Hymenopterous Parasites of Coleoptera. 41 
154. Apoderus. 
At lib. cit. 11, 213, Ratzeburg tells us that an unspecified 
Apoderus has been found to be attacked by Lneyrtus flavo- 
maculatus and also (l.c. ii, 249) by Ophionewrus simplex.® 
155. Apoderus coryli, Linn. 
Ratzeburg says (/. ¢. 11, 94) that his single f of Pimpla 
longiventris was found in an immature condition in a hazel 
leaf rolled by this beetle and thought consequently that 
it had undoubtedly been bred there. Reissig also bred 
(1. c. iti, 97) Pimpla favipes®™’ and (iu, 217) EHlachestus 
leucobatus from the same host. 
156. Attelabus curculionoides, Linn. 
Two specimens of Ophionewrus simplex*® were bred by 
Herr Reissig (Ichn. d. Forst. iii, 197) out of the little 
larvee of Apoderus curculionoides in rolled oak leaves at 
Darmstadt. 
157. Byctiscus betuletr, Fab. 
Rev. T. A. Marshall (Bracon. d’Europ. ii, 149) records 
Calyptus tibialis, Hal., which he thinks synonymous with 
Brachistes politus, Ratz., from this species, upon the latter’s 
authority—Nordlinger found B. politus in a pear leaf rolled 
by this weevil early in June at Winnenden (Ichn. d. Forst. 
iii, 27) ;—he is however sceptical of the record from it of 
Apanteles hoplites (cf. Melasoma tremule, ante).  Ratze- 
burg also mentions (/. ¢. ii, 214) Bracon discoideus, frequently 
bred from aspen leaves rolled by this beetle (p. 38); J/icro- 
gaster levigatus, one ¢ bred by Reissig (p. 50); Pimpla 
flavipes, obtained in masses from Curculio betulets in rolled 
aspen leaves in the middle of July (p. 91); and Hlachestus 
carinatus, of which four specimens were bred from rolled 
aspen leaves—probably tenanted by this weevil—by 
Reissig (p. 173); as well as (au, 249) Ophionewrus 
simplea,4?6 
158. Byctiscus populi, Linn. 
Herr Reissig bred Bracon discoideus from Rhynchites 
popult in rolled poplar leaves (Ichn. d. Forst. ii, 37). 
159. Deporaus betule, Linn. 
Ophioneurus signatus ”” is instanced by Reissig (lid. cit. 
iii, 249) as bred from leaves rolied by Rhynchites betulx.
