86 THE ACRIDIIDAE OF'MINNESOTA 
there conditions of habitat are somewhat similar to those of localities 
where this form has been taken. While 1/7. extremus was not noted as 
abundant during 1911, yet during the summer of 1912 its numbers 
were possibly equal to those of M. femur-rubrum, especially in the 
western part of the State. In our collecting throughout Iowa, we have 
taken this insect only in low areas, with plant forms such as Eleocharis, 
Junci, and Typha, but here in Minnesota we have found it in habitats 
varying from flat open prairie, with Astragali and Koeleria, to dry 
eravelly hills covered with such grasses as Bouteloua and Sporobolus, 
and at times even in the tamarack growths of the north. It is one of 
our earliest species and closely follows M. mimor. At Fergus Falls 
it was taken June 14, and was observed in coitu, in the field, on June 
24. We have taken this species at Redwood Falls, Hanley Falls, Wil- 
kin County, Fergus Falls, Ada, Crookston, Warroad, Lake Winnibi- 
goshish, and Karlstad. 
Melanoplus comptus Scudd. 
Since Melanoplus comptus was named upon material taken, in 
part, from our State, it is included here, although we have no other 
records of its occurrence. It is of small size, and brownish fuscous 
color. Head dull brown, somewhat luteous, more or less smoky and 
very faintly mottled.’ Vertex feebly tumid, only slightly elevated above 
the level of the pronotum; interspace between the eyes as broad as 
first antennal joint; fastigium strongly declivent, rather deeply sul- 
cate throughout; frontal costa equal, as broad as the interspace be- 
tween the eyes, shallowly sulcate at and below the ocellus, biseriately 
punctured; eyes rather large and prominent, much longer than the 
infra-ocular portion of the genae; antennae fulvous, more than three 
fourths as long as the hind femora. Pronotum brownish-fuscous 
above, luteous-testaceous on lateral lobes, the latter marked above on 
the prozona by a dull, broad, piceous stripe, sometimes tinged with 
smoky olivaceous; disk scarcely expanding on the metazona, very 
broadly convex, and passing on to the inferiorly vertical lobes by a 
well-rounded shoulder, nowhere forming distinct lateral carinae; me- 
dian carinae obsolete on the prozona; front margin transverse, almost 
imperceptibly emarginate in the middle, hind margin obtuse-angulate, 
the angle rounded; prozona subquadrate or feebly longitudinal, dis- 
tinctly longer than the closely punctate metazona. The prosternal 
spine short conico-cylindrical, compressed, erect, very blunt; inter- 
space between mesosternal lobes of male at least three times as long 
as broad, the metasternal lobes attingent for some distance. Tegmina 
brownish fuscous, immaculate or very feebly and obscurely maculate 
in the discoidal area, slender, subequal, scarcely expanded on the costa,
