8 Mr. Ernest A. Elliott and Mr. Claude Morley on the 
2. Carabus violaceus, Linn. 
Dr. Ratzeburg says of his Phygadeuon campoplegoides® 
(/.¢. 11, 124): This remarkable little pair came from Herr 
Drewsen, who writes as follows: “Out of TYachina pacta, 
which, as is well known, lives in Carabus violaceus.’ The 
synonymy of this Cryptid is stijl doubtful (cf. Morley, 
Ichn. Brit, 11, 88). 
3. Nebria brevicollis, Fab. 
Van Vollenhoven (Pinae. fol. xxxi) says: ‘Curtis bred 
Proctotrypes (2) viator from the larves of Nebria brevicollis.” 
This refers to the latter’s statement (Farm Insects, 198) 
“that on opening the cells of the specimens of this beetle 
sent to me by Mr. Graham, I found one partly consumed, 
and the other had produced six specimens of Proctotrupes 
vuttor (2): thus showing that this parasite keeps in check 
. . . the larvee of ground beetles.” 
4, Nebria gyllenhali, Sch. 
5. Patrobus assimilis, Chaud. 
In describing Ovesbius castaneus from the top of Garb- 
havel, near Loch Rannoch, the Rev. T. A. Marshall 
(EK. M. M. iii. [1867], p. 194) writes: “This species may be 
suspected of being a parasite of Nebria, Patrobus,” ete. 
N. gyllenhali would be the only British species of the 
genus at that altitude—3,500 feet. 
6. Pterostichus vulgaris, Linn. 
Curtis says the larve of Omaseus melanarius, Il. are 
“frequently infested by a parasite called Proctotrupes 
viator” (Farm Insects, 131). 
7. Gyrinus natator, Scop. 
Mr. F. Bouskell tells us that, in 1894, he bred two or 
three different sorts of parasites from pupe of this beetle 
found by him on reeds at the Cropstone reservoir in 
Leicestershire. “Mr. Parfitt first bred ¢ 2 of his Hemiteles 
gyrint,”® says Morley (Ichn. Brit. ii, 163), “from spring 
pupa-cases, and Bignell also raised it, from pupe of Gyrinus 
natator found by the Rey. J. Hellins upon rushes on the 
banks of the Exeter Canal, of which the latter has allowed 
me to examine both sexes; it is later recorded as bred
