The thirteen-jointed antenuie in both sexes indicates at once the relationship of Scleroderma to the preceding
genera, which is further shewn by the similarity of the females to that of Pristoeera deprema (pi. XXX,
fig. 4), whilst the five-jointed maxillary palpi, and the minnte basal cells of the wings, at once distinguish it.
There is a great similarity between the females and those of the G-enus Methoca, but the latter have the normal
number (twelve) of joints in the antenn® of the typical aculeate Hymenoptera. There is a considerable number
of species of this genus, as may be seen by my monograph above cited, and by the work of Nees ab Esenbeck,
who has introduced several into his Genus Omalus. Mr. Thwaites has sent me a species from Ceylon, the
female of which has wings. Mr. Haliday took three or four specimens of both sexes of a Scleroderma in a
chamber in which AUagemis PelUo abounded in the mattresses stuffed with husks of Indian corn. He also once
observed a swarm of little ant-like insects (which proved to be Sclerodermie) between the sheets of a bed
made upon a sofa in a house at Lucca, and he suggested the probability that the sofa was stufl^ed with hair
or wool infested by the Attat/emts Peltto.
The Scleroderma Ueolor of Smith, collected in Makassar by Mr. Wallace, is a species of tliis genus, but the
Sci. Modesta, Smith, brought from ' Mysol,'' by Mr. Wallace, belongs to the following Genus Apenesia. Sci.
coniracta, Westw., Trans, liut. Soc. vol. ii. p. 169, from Carolina, in the Koyal Museum of Berlin, is most
probably the female of Pristoeera atra, or an allied species.

The misshaped 4-jointed maxiUary palpi, strong legs, and 13-jointed antennse distinguish the females of
this genus from the wingless females of the allied genera, as well as from the similar aculeated genera.

' Luteo-fulvous, glossy, with the abdomen more chestnut, and each of the segments marked near the hind
margin with a paler indistinct fascia. The head is nearly quadrate, the hind margin nearly straight, the posterior
angles well rounded. The eyes are composed of only six hexagonal facets, forming a black spot on cach side of
the head, near the base of the mandibles; the anterior tarsi have the basal joints curved and dilated, and the
middle tibiie are flattened and spined;' the parts of the mouth are formed as in A. Amazónica.

The large size of the scales at the base of the wings, the minute size of the oral organs, the cornuted head
and neck, and the obsolete character of the veins beyond the middle of the fore wings, give this singular insect
a relationship to some of the Diapriides ; whilst, in other respects, it seems to approach the Cynipid®. The
post costal vein of the fore wings at its apex does not touch the costa, but is deflexed into a branch running
into the disc obliquely.
