30 THE ENTOMOLOGIST. 



49. Lecaniiim liriodcndri, Gmel.* 

 From the synonymous L. tupulifera, Hill, Howard records 

 Leiicodesmia typica (' Insect Life,' 1895, p. 404) and CoccopJiagus 

 flavosciitellum, Ashm. (Revis. p. 36). 



50. Lecaniiim caprece, Linn. 

 Eunotus cretaceus, Walk., is recorded from this species by 

 Gaulle (Cat. 103), who also mentions Chiloneurm elegans, Dalm., 

 from a Lecaniiim on Salix (p. 99). The synonymous L. tilice, 

 Linn., is recorded (l. c. 98) as host of Eiicumys ohscnra, Dalm., 

 and (p. 99) of Blastothrix sericea, Dalm., while Kawall adds 

 (Stett. Ent. Zeit. 1855, p. 231) Eucomys scutellata to its para- 

 sites, and Newstead has an interesting note " On the Alteration 

 in the Form of the Scales of Lecaniiim caused by Internal Para- 

 sites" (Ent. Month. Mag. 1892, p. 267). Both L. alni, Modeer, 

 and L. cescidi, Kollar, belong here; regarding the former, I am 

 only aware of Gaulle's record (Gat. 99) of Apliycm punctipes, 

 Dalm., from it, but the latter is freely parasitized by Microteiys 

 chalcostomiis, Dalm. (Mayr, Verb. z.-b. Ges, 1875, p. 706), M. 

 Sylvius [1. c.) and Blastothrix schonherri, Westw. (/. c. p. 699), to 

 which Ashmead (1900, p. 390) adds B. sericea, Dalm. {longi- 

 pennis, How.), a common species both in Europe and Northern 

 America. 



51. Lecaniiim hesperidiim, Linn. 



Gaulle states (Cat. 99) Blaatotlirix sericea, Dalm., preys upon 

 the " Orange Scale," while in America Howard has recorded 

 Eucomys bicolor and Encyrtus jiavus (Rep. Ent. U. S. Agric. 1881, 

 pp. 362-7), Perissopterus mexicanus, Coccophagus cogndtus, C. 

 Jiavoscutellum, Ashm., and C. lecanii. Smith, from it (Revis. 1895, 

 p. 33, &c.). Ashmead (1900, p. 360) adds Encyrtus bicolor. How., 

 from America, and Aphycus alberti. How., from New South Wales, 

 to the parasites of this species, which is abuudant in British 

 greenhouses. 



52. Lecanium aceris, Bche.* 



From the Coccus of Acei- platanoidcs, Dalla Torre gives 

 Eucomys scutellata, Swed. (c/. Kawall, Stett. Ent. Zeit. 1875, 

 p. 231). Ratzeburg records his Encyrtus atricollis from moths 

 (Ichn. d. Forst. i. 213), but later {I. c.iii. 190) from Coccus aceris, 

 whence he also states {I. c. ii. 149) that Hr. Bouche bred Cocco- 

 bius pallidiis. Rondani is also said by Dalla Torre to have reared 

 Encyrtus injidus, Rossi, from it, but without reference ; Gaulle 

 adds Apheliniis insidiator, Dalm. {obscurus, Westw.), A. scutel- 

 laris, Dalm., Eucomys scutellatiis, Swed., Sceptrophorus cyaneus, 

 Dalm., Microterys sylvius, Dalm., and Pachyiieiiron coccorum, 

 Linn. 



53. Lecanium pruni* 



Nees von Esenbeck writes of Encyrtus aruginosiis, Dalm.
