54 Mr. Ernest A. Elliott and Mr. Claude Morley on the 
P. Reissigii*® (ii, 89) as both bred by Herr Reissig from 
alder in which this beetle lived, the cocoon he says is 
seven lines in length, clothed with scraps of wood without 
but perfectly smooth within; both sexes of Campoplex 
gracilis '* (11, 81) were also bred from this host by the 
same observer on April 13th and 14th. Further Reissig 
bred several specimens of both sexes of Bracon immutator 
(11, 41) from the pupal nests of this weevil, adding that 
the thick brown cocoons were disposed without order but 
all in close proximity; he also bred several Rogas mar- 
ginator >! (i, 65) from C. lapathi im alder shoots on 
May 4th, as well as a single Braconid resembling R. lim- 
bata, but with the neuration of Brachistes, which escaped ; 
his last parasite of this species was the Proctotrypid, 
Mapria melanocorypha (ii, 144). A single 2 of Zchnewmon 
hassicus* is recorded (lib. cit. 11, 136) from the same beetle 
on April 7th ; cf. Morley, Ichn. Brit. i, 292. We captured 
three 92 Lphialies carbonarius, Christ., flying in the 
vicinity of this beetle’s borings in sallow trees at Tudden- 
ham Fen, in Suffolk, on June 12th, 1900. 
217. Gasterocercus depressirostris, Fab.* 
This beetle—not Rhinocyllus depressirostris, Schh., as 
erroneously given by Marshall (Bracon. d’Europ. 1, 197)— 
was discovered by Radzay in a small live portion of an 
otherwise dead eighty-year-old oak, the bark of which 
was considerably impaired by its borings. With it was 
Spathius Radzayanus (Ichn. d. Forst. ii, 44, footnote) which 
was parasitic, very probably ektoparasitic, upon it, two or 
three apparently attacking each of the somewhat gre- 
garious larvee. The parasitic cocoons are elongate, pale 
rose-red, two and a half lines in length, and two to six 
of them he close together in the excreta beneath bark.

218. Mononychus pseudacort, Fab. 
Fred Smith tells us (Ent. Ann. 1864, p. 114) that Mr. 
Butler has bred a parasite, “apparently belonging to the 
genus Sigalphus,” from this weevil in the capsules of Lis 
fetidissima at Ventnor. 
219. Celiodes quercus, Fab. 
Marshall says (Bracon. d’Europ. i, 492) that Ratzeburg 
bred his Apanteles breviventris trom Celoides quercus in
