HYMENOPTEROUS PARASITES OF RHYNCHOTA. 341 



been bred from an Aphid on Bupleurum (the present species 

 occurs on the allied Apium gravcolens), is synonymous with the 

 latter, as may also be said of A. mullensis, Cam., bred from 

 Aphids on B. falcatum (Gaulle, Cat. 26) . Aphidius dauci, Marsh., 

 has been bred from the present species by Bignell and Marshall 

 in Devonshire on Sept. 30th, 1886, and July 10th, 1888 (Marsh. 

 Br. d'Europ. ii. 602), and it is perhaps the larva of this direct 

 parasite, which Buckton figures (Mon. Aph. ii. pi. xliii.), lying 

 subcutaneously in a curved position within the abdomen of an 

 apterous female of S. pastinacece. Aphidius exiguus, Hal., Allotria 

 minuta, Htg , A. pusillima, Gir , Encyrtus atheas, Walk., and 

 Agonioneurus daucicola, Forst. (?MS.)» were raised by Giraud 

 (Ann. Soc. Fr. 1877, pp. 415-6) from Aphids, most probably of 

 this species, on Eryngium campestre and Conium maculatum. 

 Allotria perpusilla, Kief., is recorded from an Aphid on Conium. 



75. Siphocoryne xylostei, Schr. 



Aphidius avence, Hal., and A. lonicerce, Marsh., were both 

 bred from this too common species in Devon by Bignell, who also 

 raised the former's hyperparasite, Allotria cursor; but A. loni- 

 cerce would appear to be rare, since but eight females and two 

 males were obtained on July 16th, 188-1. Bignell also there raised 

 Praon longicorne, Marsh. (Trans. Devon. Ass. 1901, p. 688). 

 Lygocerus carpenteri, Curt.,, is also somewhat vaguely given as 

 attacking this species by Gaulle and Dalla Torre. 



76. Siphocoryne foenicidi, Pass. 



In Devonshire, Marshall bred six specimens of his Aphidius 

 brassier, comprising both sexes, and Bignell a single male on 

 July 2nd, 1881, from this species ; and Cameron (Phyt. Hym. iii. 

 233) records Allotria circumscripta from Aphids on fennel. 



77. Siphocoryne caprece, Fabr. 



The only direct record we have from this species is that of 

 Bignell (Trans. Devon. Ass. 1901, p. 688 et Br. d'Europ. ii. 594), 

 who bred Aphidius cardui, Marsh., very commonly in Devon- 

 shire. Possibly some of the species under MelanoxantJius 

 {supra) and the genus Aphis {infra) belong here ; but none are 

 sufficiently explicit.
