 cloud they appear like smoke. 



I do not ever remember to have seen 

 such swarms, except in the fens of the Isle 

 of Ely. They appear most over grass 

 grounds. White. 



APHIDES. 



On the 1st of August, about half an hour 

 after three in the afternoon, the people of 

 Selborne were suprised by a shower of 

 Aphides which fell in these parts. They 

 who were walking the streets at that time 

 found themselves covered with these in- 

 sects, which settled also on the trees and 

 gardens, and blackened all the vegetables 

 where they alighted. These armies, no 

 doubt, were then in a state of emigration* 

 and shifting their quarters ^ and might per- 

 haps come from the great hop-plantations 

 of Kent or Sussex, the wind being that 

 day at North. They were observed at the 

 same time at Farnham, and all along the 

 vale at Alton. . White.
