RHYNCHOTA.

95. Aphis papaveris, Fabr. 

 From an Aphis on Papaver somniferum, Giraud bred (Ann. 

 Soc. Fr. 1877, pp. 415-427) Praon volucre, Hal., Trioxys audits, 

 Hal., Allotria castanea, Htg., Encyrtus atheas, Walk., Pachy- 

 neuron aphidiphagus, Ratz., Isocratcs ceneus, Nees, and 1. vulgaris, 

 Walk. Reinbardt, however, bred quite different insects from 

 Aphis papaveris (Berl. Ent. Zeit. 1857, p. 77 ; L c. 1858, p. 12 ; 

 et Stett. Ent. Zeit. 1859, pp. 194-6), since these were Pachycrepis 

 clavata, W 'alk. , Aphelinus flavicornis , Forst., A. tibialis, Nees, and 

 Tetrastichus diaphantus, Walk. (cf. Gaulle, Cat. 103-107). 



96. Aphis cardui, Linn. 

 Aphidius cardui, Marsh. (Bracon. d'Europ. iii. 594) was bred 

 by Bignell in Devon very commonly from this species in the 

 middle of July, while of A. cirsii, Hal., he bred but one, in June, 

 and it is to this species that Marshall is of opinion (I. c. 589) 

 Buckton refers as the commoner parasite. From an Aphis 

 feeding on Carduus nutans Kieffer records his new Lygocerus 

 antennalis, var. subserratus. 



97. Aphis instabilis, Buck. 

 Only Bignell has recorded (Trans. Devon. Ass. 1901, p. 690) 

 the presence of parasites upon this species ; he bred Aphidius 

 cirsii, Hal., from it in South Devon, on June 13th, 1883. 



98. Aphis sambuci, Linn. 

 Gaulle tells us that the Cynipid, Allotria circumscripta, Htg., 

 has been bred from this species, which is said to be common 

 in Britain (cf. Cat. 26). I took it at Cosham, Hants, July, 

 1909.
