SUBFAMILY III. LOCUSTIX.K. 395 



mon of the late autumn locusts, frequenting- the borders of open 

 woods, fence rows and roadsides, especially in dry situations 

 where blue-grass abounds. On warm sunny afternoons in Novem- 

 ber, it may often be seen resting quietly on the sides of logs, or 

 the lower part of rail or board fences, and apparently enjoying the 

 sunshine. In the center of the city of Indianapolis I have often 

 noted it along the edges of walks, though it is less common on the 

 lawns than its long-winged congeners, femur-rubrum and differ- 

 ential is. It is able to withstand quite severe frosts and has been 

 seen mating as late as November 15. From Florida M. scndderi is 

 known only by a single male taken by Davis at Monticello, in the 

 extreme northern part of the State. 



The known range of scudderi is a wide one, extending from 

 New England west to Minnesota and central Nebraska and south 

 and southwest to northern Florida, Oklahoma and Ft. Worth, 

 Texas. In New England Morse and Scudder have recorded it from 

 Maine, Massachusetts and Connecticut, Morse stating (1SOS, 280) 

 that it is a local but common species, preferring dry hillsides 

 among bushes, roadsides and open woods. It is not recorded from 

 Canada, and in Michigan is known only from Washtenaw Co. 



Lugger (1898, 185) mentions it as uncommon in Minnesota, 

 and Somes records it from only half a dozen localities, stating 

 that there it reaches maturity about August 20, and is most com- 

 mon in open woodlands. Morse (1907, 52) records it from numer- 

 ous localities in Arkansas, Oklahoma and northern Texas, and 

 calls it a '"locally common, even abundant, and very widely dis- 

 tributed species." Wherever M. scudderi occurs it appears to be, 

 as in Indiana, one of the more common of the late autumn locusts, 

 its gray and brown hues serving it well for protection among the 

 fallen leaves, grass stems and other debris of that season. 

 184. MELANOPLUS CAENEGIEI Morse, 1904a, 10. Carnegie's Locust. 



A medium sized species closely resembling scudderi in size and form. 

 General color reddish- in stead of grayish-brown, the postocular black 

 stripe of male more distinct. Frontal costa more deeply sulcate. Disk of 

 pronotum scarcely as wide, its sides subparallel in both sexes, median 

 carina more distinct. Tegmina shorter, usually slightly overlapping. Su- 

 pra-anal plate shorter, its margins less elevated, median sulcus broader, ter- 

 minating at middle of plate. Furcula minute, subcylindrical. parallel, ly- 

 ing straight on the bases of the median ridges. Cerci scarcely longer 

 than their basal breadth, three-fifths as long as the supra-anal plate, thick 

 at base, tapering evenly to the straight apex (Fig. 136, c.) Subgenital 

 plate scoop-shaped, subconical, the apex narrow, rounded or subtruncate.
