forms a triangular palette; the three last form an abrupt and elon- 
gated club. They are covered with hairs *. 
Evrytoma, I/hq., 
Where the antenne are as if knotted, and furnished with whirls of 
hairs in the males. ‘The ovipositor is short f. 
Misocamre, Lat.—Dir.oueris, Fab., 
Where they are composed, in both sexes, of compact joints and are 
destitute of the whirls of hairs. ‘The ovipositor is long. 
The larva of one species inhabits the gall of the wild Rose tree, 
and devours that of the Cynips, which formed it f. 
In the others the abdomen is flattened above, and either triangular 
and terminated in a long point in the females, or almost cordiform or 
nearly orbicular. ‘The ovipositor is usually concealed, or but slightly 
salient. 
Here the nervure of the superior wings, situated near the margin, 
is always curved, and unites with the callous point at the exterior 
edge. The two posterior legs are the longest. The inner spine of 
the intermediate tibie is small. 
Peritamevs, Lat., 
Where the mandibles are strongly dentated; the club of the antennze 
is short and thick; the abdomen short, cordiform, and not prolonged 
at the extremity, and the scutellum thick and salient §. 
In the two following subgenera the abdomen of the females is pro- 
longed into a conical point. The club of the antenne is narrow and 
elongated. 
Preroma.us, Lat..—Curprtes, Fab., 
Where the thorax is short and not narrowed anteriorly ||. 
CLEonyrmvs, Lat., 
Where it is elongated and narrowed anteriorly. The abdomen is 
also proportionally longer, and the antenne are inserted more infe- 
riorly 4. 
There the nervure of the superior wings, situated near the margin, 
is sometimes straight, and unites at the callous point. The interme- 
diate legs are the longest, and the inner side of their tibiz is furnished 
with a stout spine. . 
The scutellum projects. 
Eupretmus, Dalm., 
Where the infra-costal nervure, as in the preceding Insects, is curved,
