Eric Shaw exhibited some II mimcli ma si/riiit/aria larva) full fed, also a

Spilote i • ltoss i ' lari at a, Exhibit and Discussion.- — Mr. J. A. Clark, 
many fine aberrations of S/iilutr t/mssulariata ; Mr. C. P. Pickett, a 
cabinet drawer full of S. i/mssnlariata ; Mr. A. W. Mera, also a large 
number of the same species, with several fair aberrations, chiefly with 
a darkening tendency. Mr. Mera observed that it was frequently 
noticeable that the northern forms of this species showed the darken¬ 
ing on the margins, while southern, and particularly those specimens 
from north London, had the central portion of the wing dark. Mr. 
Riches and Mr. Nicholson also exhibited this species, the latter ob¬ 
serving that larva-* found wild in the open country were always pale, 
while those found in gardens were generally dark. The imagines were, 
however, the same from both. Mr. Prout said be had found that 
larva; from the country were generally later. Mr. Mera was strongly 
of opinion that the colouring in the larva; of this species was not an 
hereditary trait. He further called attention to the fact that he had 
found I‘acln/s Ix’tnlaria lame differently coloured in the same district 
on differently coloured tree stems. Mr. Kaye said there must be some 
other agency at work, as Mr. Merrifield had proved with I'a/alin 
inacliaon, that the larva, in changing to pupa, acted responsively to its 
environment. 
Living larva of Angerona puunaria. —Mr. C. P. Pickett, a living 
larva of Amjerona fir unaria.
