OCCURRENCE OF XYLOPHASIA ZOLLIKOFERI AT NORWICH. 213 
VIII. 
ON THE OCCURRENCE OF 
XYLOPHASIA ZOLLIKOFERI AT NORWICH. 
At the meeting of the Society held on January 31st, 1911, 
Mr. H. J. Thouless exhibited on behalf of Mr. A. Plunkett 
a specimen of Xylophasia zollikoferi, which is not only one 
of the rarest of British, but is actually one of the rarest of 
European moths. 
It was captured by Mr. Plunkett at Carrow, sitting under 
a large electric lamp, on September 4th, 1905, As the species 
is not mentioned in any accessible book dealing with the 
British moths it has only recently been identified. 
It is the fourth British specimen. The first was captured 
at Deal in October, 1867, and is now in the Doubleday 
collection in the Bethnal Green Museum. The second was 
taken near Aberdeen in September, 1871. The third near 
Middlesborough on September 26th, 1903, on sugar. The 
Norwich specimen is the fourth. A fifth has since occurred at 
Methley, near Leeds, on August 12th, 1910, when it was 
shaken from a bunch of withered leaves. 
Abroad it has occurred in extremely small numbers 
(generally solitary specimens) near Berlin and Dresden, in 
Switzerland, Bohemia, Galicia, Hungary, in the Ural District, 
and in Central Asia. 
The life history of this species appears to be absolutely 
unknown, as neither ova, larvae, nor pupae have been described.
