THE ZOOLOGIST. 



87. Aphis hieracii, Kalt. 



In Devonshire, Bignell has bred Praon abjectum, Hal., but 

 Haliday himself (Ent. Mag. 1833, p. 491) says of his Trioxyi 

 heraclei, which alone he bred from the Aphids of Heracleum 

 sphondyUum, ''Habitat in Aphidibus Heraclei Sphondylii florentis 

 Julio mense vulgatissimus, posthac vix obvius." It is surprising 

 more parasites have not been bred from so ubiquitous a host. 



88. Aphis epilobii, Kat. 



Praon abjectum , Hal., has also been bred in Devon by Bignell 

 from this species on Sept. 24th, 1883 (Trans. Devon. Ass. 1901, 

 p. 688), and Gaulle (Gat. 26) tells us that Allotria breuitarsis, 

 Thorns., also preys on an Aphis sur Ejnlobium. 



89. Aphis euonymi, Fabr. 



I have been unable to clear up the mystery attaching to Dalla 

 Torre's record of Miscogaster nitidus, Walk., from " Britannia " 

 only, and yet bred by Kondani from this host ; it is certainly 

 not mentioned thence by Walker (Ent. Mag. 1833, p. 459 et 

 Mon. dial. 280). 



90. Aphis lychnidis, Linn. 

 Bignell bred Aphidius lychnidis, Marsh., from this species 

 on April 29th, 1883, in Devonshire (Marsh. Bracon. d'Europ. ii. 

 607). 



91. Aphis ilicis, Kalt. 

 Probably this was the " Aphis on holly " from which Bignell 

 (Trans. Devon. Ass. 1901, p. 690) raised Aphidius matricarue, 

 Marsh., on June 19th, in Devonshire ; it is not recorded as 

 British, though thought by Buckton and Walker to be probably 

 synonymous with our abundant Aphis hederce, from which no 

 parasites are recorded. 



92. Aphis jacobcece, Schr. 



Marshall tells us (Bracon. d'Europ. ii. 594) that Aphidius 

 cardui has been commonly bred from Aphis jabcobce in England. 



93. Aphis rumicis, Linn. 



This polyphagous Homopteron has been noticed to be some- 

 what extensively preyed upon by Hymenoptera, and it would be 

 of great economic importance if some permanent natural enemy 

 could be established. So far from that, we at present have but
