THE ENTOMOLOGIST. 163 
V. Polychloros, an insect which had not been taken here for 
‘fifteen years previously. In 1873 I sent you the intelligence 
of taking a V. Antiopa by myself, and six more by others, not 
taken for twenty years previously. This year I have the 
pleasing intelligence to transmit to your subscribers of the 
capture here of two beautiful specimens of the alder-moth 
(Acronycta Alni), both in first-class condition. This rare fly 
has not been seen in Doncaster for nearly thirty years. I was 
out collecting the larve of W-Album, in company with 
J. Jackson, Wm. Cook, and Mr. Talbot of Wakefield, on the 
30th of June, when one of the Alni was taken by Jackson, at 
rest, on the bole of a tree; the other was brushed out of the 
elm by Cook. This still shows the wonderful occurrence, 
that I should like some more experienced naturalist to 
clear up, how it is that insects reappear after an absence of 
a quarter of a century, and even longer periods.—J. Potts ; 
19, Senior Terrace, Doncaster, June 4, 1874. 
Acronycta Alni in Yorkshire-—On the 31st of May I had 
the pleasure of taking a beautiful specimen of Acronycta 
Alni at rest.—John Harrison ; 7, Victoria Bridge, Barnsley, 
June 17, 1874. 
Acronycta Alni in Yorkshire-—I captured a very fine 
specimen of Acronycta Alni in Deffer Wood, near Norton- 
thorpe, June 8th, about 8.30 P.M.: it was resting on the 
trunk of an oak-tree, about four feet from the ground.—/f. 
Dearnley; Nortonthorpe Post-office, near Huddersfield, 
June 23, 1874. 
Acronycta Alni near Doncaster.—On Tuesday, June 2nd, 
I took a fine male specimen of Acronycta Alni, at rest, in 
Edlenton Wood, Doncaster; and the woodman, Mr. Atkin- 
son, took a female for me on the 4th of June, at rest.—W. 
Cooke ; 10, Alma Place, Doncaster, June 22, 1874. 
Acronycta Alni and Asthena Blomeraria at Malvern.—\1 
have great pleasure in recording the capture of two fine 
specimens of Acronycta Alni at sugar: the first, on the 28th 
of May, a female; the second, on the 9th of June,a male. In 
1868 I took one specimen in the same wood, on the night of 
July 4th, and saw two others. I have also taken fine speci- 
mens of Asthena Blomeraria, by beating, this season, it being 
a scarce insect in this locality—W. Edwards; 1, Abbey 
Terrace, Great Malvern, June 20, 1874.
