REPORT OF ENTOMOLOGIST. 
67 
, Entire insect sparsely clothed with rather long erect light-colored 
hairs. Head a little wider than front edge of pronotum, the eyes only 
moderately prominent, a trifle longer than the cheeks below them; ver¬ 
tex rather broad, nearly twice the diameter of basal joint of antennae, 
the fastigium shallowly but broadly sulcate, depressed and roundly unit¬ 
ing with upper extremity of the broad prominent frontal costa, the latter 
with straight edges and expanding but little below where it reaches the 
clypeus, broadly sulcate at ocellus and below and with a few scattered 
punctures above. Antennae a little longer than combined length of head 
and pronotum. Pronotum with the anterior lobes a very little longer 
than the hind lobe, smooth and shining, the sides parallel; hind lobe di¬ 
verging posteriorly, the surface profusely punctate, the hind margins 
of disk broadly angulate; median carina quite conspicuous on posterior 
lobe, almost obliterated on anterior lobes; transverse sulcus rather 
prominent, especially the posterior one which is profound and nearly 
straight. Prosternal spine rather long, fairly stout, regularly pyrami¬ 
dal, straight and with the apex rounded. Space between mesosternal 
lobes about half again as long as broad, divergent behind. Anterior and 
middle femora not especially heavy; the hind pair somewhat robust. 
Apical portion of abdomen very little or not at all enlarged; subgenital 
plate longer than wide,directed backward and gently upward,the extreme 
apex a little produced,entire but with the surface just before it depressed 
so as to give it the appearance of being notched as in atlanis and allies; 
supraanal plate broadly triangular, the sides sinuate and with the edges 
on basal half raised, the middle provided with two 'rather prominent 
nearly parallel carinae inclosing a profound longitudinal channel which 
reaches from the base nearly to the apex, but which is interrupted a 
little beyond the middle by a low cross ridge joining the bounding walls. 
Marginal apophyses a little longer than width of preceeding segment, 
evenly tapering to a point, their bases touching, directed backwards and 
outwards so that their tips cross beyond the outer edge of the walls of 
central fovea of plate. Cerci about twice as long as broad, of nearly 
equal width, their lower outer edge gently truncate and the apex rounded, 
directed backward and inward. 
Length of body, <3% 18 mm.; of pronotum, 3.4 mm.; of antennas, 
7 mm.; of tegmina, 8 mm.; of hind femora, 10.25 mm. 
Habitat. Fort Collins, Colorado, a single $ on August 16th. 
By the use of Scudder’s table for separating the species of 
Melanoplus as published in his “Revision of the Melanopli” this 
insect seems to come near M. dowsoni. In the characters of 
the tip of male abdomen it reminds one a little of M. intermedins, 
but other characteristics throw it out of the atlanis group.
