little beyond one-third the length of the supra-anal plate, the apical 

 half of the furcula densely punctate; cerci subequal, little more than 

 twice as long as broad, slightly sulcate and emarginate below. Supra- 

 anal plate of male finely punctate all over.

"Genae and sides of pronotum varying from yellowish testaceous to 

 dark griseo-fuscous. Markings of vertex of pronotum variable, vertex 

 generally showing a dark mottled stripe widening posteriorly and a 

 lighter linear area between this and the eye. Sometimes the vertex is 

 marked with irregular diffusion of fuscous. Dorsum of pronotum dark 

 griseo-fuscous, sometimes uniform and noticeably darker along the median 

 line, or rarely lighter in this positio,n." 



This species is very closely related to M. spretus Uhl., the famous 

 Rocky Mountain locust. It is sometimes spoken of as the lesser migra- 

 tory locust and is known to fly for considerable distances. In size and 

 color it is also very closely related to M. f emur-rubrum, the common red- 

 legged 'hopper, but may be readily distinguished by the notch in the 

 apical portion of the subgenital plate and the blunt tubercle or swelling 

 on the mesosternum in front of the lobes. This species becomes so numer- 

 ous at times as to be of real economic importance. The habits of this 

 species and the method of control are very similar to some of the other 

 species and will be discussed later. 



M. atlanis may be found all over the state, and is found in all kinds 

 of vegetation, cultivated as well as uncultivated fields. The writer has 

 noticed females of this species oviposit as late as November 15.
