species withheld until the revision of this genus, which Mr. J. A. G. Relin 

 has in hand, is completed, and it is possible to give accurate specific 

 determinations. The genus Xanthippus also needs further study, and 

 more collecting done, before a complete enumeration of the Bi-itish Col- 

 iimbia sijecies is possible.

 Locust. 



Thomas, Cyrus. Proc. Acad. Nat. Sci., Philad.. p. 82 (1870). 



A common insect in late summer and fall in the British Columbia

Camnula pellucida Scudder, 1862. The Clear-winged Locust. 



Scudder, Samuel H. Jour. Bost. Soe. Nat. Hist., VII, p. 427 (1862). 



This species is one of our most injurious Canadian Locusts, and has 

 caused more damage in British Columbia than any other species. It 

 occurs from time to time in the form of serious outbreaks often covering 

 many hundreds of square miles and the insects are so abundant that the 

 native vegetation and cultivated crops are almost entirely destroyed in 

 the infested areas. One of the most injurious habits that this locust has 

 in British Columbia is that of concentrating upon the cattle ranges and 

 destroying the feed of the cattle to such an extent that serious loss often 

 occurs.
