NOTES OX BRITISH TORTRICES.

 {continued from J). 31). 



Sn'icoris mlcana, Hiibn., Frol. — Dr. Wocke changes thla to oli- 

 vana, Tr., but wherefore I cannot understand, for though he ap- 

 pends a ? to his reference to Ililbner, he does not to Frolich, and 

 his name is evidently two years older than that of Treitschke. I 

 think, therefore, that micana, Frol., may safely be retained as the 

 name of this species. An allied species, to which Treitschke gave the 

 name of micana, is now altered to stihiana, Grn. 



Set'icoris alternana, Wilk. (Curt. ?). — I do not think that this 

 name can be assigned to Curtis. His description, as quoted by 

 Stephens, is not applicable, or rather is more applicable to irriguana, 

 or the dull, dark olive form of lacunana, which occurs along with alter- 

 nana in Scotland. Wilkinson's description, however, is excellent, and 

 his name must be the refei'ence appended to the species. Nevertheless, 

 Dr. Wocke has made a most extraordinary mistake respecting it. He 

 calls it ahernyiLLX, Wilk., and places it as a synonym of umhrosana, 

 Freyer, a species closely resembling urticana, but larger, and having 

 the horizontal pale streak in the dark fascia as in lacunana. From 

 this alternana is very distinct. Mr. Doubleday in his List calls it 

 Daleana, Dbld., on account of the existence of another alternana (or 

 rather alternella) in the genus Sciaphila, and a third in CocJii/lis, but 

 I see no fear of any confusion from the adoption of the same name in 

 such distinct genera, and as, moreover, there is no description or figure 

 appended to the name Daleana, I think it absolutely necessary to 

 retain Wilkinson's name. 



This species seems to be totally unknown on the Continent, but 

 the female resembles some of the forms of irriguana or metallicana 

 to some extent. 



Sericoris irriguana, H.-S. — Recorded as British by ]\Ir. Nicholas 

 Cooke (Ent. Mo. Mag., Vol. viii, p. 255), and noticed in the Ent. 

 Ann., 1872, under the name of metallicana, Hiibn., of which species 

 Dr. Wocke considers irriguana, H.-S., to be a variety. 



Of metallicana, Hiibn., Heincmann writes (Tortricina, p. 119) — 

 "Anterior wings olive-green dusted with bhickish, with two olive- 

 " yellowish fasciae, margined wilh lustrous (hiik yellow lines, the pos- 

 "terior fascia obli([ue, not forked. 



"This species has, amongst its allies, tlie hiMndcst anterior wings 

 '"with distinctly curved costa, and the hind margin not viry oblique.
