Bufotettix, new genus.
This genus is remarkable for its small size and short legs of the only known species.
Description.—Head barely as broad as the anterior part of the pronotum and furnished above with a few small granules or tubercles, one near the inner margin of each eye and a pair at the base of the fastigium of the vertex being the only ones of noticeable size; fastigium of the vertex horizontal, triangular in shape, and very small, less than half as broad basally as the basal segment of the antenna and not surpassing the antennal scrobae, apically minutely notched and not quite meeting the facial fastigium; eyes globular, very prominent, being unusually protuberant; antennae moderately slender, the basal segment large and furnished with an outer dorsolateral apical tooth, or elongate tubercle; second segment one-half as thick and about one-third as long as the basal one, twice as thick as the succeeding ones, which are cylindrical.
Pronotum rugose, the disk flat and gently constricted mesially, somewhat broader posteriorly than anteriorly, the front margin with a mesial well-elevated tubercle, the hind margin truncate and very little prolonged posteriorly; transverse sulci distinct, especially the posterior one; lateral carinae distinct only on the metanotum; lateral lobes subvertical, almost twice as long as deep, the lower margins straight and horizontal, somewhat thickened, the front angles rectangular, the posterior ones rounded, the posterior margins slanting backward, without distinct humeral sinus; prosternum with a pair of very short blunt spines or tubercles ; meso- and metasternum rectangular, about three times as broad as long, the pits far separated and connected by a deep transverse sulcus.
Abdomen stout; last dorsal segment apically broadly concave ; supraanal plate triangular, longitudinally sulcate dorsally; subgenital plate elongate, apically narrowing and deeply notched, each angle slightly longer than broad and with an apical blunt cylindrical style about three times as long as broad; cerci bluntly conical, scarcely longer than broad, each about as broad as the subgenital plate and simple.
Legs very short, the fore femora shorter than the pronotum and the posterior ones less than twice as long; middle legs missing from the unique type of the only known species; anterior femora unarmed above, beneath armed on the inner margin only with two or three short stout spines on the apical half; fore tibiae flat and unarmed above, beneath armed with a few very small fine spines, extremely minute on the caudal margin, those on the cephalic margin larger and about five in number; posterior femora stout, but little more than twice as long as the greatest width, only about the apical fifth parallel, unarmed above, beneath armed on the outer margin only with six stout triangular spines, the genicular angles unarmed, as are also those of the fore femora ; posterior tibiae armed above on the caudal margin with eight broad-based spines, the last one near the apex, and on the cephalic margin with three very small depressed apically pointed tubercles on the basal half; beneath on the apical half with several very minute spinules on the cephalic margin, the caudal margin with a few still more minute ones near the apex; the hind tibiae are without apical calcars above, the lateral and ventral pairs short.
Tegmina and wings of equal length, barely reaching the tips of the posterior femora and not far surpassing the tip of the abdomen; tegmina about two and one-half times as long as broad, coriaceous, thick and opaque, the radial veins nearly straight, at the base far separated, gradually drawing nearer toward the apex, the posterior one dividing the tegmina into about equal halves; wings equally long as broad, translucid, the veins yellowish; the outer margin evenly rounded, not at all sinuate.
Type, Bufotettix alpha, new species.
