 Dissosteira Carolina, Saiiss. Prod. (Ed., 137 (1884). 

 This large, well-known locust, easily recognized by its black wings 

 with a yellow border, is common everywhere in the settled parts of 

 Ontario, frequenting every dusty roadside during late summer and 

 autumn. It is our most striking species when on the wing on account of 

 its large size, ample wings, and peculiar, butterfly-like flight. 



It appears about the beginning of July, the earliest date on which I 

 have taken it being July 2, 1S96, and continues till October. I have seen 

 it at Rat Portage, the Muskoka District, DeGrassi Pt., Toronto, Hamilton, 

 and various other places in Southern Ontario which have not been 

 recorded.

 Spharagefnon aeqiiale, Comstock. Introd. to Entom., 103, 104 

 (1888). 

 This locust is quite common about Toronto on sandy soil. It is also 

 sometimes seen where the soil is clay, but much less frequently. I have 

 also taken it at Stony Lake, Peterborough Co., and have seen a specimen 

 taken at Sparrow Lake. 



The earliest date upon which J have taken it was June 24, 1896 

 (i (J). Its first appearance is generally, however, a little later, and it 

 continues to fly about until October. 



Its stridulation is a rapid and rather loud, rattling sound, resembling 

 that of Arphia siclphiirea. 



I should think it not improbable that other species of Spharagemon 

 occur in Ontario, since there are two others in New England, one of 

 which, S. saxatile, Morse, frequents rocky unsettled districts, such as 

 abound in the northern part of our Province.
