Hymenopterous genus Scleroderma. 127 
subsequently described the insect, raising it into a 
separate genus, Holopédina. He also had found the 
winged males and both conditions of the females. He 
states :—‘‘ Ich habe diese Art aus einem Polyporus der 
an einem noch lebenden Hichen stamm sass, erzogen ; 
und zwar in beiden Geschlechtern, die $ waren viel seltner 
als die @ und unter den letztern die geflugelten Indi- 
viduen haufiger als die ungeflugelten.”” Both H. Foerster 
and myself failed to notice any connection of these little 
insects with any other resident of the Fungus on which 
they might be parasites. 
I subsequently obtained specimens of both sexes from 
the late Mr. Raddon, who had found them in Indian 
corn received from Africa. 
The male insect is represented in Plate VI., fig. 1, 
the winged female in fig. 2 and the wingless female in 
fig. 8, the antenna of the female in fig. 2a, and the base 
of the fore wings in both sexes in fig. 2). In the 
wingless female represented in the woodcut accompanying 
my original description the base of the abdomen had 
been compressed, distorting the basal segment and giving 
it the appearance of a peduncular scale like that of an 
ant, whence the specific name which I applied to the 
species. Fig. 4a represents the head of the male of the 
Indian corn specimens, and 4b the base of the fore wings 
of the same.

I am indebted to Mr. Staniforth Green, of Colombo, 
Ceylon, for the two very minute insects described above 
too concisely, being prevented from giving a fuller 
description in consequence of the specimens being 
mounted in Canada balsam as microscopical slides.
