Scudder. ] 64 [November 6, 
and entire, supraanal plate rounded, triangular, of about equal 
length and breadth, the marginal apophyses of the preceding seg- 
ment reduced to a pair of slight blunt tubercles; anal cerci small, 
compressed, the basal two-thirds straight, slightly tumid, directed 
backward, tapering slightly, the apical third forked, the forks at 
right angles, the upper twice as broad and half as long again as the 
lower, compressed, straight, but a little incurved, rounded at the tip; 
the lower more nearly in the course of the basal portion, straight, 
bluntly tipped; basal tooth of the lower valves of the ovipositor of 
the ? sharp, triangular, as long as broad. 
The general color above is a very dark, almost blackish brown, the 
3 darker than the ?, beneath dirty olive. The face is more or less 
purplish, the sides of the head flecked with yellowish green and with 
black; antennz reddish at the base, becoming more and more fuscous 
apically; behind the eyes is a black band which crosses the upper 
margin of the lateral lobes of the prothorax, but from the general 
infuscation of the latter is not very distinct; the single female has a 
broad median belt of rust red on summit of head and prothorax, 
fading or becoming infuscated posteriorly. Tegmina very dark 
brown or blackish, especially in the ¢, with a few inconspicuous 
black flecks down the median area. Fore and middle femora reddish 
brown, infuscated above, especially at the apex; hind femora mostly 
blackish externally, with an oblique, more or less broken, median 
and basal band of dull testaceous in the males; knees black; hind 
tibie red, with a black or blackish, narrow basal annulus in the 
males, the spines black ; the tarsal joints red, black tipped. 
Length of body, ¢, 22 mm., ?, 26 mm.; of antenna, J, 10.5 mm., 
@, 9.5 mm.; of tegmina, o, 16.5 mm., ?, 20.6 mm.; of hind femora, 
3,13mm.,?,14mm. 24,1 %. North Carolina, Morrison. 
The species has the general aspect of M. femur-rubrum (Burm.), 
but from its forked cerci is more nearly allied to M. collinus gels 
and to the species next described. 
72. Melanoplus arizonee. Of medium size. Head rather 
small, subcompressed, not elevated, moderately arched; eyes moder- 
ately prominent; vertex between the eyes as broad as the length of 
the basal antennal joint, the foveola very shallow, with moderately. 
sharp, but not prominent, lateral walls, which give it a® subspatulate 
form; frontal ridge rather broad, above slightly tumid, with punctu- 
late sides, scarcely broader below, sulcate at the ocellus, and to some 
degree below it. Pronotum rather slender, rather uniform, but
