338 THE CANADIAN ENTOMOLOGIST. 



Measurements of ^ : Length of body, 25 mm.; of pronotum, 6.7 mm.: 

 of hind femora, 19 mm.; of tegmina, 34 mm. 



I found four males of this species at Sarnia, on the 12th of August, 

 T901, by tracing the song to its source. The song was a loud, penetrating, 

 continuous whirr, quite suggestive of the dog-day Cicada, but less clear, 

 and very unlike that of ensiger. It was heard in the morning during 

 bright sunlight. 



The specimens were taken in a large stretch of open grassy marsh 

 land, bordering the St. Clair River. Earlier in the season this area of land 

 had been entirely covered by water, but the ground was dry when I visited 

 the spot.

This is much the most abundant locustid found in Ontario, and is 

 common in every part where I have made collections of Orthoptera. It is 

 especially numerous in low damp pastures, timothy and clover meadows. 



My earliest captures are dated July 25th, but the imagoes usually 

 appear rather before this. They remain until the beginning of October. 



The song of the male is somewhat like a faint echo of that of 

 Orc/te/iftitnii vJilgare,hwt the "2// "is emitted only once or twice at a 

 time, and at shorter intervals, "■ xr zip, zip, xr " 



Fasciatum is one of the few common locustids in northern Ontario. 

 It is as abundant at North Bay, Lake Nipissing, as at Point Pelee, and 

 south of the boimdary line its range extends to Buenos Ay res, S. A.
