and AlVjerta (Fort McLeod) ; and Mel. minor (Scudd. ), a tolerably common species in the 

 United States from Maine to the Rocky Mountains, and which was long ago sent from 

 Red River, Manitoba, by Robert Kennicott and Donald Gunn. 



Finally, in the Bivittatua series, where the species are large (the largest of those 

 found in Canada), we find Mel. femoratus (Burm.,) which ranges from Nova Scotia to 

 British Columbia, and extends as far north as Hudson Bay. In the United States it 

 extends southward nearly to the Ohio, and on the Atlantic coast even to North Carolina, 

 while in the west it is nearly confined to the northern tier of states, though it reaches 

 along the Rockies to Colorado and along the Sierras to northern California. A second 

 species, intimately related to the other, but with parti-colored instead of clear red hind 

 tibise, Mel. hivitiatus (Say), is a more southern form, but it occurs with the first in many 

 places, and, in Canada, accompanies it from British Columbia to Manitoba, but not 

 eastward. 



It thus appears that ten of the twenty-eight series found in the genus Melanoplua 

 occur in Canada, though but twenty species, or less than one-sixth of the known forms, 

 are included in the list. The list is remarkable for three things : 1, the range of structural 

 diversity as indicated by the number of series represented ; 2, the total absence of all 

 species with excessively abVjreviated tegmina {i.e. only as long or scarcely longer than the 

 pronotum), such as would formerly have been placed unquestioned in Pezotettix, the 

 single one of the known Canadian Melanopli with such tegmina being a true Podisma ; 

 3, that it includes three of the only four well marked cases of wing-dimorphism in the 

 genua Melanoplus. It is true that both the dimorphic forms have not been found in 

 Oanada, but that is in all probaVjility a mere accident, collections from Canada being 

 much rarer. The dimorphism is probably co-extensive or nearly so with the species. 



But it should not be concluded that the above list actually oflfers a fair idea of the 

 true Melanoplan fauna of Canada, Canada is so little explored from a natural history 

 standpoint, especially in its western portions where, in the United States, Melanopli are 

 so very .strikingly diversified, and so many additional forms have been found next the 

 Canadian border, that we must believe that many of them surpass it and are not now 

 known as Canadian, simply from the little attention paid in Canada to this order of 

 insects. We propose, therefore, to conclude this account by a brief review of such 

 Melanopli as may be looked for with some confidence ; we shall discover the probability 

 of a much more varied and numerous series, for the number of genera and species will both 

 be doubled, and the "series" of the genus Melanoplus represented raised from ten to 

 seventeen. All the additional genera, however, belong to the temperate section. 



In the first place we may cite Hesperotettix as a probable inhabitant, since Hesp. 

 pratensis Scudd., is widely diffused along the northern margin of the United States, from 

 Minnesota to Washington, being recorded in my paper from these two States and all the 

 intervening ones. 



Then there is the genus Bradynotes, containing peculiarly broad-chested, robust 

 forms with mere pads for tegmina, all the species of which are confined, so far as known, 

 to the extreme northwest of the United States, — Washington, Oregon, Northern Cali- 

 fornia and Idaho, with Nevada, Montana and Wyoming. No less than four species are 

 found in Washington and two others in Idaho, besides one confined to California, so that 

 it seems altogether probable that one or more of them may be found in British Columbia, 

 if indeed this district do not prove to have its peculiar species. 



The genus Q^daleonotus, founded by me on the species I formerly described as 

 Pezotettix enigma, a clumsy bodied insect with tumid prozona and stout femora, and 

 strikingly dimorphic in its tegmina, ranges on the Pacific coast from Southern Cali- 

 fornia to Northern Washington where it is abundant, and it may almost surely be looked 

 for in British Columbia. 



Another new genus, Asemoplus, created for the reception of Bruner's Bradynotes 

 Montanus, a relatively slender form, likewise with lobiform tegmina, has been found 

 hitherto only in Montana and Washington and not further south, so that it probably 

 ranges northward across the boundary.
