IN THE BRITISH ISLANDS. 119 



Vol. ii., p. 139. Tceniocampa incerta var. pallida, Lampa (=pallida, 

 Stdgr.). Dr. Staudinger seems to have paid but little attention to 

 already named forms in describing many of the varieties he has received 

 from Central Asia. Thus, although a whitish-grey form of incerta was 

 named pallida, in 1885, by Lampa, he described another pale form, ap- 

 parently identical with Lampa's pallida, in 1888, under the same name. 

 His name therefore will sink as a synonym. He writes of his var. 

 pattida : " The Central- Asiatic specimens of incerta, are very generally 

 so exceedingly pale and clear, as to merit a distinctive name. The fore 

 wings are light-grey, without any reddish or brown shading, the darker 

 markings tending more strongly to obsolescence, than in the European 

 type form. The hind wings also are almost entirely light whitish-grey. 

 I obtained such specimens in number from Margelan (found in the 

 commencement of March), also from Kuldja and the Alexander Moun- 

 tains. From the latter locality (as I am informed), I also received quite 

 typical incerta, which, I suppose were most likely taken in the higher 

 region, so that the pale specimens apparently represent the form 

 (Steppen-form) from the lower lying country " (* Stettiner ent. Zeitung,' 

 1887, vol. xlix., p. 32). 



Tceniocampa, Gn., opima, Hb. 



Vol. ii., p. 143. Tceniocampa opima var. fuscus, Gregson. A num- 

 ber of undescribed varietal names are mentioned by Mr. Eobson as 

 being used in Mr. Gregson's cabinet, in ' The Young Naturalist,' vol. 

 ix., p. 122. Mr. Gregson seems to have had no idea of the type form 

 or to have looked up the literature on this species before naming these 

 varieties, with the result that the type appears to be called var. dis- 

 tinctce ; a form perhaps somewhere near my var. intermedia (but it is 

 pure guess work to place it) is called fuscatce ; a form not quite so 

 obsoletely marked as my var. grisea is called cinerce ; whilst the only 

 well-defined form, synonymous with my var. unicolor, " of an uni- 

 colorous dark brown colour with no band," he calls fuscus. Var. 

 unicolor, Tutt (< Brit. Noct.,' vol. ii., p. 143), therefore, becomes 

 fuscus, Gregs., Eobson (< Young Nat.,' 1888, p. 122). 



Tceniocampa, Gn., gracilis, Fab. 



Vol. ii., p. 145. Tceniocampa gracilis var. pallidior, Stdgr. 

 Another form described some 80 years ago by Haworth as sparsus, and 

 recently redescribed by Staudinger under the above name. Staudinger 

 writes : " Tceniocampa gracilis var. pallidior, Stdgr. In order to be 

 logical, I must bestow a suitable name on the form of gracilis received 

 from Kuldja, Margelan, and the Alexander-Gebirge (?), which is of 

 an entirely pale, ashy, or sand-grey colour. I possess also an almost 

 similar accidental aberration of gracilis from Denmark, as pale and light 

 as var. pallidior (the light Central-Asiatic local form) " (' Stettiner ento- 

 mologische Zeitung,' xlix., p. 32). This would appear to comprise also 

 Guenee's var. pallida, as Staudinger refers to sandy forms. At any 

 rate, his name has long been forestalled, owing to the pale form having 

 been long ago described under another name. 



Tceniocampa, Gn., gothica, Linn. 



Vol. ii., p. 149. Tceniocampa gothica. The variety called nigra by 

 Mr. Kobson in the ' Young Naturalist,' 1888, p. 121, appears to repre-
