ABSTRACT OF PROCEEDINGS. 



JANUARY ^th, 1896. 



T. W. Hall, Esq., F.E.S., President, in the Chair. 



Mr. F. Clarke, A.P.S., of Paddington Infirmary, was 

 elected a member. 



Mr. Carpenter exhibited a considerable number of Colzas 

 edusa, being a portion of a third brood. The parent was cap- 

 tured at Littlehampton on August 23rd, and laid 123 ova, of 

 which no less than 113 eventually produced imagines. He 

 stated that the last emergence was in the third week in 

 November. The species was an exceedingly easy one to

 open during November, on the south coast, whenever the 

 sun was sufficiently bright.

 being typical London forms from Wimbledon Common, and a

 He stated that the latter showed the whole range of the 

 variation of the species in Yorkshire from the banded 

 to dark brown or purplish forms, and that there was 

 only one spot in the neighbourhood of York where the 

 darkest specimens were obtainable. Very occasionally 

 a solitary melanic example was found elsewhere. At 

 Askham Bog none but light forms occurred ; at Sandburn 

 none but banded forms. In both districts the soil was 

 practically the same. Mr. Barrett said that the unicolorous 

 dark form was common around Huddersfield ; while at 

 Rotherham, which was more elevated ground, only the 

 clouded form was taken. Mr. South said that Bishop 

 Auckland was also a locality for the dark form. Mr. 

 Tunaley said that he had taken all the forms shown from 

 the neighbourhood of Birmingham, but that var. fuscata 

 was very local. On one bank, north-east of Birmingham, 

 fully exposed to the prevailing south-west wind, which
