Typophyllum undulatum, new species. (PI. IV, fig. 20.)
This is an inconspicuous form in some respects allied to the species of the genus Mimetica, especially in the posteriorly notched pronotal disk.
Description (female, the male unknown).—Head roughened by small granular tubercles; face flat, the scutellum narrowed above and disappearing between the oppressed apices of the moderately developed and somewhat elevated antennal scrobae; fastigium of the vertex small and triangular, dorsally sulcate, slightly elevated and fitted closely between the antennal scrobae and not nearly attaining their tips; eyes slightly irregularly rounded and very moderately prominent, behind each a slightly elevated colored line representing lateral carinae continuous with those of the pronotum; antennae with the basal segment large, flat above, the second segment considerably smaller and somewhat shorter, the succeeding ones cylindrical, the joints not very conspicuous.
Pronotum slightly concave dorsally, the disk slightly narrower anteriorly than posteriorly, the anterior margin slightly and broadly concave, the posterior margin very broadly angulate and with a small mesial notch; lateral carinae sharp and straight, somewhat roughened by tubercles; lateral lobes nearly quadrate, the lower and anterior margins broadly rounded, the former nearly horizontal, the hind margin straight to the deep but obtuse sinus; prosternum unarmed, meso- and metasterni armed with a pair of short acute spines, the pits merged.
Organs of flight fully developed; tegmina shaped as shown in Plate II, figure 20, and very closely resembling a leaf, there being even a transparent fungus-like spot in the middle of the posterior field; wings very broad apically and rounded, the costal margin considerably curved upward; posterior radial vein stout; ulnar vein branching at about the middle;
legs stout and lobately armed; anterior tibiae wholly unarmed, the foramina conchate, little expanded and not extending above the dorsal surface of the tibiae; middle and hind tibiae unarmed beneath, above furnished with a few apically rounded flattened projections on each margin, the posterior ones with a broad one near the base, no apical spines but with a single pair of ventral cal-cars, short and stout; the middle tibiae are very much broadened in the basal two-thirds; anterior and intermediate femora compressed, about four times as long as broad, unarmed above, beneath armed on the cephalic margin with four very broad, flat, triangular teeth and on the opposite margin with one or two small tubercles; posterior femora not strongly swollen basally, unarmed above, beneath on the cephalic margin with three large flat triangular spines in the distal half and with five or six small ones on the proximal half, the opposite carinae with five or six very small sharp spines in the apical two-thirds, the basal ones very short, mere tubercles in fact; all geniculations unarmed.
Abdomen flattened, the 2, 3 and 7 segments dorsally somewhat lammellately compressed and slightly prolonged posteriorly; supraanal plate slightly broader than long, dorsally roundly convex and apically broadly rounded; subgenital plate a little broader than long, posteriorly narrowed and apically with a broad mesial notch; cerci simple, no more than twice as long as broad, suddenly constricted mesially to less than half the basal width; ovipositor one and one-half times as long as the pronotum, curved strongly upward in the basal third and apically gently enlarged, the upper margin bluntly serrate in a little more than the apical half, the serration of the apical fourth or fifth larger and forming a double row; the lower margin is tuberculously serrate in the apical half, the teeth larger apically and covering also the lateral surfaces of the lower valves.
Measurements.—Length: pronotum, 6 mm.; anterior femora, 6 mm.; posterior femora, 16 mm.; tegmina, 35 mm.; wings, 25 mm.; ovipositor, 9.5 mm. Width : pronotum posteriorly, 5 mm.; tegmina mesially, 17 mm.; posterior femora at widest point, 2.5 mm.; ovipositor mesially, 1 mm.
