Hymenopterous Parasites of Coleoptera. 51 
also bred from it by Giraud (Laboulbene, Ann. Soc. Fr. 
1877, p. 408), where Bracon variator, Nees, Systasis en- 
cyrtoides, Walk., and Pteromalus auwronitens, Forst., are 
also indicated as attacking Gymnetron campanule. 
202. Gymnetron antirrhini, Payk. 
Sigalphus pallidipes, Nees, is said by Marshall (Bracon. 
d’Europ. i, 315) to be a common parasite of this species ; 
he adds (lib. cit. 320) that S. obscurellus also preys upon 
Gymnetron noctis, Herbst.: “des galles produites sur le 
lin sauvage.” 
203, Gymnetron beccabunge, Linn. 
From this weevil, Brischke (Schr. Nat. Ges. Danz.) has 
bred an undetermined species of Bracon, together with 
Pteromalus curculionordes, 
204. Gymnetron collinus, Gyll. 
Bignell writes of Sigalphus obscurellus, Nees (Trans. 
Devon. Assoc. 1901, p. 667): ‘Bred from Gymnetron 
collinus, a beetle feeding on the unripe seeds of the toad- 
flax, Linaria vulgaris, September 19th, 1880.” 
205. Gymnetron villosulus, Gyll. 
In his Naturgeschichte der Insecten (1854), Bouché 
tells us that his Pteromalus curculionoides feeds upon the 
larvee of Gymnetron villosulus (cf. Westwood, Mod. Class. 
ii, 159). 
206. Gymnetron teter, Fab.* 
Kirchner (Cat. 105) gives “ Pimpla gymnetri, Ratz., 
Preussen, Gez. aus Curculio teter”; as recorded by the 
latter (Ichn. d. Forst. ii, 96 et iti, 103), bred from the 
knot-like swellings caused by the larve of this beetle on 
the previous year’s, already woody, stems of Verbascum 
nigrum. 
207. Gymnetron asellus, Grav.* 
At Ann. Soc. Fr. 1877, p. 413 e¢ seqg. Laboulbéne 
records Bracon gymnetri, Gir., B. ? dichromus, Wesm., and 
Entedon curculionwm, Gir., from this beetle.
