62 THE ENTOMOLOGIST. 



59. Lecanium hemisphcericum, Targ. 

 Gaulle gives three parasites upon this species : Aphelinus 

 scutellaris, Dalm., Phcenodiscus cBiiens, Dalm., and Cerapterocerus 

 'pilicornis, Thorns. 



60. Lecanium rohiniarum, Dougl.* 

 From this species Aphelinus scutellaris, Dalm. {pulchellatus, 

 Westw.) is also instanced by Gaulle (Cat. 106). 



61. Lecanium quercus, Linn. 

 The host of Ratzeburg's Eulophus leptoneuros seems dubious. 

 He says : "I bred seven males and two females from Coccus 

 quercus on oak, in company with several E. pachyneuros " (Ichn. 

 d. Forst. i. 169 ; with four females of the latter species, cf. i. 

 167) ; later he adds that the former was bred " by Hr. Ndrdlinger 

 from beech -leaf galls. Hr. Wissmann bred it from Cynips 

 facunclatrix" {I. c. ii. 170), and {I.e. iii. 214) "again from 

 foecundatrix, and then from eglaiiterice." Mayr bred (Verh. z.-b. 

 Ges. 1875, p. 706) Microterys chalcostomus, Dalm., from this 

 species in Austria. And Gaulle (Cat. pp. 97-99) says Erycydnus 

 longicornis, Dalm., and Chiloneurus elegans, Dalm., have both 

 emerged from Lecanium on oak. Nees (ii. 434) quotes Fons- 

 colombe (Ann. Soc. France, 1832, p. 334) in saying tha,tEncyrtus 

 scutellaris, Dulrn., emerged "E cocco tihctorio Quercus cocciferas, 

 Junio," but Gaulle (Cat. 97) gives Eucomys obscura, Dalm., as 

 attacking Coccids on Quercus tinctoria. 



62. Lecanium eriophornm.* 



Aphycus apicalisy Dalm., is said by Gaulle (Cat. 99) to have 

 been bred from a species, which he designates as above. 



63. Lecanium coryli, Linn. 



Nees says of Encyrtus scutellaris, Dalm. [=.E. injidus, Rossi] 

 (Mon. Pterom. 223) : "Habitat in Coccis, pr^sertim Coryli Avel- 

 lanfe"; quoted by Curtis (Brit. Ent. fol. 395). Cldloneurus 

 formosus, Boh., is recorded from Coccus coryli by Thomson (Hym. 

 Scand. iv. 149). Mayr (Verh. z.-b. Ges. 1875, p. 706) also bred 

 Microterys sylvius, Dalm., from Lecanium coryli, in Austria, and 

 is quoted by Gaulle and Ashmead. From the var. L. corni, 

 Bche., Mayr also records [I. c. 696) Aphycus punctipes, Dalm. 



64. Lecanium piperis, Green.* 

 - This species is said to be attacked by Encyrtus flavus, Howard 

 (Rep. Ent. U. S. Agric. 1881, p. 367). 



65. Saissetia olece, Bern. 

 Lecanium olece is the host of Tomocera californica, Comst. 

 (Rep. Ent. U. S. Agric. 1881, p. 368) in America, and of Apycus 

 lounsburyi, How. (Ashm. 1900, p. 387) in South Africa.
