FAMILY VI. ACRIDIDJE. THE LOCUSTS. 



ed elsewhere in Florida from numerous stations as far south as 

 Ft. Myers. It is mainly a dry-land species, inhabiting the tall 

 grasses and the undergrowth of open pine woods, though some- 

 times found on bunch grass in old fields or the borders of swampy 

 timbered areas. Adults have been taken from mid-July to the 

 last of November. The reddish-brown stripes have in life a pur- 

 plish or rosaceous tinge, and the insect is one of the most hand- 

 some of the Tryxalimp. Its known range in our territory is from 

 central North Carolina and northern Georgia, south and west to 

 Ft. Myers and Dunedin, Fla., Mobile, Ala., and Hattiesburg, Miss. 

 West of the Mississippi it has been recorded by Morse from Wil- 

 burton and Shawnee, Okla., and by McNeill and Scudder from 

 Dallas, Texas. As first pointed out by Morse (1907, 27) M. vigi- 

 lans Scudder (1899a, 43) is a synonym; as is also the J/. rostrata 

 McNeill (1897, 207) from Mackay, Oklahoma.

This species is included in this work on the strength of the 

 Illinois records by Hart (1907, 231) and Vestal (1913, 20). Hart 

 reported it as taken with M. Invittata (i)iacclungi) near Havana 

 and Teheran; August 18 Sept. 2, being "found among long bunch 

 grass between the sand dunes." The types of Thomas were from 

 northeastern New Mexico, and its known range extends from 

 northwestern Illinois west to eastern Montana and south and 

 southwest to central and western Texas, southern Arizona and
