In the rtahoit^i-i series, Mel. hruneri Scudd., a new species of about the size and 

 general appearance of Md. femnr-rubrnm but the male with •i, strongly upturned, apically 

 broad subgenital plate occurs in Alberta at Fort McLood, and extends from there south- 

 ward to Nebraska and Colorado, and westward to Washington. 



But it is in the Spretus series that the largest number of Canadian species appear. 

 Most of them are closely allied to Mel. atlaiiis. Here are, first, Jlfel. Alashmns Scudd., a 

 new species found in Alaska and taken also at Spilmacheen, British Columbia ; next, 

 Mel. a finis Brun., another new species found in British Columbia, Washington, Utah and 

 Wyoming ; then, Mel. bilifuratxs (Walk.,) a CDmmon species on Vancouver Island, as well 

 as on the mainland in British Columbia, and over the border in W'ashington, Oregon, 

 Nevada and JNIontana ; Mfl. atlanis (Riley,) an extremely abundant insect, occurring 

 throughout the breadth of Canada, from Sable Island, off Nova Scotia, to Vancouver ; 

 it extends northward to the Yukon river in the west, though in the east f have only seen 

 or heard of it as far north as Quebec, Ottawa, Sudbury and Lake Winnipeg ; and linally, 

 Mel. sp7-etus (Uhl.,) the Rocky Mountain Locust, the arch- destroyer, whose home is in the 

 high plateaux of the Rocky Mountains and their eastern versant as far north as the 

 Saskatchewan, and which now and again ravages the country to the east by its migrating 

 hordes. 



In the Diucsoni series there are two Canadian species : Mel, Daiosoni (Scudd.,) which 

 occurs in Canada from Manitoba to Alberta, and has two forms, long-winged and short- 

 winged. Only the latter has been found in Canada, and the species ranges to New 

 Mexico. The other Canadian species is Mel. Gladstoni Brun., which has been found at 

 Medicine Hat in Assiniboia, and southward to Nebraska. Both these species are small 

 and inconspicuous. 



In the Fasciatus series are also two Canadian species : Mel. fasciatns (Walk.,) wide- 

 spread in Canada, having been rejiorted or sren by me from Newfoundland, Labrador 

 north of the Straits of Belle Isle, Anticosti, Hudson IJay, Lake of the Woods, Manitoba, 

 Saskatchewan, Assiniboia, Alberta and Alaska. It also occurs in the United States 

 everywhere near the Canadian border, from ocean to ocean, and as far south as New 

 Jersey, Missouri and Colorado. It again is dimorj>hic, but the wings in thebrachypterous 

 form are not very short, and the full-winged form is known only from Michigan. The 

 second species of this group is the only Canadian species not found in the United States, 

 Mel. borealis (Fieh.) I have seen it only from the barren grounds of northern Labrador, 

 but it is also reported from Hudson Bay and Greenland. It has slightly abbreviated 

 organs of flight. 



In the Femur ruhrum series the well known ]\fel. femnrrubrum (DeGeer), Fig. 33 occurs 

 over nearly the whole of Canada, from ocean to ocean, wanting only in some northernmost 



localities, such as Labrador ; and a second species, Aid. 

 extremus (Walk.), ranges from Quebec to the Yukon and 

 is dimorphic, though the organ? are half as long as the 

 body in the brachypterous type. The macropterous form 

 seems to affect high altitudes or latitudes. I have seen 

 specimens from the Alpine districts of the White Moun- 

 tains and from Arctic America, among other places. 



In the Angustipennis series the only Canadian species is Mel. coccineipes Scudd., 

 a new species of moderately large size, found not uncommonly in Nebraska, Kansas, Colo- 

 rado and Utah, and of which I took some specimens in company with Mr. Fletcher, at 

 Nepigon, Lake Superior. 



Mel. packardii Scudd., is the only Canadian species of the Packardii series, but this 

 occurs abundantly from Assiniboia to British Columbia. South of the border it occurs 

 over most of the United States west of the 100th meridian. 



In the CoUinus series, where all the males have forked cerci, there are several Can- 

 adian species ; Mel. alpinus Brun., a very small new species, which ranges from Alberta 

 to British Columbia, and is also known Irom Idaho ; Mel. infantilis Scudd., a still smaller 

 form, ori<Tinally described from Colorado, but found also in Assiniboia (Medicine Hat),
