nympha pamphili^s, C. arcania (contrasted with the large var. 
instihricci from the N. Italian Alps); and Melanargia galatea 
(showing in the lowland specimens a strong tendency to 
obsolescence of the underside markings, in contrast to the 
somewhat strongly marked mountain forms). Besides these 
was a Pontia dapliclice $ from Home, showing distinct indica¬ 
tions of a black spot near the middle of the inner margin of 
each fore-wing on the upperside. 
Rare British Xylophasia.— Mr. J. W. Tutt brought for 
exhibition a fourth British example of Xylophasia zollikoferi 
sent him for determination, taken in September, 1905, at 
Norwich, by Mr. Plankett. He said he had dealt with 
the first two examples captured in Britain at length, in his 
“ British Noctuae and their Varieties,” i, p. 71. The first was 
captured in October 1867, by Mr. Harding at Deal; the 
second by Mr. Tait .at Inverurie, in September, 1871 ; the 
third by I\Ir. Lofthouse at Linthorpe, Middlesborough, Sep¬ 
tember 2nd, 1903. The first of these is in the Doubleday 
collection. The preceding British examples have been of the 
pale form (ab. pallida, Brit. Noct., i, p. 72). Mr. Plunkett’s 
example is of the remarkable radiate form, represented in 
Herrich-Schaffer’s “ Schmett. v. Europa,” Fig. 104. There 
are only half-a-dozen examples of this species in the British 
]\[useum Collection, all pale, and all males. The radiate form 
figured by Herrich-Schaffer is a $ , so also is Mr. Plunkett’s, 
and this suggests that the difference is sexual. It is really a 
very rare species—as rare on the Continent as in Britain, on 
this side of Hungary; getting more frequent in the Urals, and 
extending into Asia to Turkestan, but evidently nowhere com¬ 
mon, so far as is known. We have no knowledge of its life 
history. Several entomologists have remarked the superficial 
resemblance of the pale forms to Nonagria arundinis, and for 
this reason there may be others undetermined in British 
collections. 
Southern Forms op Agriades coridon. —Dr. T. A. Chap¬ 
man exhibited several cases containing series of Agriades cori- 
don, var. meridional is, Tutt, 6 { = constanti, Reverdin), and 
made the following remarks upon them ;— 
“It is probably accepted now that this form is double-brooded.
