SUBFAMILY ACRIDINAE 73 
olivaceous tinge, variegated with dark fuscous or brown, pilose; the 
females more distinctly olive or in life a lighter tone of green. Post- 
ocular band strong and broad, extending the whole length of the 
lateral lobes of the pronotum; median carina slight but distinct in both 
sexes. Pronotum distinctly compressed in male and cylindric-sub- 
sellate in the female. Tegmina are entirely wanting in both sexes. 
Hind femora flavo-testaceous, distinctly trifasciate; hind tibiae green- 
ish. Abdomen distinctly compressed in both sexes and with a distinct 
dorsal carina, in the male clavate and somewhat recurved; sub- 
genital small with apex tumid; supra-anal triangular with a subrectan- 
eular apex ; furcula consisting of a pair of approximate, short, tapering, 
black spines, hardly longer than the last dorsal segment; cerci cas- 
taneous, black-tipped, suberect, long, slender, tapering in the basal 
half and subequal beyond, the apical portion less than’ half as wide as 
the extreme base. Our specimens include immature males and one 
mature female. The measurements of the female are: length 23.5 mm., 
hind femora 11.25 mm., antennae 10.5 mm. As stated above we have 
taken this only in St. Louis County, where we found it on such shrubs 
as Cornus and Rubus, July 29, 1912. 
MELANOPLUS Stal. 
Melanoplus includes insects of medium or large size, some species, 
however, quite small, moderately stout, generally somewhat com- 
pressed, more or less, but generally feebly pilose. Head moderately 
or not at all prominent, generally little if any longer than the prozona, 
unless the latter, as rarely, is transverse; face almost vertical or in 
some cases slightly oblique. The vertex is gently tumid; eyes rounded 
and oval but not markedly elongate; fastigium more or less declivent, 
passing almost insensibly into the frontal costa, always more or less 
sulcate, with elevated lateral margins, generally more strongly so in 
the male than in the female; the antennae slender or moderately stout, 
variable in length but never very short, never longer than the hind 
femora, and rarely, if ever, more than twice as long as the pronotum. 
Pronotum generally compressed to a greater or less degree, length 
rarely or never twice as great as average breadth; metazona generally 
more or less flaring, its disk plane and densely punctured, while that 
of the prozona is generally slightly convex and rarely flaring anteriorly, 
or if so but slightly, at most slightly punctate, and generally longer 
than the metazona; hind margin of pronotum obtuse-angulate or some- 
times truncate; median carina generally faint or obsolescent on pro- 
zona and always distinct on metazona; lateral carinae are normally 
obsolete although often indicated by a distinct, though rounded, shoul-
