Hymenopterous Parasites of Coleoptera, 53 
212. Nanophyes lythri, Fab. 
Laboulbéne records (Ann. Soc. Fr. 1877, p. 420) that 
Perris has bred Hupelmus Degeert, Dalm., and (p. 430) that 
Dr. Giraud also raised Pteromalus vaginule, Ratz., from 
this beetle. 
213. Cionus scrophulariv, Linn. 
Bignell says (Entom. 1885, p. 152) that he bred Hemi- 
machus instabilis,* Forst., from a pupa of this beetle, 
August 23rd, 1882. Thomson records (Opusce. Ent. x, 980) 
Hemiteles awreator, “ Klackt ur Cionus scrophularix.” And 
Bridgman tells us (Trans. Norf. Soc. 1895, p. 114): “Mr. 
Thouless gave me a female Pezomachus corruptor, Forst., 
which he had bred from the larva of Cionus scrophularia, 
a beetle which he took at Horsford, August 1894. This 
is interesting, as it is seldom that ichneumons are bred 
from beetles ; it may be due, in a measure, that beetles 
are not bred to the same extent that butterflies and 
moths are.” This example of P. corrwptor, which I have 
examined and found correct, is now in the Norwich Castle 
Museum [C..M.]. 
214, Cionus tuberculosis, Scop. 
Brischke records his 9 Pezomachus thoracicus (Schr. Nat. 
Ges. Danz. 1881, p. 351): “ Aus Cionus verbasci erzogen ” ; 
and indicates Hntedon discolor as preying upon the same 
species. 
215. Sterconychus fraximi, DeG.* 
This weevil is said to be attacked by the Braconid, 
Blacus ruficornis, on the strength of a single example 
which was bred by Dahlbom, who writes im Jit. (Ichn. 
d. Forst. ii, 61): “Exclusus e Pupa Rhychzni (Cioni) 
fraxini, Gyll, 7th Septb., Lund.” Professor Kawall 
also bred (Stett. Ent. Zeit. 1855, p. 231) two species of 
Pteromalus, and a specimen of Pezomachus agilis, Fab., 
var. 4 b, Gray., from Cronus fraxini. 
216. Cryptorrhynchus lapathi, Linn. 
Kirchner records (Cat. 108) phialtes tuberculatus; 
Foure., as parasitic upon this species; and Ratzeburg in- 
stances (Ichn, d. Forst, 11, 218) Pimpla cicatricosa®” and
