" such wallis that I have chiefly found the imago flying." (Zool. Vol. IX., p. 
3101). Bearing this in view, is it possible— I will not say probiiblo— that there 
may be an instinctive feeling in this insect which leads it to settle on sunny walls 
in search of a plant whereon to deposit its eggs?— J. Gueene, Cubley Eoctory, 
Sudbury, Derby. 
*#* My query respecting M. stellatarmn was most fully and satisfactorily 
answered by Mr. Bond and Dr. Wallace at the meeting of the 4th February (vide 
ante p. 239). According to my experience, the walls, &c., especially frequented, are 
those that are the most free from any vegetable growths save the lowest forma of _ 
lichens. — R. McL. 
Notes on TapiTWstola (?) Bondii.—A short time since I sent specimens of this 
species to my kind friend Professor Zeller, and, in a letter received from him this 
moi-ning, he says — " After an examination of the figures and descriptions, I cannot 
" suppose it to be the extrema of Hiibner. Trcitschke (V. II., 316), who saw the 
" originals, says that the cilia, though too darkly coloured, are really dark, as if 
" singed, and adds that in the least marked specimens there is always a dark dot 
" in the outer (posterior or anterior ?) margin, which is visible on the underside. 
" Moreover, the whole underside is white, sparingly dusted in the intervals of the 
"prominent veins. I hope that when I am at Vienna I shall see the specimens in 
" the Museum, and be able to inform you of the real difference of these two species." 
I am rather surprised that these remarks of Treitschke were not quoted by 
Dr. Knaggs, as, if the specimens examined were the true extrema of Hiibner, it is 
quite cei'tain that Bondii is a distinct species. 
Lederer refers Herr. SchiifFer's figure 336 to Helmanni without any mark of 
doubt, and 337 to esoi/rema, Hub. ; but if the above-quoted remarks of Treitschke be 
correct, it cannot possibly represent this species. 
I believe it was taken from a female concolor, but I do not think this species 
has occurred on the Continent, unless the specimens which Lederer captured some 
years since in a marsh near Vienna were concolor. 
In July, 1843, I took several specimens of Nonagria {Tapinostola, Led.) con- 
color to Paris, and the late M. Pierret, to whom I gave them, said it was a species 
unknown to him, but was probably the extrema of Hiibner. 
In 1844 the late M. Becker had specimens from me, and as he sent many 
species which he procured in England to Herrich Schafier, I think it very probable 
that his figure 337 was taken from one of my specimens.— Hknry Doubleday, 
Epping, March lUh, 1867. 
On the habits of Acrolepia assectella, Z., a species not yet found in Britain. — 
Dr. Breyer gave an interesting notice of this insect in the sixth volume of the 
Annales de la Societe Entomologique Beige, (p. 21). 
" Our common onion. Allium cepa," says he, " is a biennial ; the first year pro- 
duces the onion, in the second we have the flower and the seeds. The flowers 
placed in an umbel are borne on a common stalk, which commences to shoot in the 
spring, flowers in June, and produces ripe seeds towards the end of September.
