ORTHOPTERA. 



Dissosteira Carolina Linn. [A. N. Caudell]. 

 These grasshoppers are very numerous in the open fields or 

 in the short grass at twilight, but one may beat the bushes and 

 weeds in vain for them. They are protectively colored for their 

 life on the ground by day, and they continue to make use of the 

 same protection for sleep at night, resting on the gray earth or 

 grass of open spaces. 



Hippiscus rugosus vScud. [A. N. Caudell]. 

 This fancy hopper is usually a long jumper, but at 6:30 on a 

 September evening this one made two short flights when I 

 attempted to take him, and refusing to move further he was 

 bottled. 



Arphia corinata vScud. [A. N. Caudell]. 

 This grasshopper seemed to sleep more soundly than most 

 of its brothers. One which was found on July 29, on the under 

 side of an overhanging rock was not awakened by either my 

 strong light nor my fingers' grasp. 



Melanoplus femur-rubrum DeG. [A. N. Caudell]. 



Melanoplus atlantis Riley. [A. N. Caudell]. 

 Melanoplus differentialis Thorn. [A. N. Caudell]. 



These hoppers, like the others, seem to sleep at night right 

 where they live by day. They are usually found at night or in 

 the early morning clinging, head up, to the stems of stalky 

 plants, such as Erigeron, horse-weed, corn, etc. Sometimes 

 they are alert enough to escape when touched, but they are 

 usually languid, especially in the morning. 



Dichromorphia viridis Scud. [A. N. Caudell]. 



Only two observations were made upon this short-horned 



grasshopper, at 9:20 p. m. on June 10, at St. Louis. One insect 



was to all appearances asleep on a grape leaf and the other was 



actually feeding upon a leaf of poison-ivy, Rhus toxycodendron. 



Stagmomantis Carolina Linn. 



Just how or when the devil's horses get their sleep I have 

 never been able to discover, although I have kept many of them 

 under close observation. The males are frequently to be seen
