40 Mr. Ernest A. Elliott and Mr. Claude Morley on the 
Hallomeni affinis, in Boleto fomentario habitante, mense 
Juni.” This is quoted by Kirchner; and Ratzeburg 
(Ichn. d. Forst. i, 86) says under Porizon moderator that 
Herr Wissmann has bred it from Hallomenus affinis in a 
fungus on beech at Miinden, in Hanover. 
150. Melandrya caraboides, Linn. 
Laboulbene gives (Ann. Soc. Fr. 1877, p. 412) Aspigonus 
diversicornis,»’ Gir., as having been bred by Perris from 
this species; and Ratzeburg (Ichn. d. Forst. iii, 69) says 
Nordlinger found Helcon claviventris in the trunk of an 
ancient beech tree in company with it, adding Mesostenus 
ater as an alternative parasite ; the latter, however, emerged 
from wood containing unspecified Melandrya, Sphex and 
Dasytes (q. v. ante). 
151. Mordellistena episternalis, Muls.* 
From this beetle, Giraud tells us (Ann. Soc. Fr. 1877, 
p- 426) that M. Perris bred the Chalcid, Hurytoma 
histrionica, Forst. 
152. Metxcus paradoxus, Linn. 
It may be well to indicate that the Tryphonid, Spheco- 
phaga vesparum, Curt., though often found in the same 
nests of Vespa vulgaris as this anomalous beetle (ef. 
Morley, E. M. M. 1900, p. 123), is now considered to prey 
exclusively upon the larvee of their common host, in spite 
of Hope’s assumption that S. vesparwm was parasitic upon 
M. paradoxus (Proc. Ent. Soc. 1838, iii, p. 177). It is not 
yet, however, known upon what the nondescript Chalcid 
and Braconid, which are also sometimes found in the same 
nests (cf. Kirby, Bridgwater Treatise, 1835, ii. 335), are 
parasitic. 
153. Lhynchophora. 
Westwood (Mod. Class. ii, 142) refers to an unspecified 
Curculio, which was discovered to be attacked by hymeno- 
pterous parasites by Rev. William Kirby, F.R.S.; and 
Ratzeburg (Ichn. d. Forst. 11, 213) says that Hncyrtus 
flaminius has also been bred from some species of the same 
broad genus; further, Reissig (/zd. cit. iii, 89) raised a f of 
Bracon scutellaris from weevils in the leaves of sallow.
