﻿OF THE STATE ENTOMOLOGIST. 85 



We have a locust here which has in some places occurred in considerable numbers, 

 and Pome 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, Un. 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. 



Toward the end of July the unfledged insects did an immense 

 amount of damage to the cotton and other crops of Georgia and South 

 Carolina. The papers were full of graphic accounts of their destruc- 

 tion, and editors not only very generally took it for granted that 

 they had to do with the western spretus^ but Mr. T. P. Janes, Commis- 

 sioner of Agriculture for Georgia, in his circular No. 27, supposed they 

 were the same. Specimens which he subsequently sent me, however, 

 at once revealed their true character. 



The damage done by some of the more common locusts that occur 

 over the country, is, let me repeat, sometimes very great, especially 

 during hot, dry years. In some of the New England States their 

 ravages have, in restricted localities, fairly equalled those of the vora- 

 cious spretus of the West. But while a few of them, under exceptional 

 circumstances, develop the migratory habit, they none of them ever 

 have, and in all probability never will, compare to Catoptenus spretus 

 in the vastness of its migrations and in its immense power for injury 

 over extensive areas. 



Whenever we hear of locust flights east of the Mississippi, we may 

 rest satisfied that they are not of our Rocky Mountain pest, and are 

 comparatively harmless. 



DOES THE FEMALE FORM MORE THA^T ONE EGG-MASS ? 



Whether the female of our Rocky Mountain Locust lays her full 

 supply of eggs at once, and in one and the same hole ; or whether she 

 forms several pods at different periods, are questions often asked, but 

 which have never been fully and definitely answered in entomological 

 works. It is the rule with insects, particularly with the large number 

 of injurious species belonging to the Lepidoptera, that the eggs in the 

 ovaries develop almost simultaneously, and that when oviposition 

 once commences, it is continued uninteruptedly until the supply of 

 eggs is exhausted. Yet there are many notable exceptions to the rule 

 among injurious species, as in the cases of the common Plum Curculio 

 and the Colorado Potato-beetle, which oviposit at stated or irregular 

 intervals during several weeks, or even months. The Rocky Moun- 

 tain Locust belongs to this last category, and the most casual exami- 

 nation of the ovaries in a female, taken in the act of ovipositing, will 

 show that besides the fully formed eggs then and there being laid, 

 there are other sets, diminishing in size, which are to belaid at future 

 periods. This, I repeat, can be determined by any one who will take
