part, of Ohio. Through the efForfs of these gentlemen the worm was 

 for the first time connected in our minds with the parent moth, and 

 several parasites were ascertained to infest the species. But beyond 

 these points — important as they are — no discoveries were made. The 

 complete natural history of the species has yet to be recorded. 

 Where facts are wanting theories flourish, and we find that in the 

 Prairie Farmer^ the Illinois Fanner^ the Field Notes and the Ohio 

 Farmer^ some very spirited articles were published in 1861 by Messrs. 

 Walsh, Klippart and Thomas — the controversy between the first two 

 being at times personal and acrimonious. The points of dispute be- 

 tween Messrs. Walsh and Thomas were, 1st, whether the insect 

 winters in the Qg^, or chrysalis state ; 2nd, whether it is single or 

 double brooded — Mr. Walsh arguing for the first of both propositions. 

 From an economic view these points are of vital importance, and 

 though they have not yet been settled by direct observation, I shall 

 endeavor to settle them, as far as it is possible, by deduction from the 

 known facts in the case that bear on them. Before attempting to do 

 so, it will be well to briefly describe the Army Worm in the three 

 states in which it is known. 



[Fig. 20.] tt 'j'ije general color of the full grown worm is dingy 



Iblack, and it is striped longitudinally as follows: On the 

 back a broad dusky stripe; then a narrow black line; 

 then a narrow. white line ; then ayellowish stripe; then 

 a narrow sub-obsolete white line; then a dusky stripe; 

 then a narrow white line; then a yellowish stripe; 

 then a sub-obsolete white line ; belly, obscure green.
