187. Cuculio abietis, Linn. 
Ratzeburg gives (Ichn. d. Forst, 11. 213) phialtes 
tuberculatus, Bracon hylobit and, doubtfully, Pteromalus 
multicolor, as parasitic upon Hylobius pint. Of B. hylobia 
Nordlinger bred in May 40 2 9 and 4 $f from this species, 
each of whose larve supports about ten parasites; the 
cocoons of the latter are firm, oat-shaped and papyraceous, 
woven among their hosts’ frass and dead bodies, and often 
constructed at the end of the beetles’ borings, beneath fir 
bark (/. ¢. 11,38). A single ZL. tuberculatus was bred at 
the end of July at Hohenheim from a Weymouth pine in 
which this weevil lived ; it had apparently emerged from 
an elongate cocoon, presumably of its own construction 
(2. c. ii, 100). Taschenberg says (Zeits. Ges. Nat. 1863, 
p. 267) that it is also preyed upon by Pimpla terebrans, 
which is recorded from Curculio pint (Ichn. d. Forst. 11, 38). 
188. Pissodes notatus, Fab. 
Much attention was paid to the parasitism of this species 
by Ratzeburg, who records (Ichn. d. Forst. i, 23, 1, 214 et in, 
249) the attacks of twenty-nine different Hymenoptera 
upon it, including Hupelmus azwreus,"> Hurytoma sp., 
Pteromalus pellucens and P.? emulus. Hemateles melanarius 
and H. modestus'® (iii, 153-4) were both bred by Reissig 
from young fir trees containing, principally, Cureulio notatus 
and Hylesinus piniperda; Neurateles papyraceus (i, 86) 
were bred, probably from this weevil, from firs near 
Saarbriicken ; Hphialtes carbonarius (i, 99) emerged at 
Neunkirchen in Rhenish Prussia, probably from this beetle ; 
Pimpla linearis (ii, 93) was certainly bred from Cureulio 
notatus, by both Reissig and Ratzeburg from both young 
firs and fir-cones, together with P. latiecps (11, 94 et 111, 100), 
in the same locality. Quantities of both sexes of Bracon 
disparator \" (i, 46) were bred from fir billets infested by 
this weevil; two 22 B. incompletus (i, 44) were bred from 
fir, probably from this beetle, in Germany; 2. labrator 
(i, 47 et ii, 40) was bred at Borutin in Upper Silesia from 
fir logs infested with C. notatus ; both sexes of B. palpebrator 
(i, 47 et ii, 39) were bred in quantities from fir wood full 
of these larvee at Trier; ~ % of B. sordidator (G. 48) were 
bred, with the last-named species, in Upper Silesia from 
fir logs, probably also from this beetle. rachistes 
atricornis 3+ (11, 28) is one of its commonest parasites, in
