line, and » by a supraorbital arcuate band of a similar color usually broken and terminating just below a narrow, short, yellow stripe behind the upper part of the eye; vertex between the eyes rather narrower than the frontal costa, the fastigium broadening more than usual in front of the eyes, and longitudinally, broadly sulcate throughout; frontal costa broad and nearly equal, broadest just above the ocellus, rather sparsely punctate, and at the ocellus very shallowly Bulcate, often nearly imperceptible. Pronotum short and rather stout, the anterior and posterior halves of the deflected lobes nearly symmetrical ; dorsum with equal sides, the posterior lobe scarcely more than half as long as the anterior, the former divided in the middle by a straight sulcus, extending only just beyond the lateral carina), and immediately behiud this, one- third the distance only to the posterior sulcus, by the sinuate sulcus, which passes across the deflected lobes; the whole anterior lobe slightly gibbous, particularly in the female; the median carina, which is marked with dark brown and is distinct, though slight, on the posterior lobe, is here obsolete, represented only by the dark line, sometimes faintly impressed; the lateral carina) are very obscure, converging anteriorly, and distinguished by a narrow, dull, yellow stripe, the rest of the dorsum and the upper part of the deflected lobes being obscurely marked with dusky brown, which, on the deflected lobes, is darkest in the sulci; a distinct longitudinal sulcus, more distinct for its deeper color, unites the two percurrent sulci of the deflected lobe in the middle; anterior border marked by a submarginal continuous sulcus, distinct only on the sides; posterior border very broadly rounded or 6ubangulated; prosternal spine straight, rather slender, subcorneal, bluntly pointed. Tegmina subovate, slightly longer than the pronotum, the apex roundly angulated, the veins mostly of a light color, the middle field furnished with three or four small, quadrate, dark spots in a longitudinal row; wings rudimentary; pleura with an oblique bright- vellow stripe edged with black above the hind coxa?. Outer disk of hind femora marked within the carina) by a large, apical, yellowish- brown spot, a very broad, angulate, transverse, median band of the same, and a similar basal band, sometimes obsolete or obsolescent, on the lower half; outer arc of genicular lobes black; tibia) yellow, the apical half of the spines black; arolium either quadrate, rather narrow, longer than the claws (<£ ), or obpyriform, small, but little more than half as long as the claws ( 9 ). Abdomen yellow, the sides chafed by the femora dark fuscous; the joints of the abdomen of the female are less compressed than usual, and also contracted, and, the appendages being short, it has a peculiarly compact appearance; joints of the male abdomen normal, the last joint upturned, the apex rounded and entire; anal cerci of male very broadly expanded at the base, tapering rapidly and regularly just beyond the middle, beyond less rapidly, forming a delicate, slender, but bluntly pointed tip, slightly hooked downward. Length of body, $, 15.5rom; 9,17* m; of antennae, <?, 6.75mm ; 9, 6mm; of pronotum, <? , 4.1u, m; 9 ,4.75ram ; of tegniina, <?, 4mm ; 9 , 5.1mm ; of hind tibia), <? , 9.25mm; 9 , 10mm. This species is described from 11 $, 10 9 , collected by Dr. Edw. Palmer at San Diego, Aguas Calientes and Tighes Station in Southern California. A male and female in not so good coudition, taken by Dr. O. Loew, near Mojave River in July, No. 870, are larger than the average ( $ , 19.5mm; 9 » 18.5mm), and have proportionally longer tegmina (&, 6.5rtmi; 9> 6ram). Especially is this the case with the male; agreeing, however, in all other respects, and having identical anal cerci, there can be little doubt that they belong to tnis species. 23. Pezotettix enigma, nov. sp.- Pale brownish yellow, marked with darker brown and fuscous. Head large, tumid, all the angles rounded, the summit darker, with a sometimes inconspicuous median black ink stripe, broadening from in front backward ; vertex between the eyes narrower than (<£ ) or equal to ( 9 ) the frontal costa; fastigium |
