SUBFAMILY ACRIDINAE 87 
surpassing a little the hind femora; wings rather narrow, pellucid, 
glistening, the veins pale blue on the lower, fuscous or blackish on the 
upper half. Fore and middle femora but little tumid, luteo-testaceous, 
blotched with fuscous; hind femora luteo-ferruginous, obscured with 
fuscous above, and on the outer face above, interruptedly, so as to 
cause feeble signs of dusky fasciation, beneath chrome yellow, the 
genicular arc dull luteous, edged only with fuscous; hind tibiae red, 
narrowly pallid at extreme base, the spines black. on apical half, ten 
to eleven in number in the outer series. Extremity of male abdomen 
a little clavate, somewhat upturned, the supra-anal plate long and 
triangular, the basal three-fifths with well-rounded, uptilted sides, be- 
yond which the plate is laterally notched and contracted, the apex 
produced and very acute-angulate, the tip blunt, the median sulcus 
broad and not very deep, terminating with the basal portion; furcula 
consisting of a pair of depressed, uniformly tapering, acuminate, 
slightly divergent fingers less than a third as long as the supra-anal 
plate; cerci rather short and not very broad, regularly spatulate by 
the regular, slight, and gradual mesial contraction, the apical half 
‘rather strongly incurved, externally hollowed, the apex well rounded, 
not nearly reaching the tip of the supra-anal plate; infracercal plates 
well developed, laterally twice as broad as the cerci, well rounded, dis- 
tinctly shorter than the supra-anal plate ; subgenital plate scoop-shaped, 
but slightly angulate behind laterally, the apical margin scarcely ele- 
vated and most feebly notched. Length of body, male, 19 mm., teg- 
mina 15.75 mm., antennae 9 mm., hind femora 11.25 mm. Described 
(Scudder, Revision of American Melanopli, Proc. U. S. Natl. Museum, 
Vol. XX, p. 302) from two males, one of which came from northern 
Minnesota and the other from Sydney, Nebraska. The species goes 
in the group with the following and doubtless will be found as rare 
and local. 
Melanoplus angustipennis Dodge 
Melanoplus angustipennis is an insect of medium size and rather 
dark coloration; the pronotum is dark fuscous but lighter on the lat- 
eral lobes with a subluteous median streak, bordering a broad piceous 
postocular band on the prozona; metazona with the hind margin dis- 
tinctly obtuse-angulate. The hind tibiae vary from glaucous to bluish, 
apically feebly lutescent. Extremity of male abdomen somewhat 
clavate but scarcely recurved; cerci short and distinctly spatulate at 
tip; furcula consisting of a pair of slender, cylindric, rather strongly 
divergent, arcuate, regularly tapering, acuminate fingers not a third 
as long as the supra-anal plate. This insect is apparently almost en- 
tirely confined to areas of sandy soil and has, in most cases, been taken
