advantage of using a ring of thick card, whicli jou mention in your note. Tlie 

 specimens I saw are very 'well preserved, though several years old. — F. Katteb,

Lepidoptera of Yorkshire. — At a meeting of the Entomological section of the 

 Yorkshire Naturalists' Union, held at Leeds, on January 11th, it was decided to 

 publish a list with localities of the Lepidoptera of the county of Yorkshire. Its 

 compilation was placed in the hands of Mr. W. Prest, of York, and myself. May I 

 ask, therefore, that every Lepidopterist who has collected in any part of Yorkshire 

 will kindly send list with localities (and, in the case of rare species, dates) of all the 

 species noticed, with any notes that may be of use, to me, as early as convenient. I 

 need scarcely say that all such assistance shall be fully acknowledged. — GrEO. T. 

 PORBITT, Highroyd House, Huddersfield : January, 1879. 



On the power of resisting intense cold possessed by Cheimatobia brumata. — At 

 the meeting of the Entomological Society of London, held on the 4th January, 1875 

 (vide Ent. Mo. Mag., xi, p. 213), I called attention to the appearance of quantities 

 of this moth immediately after the breaking up of a severe frost, and asked if they 

 were recently emerged or not, a point upon which there appeared to be difference of 

 opinion. The question has again occurred to me. Last night witnessed a sudden 

 thaw after three weeks of nearly continuous frost, latterly of great severity, inasmuch 

 as the thermometer registered only 5° Fahrt. (= — 15° Centigrade) on the night of 

 the 24th inst. To-night, C. brumata is flying to the light as lively as if nothing had 

 occurred. The earth is still frozen, excepting on the surface, so T think it impossible 

 that the moths can have only just emerged from the pupse, and it follows that they 

 must have existed in the perfect state through the frost ; it would hardly be proper 

 to say " lived," for they could not have been otherwise than frozen. It would be 

 an interesting experiment to test the greatest amount of cold this little moth can 

 bear without losing its power of re-vivifying. — R. McLachlan, Lewisham : 26th 

 December, 1878. 



The autumnal pupation of Abraxas grosstilariata. — In connection with the 

 note of Mr. Silcock on this subject (p. 150 ante), I may record, that in October last, 

 seeing some currant and gooseberry bushes were being defoliated, I beat out of 

 them a great many laiTse of A. grossulariata, and was surprised at the great size to 

 which many of these had attained, the others being of the small dimensions usual 

 at that season. To-day, I disturbed one of the larvss which had escaped my raid, 

 from its I'etreat under a loose piece of the bark of an apple tree overhanging a 

 currant bush ; it was more than half-an-inch in length, and, although there is hard 

 frost, it was lively, and swung itself down by a silken thread. Close by, under the 

 shelter of a horizontal branch, there are several pupse alive, suspended in their ordi- 

 nary slight hammocks. — -J. W. DouaLAS, 8, Beaufort Gardens, Lewisham : Zth

Variety of the larvm of Abraxas grossulariata. — Mr. Porritt, making his state- 

 ment respecting these larvae at second hand, has fallen into one or two slight errors 

 that are better corrected at once. First, the larvfe do not occur here, but in
