Scudder.} 70 [November 6, 
apophyses of the preceding segment consist of wavy, depressed, 
conical, pointed projections diverging at nearly right angles, about 
half as long as the cerci. Anal cerci forming very simple com- 
pressed laminz, the basal three-fifths straight, tapering a little and 
directed backward and a little upward, the apical two-fifths also 
straight, enlarging slightly, keeping the same direction but bent a 
little inward, the outer surface a little concave, the extremity 
squarely docked, its corners rounded; basal tooth of the lower valves 
of the ovipositor of the ° sharp, triangular, but much broader than 
long. 
The general color is a dirty cinereous above, a dingy clay yellow 
below; antennez dull testaceous, becoming somewhat ferruginous 
toward the tip; a pretty broad and usually distinct blackish brown 
or piceous band extends from behind the eye along the upper border 
of the deflected lobes as far as the posterior sulcus, and sometimes as 
a blurred and expanded continuation of it, across the posterior lobe 
also. Tegmina brownish cinereous, the anal field sometimes a little 
lighter, the median field enlivened to a greater or less extent, but 
seldom conspicuously, by an alternation of blackish and pallid longi- 
tudinal quadrate spots. Hind femora dirty clay brown with dusky 
incisures, above with a median and subapical dusky or dark fuscous 
patch; hind tibize red, with black tipped spines. 
Length of body, ¢, 24 mm., 2, 30 mm.; of antenne, do, 13.5 mm., 
?, 12 mm.; of tegmina, J, 21 mm., 2, 24 mm.; of hind femora, 3,14 
mm. ?, 165 mm. 12¢,11 2. Pueblo, Colorado, Aug. 30-31. 
Taken in abundance in the river bottom, by Mr. Bowditch and 
myself. 
This insect is closely related to M. Packardu Scudd., but by its 
dingy coloring presents a very different appearance. 
77. Melanoplus curtus. Of rather small size. Head of 
moderate size, not elevated, moderately arched. Eyes rather small, 
somewhat prominent in the ¢. Vertex between the eyes as broad 
(3), or nearly half as broad again (2), as the first antennal joint; 
foveola shallow, with distinct and abrupt, but rounded bounding 
walls, which diverge a very little in front of the eyes and then con- 
verge; frontal carina scarcely contracted above, where its face is 
either flat (4) or slightly tumid (?), at and below the ocellus rather 
narrowly sulcate, deeper in the ¢ than in the ?; antennz longer 
than usual. Pronotum simple, the posterior lobe scarcely expand- 
ing, minutely rugulose; median carina distinct only on the posterior 
lobe and at the anterior extremity of the anterior lobe; elsewhere
