2756 Insects. 



in the place above cited, Illiger in his revision of the Wien. Verz. (two vols. 8vo. 1801), 

 nor Charpentier and Zinc-Somers in their remarks on the insects contained in the 

 Schieffermyller collection (1821), refer to either of the figures in question: in fact 

 Thunberg's insect is totally lost sight of by all subsequent writers to the present day, 

 excepting my reference thereto in the ' Systematic Catalogue,' in 1829, and Zetterstedt, 

 in his ' Fauna Lapponica,' in 1840. A few months previously to the publication of the 

 Catalogue I obtained from Weaver a pair of the insect in question, with uninterrupted 

 fascia? on the upper wings, as in Curtis's figure (pi. 100, 1826), and which I imme- 

 diately identified therewith : remembering, however, the figure and description in 

 Thunberg, I compared them with the insects, and should have been perfectly satisfied 

 with their identity had it not been for the integrity of the fascia? : hence I placed a ? 

 to the reference. Subsequently I have procured a series of the insect, which — like 

 the majority of the Tortricidae — is very variable, and am confirmed in my opinion 

 that they are identical with Thunberg's, which, moreover, is a northern species. 



Duponchel, in his vol xi. (vi. Nocturnes), t. 256, f. I, a, b (1834), introduces two 

 figures as the Peuziana of Hubner : one of these Guenee considers synonymous 

 therewith, and probably with tiifasciana of Fabricius ; the other he refers to his 

 Diurneana, which again is now supposed to be identical with bellana ; but in his 

 (Guenee's) definition of the upper wings the words " fusco, nigro, flaveoloque inductis " 

 occur, which last colour seems to cast a doubt upon the point. Curtis considers his 

 — or rather Haworth's MSS. — octomaculana (of which insect, till very recently, I had 

 only once had a casual view) as " considerably like, if not identical with, Hubner's 

 Penziana, t. 14, f. 85."— (Ann. and Mag. Nat. Hist. 1850, p. 112). 



This last fact sufficiently elucidates the difficulty of the subject; which is further 

 corroborated by Guenee saying, in reference to his Diurneana, " Cum Penziana 

 (Hubner's) confusa, Synonymiaque fere inextricabilis." 



From the above remarks the reader may be enabled to judge how far caprice in- 

 duced me to restore Thunberg's original name, applied in honour of his friend Pentz ; 

 the total neglect of which, by subsequent writers, has thus formed the basis of a fal- 

 laceous theory much more " destructive to science " than ignorance, a quality, as 

 above shown, not inapplicable to all parties ; which may be further illustrated by the 

 following list of Tortrices, extracted from the ' Insecta Suecica,' of which no subse- 

 quent writer — excepting, in part, Zetterstedt, in the work above noticed, in 1840 — 

 has taken notice.
