Show 295 inconspicuously enlarged on apical third. Pronotum expanding much, and almost uniformly toward the hinder extremity, the two lobes about equal, the anterior snbcylin-drical, the posterior nearly flat, with rather prominent but perfectly bluut lateral car-iura, the median carina scarcely visible on the posterior lobe, obsolete on the anterior lobe; anterior border minutely notched in the middle; posterior border obtusely angled, the angle rounded; deflected lobes almost longer than broad; mesosternaland metasternal lobes equidistant in both sexes. Tegmina very long and straight, with slight oostai shoulder, the intercalary vein traversing nearly the middle of its area, the axillary uniting at its tip with the auai vein in the basal half of the wing. Hind femora very slender, but scarcely extending beyond the tip of the abdomen; none of the carinas elevated. This genus has the general aspect of Trimerotropis, but differs from it in nearly all its structural features. It has not a few points of resemblance to Hadrotettix, but can hardly be placed near that genus. 46. Anconia Integra, nov. sp.- Apparently greenish yellow in life; apical half of an-teuDie faintly infuscated; head and most of anterior lobe of pronotum smooth, the posterior lobe profusely punotulate. Tegmina rather uniformly flecked with small, obscure, sometimes very obscure, fuscous spots; wings hyaline; the costal margin with a pallid stigma near the middle of the apical half of the wing, some of the veins near the apex infuscated. Hind femora pallid or hoary externally, sometimes with faint pre- median and post- median dusky bands, the edges of the geniculations testaceous ; bind tibiae pale yellow, the apical half of the spines reddish changing to black.
