part, upon the gravelly slopes where vegetation is quite sparse. 
During the autumn of 1876, when the true Migratory Locust was pass- 
ing over the eastern part of Nebraska, a large specimen of this long- 
winged 'hopper was seen to alight at West Point, in that State, where 
thewriterwas at the time engaged in hay-making. !t was captured 
and shortly afterwards described as CEdipoda nebrascensis. This is the 
only record of the insect having been taken so far away from its native 
region as since ascertained. Several years later, August, 1881, while 
Spending some time in the vicinity of 
Greeley, Colo., this species was very 
frequently met with both to the north- 
ward and southward of the town, 
upon the bench lands, in company 
with Tropidolophus formosus, a very 
striking species of locust. Again, in 
1889, while collecting specimens of

various kinds in tin 1 extreme western 
part of Nebraska, a few individual 
specimens of this insect were taken; while, a year or two previously, it 
was obtained from Prof. F. W. Cragin. of the Washburn College, lo- 
cated at Topeka, Kans., who collected it in Barbour county, in that 
State. 
This insect is well represented in the accompanying illustrations, 
which show it with and without spread wings, Fig. 19, being that 
with them spread, and Fig. 20 that in which it is shown with them 
closed. The following description will render its determination quite 
easy: 
Tegmina and wings longer than the body; the former spotted with brown, the 
latter blue at base, but gradually becoming black toward the disk. 
Vertex between the eyes broad; middle foveola circular, open in front with a 
slight median carina; frontal costa rather narrow, somewhat expanded at the ocel- 
lus. Bulcate, expanding at lower extremity. Lateral facial costa nearly parallel 
with frontal. Median carina of the pronotum crested, as in Dt8808teira Carolina, 
only much higher; cut in front of the middle by last transverse incision of prono- 
tum. Posterior part highly arcuate, anterior part nearly straight. Lateral carina 1 
slight, approaching a little in front of middle, where they are cut by two transverse 
incisions; then running parallel to median carina to base of occiput. Posterior 
margin of pronotum a little less than a right angle; the front margin advancing 
slightly upon the occiput. Tegmina moderately wide, slightly arcuate in front, 
nearly straight behind ; about one-third longer than the abdomen. Wings about 
one eighth of an inch less, <|uite broad. Posterior femora not or but slightly chan- 
nelled below, not quite reaching the tip of the abdomen in the female, or very 
slightly surpassing it in the male. Antenna- aboul as long as the head and prono- 
tum combined. 
Color brow nisli testaceous. 1 lead and pronotum cinereous, w ii h a greenish tinge. 
Clypeus lurid. Tegmina dirty yellow, spotted with brown, the spots on outer half 
running together so as to form irregular narrow bands; median vein brown half its 
length, bordered by yellow: spots on inner portion large. Wings bluish at base for 
about one-fifth their length, outer third yellow , sprinkled with brown spots at apex.
