4 J Canadian Arctic Expedition, 1913-18 
Labrador, Hudson Bay and Alaska. The specimens described by Scudder in 
his "Revision of the Melanopli" came from the Esquimaux village of Ramah, on 
the coast of Labrador, lat. 57° N., while the Alaska specimens recorded by 
Caudell (Pap. Harriman Alaska Exp., Proc. Wash. Acad. Sc, vol. II, pp. 511- 
512, 1900) were taken at Kukak Bay, Alaska Peninsula. 
I have a large series of this species from Nain (lat. 56° 30") and Hopedale 
(lat. 55° 24"), Coast of Labrador, an examination of which convinced me 
that they are not specifically distinct from M. extremus Walk., a species also 
recorded from Labrador and Arctic America, which was placed by Scudder in a 
different section of the genus. On submitting this question to Mr. Hebard, I 
learned that he had already placed M. extremus as a race of horealis in his unpub- 
lished notes on this group, and Messrs. Morse and Blatchley are also of the 
opinion that the two forms are conspecific. This being the case, M. horealis, 
as a species, is by no means exclusively arctic, but ranges over nearly the whole 
of Canada and extends also into various parts of the northern United States. 
It is, however, a typically boreal form and probably reaches its highest develop- 
ment in the Hudsonian zone. 
Melanoplus fasciatus is a species of similar range and has also been recorded 
from Nain, Labrador, so that it may be fairly included in the arctic fauna. 
Several other species of Acrididae have been reported from "Arctic America" 
chiefly by F. Walker (Cat. Derm. Salt. Brit. Mus., III-IV, 1869-71), but in the 
absence of definite localities it is uncertain whether they were taken in the 
Arctic zone proper or the Hudsonian. These are Acrydium granulaium Kirby, 
Chorthippus curtipennis (Harr.), Hippiscus apiculatus (Harr.) and Melanoplus 
femur-ruhrum (DeGeer). The type locality of A. grariulatum is in lat. 65°, and 
it was taken by Adam White (Richardson, Arctic Search. Exp., II, p. 360, 1851) 
at Fort Simpson (lat. 61° 30') and at the junction of the Mackenzie and Slave 
rivers, so that it cannot be certainly regarded as arctic on the basis of these 
records. The other records are indefinite and that of M. femur-rubrum. almost 
certainl}^ erroneous, the species referred to being probably M. horealis. 
A few other Orthoptera may be mentioned as very possibly ranging into 
the arctic regions. Melanoplus kennicotiii Scudd. and M. atlanis (Riley) 
were taken by Kennicott on the Yukon river, Alaska. The former has also 
been recorded from Saskatchewan, Alberta and Montana, while the latter is 
widely distributed over the greater part of North America, extending into 
Mexico. 
Melanoplus hruneri Scudd. {M. alaskanus Scudd.) is also recorded from 
Alaska and is widely distributed in Canada in the Boreal region. 
Acr?/dnwi 6nmneriBoliver (which is perhaps the true A. granulatum {K.\rhy) , 
and Melanoplus bivittatus Say are recorded from the Hudson bay region, while 
Circotettix verruculatus (Kirby) ranges far north, the type specimen having come 
from lat. 57° N. 
All the species mentioned al)ove are locusts or "short-horned grasshoppers" 
(Acrididae), but there is one species of "long-horned grasshopper" (Tettigoni- 
idae), which has some claim to membership in the Arctic Fauna. This is Idiono- 
tus sphagnorum (Walk.) (syn. 7. hrevipes^ Caud., Platycleis fletchcri Caud.), 
which was originally described from St. Martin's Falls, Hudson Bay. It was 
redescribed by Caudell (Proc. U.S. Nat. Mus., XXXII, p. 396, 1907) as Idionoius 
brevipes from a single male, taken by Kennicott in "Arctic America" (Caudell, 
I.e.). This same specimen had already been mentioned but not described by 
Scudder (Can. Ent., XXVI, p. 182, 1894) in his characterization of the genus 
Idionotus, and is stated to have been "collected by Kennicott somewhere on his 
explorations in or going to Alaska." This species is now known also from 
northwestern Ontario, Manitoba and Alberta. 
'I am indebted to Mr. W. S. Blatchley for the synonymy of Idionotus'brevipes Caud. with'^ Decticus 
sphagnorum Walk. I had long suspected this to be the case, as we have only one northern Decticine, aa 
far as known.
