Melanopliis cxtreinus, VV'alk., an allied species, will in all probability 

 be met with in Northern Ontario, as it has been reported from most of 

 the Northern United States, from Quebec, and various parts of arctic 

 and sub-arctic Canada.

I have found this insect in considerable numbers in the sandy tract 

 of land between Toronto and the Humber River. It frequents dry grassy 

 fields and sandy, bushy or thinly-wooded country. 



In most of the specimens from this locality the hind tibife are bluish- 

 green, though they may vary from a " robin's egg " blue to almost colour- 

 less or pale pink. Males with pink tibi* are seldom seen, these being 

 nearly always bluish-green or blue, or sometimes nearly colourless. Of 

 the females, about 25% have pink tibiae, and in about as many they are 

 glaucous or grayish. 



The adults appear much earlier than any other species of Melanoplus 

 found in Ontario, usually in early June. I took several $ 's on the 30th 

 of May, 1896; but these were all rather soft, evidently having been full- 

 fledged but a short time. I have never remained in the city long enough 

 in the summer months to ascertain how long in the season they remain, 

 the latest date upon which I have taken a specmien being July 21, when 

 they were still fresh and moderately plentiful. 



28. Melanoplus collinus, Scudder.

This dark-coloured locust is quite plentiful in Ontario in late summer, 

 although this is the first time it has been recorded from Canada. 



It frequents sandy or gravelly uplands, more or less open, or rocky, 

 unsettled country, such as characterizes the Laurentian area in Ontario. 

 During August, 1898, I found this locust extremely common along the 

 Severn River, which flows from Lake Couchiching, at the north end of 

 Lake Simcoe, to Georgian Bay through a somewhat hilly region of gneiss 

 and granite, near the southern boundary of the Laurentian area. Here 

 it was decidedly the most abundant grasshopper, far outnumbering any 

 other Melanoplus, and flew about the rocks and scanty soil in large 

 numbers. The specimens seen in this locality showed a wider range of
