14. Euphydryas Phaeton—One female was taken at the Lake of the Woods 
between July 15 and August 15. 
15. Phyciodes Tharos—Two males were taken near the Lake of the Woods 
between July 15,and August 15. 
16. Hveres Comyntas—One male was taken at Dufferin and another east of Woody 
Mountain, between the middle of May and the middle of June. These specimens 
differ from eastern types in having the whole upper surface of the wings of a hoary 
aspect, such as generally appears only at the costal edge of the fore wings in eastern 
individuals ; and in the remarkable faintness of the dark spots on the under surface 
of the wings, which bear no small resemblance to those, of lightly marked specimens 
of Cyaniris neglecta. 
17. Eurymus Philodice—A male and a female of the pale form were taken near 
the Lake of the Woods between the middle of July and the middle of August. 
18. EZurymus Eurytheme—A single male was brought home from the Lake of the 
Woods, taken at the same time with the preceding. 
19. Parnassius Smintheus—Two fresh specimens were taken on the summit of the 
Rocky Mts. (near the north-western corner of Montana) at an elevation of from 
6-7,000' on August 9. They were both of the type figured by Edwards, in his plate 
Parnassius II. 
20. Thorybes Pylades—A male was taken at Dufferin. 
21. Thanaos Persius—A female, very badly rubbed, but apparently belonging to 
this species, was taken near the Lake of the Woods between the middle of July and 
the middle of August. 
22. Anthomaster Uncas.—Two males were taken between Woody Mt. and the base 
of the Rocky Mts., between the middle of July and the end of the first week in 
August. 
ORTHOPTERA. 
1. Seudderia curvicauda—A male was taken at Roseau River on August 30, and a 
female in the vicinity of Souris River. 
2. Xiphidium salians—One male and five females, Souris River. Heretofore 
known only from Nebraska and the neighbouring region. 
3. Anabrus purpurascens Four males and four females were taken at West Butte 
July 29 ; in the vicinity of Woody Mt., between June 15 and July 7 ; and in the neigh- 
bourhood of the Souris River. The specimens from the two former places lack the 
mottled markings of the abdomen so peculiar to this species ; there are, however, no 
other distinguishing features. Mr. Thomas, while retaining the generic name Ana- 
brus, refers this species to Thamnotrizon; but wrongly, for it is congeneric with 
A. simplex Hald. the type of the genus. 
4. Caloptenus spretus—Specimens of this destructive insect were brought home 
from Dufferin, the Souris River, the vicinity of the Lake of the Woods, and the East 
Fork of Milk River. In the latter place they were “ forming swarms” on July 16th. 
Mr. Dawson also writes me, that his party “met with great swarms of these insects 
on the high plains north of the Missouri and Milk Rivers, in July, 1874.” 
5. Caloptenus bilituratus—Two females were taken at Souris River. 
6. Caloptenus bivittatus—A single female was taken near the Lake of the Woods, 
July 30. This is the true bivittatus of Say, with which the Acrid. leucostoma of Kirby 
is probably synonymous ; and distinct from the femoratus of Burmeister (the Acrid. 
flavovittatum of Harris), with which all recent authors, myself included, have hitherto 
confounded it ; this species has the hind tibiw glaucous and yellow; in C. femoratus, 
they are red; and the species can be instantly distinguished by these peculiarities. 
1. Pezotettix borealis —A single pair of this species was taken in the vicinity of 
the Souris River. 
8. Pezotettix Dawsoni nov. sp.—Brownish fuscous ; face, sides of head and prono- 
tum yellowish, with the exception of a broad, reddish-brown stripe extending from 
the eyes to the posterior sulcation of the pronotum ; antenne yellowish at the base,
