borhoods where the grasshoppers were taken. This species has 
been found fairly common about its food-plant. Upon being 
disturbed the hoppers jump in among the bunches of 
weeds and fall to the ground where they remain motionless 
for a time and are found with some difficulty as their color 
blends readily either with the food-plant or the ground. 
The males vary between 14 mm. and 16 mm. and the 
females between 16 mm. and 22 mm. in length. The short 
elytra of the males vary little from 2 ]/ 2 mm. and those of the 
females vary little from 3 ^ mm. in length. Twenty-five 
males and 32 females examined.

plagosus Scudd. A few specimens of this species were taken at 
Delta, Colo., July 13, ’oi. They were fairly common on 
Sarcobatus sp. (greasewood), which was growing abundantly 
on seepage ground about the town. (Gillette.) 
turnbulli Brun. This is a common Species over the plains region of 
Colorado east of the foothills. Its chief food-plants are species 
of Atriplex and Russian thistle. It has been seen feeding 
upon Cleomc where its common food-plants were very scarce. 
Atriplex expansa ) A. canescens and white sage, Eurotia lana/a , 
have been specially noted as food plants of this insect. 
We have taken this species at the following points in 
Colorado: Ft. Collins, Livermore, Julesburg, Sterling, Gree¬ 
ley, Ft. Morgan, Pueblo, Nepesta, Rockyford, Las Animas 
and Salida. The last named point is the only one any dis¬ 
tance within the foothills where we have taken this species 
and only occasional specimens could be found there. 
The Colorado specimens range rather larger in size than 
the types described by Prof. Bruner. The large number of 
specimens in the College collection measure as follows: Males 
between 17 nun. and 20 mm.; females between 17 mm. and 
25 mm. The elytra vary somewhat in length but in nearly 
all cases they exceed the tip of the abdomen in both sexes. 
We have taken several females with short elytra, about 7 mm. 
in length, but have taken no short-winged males. 
Adults have been taken from June 16 (Rockyford) to 
October 8 (Ft. Collins). The earliest that adults have been 
taken at Ft. Collins is June 26. 
At the latest date mentioned, Oct. 8, many of the females 
still had immature ova of the second crop. (Ball.) Fourteen 
females were dissected Aug. 19th and only three seemed to 
have deposited their first batch of eggs. (Ball.)
