92 VARIETIES OF 



that in the dark rumicis, follows as a matter of course. In the same 

 way also the undersides of all the wings of turanica are paler, whilst 

 the dark central spot of the hind wings stands out distinctly. 

 Acronycta rumicis is one of the species, which, like so many others, 

 tends to become paler in Central Asia than in Europe " (' Stettiner 

 entomologische Zeitung, vol. xlix., p. 65). If this, therefore, be the 

 turanica mentioned in vol. i., p. 15 which was there referred on 

 Mr. Dobree's determination as a pale var. of menyanthidis, it would 

 appear that Dr. Staudinger and Mr. Dobree differ in opinion as to 

 which species turanica really belongs. I have never seen Central 

 Asiatic specimens, so cannot judge. That rumicis, however, is 

 occasionally of an almost pure white ground colour even in England 

 is certain, for I have long had a specimen in my cabinet which I was 

 unable to refer to either of our British species, but which I have now 

 practically determined to be rumicis. 



Viminia, Chpmn., albovenosa, Goze. 



Yol. i., p. 28. Viminia albovenosa. The original description of 

 this species is as follows : " Phalcena with filiform antenna?, with 

 robust, grey, tent-like wings, of which the nervures are of a whitish- 

 grey "(' Entomologische Beitrage,' iii., 3, p. 251). Werneburg also 

 refers the figure in De Geer's ' Memoires des Insectes,' ii., which 

 reference Goze quotes, to Borkhausen's venosa. 



Vol. i., p. 28. Viminia albovenosa. The American species known 

 as Arsilonche henrici, Grote, is probably identical with our species 

 albovenosa. This is also credited in Grote's ' Check List,' with two 

 varieties fumosum and evanidum. Of these Mr. Grote writes : " I saw 

 the type of ab. fumosum. It seemed to me to be a small, entirely smoky, 

 dark (almost black) accidental aberration. Whether our American 

 species is really identical or not with albovenosa, I do not positively 

 know. Evanidum, is the form in which the interspacal lines and dashes 

 are almost obliterated in the fore wings. Morrison says ' the most 

 common form.' Henrici has the streaky lines and dashes very plain. 

 Probably the two species are the same. Probably also henrici = degener, 

 and evanidum = type form, vide, Tutt, ' British Noctuee ' &c., vol. i., 

 p. 28" (MI litt., July, 1892). 



Vol. i., p. 28. V. albovenosa var. ochracea. I find that this dark 

 reddish-ochreous form belongs essentially to the brood which emerges 

 in the early spring, the great mass of this brood consisting, however, 

 of the typical form. Such a specimen would scarcely ever appear to 

 occur among the autumnal emergences. On the other hand var. 

 albida (var. argentea, Tutt), occurs only in the second brood, the great 

 mass of this latter emergence being of the form known as degener, 

 Hb. The species, therefore, shows decided seasonal variation, the 

 spring brood being more ochreous, the autumn brood, whiter in 

 tint. 



Vol. i., p. 28. Viminia albovenosa var. murina, Auriv. In the 

 1 Entomologisk Tidskrift,' for 1880, Professor Aurivillius described the 

 varieties of this species. His paper, at the time I wrote vol. i., of this 

 work, was quite unknown to me, and I find that I had been forestalled 

 in my var. argentea. The type he describes as var. ft, flavida (I.e. p. 

 3H), the latter name being sunk (as representing the type) in the 

 * Entomologisk Tidskrift ' for 1885, p. 48). His var. murina, however,
