476 Messrs. E. — and Claude Morley on the 
which it moved briskly with a lashing motion. No organs 
could at first be seen in this animalcule, but a small 
vesicle soon appeared therein, increased in size and finally 
developed itself into the larva of one of the Pteromalidae” 
(Ent. Weekly Intelligencer, 1857, p. 183, e¢ lib. ctt., ix, 
ser. 1, pp. 461-464, pl. xvi A: “ Upon the Mode of Genera- 
tion of a Hymenopterous Insect of the Family of the 
Pteromalidae”); this was a hyperparasite, bred at Turin 
in some numbers. Siga/phus caudatus has also been found 
to prey upon this host by Goureau (Dours, Cat., 77). 
161. Apion apricans, Herbst. 
Mayr bred his Holaspis apionis, as well as Hurytoma 
salicis, Walk. = gibba, Boh., from this species in Germany 
and Austria (Verh, z.-b. Ges., 1874, p. 84, e¢ 1878, p. 308). 
And Pteromalus prone, Walk., Dours records (Cat., 104) 
as attacking it in France on Goureau’s authority. “It 
appears that M. Guérin bred, either from the larvae or 
pupae of A. apricans, the minute fly called by Haliday 
Calyptus, the Hubazus macrocephalus of Nees. [Described. ] 
This parasite does not seem to be exempt from persecu- 
tion, for M. Guérin found with the Hubazus a beautifully 
coloured fly, called by Walker Petromalus (sic) pione, 
which is suspected to be parasitic upon the Hubazus” 
(Curtis, F. I, 481). Mayr says of Hurytoma salicis (1. ¢., 
p- 382): “TI have often bred this species from the faded 
heads of Z'rifoliwm pratense, in which Apion trifolia and 
fagi — identified by Herr Ludwig Millar—lived; Dr. 
Reinhard obtained it from clover heads from Saxony, in 
which Apion apricans lived.” 
162. Apion bohemani, Thoms. 
Three specimens of a new species of the Chalcididous 
genus Yurytoma have been described as also attacking 
this species by Mayr (Verh. z.-b. Ges., 1878, pp. 303 e¢ 
seqq.) under the name #. ononis in Austria; he bred them 
from pods of Ononis spinosa, in which larvae of Apion 
ononidis were living. 
165. Apion loti, Kirby. 
Mayr bred (Verh. z.-b. Ges., 1878, p. 303) Hurytoma 
salicis, Walk. = gibba, Boh.,in Lower Austria; he says:
