ARKANSAS. 



Bentonville, Benton County. — I have not. — [J. W. Williams.] 

 CarroUton, Carroll County. — No. — [John L. Sims. 



COLORADO. 



Colorado Springs, El Paso County. — Cannot answer from personal observation. — [H. 

 McAllister. 



Denver^ Arapahoe County. — Yes. No. 3. In 1874, 1875, and 1876 they laid their eggs 

 very thickly on my farm and in its immediate vicinity, three years in succession, and 

 in the same breeding-spots. — [C. L. Campbell. 



Fort Collins, Laramie County. — For three years, on my farm, have they propagated 

 luxuriantly. — [R. Q. Tenney.

 the same locality, but whether in the same ground exactly I cannot sav.— [H. W. 

 Pollitz. 



Greeley, Weld County. — The eggs of the locust have been thickly laid in this vicinity 

 for two consecutive years. In the fall of 1875 and cf lci76 eggs were laid, acd in the spring 

 of 1876 and of 1877 the young hatched in such numbers as to destroy, or to be able to 

 destroy if left alone, crops in many parts of this valley (Cache Le Poudre) and on 

 the Saint Vrai, and Boulder Creek, in Boulder County. I speak from personal observa- 

 tion.— [G. B. Hight. ■ 



Howardsville, San Juan County. — In certain warm, sandy spots along the Animas 

 River, I have noticed eggs laid and locusts hatch out for three successive seasons. Per- 

 haps, however, they were not true migratory locusts.

Saguache, Saguache County. — No. — [W. B. I'elton.
