Genus Podisma Lutreille. 
Scudder says: “This genus is more widely extended than any other of 
the Melanopli [Acridiinae], being the only one not confined to America. 
It is a distinctly boreal type and encircles the globe. The species are 
confined to high altitudes as well as high latitudes, a number being- 
alpine or sub-alpine in their respective localities.” They are found in 
Siberia and Japan, as well as in the mountains of southern and eastern 
Europe. 
In Podisma, the tegmina are never well developed, and are often en- 
tirely wanting. The pronotum has not very distinct sulci or carinae; 
it is either the same width throughout or larger posteriorly, never con- 
stricted in the middle. 
9. Podisma variegata Scudder.- — The vertex sloping downward, nar- 
rower than the eye; median carina not distinct. Frontal costa narrower 
than space between eyes, sulcate; foveolae not distinctly marked off, 
trapezoid. Antennae filiform, as long as or longer than hind femora. 
Pronotum sub-cylindrical, flaring gradually towards back; both anterior 
and posterior margins truncate; median carina low but distinct; lateral 
carinae wanting ; prozona nearly twice the length of the metazona. Teg- 
mina and wings wanting. Hind femora slender, reaching to tip of ab- 
domen, but not to tip of ovipositor in the female. Sub-genital plate in 
male with a distinct sub-apical tubercle; furcula no longer than wide; 
cerc-i projecting dorsally, considerably above the supra-anal plate; nar- 
rowing sharply to middle, then slightly enlarging, the tip about half the 
width of the base, somewhat flattened. 
Color : — General color olive green ; face puncate with yellow ; disk of 
pronotum green; a chocolate streak from the eye along the head, pro- 
notum, meso- and meta-notum, below this, bright pinkish yellow. In the 
male there is. a distinct red-yellow streak along the mid-dorsal line of 
the thorax and abdomen. The abdomen is green tinged with dark red, 
somewhat yellowish underneath. The hind femora are green, with three 
yellowish cross bars; the knees fuscous; the tibiae green, becoming red- 
dish at the apical end. 
Measurements: — Length of body, male, 19 mm., female, 22 mm.; pro- 
notum, male, 3.5 mm. ; hind femora, male, 10 mm., female, 12 mm. ; an- 
tennae, 12 mm. 
Genus Melanoplus Stal. 
To this genus belong 136 or more species, a greater number than is 
in any other genus of Saltatoria. They are also the most commonly 
found group in the northern United States. The infamous Kockv Moun- 
tain Locust is in this genus. 
“Body moderately stout; generally feebly compressed. Head not 
prominent, but little if any longer than prozona. Face almost vertical. 
Disk of pronotum usually only half as long again as the average 
breadth; the prozona distinctly longer than the metazona, its edges 
parallel, its surface a little convex and faintly punctate; metazona with 
its edges more or less diverging backward, its surface flat and densely 
punctate; lateral lobes of pronotum vertical or nearly so, and usually 
marked on their upper half with a black band. * * * Cerci of male 
exceedingly variable in form. * * * Furcula usually developed and
