(< xre< pa, vXevpi), nov. gen. Allied to the preceding. Head moderately large, the face vertical; vertex between the eyes rather broader than the lower extremity of the frontal costa; fastigium depressed, with very high and sharp bounding- walls, which are parallel through most of their course, incline slightly toward each other as they disappear posteriorly, and bending sharply in front meet at a right angle: lateral foveola? rather large and distinct, with high walls, the posterior at right angles to the inferior and but little shorter, the other portion of the wall forming a sharply arcuate hypothenuse of the triangle; frontal costa strongly compressed above, expanding to near the ocellus, then parallel, and below the ocellus again expanding, throughout sulcata; eyes of medium size, not very prominent; antenna? ( $ ) slightly depressed, short, scarcely reaching the tip of the pronotum. Pronotum small, slightly constricted in the middle, the posterior slightly longer than the anterior lobe, the dorsum nearly flat, the median carina undivided on the anterior lobe, equal and slight throughout, the lateral carina) similar but strongly arcuate; posterior margin bent at slightly more than a right angle, the angle rounded ; pleura of metathorax with a distinct sharp carina on the outer face, extending from the edge of the coxa? close to the; edge of the closed tegmina. Tegmina extending beyond the tip of the abdomen, the costal area slightly expanded at the end of the basal third, the intercalary and axillary veins as in ( Edooara; wings rather ample. Hind femora moderately slender and short, scarcely reaching the tip of the abdomen, with superior carina unarmed. 35. Stirapleura decumata, nov. sp.- Wood- brown above, paler below; face and mouth Earts tinged with yellow, the former flecked with reddish brown; antennae yellowish rown; behind the eye a broad, dark band, expanding posteriorly, deepening into black above and edged with pallid yellow, extends to the pronotum. Lateral carina? of pronotum a little paler than the disk, especially on the posterior lobe, where a distinct yellowish band follows its interior border, edged on either side by velvety black, followed by reddish brown; more or less of the velvety black follows the inferior edge of the carina? anteriorly and the anterior and posterior borders of the deflected lobes; are distantly dotted with it; bn the anterior section of the deflected lobe next to the lateral carina?, the dark- brown postocellar band continnes; just below it are some abort longitudinal ruga?, and across the middle of the deflected lobe a second dark-brown band extends horizontally and a little arcuate, inclosing just behind the middle a small crescentic yellow, spot. Tegmrna dotted rather profusely, excepting at the extreme tip, with small, unequal, fuscous spots; wings pellucid, most of the veins in the apical half of the expanded wing black. Hind femora, with basal, median, and post- median dark- brown streaks on the upper half of the outer surface of the wing, growing more. oblique apically, and connecting on the upper face with more distinct, triangular, transverse blotches, with darker edges, the inferior outer carina dotted with blackish fuscous; hind tibia? yellow, a little infnscated at extreme tip, the spines black on the apical half. Length of body, 19mm; of antennae, 5.5ram; of pronotum, 3.5mm; of tegmina, 16mm; of hind tibia?, 9.2mm.* 1 $, Southern Colorado, June 11- 20, Lieut. W. L. Carpenter. 30. PhIxboBtromaparvum, nov. sp.- Dull brown; the face infnscated; autenna? pale yellowish brown, a little infnscated at the extreme tip. Pronotum with the same dark markings as in P. pictum Scudd., the posterior margin with the angle a very little less rounded. Tegmina scarcely reaching the tip of the abdomen, pale'cinereous, with four large, equidistant, rounded, triangular, fuscous spots, darkest on the edges, seated upon the ulnar veins, the middle ones larger than the outer; wines hyaline, the veins at the apex blackish. Hind legs as in P. pictum. Length of body, 14.5UU"; of antenme, ( jinni. 0f pronotum, 3.5n, m; of tegmina, 9.5mm ; of hind tibia?, 8. Wmm. 1 <?, plains of Northern New Mexico^ eastern slope, October 14- 31, Lieut. W. L. Carpenter. This species closely resembles the one formerly described under the name of P. pictum, but differs strikingly from it in the shortness of the tegmina and wing, which in P. pictum reach far beyond the tip of the abdomen ; in both, though it is not mentioned in the description of either species, the tegmina have a longitudinal series of equidistant fuscous points just above the radial veins. The genus resembles more closely ( Edaleus Fieb., than Psinidia Stiil, to which I compared it, and, like several genera in its vicinity, but perhaps more than most of them, bears a striking resemblance to the Stenobothri. 37.
