This is the most generally and uniformly distributed grasshopper 

 of the State, so far as collections from the locahties listed enable one 

 to judge. In numerical strength its only superiors are the dominant 

 species of Melanojjlus, namely, M. atlanis in the Coastal Plain and 

 Piedmont sections and M. femur-ruhrum in the Appalachians. It 

 occurs in a great variety of habitats, but shows a stronger predilec- 

 tion for campestral stations than for sylvan surroundings. It is 

 common in cultivated fields (wheat plats, clover, and timothy pas- 

 tures, etc.) as well as old waste lots and pastures. 



The winter is passed in the nymph stage. At Charlottesville the 

 earhest adult males were found April 4 (1915), the earliest females 

 April 12 (1914). The eggs laid by the spring brood of adults begin to 

 hatch toward the end of June (June 25, 1914) and adults of the second 

 brood first appear by the middle (July 1 1 , Norfolk) or end (July 20, 

 Charlottesville) of July. Adults of this brood continue to develop 

 during the remainder of the summer and early autumn, and survive 

 until the beginning of winter. It is possible that the earhest maturing 

 individuals of second generation may lay eggs from which hatch the 

 smaller of the winter-surviving nymphs, but this point needs experi- 

 mental verification before it can be accepted as a fact.
