59. Lecanium hemisphcei'iciim, Targ. .) 



Gaulle gives three parasites upon this species : Apheliniis 

 scutellaris, Dalm., Ph(snodiscus ceneus, Dalm., and Cerapterocerus 

 pilicornis, Thorns. 



60. Lecanium rohiniariim, Dougl.* 

 From this species Aphclimis scutellaris, Dalm. {pidchellatus, 

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



61. Lecanium querciis, hinn. 

 The host of Eatzeburg's Eulophus leptoneiiros seems dubious. 

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

 qaercus 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. Nordlinger 

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

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

 foecundatrix, and then from eglanterice.'' Mayr bred (Verb. 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 Cldloneurus elegans, Dalm., have both 

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

 colombe (Ann. Soc. France, 1832, p. 334) in saying that J5wc?yr^its 

 scutellaris, DoXm.., emerged "E cocco tinctorio Quercus cocciferse, 

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

 attacking Coccids on Quercus tinctoria. 



62. Lecanium eriop)}iorum.* 



Aphycus apicalis, 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. infidus, Rossi] 

 (Mon. Pterom. 223) : "Habitat in Coccis, prsesertim Coryli Avel- 

 lanse"; quoted by Curtis (Brit. Ent. fol. 395). Chiloneurus 

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

 Scand. iv. 149). Mayr (Verb. 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.e. 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 caUfornica, Comst. 

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

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