The present specimen was taken at Earl’s Court on October 
27, 1920, by the exhibitor. The variety has been given the 
manuscript name of subochrea by Mr. F. W. Edwards, to 
whom the exhibitor is indebted for the identification and 
details. 
Mr. Hy. J. Turner exhibited a specimen of Zygaena sent 
to him by Mr. Greer of Tyrone as a natural hybrid between 
Z. lonicerae and Z. filipendulae, taken on ground where the 
two species appear at the same time, and have occasionally 
been observed to copulate. A short series of the two species 
from the same locality were shown for comparison. The 
general coloration, shape of wing, margin of hind-wing, and 
underside coloration and marking tended towards lonicerae, 
while there were six spots, the sixth being decidedly feeble; 
the antennae were more like those of filipendulae and the size 
and shape of the spots were those of filipendulae. He also 
showed a sample illustrative of the large and very abundant 
colony of Z. filipendulae on the S8.E. of Box Hill, in which 
the sixth spot was almost invariably very weak and the first 
to disappear from wear, together with a specimen of Zygaena 
anceps recently described by M. Oberthiir from Hyéres, and 
a short series of the Hyeres race olbiana of Z. trifolii, which 
has also been named by M. Oberthiir. 
Mr. W. G. SHELDON exhibited a series of 243 bred specimens 
(1920) of Peronea hastiana L.: from Sutherlandshire, 126; 
Wicken Fen, 63; Isle of Wight, 26; and Lancashire Coast, 
28. These specimens were the whole of those bred in 1920, 
with the exception that of the Lancashire specimens about 
fifty more than those exhibited were bred; these were entirely 
a melanic form. The series includes most of the named forms 
and a number of unnamed ones. 
Dr. Jorpan exhibited Musurgina laeta, a new genus and 
species of Agaristidae from Madagascar, remarkable for its 
very strongly clavate antenna and the development of a 
stridulating organ. The fore-wing of the species, of which 
only the ¢ is known, is russet brown and bears a white stripe 
which runs from the base to the lower cell-angle and thence 
parallel with the termen to the costal margin, the hind-wing 
being orange, with a black terminal band. The stridulating
