386 Insects most injurious to Cultivators: — 



trees attributed to the appearance produced by an attack of 

 these insects, as upon any other tree. 



There are several species of moths which agree in their habits 

 of attacking the roses in the manner above mentioned : they 

 belong to the family Tortricidae, constituting the Linnsean section 

 Tortrix. Amongst them are to be mentioned especially, Lozo- 

 tse^nia rosana Linn., L. oporana Linn., L. nebulana Steph. 

 (rosana Haw.), and L. laevigana W. V. Of the last, Mr. 

 Stephens [Brit. Ent. Lepidoid., vol. iv. p. 74.) says that the 

 caterpillar feeds on the buds of the rose, despoiling them of 

 their beauty, and is very destructive in gardens. In his own 

 garden he found it a perfect pest, from the havoc its larva 

 created among the rose trees. Spilonota aquana [Steph., loc. cit., 

 p. 91.) is another rose-feeder, as Is also Dictyopteryx Forskaol- 

 edtia Linn., 8teph,, which is destructive to the centifolious roses, 

 according to Bouche. {Garten Ins., p. 112.) Spilonota cynos- 

 batella, according to Linnaeus, feeds upon the buds of the rose. 

 {Syst. Nat., p. 887.). I have, however, reared it from the leaves, 

 which it fastens together, forming a silken web between them, in 

 which it becomes a chrysalis. It is figured by De Geer [Memoires, 

 vol. i. pi. 34. fig. 5.). Pterophorus rhododactylus, also, accord- 

 ing to Fabricius, feeds on the roses ; and Antithesia salicella 

 Linn., Steph., is called the Provins-rose moth by Berkenhout 

 [St/n. Nat. H., vol. i. p. 147.), its caterpillar feeding on rose 

 leaves. 



The species which I have found most troublesome at Ham- 

 mersmith this year is the following; — 



Order, Lepidoptera LinncBus. (Powder, or scale, winged insects.) 



Section, Nocturna Latreille. (So named from flying by night, corresponding 



with the Linnsean genus Phalae^na.) 

 Family, Tortricidge Leach. (So named from the Linnaean section Tortrix, 



with which it nearly coiTesponds.) 

 Genus, Argyrotoza Stephens. (Generic name derived from a Greek word, 



signifying "decorated with a silver arch," from the markings of the wings.) 

 Species, Arg. BergmannzwHa Stephens. (Ca/., No. 7113. j Illustr. Brit. Ent. 



Lepid., vol. iv. p. 173.) Tortrix 'Bergnmnnidna Linn. (S^st. Nat., vol. ii. 



p. 878. ; Donovan's Brit, Ins., vol. v. pi. 157. f. 1 — 6. j Bouche Gart. Ins., 



p. 1 10. ; Haworth's Lep. Brit., p. 404.) 

 Syn., Tortrix rosana Hubn. Tortr., pi. 22. f. 137.) 



This beautiful little moth (^^.115, a, natural size;_^^,114.j^ 

 magnified) is thus described by Mr. Stephens: — "Anterior wings 

 yellow, clouded with fulvous, and obscurely reticulated with the 

 same ; with four slightly curved nearly equidistant streaks of 

 silvery dots ; the first abbreviated and near the base, the second 

 before the middle, the next rather behind, extending obliquely 

 to the anal angle, and the fourth on the hinder margin itself; 

 cilia pale yellow : posterior fuscous, with dirty yellow cilia. 

 Head and thorax sulphur-yellow. Extremely abundant in hedges
