association of the Braconid, but expresses his opinion that 
it is closely allied to, if not actually identical with, 
Clinocentrus exsertor, Nees. 
42. Hylecetus dermestoides, Linn. 
From this species, Wissmann bred in Germany (Ichn. d 
Forst. 1, 69) several specimens of Aspigonus diversicornis * 
and perhaps also a species of Heicon.

43. Ptinide. 
Another of Westwood’s general statements (Mod. Class. 
ii, 143) is: “ A small, pretty, spotted-winged Cryptus enters 
our houses to prey upon the larve of the Ptinide; as do 
also Spathius clavatus“’ and Hecabolus sulcatus” ; the first- 
named is certainly Hemiteles areator, Panz. (cf. Morley, 
Ichn. Brit. 1, 133). Pinus fur and Niptus hololeucus are, 
however, the only common domestic Ptinidx, and there is 
no record of hymenopterous attacks upon these species. 
44, Hedobia imperialis, Linn. 
Westwood may, however, be correct in the above state- 
ment, since the parasitism of Hemiteles areator upon 
Ptinus imperialis—by no means a domestic species, at least 
in Britain—is recorded by Ratzeburg, who says (Ichn. d. 
Forst. 11, 153) that Nordlinger bred this parasite at 
Hohenheim from old acacia posts together with P. 
imperialis. The latter also bred (/. ¢, 11, 152) Hupelmus 
inermis**° from an ailing beech in which this beetle, 
among others, was dwelling. 
45. Dryophilus pusillus, Gyll. 
Brachistes interstitialis °° (1. ec. 1, 54) and BLothriothorax 
Jumipennis (iii, 194) were bred by Nordlinger at Stuttgart 
from, respectively, dry spruce twigs and a larch branch, 
in which Anobium pusillum was boring. 
46. Anobium. 
Westwood says (Mod. Class. ii, 159), “I have observed 
Perilampus angustus ** on palings perforated by Anobia.” 
Ratzeburg quotes this, and adds ntedon conjinis from 
France (Ichn. d. Forst. 1, 66), a % #. longiventris in a German 
fir twig, orides eryptiformis (il, 115) and Hemateles 
palpator * of which Wissmann cut several out of oak bark
