Hymenopterous Parasites of Coleoptera. 491 
260a. PITYOPHTHORUS CONSIMILIS, Lec.* 
From Florida, Ashmead has described (Proc. Ent. Soc. 
Washington, 1894, p. 32) a Chalcid, parasitic upon this 
borer, under the name Cerocephala pityophthori; as well as 
a Proctotrypid, Aradophagqus fasciatus (Bull. U.S. Nat. Mus., 
1893, p. 166) from the same locality. 
2606. PITYOPHTHORUS QUERCIPERDA, Swz.* 
260y. BRACHYRHYNCHUS GRANULATUS, Say.* 
From these two species, also, Aradophagus fasciatus has 
been bred in Florida (J. ¢.). 
263. DRYOCAETES VILLOSUS, Fab. 
We have no British records of parasitism ; but Grosvenor 
bred a f Chaleid from it in June, 1908, at Bagley. 
265a. TOMICUS SEXDENTATUS, Born. 
Mayr brings forward from Lower Austria (Verh. z.-b. 
Ges., 1878, pp. 301, 304, 321) Zurytoma auricoma, which 
he says was bred from Hylurgus minor, Hylesinus fraxine 
and the present species by Oberforster Wachtl, from Pinus 
nigricans, near Vienna. 
266. Tomicus laricis, Fab. 
Perris also bred Amblymerus mirus, Walk., from Bostri- 
chus laricis in France (Dours, Cat., 102). 
267. Tomicus typographus, Linn. 
Possibly one or two of the Chalcids already instanced 
as attacking this species are synonymous with Hartig’s 
Diplolewis bimaculata, D. maculata and D. corticalis 
(Forstl. Conversationslex, 1834, p. 198), all of whick he 
bred in Germany from Bostrichus octodentatus, Payk.
