Locust Ravages East of the Mississippi. 205 



Such reports as these very naturally confirm the unsci- 

 entific in the idea that the locust plague of the West, or 

 so-called " Kansas grasshopper," has overstepped the limits 

 entomology ascribes to it, and is upsetting the conclusions 

 which I have come to. The same swarm passed over 

 Oxford in the same State, in a southwesterly direction, 

 and fortunately that veteran and well-known apiarian, the 

 Rev. L. L. Langstroth, who has not forgotten to be a close 

 observer, had specimens sent to me. They proved to be 

 the American Acridium already figured and described on 

 page 101, (Fig. 15). It has a wide range, hibernates in 

 the winged condition, and not only differs in size and 

 habits from the Rocky Mountain Locust, but entomologi- 

 cally is as widely separated from it as a sheep is from a 

 cow. It is a species common over the country every year, 

 and during exceptional years becomes excessively numer- 

 ous and acquires the migratory habit, its wings being long 

 and well adapted to flying. As I learn from Dr. S. Miller, 

 of Franklin, it passed in swarms over part of Johnson 

 county, Missouri, late in September ; and it was every- 

 where abundant in 1876. 



The following extracts from letters of correspondents 

 refer to this species : 



I send you by Mr. Shaw a small package containing specimens 

 of locusts, destructive about Chattanooga and in all Eastern Ten- 

 nessee. They strike me as nearly allied to the Rocky Mountain 

 Locust; fly with the same noise and shine of wings, in large shoals, 

 but are larger. — [Dr. G. Engelmann, Warm Springs, N. 0., Aug. 29, 

 1876. 



We have a locust here which has in some places occurred in 

 considerable numbers, and some people think it the same as the 

 one which has produced so much damage in the West. This I 

 doubt, as it is evidently a native species. — [E. M. Pendleton, Prof, 

 of Agriculture, Univ. of Ga., Atlanta, Ga., Sept. 14, 1876. 



The American Acridium visited us on the night of November 

 21, (Saturday.) A rain fell during the night. Cambridge City, 

 Indiana, was also visited by them on the same night. — [Herschel I. 

 Fisher, Eastham College, Richmond, Ind.
