ii, 152) that he bred from Bostrichus suturalis a single of 
Eupelmus inermis*® at Neustadt. 
249. Carphoborus (Dendroctonus) minimus, Fab.* 
From fir wood bored by this species, Ratzeburg bred 
several Entedon hylesinorwm (Ichn. d. Forst. 1. 167) of 
both sexes ; Hurytoma pinctorum (iii, 220) from Bostrichus 
minimus, together with Pteromalus azureus (1. ¢. et 11, 235) 
from bored fir twigs in May, and Lutedon pinetorum; from 
fir wood, with B. minimus and B. bidens, emerged Piero- 
malus azurescens (ili, 235), and, from B. minimus alone, he 
bred P. vicarius (iii, 241), together with P. azwreus, Entedon 
pinetorum, Hurytoma pinetorum and Spathius brevicaudis. 
Nordlinger at Hohenheim raised three different Chalcids 
from this host: a single $ of Pteromalus ramulorum 
(ii, 201) in August; P. dubius*® (ai, 192 et ii, 234) also 
in August; and HLntedon caudatus (ii, 170).  Pteromalus 
siccatorum (iii, 240) and Bracon hylesini!® are also indicated 
(iti, 249) as probably preying on this beetle. 
250. Phleotribus olex, Fab.* 
Fitch reminds us (Entom,. 1880, p. 258) that Bargaghi 
has bred Spathius rubidus from this host. 
251. Hylurgus. 
Cheiropachus quadrum is referred to by Westwood (Mod. 
Class. ii, 159) as bred from members of this genus by 
Fonscolombe. 
252. Hylurgus minor, Htg. 
From Hylesinus minor, Ratzeburg (Ichn. d. Forst. ii, 
191) records both sexes of Péteromalus azureus, as 
numerously bred by Nordlinger at Hohenheim in August. 
253. Hylurgus piniperda, Linn. 
Cooper (Ent. Mag. ii, p. 116) recounts the parasitism of 
Cheiropachus pulchellus wpon this species. Ratzeburg 
(Ichn. d. Forst. 11, 215) gives Bracon palpebrator (1, 89), 
bred from Pinus pinaster, im which H. piniperda and 
Curculio notatus lived; Pteromalus latriellei® (ii, 192), 
one bred from this borer by Reissig; P. lwnula (11, 193), 
one bred at Neustadt out of this host; P. pellucens, P. 
multicolor®® (ii, 194), raised from it by Nordlinger in
