of the Genus Palmon of Dalman. 257 
the following, published by an anonymous writer in the Entomo- 
logical Magazine, vol. iii. p. 178, ‘ During the winter of 1834 I 
observed in Cephalonia on grass, the asphodel and other plants, 
particularly in marshes, brown ovoid masses resembling the cocoons 
of small moths, and on examining them more closely found that 
they were tough brownish white, composed of layers of scales 
placed with great regularity, and forming cells in series; the cells 
contained a yellowish liquid like the yolk of an egg. Having 
several specimens I detected in one a minute white grub in some 
of its cells: this was in December, 1833. On the 27th of May, 
happening to look at one which lay in my desk, I observed four 
or five minute Chalcide settled on it, and upon opening it to dis- 
cover whether they were the real occupants or intruders, I dis- 
covered several emerging and perfectly formed. They are minute, 
about two lines in length, not including the ovipositor, black, with 
part of the body and the feet reddish, hinder legs variegated and 
thighs thickly incrassated, eyes red, antennz clavate, oviduct ex- 
serted and twice the length of the body. It appeared to make 
fully as much use of its hind legs as of its wings, leaping to a 
considerable distance. In some specimens the oviduct was four 
times the length of the body and recurved. On the 24th May I 
found several young Mantes in the desk, and removing them I 
placed one of the excrescences under a tumbler where it would 
not be disturbed for a few days; several young Mantes oratorie 
made their appearance, which removed all doubts as to the excres- 
cence not being a mass of eggs. The young Mantes devoured 
each other, and the number diminishing I let them out.” 
The short description of the parasites contained in the preced- 
ing account is sufficient at once to point out the generic group to 
which they belong; an elongated exserted ovipositor, incrassated 
hind thighs and clavate antenne, being the characters of the genus 
Palmon of Dalman, founded in the Swedish Transactions for 1825 
upon three species, observed only by that author in gum copal, 
and which were considered by him as intermediate between the 
genera Leucospis and Torymus (Callimome, Spin.) This treatise 
of Dalman las been overlooked by Mr. Walker in his various 
monographs upon this family, in one of which (Entom. Mag. vol. i. 
p- 118) he has evidently described a species of this group from the 
south of France under the name of Priomerus pachymerus, and of 
which a beautiful figure by Mr. Haliday was published in the 
“ Entomologist.” :
