A SWARM OF 

 BUTTERFLIES. 



By Johx E. Robsox. 



The occurrence of any insect in unusual 

 numbers is always a matter of interest to the 

 I Entomologist, even when the species are very 

 \ common. The Pieridj are known to have 

 ' the habit of sometimes appearing in immense 

 swarms, and as it does not fall to the lot of 

 | every one to witness the passage of one of 

 ; these migratory hordes, a few notes on the 

 passing of a flight of the Large White CPievis 

 brassier) that I once witnessed may be worth 

 printing. It was a line hot day in June, 

 there was scarcely any wind, and the atmos- 

 phere was unusually close and sultry. 

 Hartlepool stands almost on a neck of land 

 running into the sea, and there are scarcely 

 any gardens near it, or waste ground near 

 enough to make even White Butterflies 

 " common objects" in our streets. My atten- 

 tion was attracted soon after noon by an 

 ! unusual number of them flying past, five or 



six being visible at once, and as one passed j 

 | on, another appeared, so that the street was 

 j never clear of them. Children going to 

 I school were eagerly pursuing them, and 

 I creating quite a commotion by their shouts 

 about the " Loweys." These were but the 

 advanced guard, and the main body was yet ( 

 i to come. The butterflies rapidly increased 

 in number, until, instead of five or six being 

 visible at once, mauy hundreds even thousands ( 

 I were in sight, and the most unobservant were | 

 j attracted by the unwonted spectacle. They , 

 j flew very leisurely, yet seemed to have a [ 

 | special purpose in view, for they were all 

 going in one direction, towards the north- 

 west. They kept passing in such enormous 

 numbers that Mr. Darwin's expression, 

 " snowing butterflies," is the most appropriate
