Or 
Hymenopterous Parasites of Coleoptera, 2 
75. Aromia moschata, Linn. 
The larvee of the Musk Beetle are said by Brischke 
(Schr. Nat. Ges. Danz. 1880, p. 129) to be destroyed by 
Ischnoceros rusticus, Grav., which he considers synonymous 
with Odontomerus cornutus, Ratz. Thomson says that his 
Ephialtes heteropus (Opusc. Ent. 1249) was bred from this 
longicorn at Lund. 
76. Hylotrypes bajulus, Linn. 
From fir-wood in which Cerambyx bajulus had bored, 
Ratzeburg (Ichn. d. Forst. ii, 140) bred Cryptus minator. 
Bouché also found Ephialtes manifestator in this beetle (, 
119 et ii, 119); but Bracon leucogaster¥? is said to be 
by far its commonest parasite, and has been found—in 
Germany—in and upon dry wood, especially in beams of 
houses, about its borings (/.¢. 11, 35 et Marsh., Bracon. 
d’Europ. 1, 254). 
77. Callidium. 
Herr Wissmann bred several Aspigonus diversicoriis °° 
in Germany from very different insects, but all in dead 
wood—Lymexylon dermestoides, Mycetochara linearis and un- 
specified Callidia (Ichn. d. Forst. 11, 69). Marshall says 
that this Braconid (Bracon. d’Europ. 11, 252) has been bred 
“dun longicorne non determiné.”’ 
78. Callidium alni, Linn. 
There is a2 specimen of Pimpla instigator in Morley’s 
collection taken by Mr. E. C. Bedwell at “ Westerham, 4. 
6. 1900, sitting on a post, which was full of Callidivwm 
aint.” No parasitism is, however, suggested, for which 
indeed the Ichneumonid appears much too large. 
79. Callidium sanguineum, Linn. 
Ratzeburg tells us (Ichn. d. Forst. i, 128) that he found 
Cerambyx sanguineus upon several occasions preyed upon 
by Yorides precatorius™ in hornbeam logs; and this is con- 
firmed by Prof. Thompson (Opuse. Ent. viii, 775), who says 
of the latter, “Utklickt ur Callidiwm i Lund.” Giraud 
(Ann. Soc. Fr. 1877, p. 411) gives Opius ? caudatus, Wesm., 
as parasitic on this Longicorn, upon Perris’ authority. 
Marshall (Bracon. d’Europ. i, 228) has no doubt that it is 
further attacked by Doryctes gallicus, Reinh., and adds, “ I
