ties since the end of June of noticing the gradual increase in 

 numbers of these species, and had seen about the beginning 

 of the month immense numbers, principally of P. rapes, on a 

 bed of Lavender growing in one of the Brighton squares. 

 He had not, however, heard of any unusual number of larvae 

 having been noticed in the Brighton district before the arrival 

 of the swarms of imagines, and it was possible that these last 

 were immigrants. The habit of drinking was not at all un- 

 common among Lepidoptera in hot countries. 



Mr. South said P. rapes had been unusually abundant in 

 his garden at St. John's Wood, and he had frequently seen 

 them on the watered roads of London. He quite agreed with 

 Mr. Carrington that the appearance of these species in such 

 numbers was to be attributed to immigration. 



Mr. T. W. Hall said he had noticed large numbers settling 

 in the moist ditches by the side of the railway at Ware. 



Mr. Step thought that some of the members would recol- 

 lect noticing on the occasion of the Society's excursion to 

 Bookham, in 1886, a nearly dry pool, the margins of which 

 were literally covered with bees drinking. Messrs. Wellman 

 and Tugwell and Dr. Rendall also mentioned having seen 

 great numbers of the two species of Pieris.
