SUBFAMILY ACRIDINAE 79 
acquire habits differing from the normal habits of the group. This 
species is in many ways the most adapted to woodland conditions of 
any of our Acridinae, except possibly Chloealtis conspersa. It is com- 
monly found in woodlands of high and dry soil, where it is usually 
associated with Spharagemon bolli. As Lugger has stated, it is espe- 
cially fond of the wild grape, Vitis, of various species, upon which it 
commonly feeds. We have taken it, fully matured, at White Bear 
Lake as early as June 12. 
Although doubtless common throughout the southern part of the 
State, we have records only of the following places for this species: 
Albert Lea, Worthington, Redwood Falls, St. Anthony Park, White 
Bear Lake, Gray Cloud Island, Hinckley, Detroit, Bemidji, Duluth, 
and Tower. We have not as yet taken it in the Red River Valley, 
although in some places the conditions appear right for this species 
and the forms commonly associated with it are to be found. 
Melanoplus gracilis Brun. 
Melanoplus gracilis is a rather small insect of greenish colora- 
tion, though sometimes brownish above; the hind legs bright green; 
postocular band broad, extending back across the lobes of the pronotum 
and percurrent, though sometimes slightly enfeebled on the metazona, 
bordered below by a light band. This is a sylvan species and appar- 
ently prefers such tangles of shrubby plants as a thicket of elder 
(Sambucus) undergrown with blackberry. From one such spot we 
took twelve of these pretty little insects within less than half an hour. 
The species matures about the middle of July or slightly earlier and 
continues until cold weather. We have often found it associated with 
the preceding species and with Spharagemon bolli but more commonly 
in the lower parts of woodlands, as along the margins of streams. We 
have taken this insect only at Red Wing, Mahtomedi, and Redwood 
Falls, but this scanty record does not, in all probability, represent, its 
range within the State and it is probable that it will be found at many 
other points in the south and central parts of the State. 
Melanoplus occidentalis Thom. 
‘Melanoplus occidentalis is rather small, reddish brown, lighter 
below and at least dorsally rather strongly mottled with dark spots; 
postocular band rather brownish in color, continuous along the sides 
of the head but much fainter or absent on the lateral lobes of the 
pronotum, although there is frequently a more or less broken blackish 
patch on the upper portion of at least the prozona. The tegmina are 
brown with a slender, median, yellow stripe, and frequently maculate
