64 Mr. Ernest A. Elliott and Mr, Claude Morley on the 
May; and P. suspensus (11, 193), bred by the same observer 
from Pinus pinaster, in which both this species and C. 
notatus had bored—as preying upon it; and adds (di. cit. 
iii, 249), Hemiteles modestus,® H. melanarius and Pteromalus 
guttatus (iii, 236), which was always bred from fir, in one 
case containing only H. piniperda. Of Bracon Midden- 
dorfii 7 he says (ii, 33) that it was bred by Reissig on 
June 18th from fir bark, while the imagines of H. piniperda 
therein were still quite pale and only preparing for flight. 
... Herr Reissig sent him several two-lines long, dirty 
white, delicate, elongate cocoons from which the Braconid 
had emerged just below the apex. The dust from the 
boring adhered to them and also a distinct empty skin of 
a Hylesinus piniperda: the Braconid had certainly sucked 
it from outside. The same observer later sent it again to 
him, after the time of the hosts’ emergence. 
254. Phleophthorus rhododactylus, Marsh. 
Phicophthorus spartii is said by Giraud (Ann, Soe. Fr. 
1877, p. 427), upon Aubé’s authority, to be the host of 
Raphitelus maculatus, Walk. Nordlinger bred (Ichn. d. 
Forst. ii, 215) Storthygocerus subulifer®> (i, 208 et 11, 246) 
at Bordeaux, Grand Jouan and the Schwarzwalk; and 
several 2 2 of Bracon planus (ii, 33) at Bordeaux, from 
Hylesinus spartii; adding (ii, 31) that a great number of 
Bracon hylesini® emerged from it at Hohenheim. 
255. Polygraphus pubescens, Bach. 
From Hylesinus poligraphus, Nordlinger bred at Hohen- 
heim at least one Bracon hylesini® (Ichn. d. Forst. 11, 31), 
and both he and Radzay also bred B. Middendorffir,.” from 
this host (ii, 38 et iii, 82). Several specimens of Cosmo- 
phus klugii™ (ii, 72) were raised by the latter, as well as 
of both sexes of Pteromalus lanceolatus (11, 204) from the 
same borer, which Ratzeburg found was further parasited 
by Roptrocerus xylophagorum (ii, 209), P. multicolor *°8 (a1, 
193), P. capitatus, P. navis, and, doubtfully, P. #wmalus 
(ii, 215). 
256. Cryphalus binodulus, Ratz. 
Out of Bostrichus binodulus, its author says (lid, cit. 11, 30) 
that Radzay bred Bracon silesiacus (ii, 30) from beneath 
poplar bark ; and probably also Aphidius obsoletus (11, 59),
