52 Unh'crsily of Michigan 



Hancock, however, apparently found Melanoplus walshii 

 rather common at Lakeside ; he reports it, as the synonymous 

 M. hlatchlcyi^ as occurring between the first and the last of 

 August in the same type of habitat occupied by Melanoplus 

 viridipes earlier in the season.

This species far exceeds all others in abundance in this 

 region. It is found nearly everywhere except dn the denser 

 portions of the woods. In the dry, grassy fields and pastures 

 and along the roadsides it flies up in swarms before one at 

 every step in the latter part of the season. Specimens were 

 taken in the open, grassy margins of woodland in the dune 

 and inland regions; in fields of second growth scrub; in sedge 

 and reed marshes ; in moist meadow pastures ; and among the 

 herbaceous growth of mud-bars and pond margins. In the 

 dune region it is found with Melanoplus angustipennis in the 

 beach grass and bunch grass habitats. On several occasions 

 it was very numerous in the beach drift. 



Adults were already common June 20, and were still abun- 

 dant September 9, the latest date on which collections were 

 made. The species was taken at Lakeside by Hancock on 

 September 18.

 of Scudder's revision, but the name is still inquirenda."
