which he bred Tridymus aphidum (Ichn. d. Forst. ii. 183 et 197), 

 were Coccids ; or, if Aphids, were synonymous with C. corticalis, 

 Kalt. 



134. Chermes abietis, Linn. 



Gaulle (Cat. 98) records the Chalcid, Encyrtus scaur us, Walk., 

 from Physokennes abietis. 



135. Chermes laricis, Htg. 



His Aphidius laricis was first bred by Haliday from an Aphid 

 on Larix europcea, and probably of the present species ; he says 

 of it, " Habitat in Larice e cujus Aphidibus prodiit mihi " (Ent. 

 Mag. 1835, p. 97). It has not again been bred in Britain, but 

 the same host is doubtless referred to b} T Giraud, who says (Ann. 

 Soc. Fr. 1877, p. 416) that he raised both Aphidius pini, Hal., 

 and A. laricis, Hal., from an Aphid on Pinus larix; and, from 

 apparently the same species of host, he also bred {I.e. p. 434) 

 his Megaspilus laricis. Gaulle (Cat. 113) records the Procto- 

 trypid, Lagy nodes pallidus, Boh., from Chermes laricis. 



136. Chermes bauhini, ?auct.* 

 A Chalcid, Psilophrys (Encyrtus) longicomis, Walk., is recorded 

 (Cat. 98) by Gaulle from this species. 



137. Phylloxera caryce-scissa, Kiley.* 

 From this Floridan species Ashmead (Trans. Amer. Ent. Soc. 

 1881, Proc. p. xxx. et 1894, p. 328) records the emergence of his 



Phylloxeroxenus phylloxera. 



138. Tychea phaseoli, Pass. 

 Bignell bred Praon abjectum, Hal., from this species in Devon- 

 shire on July 23rd, 1883 (Marsh. Bracon. d'Europ. ii. 534), 

 together with the abundant Aphidius ervi, Hal., and probably the 

 latter's hyperparasite, Isocrates ceneus, Nees. 



139. Rhizobius pilosellce, ? auct.* 

 The only mention I find of parasites upon this species is in 

 Gaulle's 'Catalogue' (p. 103), where the Chalcid, Asaphes vul- 

 garis, W T alk., is said to prey upon it. 



140. Undetermined Aphidid^e. 

 From the following list of parasites, which have been recorded 

 from unidentified members of this family, I have omitted all
