type " (' Noctuelles,' vi., p. 94). Of H. glauca from Hoy, Mr. Gregson 

 writes : " Ordinary size and colour " (< Young Nat.,' vol. vi., p. 274). 

 Mr. Sydney Webb writes: "The colours which adorn the stone- 

 coloured wings of glauca are grey-brown, green-brown, ochreous and 

 pale violet, which combine variously in different individuals. I have 

 a specimen dark, with the exception of the hind margin which is paler, 

 and another is entirely of the blackish hue of Viminia rumicis " (in Hit.), 

 probably var. aperta, Hb.-Gey. 



a. var. lappo, Dup. Duponchel's description is : " The superior 

 wings are of a greyish-black, lightly powdered with bluish, with the 

 two ordinary stigmata almost white but outlined in black. The clavi- 

 form of the same colour. There are three transverse lines, the first, 

 grey, dentate and parallel to the outer margin ; the two others, black,* 

 waved, and enclosing the before-mentioned stigmata. This NOCTUA 

 has been sent by M. Schonherr to M. le Comte Dejean under the name 

 of lappo. It had been called so because it had been found in Laponie " 

 (< Histoire Naturelle ' &c., vii., p. 255). I am indebted to Mr. Watts 

 for some specimens of this variety from Belfast, which are very pale 

 and ashy, compared with my long series of Yorkshire specimens, 

 although occasionally a specimen of the latter is much less bluish and 

 altogether more ashy and unicolorous than is usual. Guenee writes 

 of this : " A little smaller, paler, more ashy, and the markings clearly 

 developed ; the ordinary stigmata smaller, especially the orbicular, the 

 claviform clearly outlined and pupilled ; the subterminal line tinted 

 with ochreous " (' Noctuelles,' vi., p. 94). Guende adds : " This 

 description is made from the same specimen that served as the type 

 for Duponchel. It is certainly only glauca " (I.e.). Staudinger says : 

 " Smaller, more ashy ; scarcely deserves a name " (< Catalog,' p. 91). 

 Of lappo, Zetterstedt writes : " Alis anticis cinereo fusco nigroque 

 variis, strigis 3 dentatis distinctioribus nigris extus griseo marginatis, 

 maculis ordinariis parvis obsoletis cinerascentibus ; posticis cinereo- 

 griseis, fimbria tenui alba." " Hab. in Lapponia D. Schonherr, e 

 cujus museo pretioso specimen typicum mihi ad describendum beni- 

 gnissime fuit communicatum." " Ab H. groenlandica, cui maxime 

 similis, praeter magnitudinem forte nonnihil minorem, etiam alarum 

 anticarum strigis nigris griseo marginatis, nee totis albis, et harum 

 strigarum 2 interioribus fasciam efficientibus, minus dentatis et undu- 

 latis, marginal! tantum evidenter dentata, dignoscitur. Macula alarum 

 ordinaries valde obsolete vix discernendaB " (' Insecta Lapponica,' p. 

 939). 



P. var. quadripositd, Zett. This variety is thus described by 

 Zetterstedt : " Alis anticis cinereo fusco nigroque variis, striga ad 

 marginem posticum dentata alba intus nigro marginata, maculisque 

 disci quatuor rotundatis albido cinereis ; posticis fuscis. Sub nomine, 

 ' Noct. lappo var. ?, Noctua glauca ? Hiibn. PI. 57, fig. 410.' a D. 

 Schonherr missa." il Hab. Ut Lapponias incola a Cel. Schonherr 

 dubie communicata (Lapponia ?). Similis certe et affinis H. lapponi, 

 Dalm. ut et N. glaucce, Hiibn. ; sed ab ilia strigis alarum mediis vix 

 ullis, a N. glauca colore magis fusco, nee glauco, et ab utraque maculis 

 4 rotundatis per pares positis, exterioribus paullo majoribus, distingui-
