Hymenopterous Parasites of Coleoptera. 39 
mens of the same species; he bred it at the end of June 
1898. Sometimes only ff will emerge from a whole 
fungus-full of Orchesia, as was the experience of Mr. E. G. 
Bayford, about Barnsley in 1898, who bred it from the 
pup of the beetle. It has been suggested that this 
species may have been the host of Hemuteles niger, which 
has been bred from a ligneous fungus (cf. Morley, Ichn. 
Brit. 11. 146). 
Morley has invariably bred Meteorus obfuscatus, wherever 
O. micans occurs (from Soletuws on old elm-trees about 
Ipswich); a fungus taken on Oct. 17th, 1897, produced 5 f 
and 2 2 Thersilochus moderator on April Ist, 1898; and 
1 f with 3 2Qof the same species, 8 f and 13 2 Meteorus 
obfuscatus, and 19 O. micans, had also emerged from it by 
Jan. 12th, 1901. A second fungus, taken Dec. 30th, 1899, 
yielded only 2 2 AZ. obfuscatus and 2 O. micans by June 
22nd, 1900. From a third fungus obtained in 1902 were 
bred by June 17th, 1903, 26 O. micans,50 (17 92) M. 
obfuscatus, 10 (52.2) T. moderator, 5 (1 2) Proctotrypes par- 
vulus, Hal., 2 red-bodied Cecidomyia and 1 Phalacrus 
corruscus ; there can be but little doubt, in lack of direct 
evidence, that the Zhersilochus is hyperparasitic, through 
the Meteorus, upon the Orchesia; the appearance of the 
Proctotrypes is more difficult to explain, though several 
times before bred from fungi; the Dipteron doubtless sub- 
sisted upon the fungus itself, in which the Phalacrid 
Coleopteron was probably no more than hibernating. 
147. Hallomenus. 
Prof. C. G. Thomson (Opusc. Ent. xii, 1360) says of 
Porizon: “ Hvad angir lefnadssittet kainner man foga 
derom ; ett par arter hafva klaickts ur Coleoptera—Orchesia 
och Hallomenus— ; nigra andra lefva parasitiskt hos 
Cynips.” And adds of Diaparsus gulvipes, Grav. (lib. cit. 
1378), “utlickt ur Hallomenus.” 
148. Hallomenus humeralis, Panz. 
A Braconid, Diospilus filator, Nees, is said by Giraud 
(Ann. Soc. Fr. 1877, p. 411) to have been bred by Perris 
from this beetle. 
149. Carida affinis, Payk.
