HYMBNOPTEROUS PARASITES OF COCCID^. Ill 



85. Coccus nlmi, Linn. 

 From this species, which Mr. Newstead considers probably 

 synonymous with Lecanium caprece, Linn., Walker has described 

 (Ann. Nat. Hist. xiv. (1844), p. 185) his Encyrtus macharas. 



86. Coccus phalaridis, Linn. 



This species is referred to the genus Lecanium by most 

 authors, but Mr. Newstead tells me it is in any case unrecogniz- 

 able. From it Dalla Torre gives (Cat. Hym. v. 247) Trichomas- 

 thus (Sceptrophorus) cyaneus and cyaneifrons, Dalm., apparently 

 upon Kollar's authority, but cf. the synonymous Encyrtus stigma^ 

 Walk. (Ann. Nat. Hist. xix. (1847), p. 228) in respect to the 

 former, which was also bred from " cottony cocoons " — doubtless 

 Coccids — on a leaf by Curtis (Brit. Ent. fol. 395). Mayr (Verb, 

 z.-b. Ges. 1875, p. 745) raised Chiloneunis formosus, Boh., from 

 it ; together with {lib. cit. p. 695) Aphycus hederacem, West., 

 which I took on ivy at Monk Soham on 8th June, 1908. 



87. leery a purchasi, Mask.* 



The parasites of this species are stated to be the Pirenid 

 Ophelosia crawfordi, 'Riley ('Insect Life,' 1890, p. 248), Coccopha- 

 gus californicus, Howard {I. c. 1889, p. 269), Encyrtus dubiiis, 

 How. {nee Fonsc. ; I. c. 1888, p. 270) from California, and the 

 Proctotrypid Phanurus {Thoron) opacus, How. {I. c. p. 268). 

 [Howard's record of his Isodromus iceryce (Pieport Ent. U. S. 

 Agric. 1886, p. 488) is an error, the species having been raised 

 from the Neuropterous genus Chrysopa {cf. Ashm. 1900, p. 378.)] 



88. Icerya rosce, Riley.* 

 From a host of this name Ashmead records Cerchysius iceryce, 

 How. — distinct from the last-named Chalcid — from Northern 

 America (Ash. 1900, p. 380). [Dalla Torre (Cat. v. 415) gives 

 Lestophonus iceryce as hemipterous host of Euryischia lestophoni, 

 Koebele ; Scudder knew no such genus, but cf. Kiley, Report 

 Ent. U. S. Agric. 1889, p. 92.] 



89, Lichtensia koehelei, Mask. 

 Two enemies have been bred from this species in Ceylon. 

 Both Aphycus lichtensite and Encyrtus {Microterys) lichtensice, 

 Howard, are described in Proc. U. S. Nat. Mus. 1896, pp. 636 

 et 640. 



90. Lichtensia viburni, Sign. 

 Two specimens of a Coccophagus sp. were bred at Llandaff 

 from this Coccid, and Newstead suggests (Mon. Cocc. Brit. i. 31) 

 that, since L. viburni is seldom attacked, the parasite is probably 

 rare. It is improbably exclusive.
