424 FAMILY VI. ACRIDIDJE. THE LOCUSTS. 



and 1,500 feet above tide. Caudell (1900, 511) records the taking 

 of five adults by Prof. Kincaid at Knkak Bay, Alaska, on July 3. 

 "They were taken within a few feet of a small pool in a sphagnum 

 swamp. This pool, only about ten feet in diameter, was surround- 

 ed by vegetation in which the locusts lived. They were captured 

 by causing them to leap into the water where they were easily 

 secured." 



In northern New England borealis is said by Morse to be com- 

 mon in suitable habitats, making its appearance early and reach- 

 ing mnturity in late June or early July, and in the White Moun- 

 tain region is not uncommon in early September. There, as else- 

 where, it is partial to damp surroundings, frequenting the dense 

 grass of moist meadows, bogs, sedgy swamps and mountain tops. 



Scudder (1897, 289) gave the varietal name scandens to the 

 long-winged form of e.rtreinns and states that "it appears to affect 

 high latitudes and altitudes, being found in all the localities in 

 the far north, on the Big Horn Mountains in Wyoming, and on the 

 summits of the mountains in New England, where it is the pre- 

 vailing or exclusive form." E. M. Walker found it common about 

 Ft. William and Nipigon, Ontario, the brachypterous form greatly 

 outnumbering the macropterous. As cxtroniis he also records it 

 (1910, 334) from a number of stations in western Canada between 

 Winnipeg, Man., and Field, B. C. Hebard (1909, 157) mentions 

 extreinus as scarce about Pequaming, Mich., always in damp mea- 

 dows, where the grass was luxuriant and deep. Somes (1914, 86) 

 states that in western Minnesota its numbers are possibly equal 

 to those of M. feiinir-rubrmn, and that it is "found in habitats 

 varying from flat open prairie to dry gravelly hills, and at times 

 even in the tamarack growths of the north. It is one of our ear- 

 liest species and closely follows J/. minor, specimens having been 

 taken June 14, and mating in the field on June 24." 



The Pezotett-lr septentrional it Sauss. (1801, 159), the Calop- 

 temis arctieus F. Walker (1870, G81) and the C. parvus Pro- 

 vancher (1876, 110) are synonyms, while numerous records of Pe- 

 zotetti.i- borealis and ^[el a no/tins boreal is from Minnesota and 

 other points in the northern United States and southern Canada 

 are to be referred to M. faseiatns. 



The Pezotettlr junius Dodge (1876, 9) described from Ne- 

 braska and usually recorded as a short-winged form of M. ex- 

 tremus, differs from typical boreal is in having the apex of sub- 

 genital plate somewhat broader and less produced, the basal por- 

 tion of the furcula more flattened and the pallium not elevated. 

 It is probably to be considered as a western race of borealis.
