tolticus Sauss. Four specimens, three taken in Rist Canon near 
Laporte, June 26, 1898, (Ball.); and one taken along the river 
near Ft. Collins 6-12-gy. (Gillette.) 
mm\m stai. 
bivittata Serv. Common over the entire eastern portion of the State 
to some distance within the foothills. This species seems to 
prefer the higher ground and is often abundant upon hill-tops. 
We have recorded specimens from Ft. Collins, Laporte,Wind¬ 
sor, Greeley, Orchard, Julesburg, Wray, Rockyford and Holly. 
We have taken adults at Ft. Collins as early as July 10th 
and as late as Sept. 10th. They doubtless continue much 
later. 
neomexicana Thom. Phis specimen seems to cover about the same 
ground as the preceding though it is much less abundant 
We have specimens taken at Ft. Collins, both within and 
outside of the foothills, and also a few specimens taken at 
Rockyford, Holly and Nepesta. Our captures have all been 
made during August and September. 
ACmOPHITUS Thomas. 
hirtipes Say. We have found this species most common in the 
gulches of the outer foothills and upon the dry hillsides. It 
probably occurs in small numbers over most of the plains of 
the eastern portion of the State. At Ft. Collins adults begin 
to appear about the last week in June. All our specimens 
have been taken before the last of August. Most of them 
are uniformly green in color but several individuals have a 
lighter shade, varing from light green to almost white upon 
the elytra and pronotum. Upon the elytra the lighter color 
is so distributed as to leave the green, for the most part, in 
round or oval blotches. 
Specimens from Ft. Collins, Laporte, Livermore, Dutch 
George’s, Wray, Greeley, Boulder, Golden, Las Animas and 
Coolidge, Ks. July 7, ’02 all adult and eggs mature at La¬ 
porte. (Ball.) 
ERITETTIX Bruner. 
navicula Scudd. Specimens answering to the discription of this spe¬ 
cies seem not to be specifically distinct from tricarinatus. 
Perhaps Caudell is correct in thinking all the Colorado forms 
are navicula. See “note on Orthoptera, etc.” by A. N. Cau¬ 
dell, Proc. U. S. National Museum, Vol. xxvi.
