Having received specimens of this interesting little insect from M. Victor Audouin himself, I am able to 
point out its real generic position, and also to state its want of identity with the insect to which it was referred 
by its discoverer and others. In his plate he incorrectly represents the antennz as fourteen-jointed, but in his text 
he describes them correctly as thirteen-jointed, but as ‘coudées,’ which is not the case. In the spring of 1838, 
M. V. Audouin observed numbers of specimens running about very quickly on the young shoots of vines in the 
‘Maconnais,’ which were already infested with the young larve of the destructive Zortrix (or Pyralis) Vitana, 
which were often seized and killed by the winged Goniozus. He subsequently, in the month of July, discovered 
the history of the parasite, having found a larva of the Zortriw covered with eight small apodal larve of a deli- 
eate green colour, and of the size of a large pin’s head; each of these little parasites had its head immersed 
between the segments of the body of the larva. M. Audouin has given very careful details of the structure and 
economy of these little parasite larve, which at the end of six days had completely changed both their form 
and colour ; the whole of the anterior part of their bodies had penetrated into the body of their victim, which 
had become much contracted, whilst they had assumed an oblong form and become brightish yellow in colour. 
In two days more they had become darker coloured with whitish spots, with a brown blotch at the extremity of 
their bodies. On the 2nd of August, all these larve, having quitted the shrivelled body of the caterpillar of 
the Tortria, commenced spinning a small cocoon of dirty-white silk, in the interior of which they were trans- 
formed to pupe. In a fortnight’s time the parasitic insects appeared in their perfect state. The cocoons are 
generally fixed to the leaves, being attached to each other by a brown layer of silk. They are marked at one 
end with a black spot, which is in fact the cast skin of the larva. The details of this history are illustrated by 
Audouin in his pl. XX, figs. 4-16.

Habitat; Adelaide, Australasia. In Mus. Hopeiano Oxoniz. 
Genus—SCLERODERMA. 
The characters of this genus, founded only on female specimens, were first detailed in my monograph of 
the group published in the second volume of the Transactions of the Entomological Society, with figures of the 
generic details!. Up to the present time no description of the male characters of the group has been published, 
but I am now able, by the researches of Mr. Haliday in Italy, and Sir S. 8. Saunders in Albania and Corfu, to 
complete the diagnosis of the genus. 
Corpus elongatum gracile leve, maris alatum, femina apterum; caput magnum subquadratum supra 
convexum, foemine oculis parvis, ocellis obsoletis ; antenne breviuscule in utroque sexu 18-articulate (fig. 13 a, 
1 Tn the text of this memoir, vol. ii. p. 1-6, the antennz were inadvertently described as ‘ ro-articulate,’ instead of 
13-jointed as they are in reality, and as shewn in my figures, pl. XV, fig. 10 a, representing both antenne of Sel. znter- 
media, and fig. 11 6, the antenna of Sel. contracta.
