314 FAMILY VI. ACRIDIDJE. THE LOCUSTS. 



marshes. When flushed it rises quickly and with a fluttering 

 noise, makes a long, wavering, jerky flight, and alights upon the 

 bole or branch of tree or shrub, a fence, or some other object some 

 distance above the earth ; seldom, if ever, settling on the ground. 

 If then approached, it dodges around the object upon which it 

 rests, much as does a squirrel under the same circumstances. 



In Florida AS', duicricana has been taken by me at all points 

 where collecting has been done. About Dunedin, it is frequent 

 throughout the winter, especially so in old fields, and on Hog Is- 

 land it occurs among the coarse grasses, within 50 feet of the 

 strand. When flushed in the pine woods it often alights on the 

 boles of the trees eight to 20 feet above the ground. It has been 

 recorded many times from all parts of the State, including the 

 southern keys. Adults are to be found any month in the year, but 

 nymphs are scarce in winter. It is often called the "clickety bug" 

 by the southern negroes, a name given it on account of the rustling 

 noise made by the wings in flight, which, however, is not a true 

 stridulation. 



Of the distribution of the American locust Scudder (1899c, 

 474) has written: "Excepting 8. percgrina, which has crossed 

 the ocean and colonized another world, /Sf. aiucricana is the most 

 widely distributed member of the genus, and merits its name, 

 ranging as it does from North America east of the Great Plains 

 and south of about latitude 40 ; through the West Indies, Mexico 

 and Central America to South America, where it occurs as far as 

 Colombia in the west and Argentina in the east, though the rec- 

 ords of its occurrence in South America are few. North of north 

 latitude 40 or thereabouts, sporadic cases of its appearance are 

 recorded, notably in Massachusetts and southern Ontario; these 

 are doubtless accidental visitants, flying from their proper home 

 farther south." Since Scudder's writing, it has been recorded 

 from Connecticut by Walden (1011, 108), and extreme northern 

 Iowa by Somes (1014, 68), so that taking its northern Indiana, 

 Michigan and other records into consideration, it is liable to be 

 found anywhere in our territory south of north latitude 45.
