species, is given by Miiller in ' The Entomologist,' vol. v., p. 47. He 

 writes : " Xylina lambda of Fabricius, somniculosa of Hering, rubescens 

 of Menetries. Even to this day there stands in Treitschke's collection 

 the type of Noctua lambda of Fabricius (' Ent. Syst.', iii., 2, p. 106, 

 No. 317), a species which has been discussed at some length by 

 Treitschke (vol. iii., p. 18). This lambda of Fabricius is doubtless 

 identical with the subsequently described somniculosa of Hering 

 (' Stett. ent. Zeit.,' 1851, p. 165) or the still subsequent rubescens 

 (Menetries, ' Etud. Ent.,' 1859), as the specimen seemed to me to be a 

 sharper marked one. The Fabrician indication of the markings of the 

 fore wings : ' Lineola baseos duabusque in medio atris,' also applies 

 better to the sharper-marked variety rubescens of Menetries. I, there- 

 fore, believe that this lambda came originally from Lapland, whence it 

 is known that Herr Schneider of Stralsund, from whom Fabricius 

 received the specimen, often obtained collections, and where the 

 species is not scarce, although I regard this form, as Treitschke has 

 previously done, to be only a variety of zinckenii, yet as a well-defined 

 local form it must keep its name, and must now stand as :

Calocampa, St., exsoleta, Linn. 



Vol. iii., p. 108. Calocampa exsoleta var. impudica, Stdgr. This 

 variety was described by Dr. Staudinger as follows : " Calocampa 

 exoleta var. impudica, Stdgr. As long ago as 1882 (in p. 47 of this 

 journal), I mentioned the receipt of three specimens of a var. of exoleta 

 from Lepsa and Saisan. Since then, I have received the same in greater 

 numbers as a special local form from Margelan and Samarkand, where 

 they were found late in the autumn or hibernated in March. This var. 

 impudica has the same peculiarity of all other Central Asiatic forms, 

 namely, it is lighter in coloration than the European as well as less 

 pronounced in its markings. The fore wings are ashy-grey without a 

 brown tint mostly with striking lighter yellow-grey outer margin. All 

 the darker markings appear more suffused. The hind wings are also 

 lighter with paler almost white fringes. The underside is also coloured 

 lighter in comparison. The hind wings are here almost whitish with 

 darker dusted nervures. The black median spot is always present, but 

 the dark transverse line behind it is often entirely absent " (* Stettiner 

 entomologische Zeitung,' vol. xlviii., pp. 35-36). 



Heliothidce, Bdv. 



Vol. iii., p. 121. For "9. Family '.Heliothidce, Bdv.," read "10. 

 Family : Heliothidce, Bdv." 



Heliaca, H.-S., tenebrata, Sc. 



Vol. iii., p. 132. Heliaca tenebrata var. albescens, Ckll. On p. 

 132, I referred to a variety with white hind wings, which I said I 

 thought Mr. Cockerell had named albescens. Mr. Cockerell now points 

 out that the variety was named in ' The Entomologist,' 1889, p. 126, 

 under the synonym of H. arbuti.
