LOCUSTS IN YOKKSHIRE : 

 with special eeference to the flight of i 876. 



By Wm. Denison Roebuck. 

 ( Goncluded.J 



During the same autumn (1869) anotlier species of locust, which 

 Mr. P. Walker first named P. migratorius^ with his usual care," and 

 afterwards corrected to P. cinerascens^ invaded the county of Aberdeen, 

 occurring all along the coast and as far west as Balmoral, where 

 large quantities were seen on the way to Loch-na-gar (W. C. Angus, 

 Entomologist^ April, 1870, v. 58.) 



Concurrently with these two simultaneous invasions by two 

 different species a couple of single examples occurred in Yorkshire. 

 One taken in Richmond was exhibited at a meeting of the Richmond 

 North Riding Naturalists' Field Club, Dec. 14, 1869 {Scientific Opinion, 

 Jan. 5, 1870, iii. 23). The other was taken by Mr. W. Elliott, 

 gardener, Queensbury, near Halifax, in his garden, at the end of 

 August or beginning of September {Newman^s Entom., April, 1870, v. 

 58). No name is assigned to either of these specimens, and it seems 

 to me, if they could be seen and examined, highly probable that we 

 should be able to add the name of Acridium peregrinum to our York- 

 shire fauna : seeing that they seem to approximate in distribution 

 more to the southern than to the northern invasion. 



1874. 



Mr. Charles Williams {Science Gossip, Feb., 1877, p. 21) states 

 that the villagers of Cheddar, in Somerset, reported to him that 

 large numbers visited their vicinity in 1874, committing havoc in 

 gardens, and that their description of appearance exactly tallies with 

 a specimen of Pachytylus migratorius, sent to him from Egypt. 



1875. 



The years 1870, 1, 2, 3, and 4 are devoid of any records, so far as 

 I can ascertain, and the whole of the specimens of 1875 were confined 

 to our own county of York. 



On the 5th July, Mr. B. Bagshawe, of Sheffield, picked one up 

 alive in High-street, the second he had caught in the same locality 

 {SJieffield Daily Telegraph, Tuesday, July 6th, 1875.) On the 11th 

 September a locust was found in a field below Clifton, near Brig- 

 N. S,, Vol. it., May, 1877.
