HYMENOFTERA. — PROCTOTRUPID&. El 
the same fruit. I am enabled to give the systematic name of this curi- 
ous insect described by Schmidberger, having received specimens of 
both sexes from him through Messrs. Kollar and Loudon. 
The species of Teleas and its subgenera are parasitic on the eggs 
of other insects, especially in those of Lepidoptera. Zinannius also 
observed one of the species depositing its eggs in the eggs of one 
of the Cimicide (Schrank, No. 761.). M. V. Audouin has also 
reared several minute species of Teleas from the eggs of Penta- 
toma ornatum, as well as from the eggs of Lepidopterous insects. 
The type of this genus is the Ichneumon ovulorum Linn. (Teleas 
Linnei Esenb.), which Linneus and De Geer obtained from the 
eggs of moths. Another species, confounded with the preceding (T. 
ovulorum E’senbeck), was also reared by Goetze and Esenbeck from 
the eggs of moths (Gastropacha castrensis). Bouché observed the 
female deposit an egg in each of the eggs of a brood of Bombyx 
neustria. He describes the larva as elliptical, white, shining, rugose, 
subincurved, and one-third of an inch long (Naturg. Ins. p. 177.). 
Mr. Haliday, regarding the Ichneumon ovulorum Linn. as a My- 
mar, observes upon that group, “ The females oviposit in the eggs of 
other insects, from which the tiny parasite emerges only in the perfect 
state, a single butterfly’s egg often nourishing the transformation of 
many individuals.” (nt. Mag. vol. i. p. 342.) 
A species of the same genus (Teleas truncatus Zs, ii. 288.) was 
reared by Esenbeck from a gall of Cynips Quercis Gemme. The 
same author considers that the Diapriz are parasitic upon the larve 
of the Tipulidze terricole, whilst those of Belyta, Codrus, Cinetus, &c., 
which are often found in fungi in the autumn, are parasitic upon the 
larvee of the Tipulide fungicole ; indeed he reared Proctotrupes par- 
vulus from Boletus circinans, which was much infested by the larve 
of a Mycetophila. (Hym. Mon. vol.ii. p. 316, 353.) 
Mr. Haliday has given a very interesting account of the habits of 
the genus Bethylus, which buries the larvae of some species of Tinea, 
which feed upon the low tufts of Rosa spinosissima, dragging them 
to a considerable distance with great labour and solicitude, and em- 
ploying, in the instance recorded by Mr. Haliday, the bore of a reed 
stuck in the ground instead of an artificial funnel, for the cells which 
should contain the progeny of the Bethylus, with its store of provision.
