the orbits of the eyes as high as the base of the antennae, a spot 
on the scutellum and one at each of its anterior angles, sometimes 
absent, the postscutellum, a broad M shaped mark on the median 
segment, the sides of the two basal abdominal segments connecting 
with a transverse band at the apex of the first and with a trans- 
verse spot on each side of the second, and a smaller spot on each 
side of the third and fourth segments yellow. Wings dull fulvo- 
hyaline, almost hyaline at the apex, nervures fusco-ferruginous. 
Length 17—20 mm. 
9. Mandibles falcate, acute. Head nearly twice as broad as 
long, strongly rounded at the posterior angles, with a short, longi- 
tudinal frontal suleus, shining, with a very few scattered large 
punctures between which are elose microscopie punctures. Pronotum 
less than half as broad as the head, shining and sparsely punctured, 
longer than broad, the sides nearly parallel, a very short but deep 
longitudinal suleus on the middle of the anterior margin. Scutellum 
very small and narrow; median segment depressed, subconcave 
with a longitudinal carina, shining and microscopically punctured, 
broadened from the base and as long as the pronotum. Abdomen 
much broader than the thorax, finely punctured, more closely :on 
the first and third than on the apical segments, the apical margin 
of the basal segment slightly raised, with a broad transverse groove 
before it, broadly rounded at the apex and not very narrow at the 
base; the second segment with two transverse carinae in addition 
to the raised apical margin, the anterior carina curving forwards 
towards the sides; pygidium very narrow at the base, truncate 
posteriorly, the surface of the truncation smooth, broadly rounded 
at the apex and with a deep slit at the base. Apical ventral seg- 
ments thinly covered with long hairs. 
Black; the head and legs dull ferruginous; the lateral and 
posterior margins of the head and a broad transverse band between 
the eyes above the base of the antennae pale dull yellow; the 
second abdominal segment and the pygidium more or less fuscous. 
Length 9—10 mm.
