General form of head and body very similar to Melanoplus; an- 
tennae usually rather short; pronotum variable but always short and 
usually subcylindrical, though sometimes, especially in the females, 
expanded posteriorly, never contracted at the middle, generally with 
very feeble transverse sulci; front margin truncate, hind margin trun- 
cate, subtruncate, or even emarginate; prozona generally considerably 
longer than, sometimes twice as long as, the metazona, very faintly 
punctate; metazona generally densely punctate; median carina gen- 
erally present though slight on the metazona and often more feeble 
or obsolete on the prozona. Prosternal spine always distinct, usually 
prominent, generally conical and blunt. Mesosternal interlobes of 
the male distinctly transverse, usually even more strongly so in the 
females; metasternal interlobes of male usually distant, rarely approxi- 
mate, never attingent; in the female they are usually even more widely 
separated. Tegmina wanting, in our species, or short and lateral. 
Hind femora rather long and slender; spines of hind tibiae 9 to 11 
(rarely 8) in outer series. Abdomen more or less distinctly com- 
pressed, in the male more or less clavate and recurved; cerci variable, 
often styliform; furcula feebly developed, if present at all; ovipositor 
of female variable, typically it is exserted, sometimes exceptionally 
extended, or sometimes partially withdrawn in the then obtusely ter- 
minating abdomen; cerci of female rather strongly developed and 
styliform. 
The limitations between this genus and some of the genus 
Melanoplus are not great and while in typical forms the distinction 
can be readily made, yet in some forms they approach very closely. 
The genus is more widely, though sparsely, distributed than any other 
genus of the Melanofpli, and is of a distinctly boreal type encircling 
the globe in its range. In America they have heretofore been known 
only from two widely separated regions, the Rocky Mountains in the 
West and from Ontario to New York and Maine in the East. We 
have recently found one species in St. Louis County, in the northeast- 
ern part of this State.
