Hymenopterous Parasites of Coleoptera, 65 
which emerged in this beetles’ breeding cage, though 
possibly other Coleoptera were also in the enclosed large 
section of wood. 
257. Cryphalus fagi, Fab. 
Bracon hylesini is recorded (lib. cit. iii, 249) from 
Bostrichus fagt. 
258, Cryphalus picee, Ratz. 
Only Loptrocerus xylophagorum was bred by Nordlinger 
(Ichn. d. Forst. 11, 209) from Bostrichus picee. 
259. Cryphalus tiliv, Panz. 
A single ¢ Spathius exannulatus’ and a species of 
Hurytoma are alone recorded (lz. cit. 1, 43) from Bostrichus 
tiliv, though Ratzeburg bred “countless myriads” from 
lime trees. 
260, Pityophthorus pubescens, Marsh. 
Dr. Ratzeburg (Ichn. d. Forst. 1i, 212) bred Roptrocerus 
aylophagorum, DPteromalus capitatus, P. navis and perhaps 
P. emulus (11, 203) from Bostrichus pitiographus; he adds 
that Nordlinger also raised P. malticolor®® (11, 193) from 
the nests of this borer at the end of June-—at the time of, 
or rather later than, their hosts’ emergence; as well as 
P. navis (ii, 205) at Hohenheim in spring from the same 
beetle, with B. poligraphus and B. abietis, in spruce. 
261. Xylocleptes bispinus, Duft. 
Pteromalus gravenhorstii*8 was bred by Nordlinger (did. 
cit. il, 245) from Bostrichus bispinus in clematis. 
262. Dryocetes autographus, Ratz. 
From Bostrichus autographus, Ratzeburg (J. ¢. ii, 211) 
records only Péeromalus multicolor? 
263. Dryocetes villosus, Fab. 
Marshall (Bracon. d’Europ.) says Microdus rugulosus, 
Nees, and perhaps Chelonus neesii, Reinh., have been bred 
from this borer. Nordlinger (Ichn. d. Forst. ii, 188 et 
209) raised Pteromalus bimaculatus, P. multicolor®® and 
Ropirocerus xylophagorum from Bostrichus villosus in oaks 
at Grand Jouan, in France.
