collected into a mesial series ; hind femora very obliquely and broadly bifasciate with 
blackish brown, the tip black, the superior carina yellowish ; hind tarsi dull, almost 
dusky, yellow. Cerci of male rather small, compressed, simple, but little tapering,

One male and two finilies were taken at the Souris River. 
9. Gomphocerus clepsydra nov. sp.—Brownish yellow ; antenne infuscated at the 
slightly expanded tip; head more or less spotted and banded with dark brown. and 
blackish, but with a lighter yellow, immaculate, vertical stripe between the lateral 
carine of the face, and the deep sulcation following the lower angle of the eyes; this 
sulcation is black, shading off into brown posteriorly ; a broad dark band, blackish 
above and edged at this point with yellow, extends from behind the eye upon the 
pronotum ; it is of equal width as far as the greatest constriction of the lateral caring 
of the pr onotum, but beyond this narrows rapidly, and scarcely reaches the posterior 
edge of the same : a small triangular patch of the same colour appears, however, at 
the posterior lateral angles of the pronotal disc; and the lateral lobes of the pronotum 
are heavily marked with the same, especially i in front, the lower portion always imma- 
culate ; tegmina half the length of the abdomen, brownish, with a few longitudinal 
fuscous flecks in the lower half; hind femora blackish along the middle, deepest next 
the carine ; hind tibia yellowish, flecked minutely with brown, the spines tipped 
with black : base of the abdominal joints heavily marked with black at the sides. 
Lateral foveole of the head distinct, three or four times as long as broad, equal, mo- 
derately deep, the walls abrupt; median and lateral carine of pronotum equally 
sharp and distinct, the latter strongly approximate in the middle of the anterior two- 
thirds of the pronotum; and since they are edged interiorly with yellow, forming, with 
th. yellow line bordering the black band of the head, a clepsydral outline. Length 
of body 919 mm.; of antenne ¢5mm.; of tegmina?5 mm.; of hind femora ?11 
mm. ‘Two females were taken on the Souris River. : 
10. Arphia frigida: nov. sp—Dark reddish brown; antenne reddish-brown at 
base, infuscated beyond ; tegmina flecked obscurely and rather uniformly through- 
out, but least at base, with small dusky spots; wings pale yellow at base, with a 
moderately broad, blackish fuliginous bent band beyond the middle of the. wing, 
faintly interrupted with pale fleckings on either side of the nervures (though the 
nervures themselves in this part of the wing are blackish), occupying the entire 
space between the two principal veins of the upper area of the wing, from the base 
three quarters the distance to the outer border, but paling next the base, at the 
extremity bent downward and outward as far as the outer border, thence following it 
nearly to the anal angle; beyond the band, the apex of the wing is fuliginous, 
slightly the darkest at the extreme tip; the costal margin is yellowish, tinged with 
dull orange above the transverse portion of the fuliginous band; hind femora indis- 
tinctly transversely fasciate with dark brown ; hind tibiz livid, broadly clouded with 
fuliginous just before the middle and at the apex, dusky at the base, the spines black, 
excepting at base. A pair of minute frontal foveole separate the lateral foveolx of 
the head from each other, and also the vertex from the frontal costa; they are dis- 
tinct, minute, longitudinally quadrate, confluent above, their bounding ridges, as 
well as those of the lateral foveole, punctulate. Pronotum rugose above, especially 
on the anterior half; median carina ‘low, uniform, almost straight, once interrupted ; 
posterior border of pronotum bent at a rounded right angle. Length of body : & 
18;927 mm.; of tegmina: 4 22;925 mm.; of hind femora: 11 4 mm. A single 
female was taken near Wood End in June. I have also a male from, the Yukon 
River, Alaska, collected by the late Mr, Robert Kennicott. 
11. Arphia tenebrosa.—A single male was brought from Souris River. 
12. Hippiscus phanicopterus—A male and two females were taken at Dufferin, 
June 13 and 14, 
13. Edipoda trifasciata.—One female was taken at Wood Endin June. This is 
the most northern locality from which it has been obtained.
