and unites at the exterior margin, before the callous point. The first 
joint of the intermediate tarsi is large, and ciliated beneath *.

Where that nervure is straight and unites at the callous point, or 
rather at the branch which commences the cubital cell, The club of 
the antenne is compressed and truncated at the end f.

Distinguished from the preceding by the generally longer antenne, 
which are inserted close to the anterior margin of the head f.

But from five to eight joints in the antenne; those of the males 
ramous §. 
In the fifth tribe, that of the Oxruri, Lat., we observe species simi- 
lar 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 internal, exertile, and protruding 
through the anus like a sting, and sometimes external, and forming a 
sort of tail or terminal point. The antennz 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 several are 
long and pendent. 
We reduce the various genera of which it is composed to one, the 
Betuytus, Lat. Fab. 
The habits of these Insects are probably those of the Chalcidie; 
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 antenne are filiform, or 
simply and gradually enlarge in both sexes. 
Here they are inserted near the mouth. 
Dryinvus, Lat.—Gonartorvs, Aliq., 
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 
two large dentated hooks, one of which is flexed. Some of the fe- 
males are apterous |
