62 VARIETIES OP 



APPENDIX. 



During the progress of this work, I have been able to get the 

 original descriptions of some species which were not forthcoming at 

 the time those particular species were described. Certain articles 

 based on the variation of other species dealt with, have also been dis- 

 covered or recently written. It has been considered advisable to add 

 the references to such in the form of an Appendix. Notes also on 

 such a species as Catocala electa, only once captured in Britain, etc., 

 and not regularly included in the list of British species, are also 

 appended to this part of the work. 



ADDITIONS ETC., TO VOL. i. 

 Gonophora, Brd., derasa, L. 



Vol. i., p. 2. Gonophora derasa var. intermedia, Brern. The 

 original description of this variety is as follows : " It is of the pattern 

 of derasa, but the dentated line of the fore wings and all the other 

 markings better defined and more distinct. The ground colour of the 

 fore wings is very different and as grey as abrasa, Guen. from North 

 America, thus being without the golden yellow colour of the central 

 area found in derasa " (' Lepidop. Ost-Sibiriens, insjbesondere des 

 Amur Landes,' p. 46). 



Cymatophora, Tr., or, Fab. 



Vol. i., p. 3. Cymatophora or. Sven Lampa in the ' Entomolo- 

 gisk Tidskrift ' for 1885, p. 47, changes the name of this species to 

 ypsilon-grcecum, Goze, <Btr.' iii., 3, p. 253 (1781). 



Asphalia, Hb., flavicornis, Linn. 



Vol. i., p. 6. Asphalia flavicornis var. flnmarchica, Schoyen. 

 Sven. Lampa refers to Schoyen's variety as " morkare." It is described 

 and figured in the ' Eatomoiogisk Tidskrift,' 1881, p. 121, PL 1, figs. 

 3-4. This does not appear to be identical with my var. scotica, 

 although very near it, and it is another illustration of the similarity in 

 development between our Scotch and Scandinavian examples of certain 

 species, influenced as the fauna of both countries are by similar 

 meteorological conditions. 



Schoyen's original notice of the variety is as follows : " In my 

 review of ' The Arctic moths of Norway ' (p. 187), I have already 

 mentioned this form, from a very worn species received from 

 Sudvaranger, Ostfinmark, as Asphalia (n. sp. ?). Recently, I have re- 

 ceived from M. Sandberg, several specimens, quite fresh, which were 

 captured in June, 1880, at Kebbervick, near Klostervand in Sudvar- 

 anger, almost 70 North latitude, which have proved to be an excellent 

 dark Polar form of A. flavicornis. The figures are those of the darkest 

 specimens in my collection, and represent the extreme colour of the 

 Polar form. The others are less dark, although the lightest is darker 

 than the normal form. The markings of the fore wings are less distinct ; 

 in one specimen, the transverse lines are entirely absent, and in three 

 others, the greenish-yellow spot has also become invisible ; otherwise, 

 the colouring is like that of the normal form. That this species oc- 

 curred in the Polar region was mentioned by Dr. Tengstrom, who 

 states * Oatal. Lepid. Faun. Fenn. prac.', No. 200) that it also occurs 

 in Finnish Lapland, but does not mention its variation. In Scandi-
