shade, which in some cases almost obscured the white 
ground, and permitted a much greater amount of individual 
variation. 
Mr. West, of Greenwich, exhibited specimens of the 
Hemipteron Psallus alnicola, taken among alders at Lewis- 
ham, where it had been found many years ago by Mr. J. W. 
Douglas. 
Mr. McArthur exhibited specimens of Larentia salicata, 
taken in N. Devon, and remarked that they were smaller 
and darker than the usual form taken elsewhere. He also 
exhibited a second brood specimen of Smerinthus popult reared 
this year. 
Mr. Perks exhibited, on behalf of Mr. W. Rivers, a 
specimen of Anastatica hierochuntica, L. (“‘ rose of Jericho”’), 
from the Levant, a cruciferous plant of marked hygroscopic 
properties, the whole plant rolling up into a ball and uproot- 
ing itself in periods of drought, so that it may be carried 
from place to place by the wind, unrolling and taking root 
again as soon as moistened, and in this way also distributing 
its seeds.

Mr. R. ApDKIN, F.E.S., President, in the Chair. 
Mr. Spindler exhibited a most remarkable colour aberra- 
tion of Epinephele tithonus, in which the black had entirely 
disappeared even from the apical spot, while the usual 
fulvous was as deep as in the ordinary type. This was the 
more remarkable, as the experiments of Mr. Perry Coste 
showed that ail the reagents used by him did not affect the 
black without altering the fulvous colour. The specimen 
was taken at Luggershall, in Sussex, flying over a furze- 
field, (figured, ‘‘ Entom.” xxx., p:/253). 
Mr. South exhibited a few bred specimens of Sfzlosoma 
menthastrt, being the second generation descendants of 
Moray parents, and remarked upon the extremely dark 
ground colour of some of the examples. 
Mr. Turner exhibited bred specimens of Lasiocampa querct- 
folia from Cambridgeshire, and remarked upon their small 
size, although the larve from which they were produced 
appeared to be very large; a specimen of Mamestra abjecta, 
of an unusually grey form, taken under a clod of earth in 
the Gravesend marshes; a small specimen of a red form of 
Agyrotis tritici taken in Woolmer Forest in August; short 
series of under sides of Epinephele (Enodia) hyperanthus from
