d. Forst. ii, 128); and Ratzeburg obtained a couple of 
Alysia rubriceps,* 2 2 (1. ¢. i, 56) from fir logs infested by 
the same beetle. 
234. Magdalis violacea, Linn. 
Several specimens of Chelonus atriceps were bred by 
Ratzeburg (Ichn. d. Forst. i. 43) from spruce infested with 
Magdalis violacea in the Frankenwald; Glypta concolor 
(i, 121) was also bred with this beetle, out of fir billets, 
as were several Lurytoma abieticola (i, 174) from fir logs; 
several 22 Pteromalus violaceus (i, 208) emerged from fir 
billets from the Hartz, in which this beetle had bored ; 
and several Spathius brevicaudis (1, 49) from fir wood in- 
fested with Cureulio violaceus. Brachistes rugosus * (ii, 
28 et ii, 29) was bred by both Nordlinger from young dry 
fir, and Ratzeburg from blocks of wood, in which C. violacea 
was living; many f2 of Pteromalus virescens *” (11, 204) 
were also bred by the former, and Opius rubriceps 76+ (il 
66) by the latter, from this weevil. 
235. Rhopalomesites tardyi, Curt. 
Under Odontomerus dentipes, Gmel., in his private copy 
of the 1872 Catalogue of British Hymenoptera, Marshall 
has entered a MS. note: “taken by Bignell, Aug. 6, 
entering burrows of Mesites tardit.” 
236. Eremotes strangulatus, Perr,* 
Exothecus rhyncoli, Gir., is said by Dr. Laboulbéne (Ann. 
Soc. Fr. 1877, p. 414) to have been bred from this species 
by Perris. 
237. Scolytus. 
Brischke records Pachychirus quadrum *8 from Eecopto- 
gaster sp., and Giraud, Hxothecus lanceolator,4’ Nees, from 
Scolytus sp.; Brachistes longicaudis®° was bred from an 
unspecified individual by Ratzeburg (Ichn. d. Forst. i, 23), 
and Kirchner (Cat. 118, probably quoting (id. cit. iii, 27) 
gives Sigalphus flavipalpis,®® Wesm., “ Hohenheim. Gez. 
aus Hecoptogaster-Arten.” 
238. Scolytus destructor, Oliv. 
From Lecoptogaster scolytus some interesting parasites 
have been recorded by Ratzeburg, who received several $ 3
