over limited areas. Both as regards the regions inhabited, 

 its habits, and life -history, the common Red-legged Locust 

 (Melajioplus feniur-7-uhrum Har.) hardly differs from the 

 last species and is often found m company with it. It is 

 non-migratory, however, and though its injuries are thns 

 entirely local, they are often of considerable importance. 



Records of locust-j^lagues in California date back as far

 and in the last inyasion of 1885 this species outnumbered 

 all others seven to one. Resembling the last two species 

 in size and markings, the habits and life-history of this 

 species are also supposed to be similar to them, though 

 they have not as yet been thoroughly studied. 



Together with the last species the Pellucid Locust 

 {Camnula pellucida Scud.) has been largely responsible for 

 the losses occasioned by locusts in California, and has also 

 been found in New England, but not noted there as 

 specially destructive.
