92 HYMENOPTERA FROM SARAWAK. 
tudinally keeled; the front being also bordered below by a 
stout keel. The apex of the pronotum is sharply keeled; 
this keel is continued down the middle of the propleurz ob- - 
liquely, their apex being also keeled. Mesonotum and scutel- 
lum stoutly transversely striated. Scutellar fovea large, 
deep and stoutly keeled in the middle. The metanotum is. 
bordered laterally by a stout keel and outside this, on the. 
pleura, is a stout curved, irregular keel. Radial cellule short, 
the radius curved not reaching half way to the apex; the 
areolet is small, elongate, narrow, closed below by a thick 
pseudo-nervure; the cubitus reaches to the apex of the wing, 
it really issues from the radius, for a transverse cubital nervure 
can hardly be said to exist. The costal, median and submedian 
cellules are all distinct; the externo-median nervure is distinct, 
the discoidal nervure is distinct and reaches close to the apex 
of the wing, it is interstitial with the externo-median ner- 
vure. 
The ovipositor is lone and issues from the base of the 
abdomen, is straight and its sheaths are curved and project; 
the hypopygium is short and does not reach to the apex of the 
abdomen. Legs stout, pilose; the front calcaria are curved, 
the basal joint of all the tarsiis much the longer; the middle 
3 are small; the apical large, but not quite so long as the 
basal one; the claws are large, curved, simple. 
This new genus will form a new subfamily of Cynipide. It 
has the form of Cynips but differs from that in the abdominal 
segments being of almost equal length, and in the straight, not 
curved, ovipositor. The subfamily Lialan@ may be known from 
it by the long, cultriform abdomen, which has, as in our sub- 
family, the ‘segments about equal in length. It has the alar 
nervures better developed than in the other subfamilies and in 
that respect resembles Mesocynips, whose systematic position is 
probably between the /baliing and the Cynipine. 
Mesocynips insignis, Sp.’ Nov. 
Ferruginous-yellow, the yellow tint more noticeable on 
the sides ; the flagellum of the antenne infuscated, paler towards 
the apex ; the mesonotum and the basal half of the scutellum
