96 THE ACRIDIIDAE OF MINNESOTA 
form, to which the varietal name P. n. volucris has been applied, may 
yet be found within our borders since it occurs in Nebraska. The 
species may readily be recognized by the generic characters and by 
reference to Plate I, 9. It is an active insect and has been found 
under widely varying ecological conditions. The following notes, 
made in Iowa, are of interest in this connection. “It appears at first 
glance very much like some of the brachypterous forms of Melanoplus, 
but the compressed body and prominent head serve to separate it 
even in the field. We first took it at Fort Dodge in sweeping tall 
grasses, in an upland meadow; a more careful examination of the 
vegetation resulted in the discovery of numerous specimens, crouching 
among the stems and dead leaves at the bases of the plants. At 
Eddyville and Bayfield it was found among Carices and Junci along 
streams, while at Onawa it was taken among the Saggitariae in the 
margin of a pond.’ Exactly similar conditions and variations have 
been noted in Minnesota, and we have taken it here in low marshes, 
along lakes, and at the tops of high gravelly hills sparsely covered 
with grasses and weeds. We have taken this species at Pipestone, 
Mankato, Fergus Falls, Detroit, Wadena, and Mahtomedi.
