110 INSECTA. 
Eutornvus, Geoff. Lat.—Entodon, Dalm. 
But from five to eight joints in the antenne; those of the males 
ramous(1). 
In the fifth tribe, that of the Oxrurt, Lat., we observe spe- 
cies similar to the preceding in the absence of nervures in the 
inferior wings, and in which the abdomen of the females is 
terminated by a tubular and conical ovipositor, sometimes in- 
ternal, exertile and protruding through the anus like a sting, 
and sometimes external and forming a sort of tail or terminal 
point. The antenne are composed of from ten to fifteen 
joints, and are either filiform or somewhat largest near the 
end, or clavate in the females. The maxillary palpi of seve- 
ral are long and pendent. 
We reduce the various genera of which it is composed to 
one, the 
Betuy.us, Lat. Fab. 
The habits of these Insects are probably those of the Chalcidiz; 
but as most of them are found on the sand or low plants, I suspect 
that their larve live in the ground. 
Some have brachial cells or nervures in the superior wings. 
Their maxillary palpi are always salient. Their antennz are filiform, 
or simply and gradually enlarge in both sexes. 
Here, they are inserted near the mouth. 
Dryinus, Lat.—Gonatopus, Klig. 
Where the antennz are straight and consist of ten joints in the 
two sexes, the last ones somewhat thicker than the others. The 
thorax is divided into two knots. The anterior tarsi terminate by

Maximilian Spinola, published in the Ann. du Mus. d’Hist. Nat., as well as the 
excellent work of M. Dalman, on the Insects of this tribe.
