57, 3 Bey-Bienko: Acridiide and Tettigoniid.e from Luzon 385

Pronotum strongly deplanate; the disc practically flat, finely
tuberculate, with indistinct callosities; prozona somewhat broader than long, lateral keels very thin, feebly convergent backward; median keel very fine, not elevated, except the interval
between the transverse sulci where it is very feebly inflated and
indistinctly raised; anterior part of metazona from the hind
transverse sulci with two very distinct, linear, straight carinse,
reaching a little beyond line connecting humeral angles; the
latter distinctly keeled, obtusely angulate; supernumerary keels
well developed, straight, beginning somewhat before shoulder
angles; apical process reaching the apex of hind tibiae, slender.
Posterior angles of lateral lobes not reflexed outward, forming
a sharpened and narrowly rounded angle.
Elytra oval; wings fully developed, reaching the apex of pronotal process.
Anterior and middle femora very slender, long, parallel-sided,
about five times as long as broad, carinae entire. Hind femora
slender; hind metatarsus equal in length to third tarsal joint,
the three pulvilli of the metatarsus equal in length, rectangular.
Coloration uniformly grayish brown.
Length of body, male, 6.7 mm; female, 9.3; pronotum, male,
11.6; female, 12.7; hind femora, male, 4.9; female, 5.3.
This well-characterized species shows distinct affinity to the
Bornean P. angulobus Hancock 5 in the depressed pronotum bearing two abbreviated carnme between humeral angles, in the quite
similar structure of hind tarsi, and in some other features; but
the new species is well separated from P. angulobus by the
broader vertex, strongly narrowed anteriorly; by the distinctly
bicarinate shoulders, not reflexed outward; by the posterior angle
of the lateral lobes; and by some less-important features.
PARATETTIX sp. nov.?
Two males. An extremely graceful species; densely pilose
lower surface of body very narrow; long pronotum with median
keel sharpened and, seen in profile, practically straight, with
spiculate pulvilli on hind tarsus. Probably a new species, but
I hesitate to describe it without a comparison with others belonging to the same group of this genus.
