xcvi. PRESIDENT'S ADDRESS. 



it seems to have been a good year for other migrants, notably 

 Vanessa Antiopa, the Camberwell Beauty. I also find a note 

 (E.M.M., XVII., 169), to the effect that in the New Forest the 

 spring specimens in 1880 were plentiful. It would seem likely 

 that many of them, at all events, had been bred in this country 

 and hibernated here. 



I have alluded to the occurrence of other species of insects at 

 great distances from land, and this has often happened with 

 regard to Lepidoptera. From a number of instances given by 

 Mr. Tutt I mention a few of the most striking. In a cyclone 

 200 miles from the Cape Verde Islands, a great number of birds 

 and butterflies, including many Vanessa Cardui and Hypolimnas 

 misippus, came on board the ship Whinfell. Lucas records that, 

 when 1,000 miles from Brazil, a number of moths of perhaps a 

 dozen species came on board his ship, and there are numerous 

 other records of a similar nature where several species are 

 involved, which seem of a different class to those in which a 

 swarm of one species only was seen. The Pleione, when 

 440 miles from the nearest point of the American coast, was 

 surrounded by an immense swarm of Deiopeia pulchella a weak- 

 flying moth which occasionally visits this country. Hypolimnas 

 misippus was seen in great numbers by Captain Ellis in May, 

 1893, more than 500 miles from land in the Atlantic. Though, 

 as we have seen, considerable migrations take place to our own 

 shores, yet they seem to be of no importance compared with 

 those that occur in other parts of the world. 



In North America large migrations take place, but apparently 

 not to the same extent as in the southern half of the Continent. 

 One of the most striking was noticed in Bermuda on October ist, 

 1874, when a cloud was seen approaching from the north-west, 

 which was discovered when it reached the shore to consist of an 

 immense swarm of a small yellow butterfly, Eurema lisa, which 

 must have travelled across the sea for at least 600 miles from 

 America. The fishermen near the island reported that the
