F/\'I(/ locuxtx.—In August, Sep- tember, and October from among the coarse diteh grasses and those of swamp and waste places come the rasping sounds and almost con- tiiuious l)uzz of the lield locusts. Not much attention has been paid to these long-horned grasshoppers or locusts. In ordinary seasons they are not prone to wander from the ditch banks, but when the differential prevails, they are forced into the crops in search of food. In and 1899 considerable damage was done. The prevalence of a species of Orchelimum may be imagined when in certain sections of the Delta, particularly near Mound Landing, Miss., hundreds of acres of dry cotton stalks were found to contain numbers of eggs in every branch and twig (see lig. 19 showing- general appearance of punctured stalks and position of exposed eggs). These eggs were also found abundant in the tassel stalks of corn in widely distributed fields. The eggs hatch during the latter part of May and continue until June 20. Moisture has nuich influence upon hastening incuba- tion and hatching. In cages the stalks of cotton were moistened every few" days, and after each dampening the young emerged more numerously. The exact number of molts was not determined. After molting the young devour the cast skin and fre- quently they have been found devouring one another. Maturity is reached very ir- rgularly owing to thn to thirty days after r(>aching the adult, and winters in the egg- condition. In 1899 OrcheJiinnm agile was a real t>nemy to fotton,.
