Show 110 INSECTA. EuLOl'HUS, Geoff. Lat.-Entodon, Dalm. But from five to eight joints in the antennre; those of the males ramous(l). In the fifth tribe, that of the OxruRI, 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 poi~t. The antennre 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 pal pi of seve-ral are long and pendent. We reduce the various genera of which it is composed to one, the BETHYLUS, Lat. Fab. The habits of these Insects are probably those of the Chalcidire; but as most of them are found on the sand or low plants, I suspect that their larvre live in the ground. Some have brachial cells or nervures in the superior wings. Their maxillary pal pi are always salient. Their antennre are filiform, or simply and gradually enlarge in both sexes. Here, they are inserted near the mouth. DRYINus, Lat.-Gonatopus, Kli.ig. Where the antennre are straight and consist of ten joints in the two sexes, the last ones somewhat thicker than the others.
