112 THE ENTOMOLOGIST. 



91. Planchonia delicata, Green. *^ 

 From Ceylon we know two parasites of this species (Proc. 

 U. S. Nat. Mus. 1896, pp. 635 et 637), named by Howard 

 Encarsia planchonice and Encyrtus {Adelencyrtus) Planchonice 

 respectively. 



92. Pkosopophoea.* 

 An uninstanced species of a genus of this name is said by 

 Howard (Eevis. Aphel. 1895, p. 21) to be attacked by Perisso- 

 pterus pulchellus, How. 



93. Aonidia cornigcr, Green.* 

 From an insect of this name, Encarsia aonidice, Howard, is 

 recorded (Proc. U. S. Nat. Mus. 1896, p. 636). 



94. Phenacoccus.* 

 Ashmead has instanced (1900, p. 388) Aphycus townsendii, 

 How., from a species of this genus feeding on cotton. 



95. Phenacoccus cavallice, CklL* 



The same author has devoted a short article to " The Hym. 

 Par. of P. cavallice, Ckll." (Canadian Entom. 1902, p. 301), 

 which he says include Cheiloneurus dactylopii, How., Sicpiiphora 

 dactylopii, Ashm., his new Blepyrus phenacocci, with its new 

 hyperparasite, Tetrasticlms blepyri, all bred in New Mexico. 



96. Tachardia albizzice, Green.* 



Microterys tachardice, How., is said to prey upon this species 

 in Ceylon by Ashmead (1900, p. 393). 



97. Rhizococcus.* 

 And from a member of this genus feeding on a composite 

 plant the same author describes Signiphora rhizococci (1900, p. 

 411), of which one specimen was bred by F. Noack in July, 1897, 

 in Brazil. 



ALEURODID.E. 

 98. Aleurodes. 

 From members of this curious genus are recorded Howard's 

 Aphelinids, Eretmocerus califor7iicus (Bull. U. S. Agric. Ent. 

 Techn. 1895, p. 16), Pterothrix flavimedia (Rep. Ent. U. S. 

 Agric. 1881, p. 369), Eucarsia coquilleti, E. luteola, and E. angelica 

 (Revis. Aphel. N. America, 1895, pp. 29 et 30). Douglas remarks 

 (E. M. M. 1894, p. 87) upon the immunity from parasitic attacks 

 of his A. rnhicola throughout its exposed hybernation in Britain. 



99. Aleurodes chelidonii, Linn. 

 Dalla Torre gives (Cat. Hym. v. 278) Evpelmvs urozonns, 

 Dalra., as a parasite of this species upon Rondani's authority;
