The tlii-ee platos, XXIX, XXX, and XXXI, arc devoted to the illustration of a very rare and curions
group of tljinenoptera whose relations "s^dtll other families are very pecnliar. In many respects they approach
nearly to the typical Aculeata, especially to the ]Mutillida?, in the apterous condition of the females, certain of
which closely resemble the females of Methoca ; whilst others resemble some of the smaller Fossores allied
to Psen, &o. Their 13-jointed antennaj in both sexes, ho\vever, at once distinguish them and remove them to
the great aberrant section of the Ilymenoptera. Here they are related, on the one hand, to those genera of
Proctotrupida3, in which the fore wing-s have most of the apical veins in an undeveloped condition, although their
situation is indicated by certain narrow markings on the wings destitute of the fine seta3 with which the other
parts of the wings are clothed. Some of the species, especially those of the Genus Mesitius, are closely allied
to the Chrysididce (which have also 13-jointed antennos in both sexes, and partially obsolete veins in the fore
wings) ; but Chrysis has only 5-jointed maxillary palpi, and the ovipositor is differently constructed. The
Genus Bethylus Latr. (Omalus Jur.) has been restricted to the flat-headed species, which have the hind basal cell
of the fore wings shorter than the front one, and which have 12-jointed antenn;e; whereas in the species before
us those organs are uniforml}^ 13-jointed in both sexes. It is possible that some of the smaller continental
species of Epyris may have been described by Dr. Klug in his Monograph on Bethylus, in which seven species
of the genus are described, in Weber and Mohr's Archiv. (vol. ii. p. 187—). In his generic characters, however,
he describes and figures the maxillary palpi as 6-jointed, and the labial as 4-jointed; and he states that his
species agree in their general chai-acters with Tipkia villom (S. Piez. 235), and Bethjlus mllosus (S. Piez. 236).
The late lamented A. H. Haliday was engaged upon a Memoir on the European Species of the Group,
whilst I was occupied, in conjunction with him, chiefly upon the extra species. My illustrations are therefore
confined to the extra-European species (with the exception of our British species, including Pristocera depressa),
and the species of Mesitius. It is to be hoped that his valuable materials will not be lost to science.
The species are for the most part of small size, although the size of many of them considerably exceeds
that of the great mass of the Proetotrupidie, some of which indeed are the most minute of insects.

This genus was proposed by me for a male insect preserved in gum anime in the Collection of Mr. Strong,
of Long Acre, London. Its characters were consequently not satisfactorily examined. I have recently obtained
a male insect from Port Natal, collected by Ilerr Gneinzius, which I have no hesitation in giving as identical
with the Copal individual, and the British Museum Collection possesses a female which 1 am equally convinced
is the other sex of the same species.
