THE GREEN-STRIPED LOCUST: REMEDIES. I97 



tipennis (Harris). Of the latter, Tetfix cucullata (Burm.), T. triangu- 

 laris (Scudd.), T. granulata (Kirby), shown in Fig. 59, and T. ornata 

 (Say) are also New York species. Dr. Harris seems to record two 

 broods of the last-named species in his statement, that of his Tetrix 

 sordida — a synonym of T. ornata, he had taken individuals both in 

 May and September. 



In all cases in which large numbers of a species of the Acrididce are 

 observed to hibernate in the larval stage, such hibernation may be re- 

 garded as presumptive evidence of two generations annually — of a 

 spring and autumn brood. 



Remedies. 



For the remedial measures to be employed against this species when 

 it occurs in unusual and destructive numbers, the agriculturist is re- 

 ferred to the First Annual Report of tlie United States Entomological 

 Commission, where the various remedies and devices available against 

 the Rocky mountain locust, are discussed at length, in chapter xiii of 

 70 pages. 



[Additional Note. — A remedy that gives promise of being a 

 most excellent one against the grasshopper visitations that occur in the 

 Middle and Eastern United States, has been published in the Pacific 

 Rural Press of July 4, 1885. The results attending its use in the pro- 

 tection of vineyards and orchards in California have been of a very sat- 

 isfactory character. If future experiments substantiate the claim made 

 for its efficient operation, it will prove to be one of the most valuable 

 insecticides thus far given to our fruit-growers and gardeners. It is as 

 follows, as communicated by Mr. D. W. Coquillet, to whom appears to 

 belong the credit of its discovery: 



It consists of a mash composed of bran, arsenic, sugar and water, the 

 proportions being one part of sugar, one and one-half parts of arsenic 

 and four parts of bran, to which is added a sufficient quantity of water 

 to make a wet mash. A common washtubful of this mash is sufficient 

 for about five acres of grapevines. Fill the washtub about three-fourths 

 full of bran, add six pounds of arsenic, and mix it thoroughly with the 

 bran; put about four pounds of coarse brown sugar in a pail, fill the 

 pail with water and stir until the greater part of the sugar is dissolved. 

 Then pour this sugar-water into the bran and arsenic, and again fill the 

 pail with water and proceed as before until all of the sugar in the pail 

 has been dissolved and added to the bran. Now stir the latter thoroughly 

 and add as much water as is necessary to thoroughly saturate the mix- 

 ture, and it is ready for use. 



Throw about a tablespoonful of this mixture upon the ground beneath 

 each vine infested with grasshoppers; and in a short time the latter will 

 leave the vine and collect upon the bran and soon commence feeding 

 upon it. Those which are upon the ground six or eight feet from the
