Specimens have been taken at Ft. Collins, Windsor, Gree¬ 
ley, Merino, Jnlesburg, Orchard, Manitou, Nepesta, Rockyford, 
Lamar, Holly and Trinidad. 
HYPOCHLORA Bru n ner. 
alba Dodge. This is a common species over the plains region of 
Colorado where its food plants occur. The two species upon 
which it chiefly occurs are Artemisia frigida and A. ludovi- 
ciana (white sage). It is not readily seen among the leaves 
of these plants which it closely imitates in color. The colors 
vary from a pale yellowish green to a rusty brown. 
A large number of specimens in the College collection 
vary between 15 mm. and 19 mm. in length in the males, and 
between 21 mm. and 25 mm. in length in the females. The 
short pointed elytra measure between 4 mm. and 5 mm. in 
length in the males and between 5 mm. and 6^2 mm. in the 
females. So far as known this insect attacks no cultivated 
plant. 
Adults have been taken as early as July 8, 1898, at Ft. 
Collins and as late as Oct. 14th, 1901, at the same place. It 
has also been taken at Denver, Boulder and Jnlesburg, Colo¬ 
rado, and at Kimball, Nebraska. 
CAMPYLACANTHA Scudder. 
olivacea Scudd., seems to occur in the south-eastern portion of the 
State only. Several specimens were taken Sep. 8, 1898, at 
Holly, and othersat Trinidad four days later, all by E. D. Ball. 
This grasshopper is said to be partial to sunflower (Hc/i- 
anthus ), and to lamb’s cpiarter (Che nopod in w), and Bruner 
suspects it of feeding upon beets also. 
The 21 males in the College collection vary -between 18 
mm. and 22 mm. in length and the tegmina vary between 5 
mm. and 7 mm. The 28 females vary between 22 mm. and 29 
mm. in length and the tegmina vary between 5 mm. and 8 
mm. 
HESPEROTETTIX Scudder. 
coloradensis Brun. (See description in article following this). 
gillettei Brun. (See description in article following this). This seems 
to be a rare species in Colorado. After considerable searching 
I took five specimens from Gutierrezia euthcimiee at Glenwood 
Springs Sep. 15th, 1903. The collection also contains speci¬ 
mens from Delta, Grand Junction and Rifle, all points upon 
the west slope. July 13th to Sep. 16th.
