Hymenopterous Parasites of Coleoptera. 21 
Hartz; and Wissmann expressly states that he “bred it 
from A, abietis and angusticolle” ; Reissig, however, who 
has bred it most frequently, asserts it to prey upon the 
above Tortrix; Ratzeburg believed it was parasitic upon 
both the Lepidopteron and Coleoptera (id. cit. 1, 56 et ii, 
69). Nordlinger also bred the B. punctatus twice singly 
at Hohenheim (11, 28 et iti, 244) from spruce cones along 
with Anobium abietis. Giraud, too (Ann. Soc. Fr. 1877, 
p- 412), bred Aspigonus abictis, Ratz., from “ Anobiwm 
abietis, dans cones du sapin,” as well as (p. 427) Anogmus 
abwetis, Gir. 
57. Ptilinus pectinicornis, Linn. 
Curtis first (B. E. pl. dvii) bred his Hecabolus sulcatus 
from this beetle. Ratzeburg found (Ichn. d. Forst. ii, 215) 
it was preyed upon by his Hemiteles completus which 
Reissig (/. c. 130) bred from this beetle in poplar in the 
middle of May, Hupelmus wmermis*° and, perhaps, Lis- 
sonota arvicula,” Polysphincta elegans, P. soror, with Xorides 
cryptiformis. None of these were raised from it by Giraud 
(Ann. Soc. Fr. 1877, pp. 415 et 419), who says Spathius 
clavatus,“’ Panz., and Halticella rufipes, Oliv., attack it. 
The original parasite, H. sulcatus, Curt., was again bred 
from it by Brischke (Schr. Nat. Ges. Danz. 1880, p. 136) ; 
and Wissmann (Ichn. d. Forst. 11, 35) bred a great number 
of § ¢ only, which were even more like Curtis’s illustration 
than those from Ptilinus costatus. Haliday (Ent. Mag. iv, 
p. 49) bred it from the same host. 
58. Ptilinus costatus, Gyll.* 
A male and two females of Bracon (Hecabolus) sulcatus 
were taken by Hartig on willows in the act of investigating 
the borings of this beetle (/.¢. ii, 34); and Reissig bred a 
single specimen of Pteromalus distinguendus, Forst., from 
the same host (iii, 233) im poplar wood. 
59. Ochina hederx, Miill. 
Writing of this species (Mod. Class. i, 272), Westwood 
tells us: “A. Cooper, Esq., R.A., has informed me . 
that it is preyed upon in the larva state by Cleonymus 
depressus.” Wissmann repeatedly bred Spathius erythro- 
cephalus from Anobium Hederx (Ichn. d. Forst. 11, 43) ; 
Nordlinger bred both sexes of Sigalphus aciculatus **° from
