Loja subulata, new species. (PI. I, fig. 10; PI. II, fig. 12.)
This is a much more robust species than laevis Giglio-Tos, the only other species known. The fastigium of the vertex is less pointed than in that species and the stridulating vein of the left tegmina is less angularly projected than in the case of laevis as illustrated by Karny in Wytsman's Gen. Insectorum, Fasc. 141, plate iv, fig. 10 (1912).
Description (male and female).—Head moderate, no broader than the pronotum; fastigium of the vertex about as broad as the basal segment of the antenna, the sides about parallel, distally converging very slightly, the tip broadly rounded, the whole not exceeding the basal segment of the antenna in length, evenly rounded dorsally and beneath convergently contiguous with the facial scutellum.
Pronotum subtruncate anteriorly and posteriorly, but little produced behind, the disk nearly flat and merging into the lateral lobes with persistent but rounded lateral carinae which diverge very gently at both extremes; lateral lobes much longer than high with rounded angles and very obscure humeral sinus, the lower margin descending posteriorly, the deepest portion behind the middle; prosternum armed with a pair of long spines.
Legs moderately stout; fore coxae armed with a long sharp spine; fore tibiae with conchate foramina on both sides, unarmed above but armed beneath, as are also the middle ones, with several pairs of medium fixed spines; hind tibiae armed on both margins above and below, with an apical spine above next the apical calcar on the inner side only; fore and middle femora armed beneath on the cephalic margin only with short stout spines, two on the anterior and three on the middle ones; hind femora strongly swollen in the basal half, armed beneath on both margins with short stout spines, three or four on the inner and four or five on the outer; geniculations of all the femora acutely angulate, those on the inner side of the middle ones and on both sides of the hind ones being spinose.
Tegmina but little longer than the pronotum and about half as broad as long, apically broadly rounded, especially in the male; stridulating vein of the left tympanum of the male very thick but not angularly projecting beyond the anal margin. Plate I, figure 10, shows the shape of the tegmina of the male; wings abortive, forming mere padlike projections.
Abdomen with the anal segment of both sexes deeply cleft apically, each angle forming a tapering spinelike process; subgenital plate of male triangularly notched apically and furnished with a pair of stout cylindrical apically rounded styles about three times as long as thick, of the female triangular in shape and apically entire, or gently concave; cerci of male short, stout, somewhat compressed, twisted inward and downward apically and with an apical chitinized point, of female simple, round and tapering to a point, the whole about four times as long as basal width and gently curved inward; ovipositor somewhat longer than the pronotum and shaped as in Plate II, figure 12.
General color green, in cabinet specimens yellowish green; the extreme tips of the tibiae, a spot at the lower end of the foramina of the anterior tibiae, the apex of the mandibles, and the lateral carinae of the pronotum, especially the ends, black; the eyes are blackish and the anal margin of the elytra and the tympanum of the male are marked with blackish; none of the above-mentioned black markings are conspicuous, those of the pronotum and the tegmina of the male being the most noticeable; the spines of the legs are mostly tipped with dusky and the femora all have distinct and quite noticeable piceous spots at the base of each ventral spine; the fastigium of the vertex and the basal segment of the antennae are slightly brownish and at the vertex of the facial scutellum is a slightly elongate yellowish ocellar spot; the elytra of the male also has a few small but noticeable black spots about the middle.
Measurements.—Length: pronotum, male and female, 6 mm.; tegmina, male, 11 mm., female, 7.5 mm.; posterior femora, male, 14 mm., female, 15 mm.; ovipositor, 10 mm.; width: pronotum at posterior margin, male and female, 4 mm.; ovipositor at widest point, 2.5 mm.
