b 2 . Pronotum diversified in color only by longitudinal stripes, 
the dorsum distinctly tectiform; tegmina without pale stripes 
(though they are occasionally indicated). 
c 1 . Tegmina lobiform, little or no longer than the pronotum, 
their upper edges not attingent. 
d l . General color dark brown,occasionally with a tinge of 
green; tegmina short ovate, distinctly shorter than the 
pronotum. pacificus Scudd. 
d 2 . General color grass-green; tegmina long oval, scarce¬ 
ly shorter than the pronotum. 
e 1 . Slender. Pronotum decidedly angulate behind, 
very preceptibly widening posteriorly. 
coloradensis n. sp. 
e 2 . More robust. Pronotum with hind margin broad¬ 
ly rounded, of nearly equal width throughout. 
curtipennis Scudd. 
c 2 . Tegmina fully developed or abbreviate, when the latter 
nearly or fully twice as long as pronotum, their upper edges 
overlapping. 
d l . Tegmina and wings abbreviate, much shorter than 
the body.. brevipennis Thom. 
d 2 . Tegmina and wings distinctly surpassing the abdo¬ 
men, or sometimes in the female only equalling it. 
pratensis Scudd. 
A 2 . Pronotum decidedly tectiform; both prozona and metazona, both 
on dorsum and lateral lobes, equally and distinctly rugulose. 
b 1 . Tegmina elongate, two to five times as long as broad, round¬ 
ly acuminate at tip..... speciosus Scudd. 
b 2 . Tegmina ovate, at most one and one-half times as long as 
wide. floridensis Morse. 
Melanoplus sanguinsus new species. 
Rather above the medium in size, a moderately robust insect hav¬ 
ing the general color aspect of M. atlanis and its allies, but differingfrom 
these species by its more robust hind femora which are rich blood-red 
inside and below, and in having the hind tibiae very decidedly bluish- 
green as in M. occidentalis and some other species like M. glaucipes 
Scudder and M. regalis Dodge. 
Head a little wider than the front edge of pronotum; occiput some¬ 
what elevated above the plane of its disk, eyes fairly large but not very 
prominent even in the males; vertex a very little wider (tf), or about 
twice as wide ( 9) as diameter of basal antennal joint; the fastigium 
roundly depressed and rather broadly and deeply sulcate; frontal costa 
about as wide above as vertex, broadening a trifle below and reaching 
the clypeus, punctuate above, gently sulcate at ocellus and below; an¬ 
tennae a trifle longer than head and pronotum together. Pronotum with 
the sides of anterior lobes about parallel, hind lobe considerably expand¬ 
ing towards the rear, transverse sulci profound, the last about the mid¬ 
dle; median carina faint on anterior lobes but prominent on posterior, 
the latter wiih its hind edge angulate. Anterior portion of male meso- 
sternum provided with a large blunt protuberance. Tegmina rather nar¬ 
row, tapering but little apically, reaching beyond the tips of hind femora 
in both sexes. Anterior and middle femora not greatly enlarged in 
male, the hind pair moderately robust, a little surpassing the abdomen 
in both sexes. Extremity of male abdomen neither clavate nor recurved, 
the subgenital plate short, the apex but little produced and not notched. 
Supraanal plate broadly triangular, the sides rounded and the apex a 
little produced, the middle furnished with a rather deep narrow groove 
which runs from the base nearly to the apex, a little wider and shallower 
near its termination, the sides undulate near base and projecting over 
the cerci. The latter nearly equal throughout, a little more than twice 
as long as greatest width, the apical half bent inwards and with their 
outer face slightly indented, the lower corner of apex obliquely docked.
