not conspicuous, but separated from that of vertex. Antennae very
long; first joint small, cylindrical, about 1.5 times as long as
wide. Maxillary pa1pi very slender; apical joint narrower than the
precedings, slightly curved, cylindrical but very slightly swollen
at the tip, at where it is truncated, a little longer than 2 precedings
together.

gradually broadened behind, with the front margin straight and hind
margin moderate1y convex. Intermediate and hind sulci distinct,
the former being V-shaped and the later nearly straight. Lateral
lobes as long as broad, the front margin straight and very slightly
oblique, lower margin strongly convex and hind margin S-like curved.
Mesosternal lobes rounded, a little longer than broad; metasternal
lobes semicircular.
Abdomen short. Subgenital plate
of male moderate1y long, the narrowed portion rather short and provided
with 3 distinct carinae, of which the median one is narrow and low,
the apex triangularily incised, the apical lobes being pointed and
provided with a conspicuous but rather short stylus; of female short,
trapezoidal. Supra-anal plate semicircular. Cerci of male moderately
long, granulate, curved inwards, conspicuously sharpened apically,
provided with a long sharp spine at the middle of upper side. Ovipositor
as long as front tibia, strongly compressed and moderately curved
above, rather regularly crenulate on both the surface and margins
