118 VARIETIES OF NOCTTJJE 



apparently narrower winged and especially paler than baia. Even the 

 freshest specimens have the fore wings grey brown, and the hind wings 

 dull blackish-grey. The decidedly black dots in baia on the costa 

 (forming the short black mark characteristic of the species just before 

 the tip of the fore wings) are generally absent, and only rarely de- 

 veloped to the extent that they are in typical baia. The under surface, 

 thorax, and particularly the body, have never so reddish-brown a tint 

 as ordinary baia, but are of a pale greyish-yellow colour " (' Stettiner 

 entomologische Zeitung,' xlii., p. 411). Our British specimens of var. 

 grisea must run this very close, but they always (so far as I know) have 

 the small apical costal streak well-developed. 



Noctua, Linn., glareosa, Esp. 



Vol. ii., p. 108. Noctua glareosa var. hebraicaoides, Gregs. Mr. 

 Eobson in the ' Young Naturalist,' 1888, p 121, writes: "Var. 

 hebraicaoides of this collection (Gregson's) has a dark cold brown 

 ground colour, making the costal spots appear less distinctly defined, 

 and the margins of the stigmata more so." These North of England 

 dark forms seem to be very different to the Shetland var. suffusa, which 

 is of a rich dark brown. I do not recognise any form I have seen by 

 this description, and must assume that there is probably a second 

 melanic form independent of var. suffusa, occurring in certain localities 

 in the North of England. 



Noctua, Linn., conflua, Tr. 



Vol. ii., p. 123. Noctua conflua var. diducta, Zett. The Scandi- 

 navian description given by Lampa of this variety reads as follows : 

 "The fore wings are greyish-yellow with indistinct markings, the 

 pyramidal spot scarcely visible. The type specimen is in the Svenska 

 Museum, 1 ' etc. ( Entomologisk Tidskrift,' 1885, p. 53). 



Noctua, Linn., xantographa, Fab. 



Vol. ii., p. 124. Noctua xanthographa var. elutior, Alph. This 

 variety is mentioned in the ' Zoological Kecord,' 1889 (Insecta), p. 248, 

 as figured in PI. vi., fig. 3, of Komanoff's ' Memoires sur les Lepi- 

 dopteres,' vol. v. I find it also referred to in the ' Zoological Kecord,' 

 for 1887, as published by Alpheraky in the ' Stettiner ent. Zeitung,' 

 vol. xlviii., p. 168. This original description is as follows : " $ . 37 

 mm. Varietas major, alis latioribus, anticis (cum thorace) pallide- 

 cinnamo(n)eis, macula reniformi albido-circumscripta ; posticse cum 

 ciliis albidse ad marginem sordide grisescentes ; subtus alas omnes 

 pallidiores. Taschkent " (' Stettiner entomologische Zeitung,' 1887, 

 vol. xlviii., p. 168). 



Noctua, Linn., plecta, Linn. 



Vol. ii., p. 127. Noctua plecta var. anderssoni, Lampa. The 

 Scandinavian description of this variety reads as follows : " The fore 

 wings dark violet- brown, nearly violet-black, only the median nervure 

 at the base, and the borders of the stigmata yellowish-white." " Many 

 examples found by Andersson" (' Entomologisk Tidskrift,' 1885, p. 

 54). 



Tceniocampa, Gn., instdbilis, Fab. (incerta, Hufn.). 

 Vol. ii., p. 136. Taniocampa instabilis (incerta). Mr. Cockerell 

 writes : " Tceniocampa incerta, Hufn. is American, and has a synonym 

 alia, Guen. It also has a var. conjiuens, Morr." (in litt.).
