132 HYMENOPTERA FROM SARAWAK. 
ately large and are distinctly separated from the base of the 
mandibles; they are slightly emarginate on the inner side. 
Claws pectinated. Disco-cubital nervure originating dis- 
tinctly before the discoidal nervure. Scutellum large, longer 
than broad, distinctly raised and separated. The median and 
submedian cellules in front wings equal in length; there is 
no stump of anervure on the disco-cubital nervure. Meta-thor- 
ax Stoutly longitudinally and transversely striated. Ovipositor 
short. 
In Ashmead’s arrangement (Bull. U.S. Nat. Mus. xxiii, 86) 
this genus would come nearest to the American Thyreodon,- 
which may be known from it by the apex of the clypeus being 
sub-angularly pointed, not broad!y rounded, by the transverse 
median nervure in the hind wings being broken near the top and 
by the disco-cubital nervure being broadly rounded, not sharply 
angled in the middle as in the present genus. ‘The transverse 
median nervure is received very shortly behind the transverse 
basal, almost interstitial with it. The apex of the 3rd abdominal 
segment, on the back, is roundly narrowed towards the base and 
is incised in the centre above.

lower half of the outer orbits, the malar space, the outer edge 
of the mesonotum at the base, the scutellum, post-scutellum, 
the centre of the median segment at the base, its apical half, the 
lower edge of the pronotum, the base and lower edge of the
