may be found Hippiscus phcenicoptera, a large species, with 

 red underwings. By the middle of July these have passed 

 away, their places being filled by swarms of Camenula pel- 

 lucida, associated with Trimerotropis verriculata, and one or 

 two others. During August and September the fields fairly 

 swarm with locusts, prominent amongst them being Melono- 

 plus femur-rubrum, Stenobothrus curtipennis, Encoptolophus sor- 

 dida, while on dry bank and roadsides, Dissosteira Carolina 

 may be found in equal abundance. By the middle of Octo- 

 ber nearly all have disappeared, but a few specimens of 

 Melanoplus and Stenobothrus linger until the autumnal frosts 

 put an end to their existence.
