The globose or rounded head, which is nevcr flat, oblong, and the difference in the antennæ, the antennæ in males being 10-jointed in the females 13-jointed, readiiy separate the subfamily from the Bethylinæ. The group comes quite close to the Dryininæ, but in the latter the head is transverse or subquadrate, never rounded, while the antennæ are 10-jointed in both sexes.

The genus Olixon, Cameron, originally described as a Braconid, belongs here, without much doubt, I think, judging from the description and the figure. Cameron say" “I am unable to point out the natural position of this curious genus. The elongated fore legs give it a look of a Bethylid, to which, indeed, it bears a general resemblance,; but I feel inclined to regard it as a true Braconid.” I have not seen a specimen of this genus, but Mr. Cameron's figure and description clearly show that it belongs here; the thickened fore femora are characteristic of the group.
