Show 283 oing from the middle of the vertex between the eye? along their upper edge, but separate from it; eyes moderately large and prominent, the front edge nearly straight in the female ; vertex between the eyes broader than the middle of the frontal costa in the 9, of about equal breadth in the <?; fastigium broadly and shallowly channeled, most deeply in the <?, with distinct, and nearly straight lateral carinas, which melt iu to the edge of the frontal costa, the latter distantly punctate throughout, slightly narrowed, and scarcely convex at its upper extremity, broadening slightly at the ocellus, which is sunken, and followed beneath by a slight, short sulcation ; antennre uniform brownish yellow. Pronotum above with the posterior lobe nearly flat, the anterior faintly con- - vex, the whole broadening slightly behind, especially iu the female, the posterior border convex, with somewhat straight sides, so as to appear almost angnlated ; median carina very distinct, though slight on the posterior lobe, but faint on the anterior lobe, and scarcely elevated except at the extreme front; lateral carinas distinct, except anteriorly, but obtuse, the deflected lobes descending vertically; both dorsal and deflected lobes of the color of the head, the posterior lobe a little clearer above and the lower part of the deflected lobes a little paler; upper third or more of the deflected lobes with a dark reddish brown, fuliginous, or blackish stripe extending from the posterior aniens forward to the eye, narrower on the head, and there margined above with a yellowish line; transverse sulcations distinct, occasionally marked above with black; prosteraal spine stout, conical, very blunt at apex. Tegmina less than half as long as the abdomen, subfusiform, the tip roundly pointed ; they are dark brown, obscured, clouded, and dotted with black, most of the veins dark castaneous; wings a little shorter than the tegmina. Hind femora dull brownish yellow, the outer and upper faces with two submedian, rather broad, oblique, and angnlate blackish fuscous stripes, besides a basal and an apical cloud of the same; bind tibia? of a warmer yellow, the apical half of the spines. black; arolium of same legs yellow, margined with blackish, broad obovate, as long as the breadth of the apex of the hind tibiae (<? ), or obpyriform, as long as the claw and as broad as the apex of the last tarsal joint ( 9 )• Abdomen yellow, heavily mottled above with dark reddish brown, deepening laterally into black at the bases of the segments; last abdominal segment of male terminating in a blunted point; anal cerci of male as long as the width of the hind femoral geuicular lobes, slender, straight, tapering on the basal half, the tip bluntly rounded* Length of body, < J, 17mm; 9, 2T » rnm : of antennae, <?, 6.5m, u; $, 7.5, nm; of tegmina, a, <?, 5.5mn » ; 9 , 7.75""°; 6, <?, 6.5mm; 9 * 9.7, n*; of hind tibi ® , $, 7mm; 9, 9ram. 4 £> & 9> 4 immature, Taos Peak, Saugre de Cristo Mountains, Northern New Mexico, at a height of 13,000 feet, Lieut.

Marshallii Thorn., with some doubt, and therefore have described it anew. Specimens from Taos Peak and Southern Colorado seem to differ only in the length of the tegmina, those marked a iu the table of measurements coming from Taos Peak and those marked b from Southern Colorado. A single specimen from Northern New Mexico ( 9 ) agrees wholly in this respect with one from Taos Peak. 13. Pezotettix stupefactut, nov. sp.- Head light brown or yellowish brown, the upper half and sometimes the whole head mottled rather heavily, on the top of the head very heavily, with brownish fuscous, often becoming blackish in a median band on the top of the head, and, less distinctly, above the upper edges of the eyes, as in P. Marshallii ; eyes, particularly of the male, large, the front border nearly straight in the female; vertex between the eyes broader than the middle of the frontal costa in the female, narrower than it in ( he male; fastigium distinctly channeled, most deeply in the male, with distinct and nearly straight lateral carina), which run into the outer edges of the frontal costa; the latter distinctly punctate near the edges like the whole of the face, nearly equal, but slightly narrower above, the surface flat, with a slight, short, narrow sulcation, in the upper part of which the ocellus is situated; antennae brownish yellow, becoming dusky toward the tips. Pronotum above nearly flat, the anterior lobe with scarcely perceptible fullness, and on either side of the median carina, at the posterior sulcus, a slight oblique depression; the whole pronotum broadens a little and rogularly in passing backward, the posterior margin obtusely and roundly angulated; median* carina distinct though slight on the posterior lobe, inconspicuous, excepting in front on the anterior lobe, and in the female nearly obsolete; lateral carina? distinct, though not prominent; surface of pronotum profusely punctate, almost rugnlose behind. Pronotum brownish yellow, darkest on dorsum ana profusely flecked with darker colors; upper third or half of deflected lobes with a brownish fuliginous belt extending from the last transverse sulcus to the eye, narrower at the extreme front of the pronotum and on the head ; transverse sulcations distinct, only seldom, and then but slightly, marked with black *. prosteraal spine short, stout, bluntly conical, in the male thickened apically. Tegmina fully half as long as the abdomen, elongate, subfusiform, in the male almost linear, the tip roundly pointed, dark brown, more or less variegated with yellowish and blackish, the small spots showing a tendency to a longitudinal arrangement; most of the veins light; wings a little shorter than the tegmina.
