Seven males, G females. Coast of Labrador, beyond the timber line, 

 at latitude 59 north, Jewell D. Sornberger (specimens collected in 

 spirits). 



Fieber also reports it from Greenland and North Cape, Norway. It is, 

 however, not included in the European fauna either by H. Fischer or by 

 B runner von Wattenwyl; yet Fieber credits specimens to the Vienna 

 Museum, in which city Brunner lives. Hofrath Bruuner writes me that 

 he possesses specimens from Labrador, Hudson Bay, and Valdivia, 

 Chile. I can not forbear expressing a doubt about the accuracy of this 

 last locality. 



As Melanoplus and Podisma are the genera of Melanopli most abun- 

 dant in forms and most widely spread, the former being especially true 

 of Melanoplus, and as the present form is the species of Melanoplus 

 most nearly allied to Podisma, and, like most of the species of the 

 latter genus, is peculiar to high latitudes or altitudes, it seems proper 

 to regard M. borealis as an archaic form, perhaps more nearly than any 

 other resembling the original form from which the Melanopli as a whole 

 have descended. 



Mr. Samuel Henshaw recently compared for me a female specimen of 

 this species from Labrador with Walker's type of Caloptenus arcticus 

 in the British Museum. He found them to agree except in length of 

 wings, which in Walker's specimen, a unique, "extend slightly beyond 

 the abdomen ;" the prosterual spine was the same. I have accordingly 

 introduced it in the synonymy with a question mark; if it belongs here 

 the range of the species should be extended to whatever point it may 

 have been in "Arctic America" that Doctor Kae collected his specimen. 



The specimens which I have seen were taken by Mr. Sornberger 

 August 15-1G at the Esquimaux village of Kama. He tells me that 

 they were all taken on the banks of a mountain brook fed by the melt- 

 ing snows of the summit near by. They were most abundant where 

 the vegetation was most luxuriant at the boulers of the brook; none 

 were found below an elevation of 200 feet nor above 1,500 feet, at which 

 altitude herbaceous plants became few and scattering. Mr. Sornber- 

 ger can not say upon what it fed, but it was not found on any of 

 the shrubby plants common there Betula, Vaccinium, Ledum, Salix, 

 Eiupetriim, etc., though he thinks he saw it on some of the Cyperaceae. 



18. ALLEXI SEKIES. 



In this small series the prozona of the male is slightly longitudinal, 

 and the interspace between the mesosternal lobes in the same sex only 

 a little longer than broad. The antennae are very long. The tegmina 

 are always abbreviate, but vary considerably, being either elliptical, 

 attingent, and about as long as the pronotum, or lanceolate, overlap 

 ping and reaching a little beyond the middle of the hind femora. The
