_ On the Nochta extrema, o/ Hubner. -Last summer when I met Dr. Staudinf 
in Viemia, he was on his way to Pesth, a locality I had some thoughts of visiti 
myself, but my friend, Dr. C. A. Dohrn, of Stettin, dissuaded me. Unfortunate 
a Coleoptenst is not a good guide for a Lepidopterist, and I found out afterward 
had made a great mistake in not going to Pesth, and have resolved to be wiser m 
time. 
After Dr. Staudinger had been to Pesth, I saw him both at Prague on his w 
home and again at Dresden after he had reached home, and he was veiy full of wl 
he had seen at Pesth-the National Museum there containing the original collectic 
of Ochsenheimer and Treitschke. The former had been at first placed on t 
ground floor, with this unfortunate result that in 1838, on the occasion of an v 
usual flood, it was for nearly two days under water ! However, Dr. Standing 
assured me there were many interesting things to be seen in both coUections a 
that he had made several notes with reference to the synonymy of some obscu 
species, and that he would shortly pubHsh an article on the extrema of Hiibn. 
This article, which I have been anxiously expecting for nearly a twelvemonth h 
appeared in the first portion of the Stettin. Entomologische Zeitung for 1869 at 
85 (though omitted in the list of contents of that number). As I apprehend tl 
may interest many English readers, I append a translation of the article. 
" Tapinostola extrema, Hb., fio- 412. 
"That we have had this somewhat puzzling species standing in our collectio 
under another name had long been tolerably evident to me. Hiibner's figure 4 
must, at any rate, have been made from an abnormal specimen, since a perfect 
white Noctua with black cilia to the anterior wings has probably never been foun, 
It was just possible that the English Noctua Bondii might be the true extrema 
Hubner ; smce that species in the coloration and spots of the anterior wings agre. 
very fairly with Hiibner's figure, and sometimes shows even a dark shade btfol 
the ciHa, which the colourer might by mistake have transferred to the pale cil, 
themselves. But since, according to Treitschke, v. ii., p. 315, Hiibner's extrev 
has lately been added to nearly all the larger collections from the neighbourhoo. 
of the Rhine and the Main, and Bondii has hitherto only been taken in the Sou, 
of England and on Mount Parnassus, it became highly improbable, independently . 
Its slighter form, that it could be the extrema of Hiibner. According to this statl 
ment made by Treitschke it was evident that this extrema must be a speci. 
occurring with us in Germany, and probably existing in our larger collections 
Now Guenee has in the 1st volume of his Noctua, at p. 103, described a ne 
speces from England, which in my catalogue of 1861, at p. 46, 1 refen-ed to e^trem. 
Hb., but without assigning any reason for this step, nor at that time indeed coul 
I have done so, so that the union of the two, especially considering Hiibner's fij 
412 must have appeared veiy venturesome. Guenee, in good truth, looking j 
Hubner's figure, could not suspect in it his English species, and therefore describe
