shorter, with shorter antenna, the abdomen especially shorter and less inflexile.

Having received specimens of this interesting little insect from M. Victor Audonin 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 antenna; as fourtcen-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
' Maçonnais,' which were already infested with the young larvoe of the destructive Tortrix (or Tyralis) Vitana,
which were often seized and killed by the winged Goniozus. He subsequently, in the month of July, discovered
the histoiy of the parasite, having found a larva of the Tortrix covered mt h eight small apodal larva; of a delicate
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 larvoe, 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 peneti-ated into the body of their victim, which
had become much contracted, whilst they had assumed an oblong form and become brightish yellow in colour.
I n 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 larvoe, having quitted the shrivelled body of the caterpillar of
the Tortrix, commenced spinning a small cocoon of dirty-white sük, in the interior of which they were transformed
to pupie. 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 pi. XX, figs. 4-16.

GENUS—S CLERODERMA.
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 d e t a i l s U p 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. S. Saunders in Albania and Corfu, to
complete the diagnosis of the genus.

^ In the text of this memoir, vol. ii. p. i-6, the antennje were inadvertently described as ' lo-articulatse,' instead of
13-jointed as they are in reality, and as shewn in my figures, pi. XV, fig. 10 a, representing both antennae oi Scl. intermedia,
