168. Apion urticarium, Herbst. 
Perris has also raised Péeromalus muscarum, Htg., accord- 
ing to Laboulbene (J. ¢.), from Apion vernale. 
169. Apion violacewm, Kirby. 
Entedon curculionum, Giraud, is said by its author (Ann. 
Soc. Fr. 1877, p. 432), upon the authority of Perris, to 
prey, among other weevils, upon this species. 
170. Apion brevirostre, Herbst.* 
M. Edouard Perris, who has done such good work in 
‘ this genus, is also said (Joc. cit.) to have bred Hulophus 
atroceruleus, Nees, and Tetrastichus rosarwm, Forst., from 
this Apion in France. 
171. Apion sulcifrons, Herbst.* 
Giraud records (Ann. Soc. Fr. 1877, pp. 425 et 432) his 
Eurytoma apionum and Entedon nitens from Apion sulerfrons, 
in the latter case upon Artemisia campestris, Linn. 
172. Apion Perrisi, Wenck.* 
From a species thus named, Laboulbéne (Joc. cit. p. 414) 
says M. Perris bred Bracon rufator, Gir., in France. 
178. Apion consimile, ? MS.* 
Laboulbéne also records (/. ¢ p. 432) Hntedon longi- 
ventris, Ratz., bred from Apion consimile by Dr. Giraud. 
174, Otiorhynchus ligneus, Oliv. 
Bracon Otiorhynchi 2 and B. Barynoti g, described by 
Boudier, are the sexes of Ganychorus tuberculatus,*” Wesm. 
(Nouv. Mém. Ac. Brux. 1835). A single larva of the ¢ was 
bred from Otiorhynchus ligneus and a single larva of the g 
from Barynotus moerens, after the perfect beetles had been 
pierced with pins for preservation. These larvae, which 
emerged from the abdomens of their respective hosts, spun 
their cocoons on to the pins, beneath the beetles’ bodies ; 
they were bred at Montmoreucy (cf. Boudier, Ann. Soc. 
Fr. 1834, pp. 327-836, et Westwood, Mod. Class. ii, 143). 
What do we not lose by too thoroughly killing our cabinet 
specimens now-a-days!
