examples of British caught Colias croceus (edusa), one having helace 
fore wings and normal hind wings, the other the right side helice, 
the left normal, and a g right side ¢, left 9 form of Huchloé 
cardamines from Epping. Forest.—Prof. E. B. Poulton, F.R.S., 
brought for exhibition an example of marked irregularity in the 
colour adjustment of a Pier’s rape pupa to its surroundings; also 
the wings of the dragonfly -schna grandis left by a sparrow which 
had attacked the dragonfly and eaten the body.—In the absence of 
the author, Prof. Poulton then read a paper by Dr. R. C. L. Perkins 
on “ Variation in Andrena rose and Andrena trimerana,’ illustrated 
by a long series of examples of both species—Mr. G. T. Bethune- 
Baker exhibited specimens of Lycening from Provence (France) to 
show the large proportion of those more or less leaden coloured taken 
in the summer of 1920. The scales seen under the microscope were 
found to be in all cases of the kind ill developed—Mr. H. J. Turner 
exhibited an example of a Zygenid sent him by Mr. Greer from 
Tyrone suggesting a natural hybrid between Z. lonicere and Z. 
filipendule; also series of the large form of Z. filipendule occurring 
abundantly on Box Hill, in which the sixth spot was very weak, and 
the first to disappear from wear, together with an example of Z. 
anceps recently described by M. Charles Oberthur from Hyéres and 
a short series of trzfoliz albvana, Obthr., from the same locality.—Mr. 
G. T. Talbot brought a number of specimens of Huple@a from the 
Joicey Collection illustrating-a supposed black and white mimetic 
combination in the Tenimber Islands, Fiji, and Australia; and a 
white-banded group in the Key and Aru Islands.—Mr. R. Adkin 
exhibited an example of Margarodes wnionalis taken at sugar near 
' Arlington, Sussex, a native of southern countries, and probably a 
migrant to our shores.—Mr. H. J. Donisthorpe exhibited strings of the 
so-called “ ground pearls,’ being probably a Margarodes sp., M. formi- 
carum, Guilding, from Jamaica, and two examples of a species of 
Cionus new to science, swept near Lake Windermere a few years 
since by the Rey. Canon Theodore Wood.—Mr. W. J. Pendlebury 
showed an unusually dark form of the Carabid beetle Anchomenus 
dorsalis taken in Brecon, and a variety of the mosquito Theobaldia 
annulata, first found in Mesopotamia, and described by Capt. Barraud, 
R.A.M.C., the specimen exhibited being from Earl’s Court, October 
27th, 1920, and given the varietal name (in MS.) of swbochrea, 
Edwards.—Mr. W. G. Sheldon exhibited a series of 243 bred speci- 
mens of Peronia hastiana, L., from Sutherlandshire, Wicken Fen, the 
Isle of Wight and the coast of Lancashire. The series included 
most of the named forms, and a number of unnamed forms.—Dr. K. 
Jordan exhibited Misurgina leta from Madagascar, remarkable for 
its very strongly clavate antenna and the development of a stridula- 
ting organ. He compared the process with that occurring in other 
species of Agaristide and Noctuide. He said that Mrsurgina 
recalled Pemphigostola, Strand (1909), placed by the author with the 
Castnaida@, but which would on re-examinination probably turn out 
to be an Agarastid also.—The following papers were read : ‘‘ Notes on
