Furcula consisting of a pair of moderately depressed, slender, parallel 
fingers equal and attingent on basal half, tapering for a short distance 
and slender and equal in outer third, slightly less than half as long as 
the supraanal plate. 
General color varying from a pale testaceous to a dull wood brown, 
in the lighter individuals tinged above with ferruginous. Sides of head 
back of the eyes, and pronotum to last transverse incision provided with 
a well defined piceous band, in some specimens a trifle interrupted by 
light patches. Occiput usually provided with a similar dark band that 
begins at the vertex and extends backward to front edge of pronotum. 
Disk of latter usually pale, but sometimes becoming a little infuscated 
in middle. Tegmina provided with a discal row of fuscous dots in a pale 
field, beyond the basal half these also occupy the remainder of the wing. 
Hind femora provided above and on upper half of outer face with three 
dusky bands, the apex black preceded by a pale annulus, inner face and 
lower outer edge, together with lower sulcus, bright blood red; hind tib¬ 
iae bluish-green, the knees and genicular lobes of femora bluish-white. 
Length of body, <6\ 22.5 mm., 9> 25 mm.; of antennae, 9.5 mm., 
9 10 mm.; of pronotum, J4 5.1 mm., 9» 5.5 mm.; tegmina, 20 mm., 
9, 21 mm.; of hind femora <6\ 13 mm., 9? 14 mm. 
Habitat, 3s and 9s Lamar and Las Animas, Colorado. 
This insect would fall in Scndder’s table for the separation of 
our species of Melanoplus near bruneri , excelsus and utahensis. 
The table would have to be modified for its reception as follows. 
(Bottom page 131): 
g 2 . Apical margin of subgenital plate of male conspicuously eleva¬ 
ted above the lateral margins and sometimes greatly prolonged 
posteriorly; mesosternum of male in front of lobes with a central 
swelling, forming a blunt tubercle (5. Utahensis series). 
h l . Apical margin of subgenital plate of male entire; lobes of 
furcula not exceptionally broad. 
1 1 . Subgenital plate only moderately prolonged. 
sanguineus n. sp. 
1 2 . Subgenital plate greatly but not excessively prolonged. 
j 1 . Interval between mesosternal lobes of male more than 
twice as long as broad, of female a little longer than 
broad; male cerci more than twice as long as broad; 
apical margin of subgenital plate of male, as seen from 
behind, subtruncate. bruneri Scudd. 
j 2 . Interval between mesosternal lobes of male much less 
than twice as long as broad; of female transverse; male 
cerci less than twice as long as broad; apical margin of 
subgenital plate of male, as seen from behind, rounded. 
excelsus Scudd. 
h 2 . Apical margin of subgenital plate of male deeply notched on 
either side of middle; lobes of furcula exceptionally broad, sub¬ 
equal throughout; subgenital plate excessively prolonged. 
utahensis Scudd. 
Melanoplus tristis new species. 
A rather small, slender, short-winged insect that bears a strong 
resemblance to M. artemisiae but which more properly belongs to the 
Aridus series since it has the cerci and furcula of the male as found in 
the last named species. Entire insect quite strongly hirsute or pilose. 
General color dark reddish brown,, varied with darker brown and 
piceous. Head about as wide ( 9) or a little wider (tf 1 ) than the front 
edge of the pronotum, the occiput a little raised above the plane of the 
latter; eyes large and quite prominent, sub-globular in the male, consid¬ 
erably less prominent and with the anterior edge decidedly straight in
