Hoplotettix, new genus.
This is apparently most nearly allied to Nannotettix but the armed basal segment of the antennae and spined geniculations of the femora will serve to separate it readily from that genus.
Description.—Head of moderate size, no broader than the pronotum; fastigium of the vertex elongate triangular, twice as long as broad, apically pointed, dorsally sulcate, not quite reaching the tips of the antennal scrobae and with a pair of moderately elevated basal tubercles; eyes round and prominent; basal segment of the antennas armed apically on the inner side with a stout spine. Pronotum rugose with a scattering of little-elevated rounded tubercles, the disk rounded into the lateral lobes without lateral carinae except dull ones on the posterior three-fourths of the metazona; the pronotal disk is subtruncate posteriorly, the disk there flattened and with a short slight median carina, and very broadly and roundly angulate anteriorly and usually with a slight mesial swelling on the front margin; transverse sulci well developed, the posterior one very distinct; lateral lobes shallow, about twice as long as high and without humeral sinus, the lower margin thickened and straight, gently slanting upward from in front backward; prosternum with a pair of moderately long spines; meso- and metasternal lobes acutangulate, the latter more rounded; metasternal pits merged to form a single rounded opening. Organs of flight strongly abbreviated, the elytra scarcely twice as long as the pronotum and the wings scarcely longer. Legs long and slender, the anterior femora nearly twice as long as the pronotum; anterior tibiae flat and unarmed above, beneath armed on both sides with several spines; foramina conchate, little expanded; middle tibiae unarmed above on the cephalic margin, the opposite margin armed with from one to three short spines and armed beneath on both sides with several spines; posterior tibiae armed above and below on both margins for most the length, an apical spine above on both sides ; all femora unarmed above but with all the geniculations spined; anterior and intermediate femora unarmed beneath on the caudal margin, the opposite side with one or two spines; posterior femora armed beneath on the outer, or cephalic, margin only with six to eight spines in the apical two-thirds. Abdomen stout, subcompressed; subgenital plate of the male apically narrowed, deeply cleft, the side pieces cylindrical, about twice as long as broad and terminated by a pair of cylindrical blunt styles about four times as long as broad, of the female apically narrowed and with a V-shaped notch; supraanal plate of both sexes about as long as broad, apically broadly rounded, more so in the male, where it is turned down to a vertical position; cerci of male cylindrical, simple, about four times as long as broad, apically suddenly constricted to a sharp naked inwardly directed spine; ovipositor short and stout, moderately curved upward and gradually tapered to a sharp point, the whole about twice as long as the pronotum and unarmed above and below, the ventral margin apically very minutely undulate.
