 This species is one of the earliest to appear in the spring, making 

 itself conspicuous on the wing by its bright yellow wings and rattling 

 stridulation. It is quite common about Toronto in open, sandy, unculti- 

 vated lands, especially where these are scattered with low bushes and 

 scrubby trees. I have never seen it about Lake Simcoe, though there are 

 spots there which would apparently make a suitable home for it. 



My earliest capture of the full-winged insect was on May i6th, 1896, 

 though it probably appears some days before that. 



I think it very probable that Arphia xatithoptera, Germ., is also 

 found in Ontario, but have not as yet seen a specimen from here.

 This is the first of our locusts, except the Tettigin^e, to make its 

 appearance in the spring. The young are sometimes extremely abundant 

 in the fall, but large numbers perish during the winter, and though oft^n
