are of much importance to the Territory, since they form the main sup- 
port of the cattle on our ranges. The grasses of the mountain valleys 
and plains of New Mexico consist principally of the common Gramma 
Grass (Boutelona oligostacliya), together with Stipa comata and Aristida 
purpurea. 
Acridium emarginatum Uhl. — Las Cruces, August 19. 9 • Another 9 specimen 
which I take to be this species, but which has the tegmina much less yellowish on 
sides, was taken in the Grand Canon, July 10. 
Acridium shoshone Thos. — Chares, X. Mex., August 6. 9 . Las Cruces, October 24, 
$ in alfalfa held. A 9 taken in the Crand Canon, July 10, is slightly yellower. This 
species often defoliates the Mesquite near Las Cruces (see Canad. Entom., 1892, p. 
198;. 
Arphia tenebrosa Scudd. — This is a very black species with wing^on oblique basal, 
half bright red. Sept., Las Cruces. 
Arphia teporata Scudd. — Las Cruces, May 9. In alfalfa fields. Not particularly 
numerous. 
Aulocara elliottii Thos. — Very abundant in Johnson's Basin, western Socorro County, 
June 22, on the short native grass which grows in the valley. It occurred in large 
numbers and caused considerable injury to the grass. This was in 1892. Melanoplus 
occidentalis occurred with it, and a specimen of Camnula pellucida was also taken. 
On June 23 (next day) it was found abundant farther west in valleys on the Spring- 
erville road, in New Mexico, near the Arizona line. At Pratt's ranch, just across the 
line in Arizona, we were told that these locusts had destroyed the garden and held 
crops there the previous year (1891), and had eaten up the grain fields for three 
consecutive years (1889 to 1891, inclusive). The ranchmen had concluded to try it 
another year, for the fields were in grain at that time. The abundance of the locusts 
at that date, June 22-23, indicated that the crops would probably be destroyed for 
the fourth consecutive year. On July 31, 1892, 1 was told at Eamah, a small Mormon 
settlement east of Zuni, in New Mexico, that for the four years previous the locusts 
had eaten up the wheat crop in that vicinity. The alfalfa crop had also been repeat- 
edly destroyed. The description given me indicated the above species, and probably 
MeJanoplus occidentalis. Camnula pellucida was very probably associated with them. 
Aulocara scudderi Bruner. — Chaves, New Mexico, August 6. 9 • 
Bootettix argentatus Bruner. — This beautiful species I have found only on Larrea. 
Young, May 13; adults, July 17. Las Cruces (see Can. Ent. 1892, p. 198.) 
Camnula pellucida Scudd. — In swarms in the fields and along roadsides at the AI 
ranch of the Arizona Cattle Company, 9 miles from Flagstaff, Ariz., near the San 
Francisco mountain, July 16, 1892. Both sexes. A $ specimen is paler and quite 
greenish instead of brownish. A small $ , much paler than the other specimens, 
was taken in Johnson's Basin, N. Mex., June 22, along with Aulocara elliottii and 
Melanoplus occidentalis mentioned above. Also a $ from the Continental Divide, in 
Valencia County, N. Mex., August 2. 
Circotettix shastaiius Bruner (?). — Flagstaff, Ariz. Common near town, and espe- 
cially so just at the north of it. July 3 to 16. This is a blackish locust, which 
stridulates more shrilly in the hot sun than any species I have ever had the pleasure 
of listening to. 
Conozoa texana Bruner. — Las Cruces, May 19 and September 2. Both sexes. 
Eather common. 
Dactylotum lougipennis Bruner MSS. — Grand Canon, 3,000 to 5,000 feet below rim 
at Hance's, July 9-10. This is a beautiful species, marked with bright red on the 
head, from which a median red vitta extends down the pronotum, with red on 
pleura and on abdomen near extremity. Wings light green, rest more or less yel- 
lowish. Hind tibiae bluish. 
Dactylotum variegatum Scudd. — A number of specimens collected by W. J. Howard
