250 FAMILY VI. ACRIDID^E. THE LOCUSTS. 



braska, and south and southwest to central Florida, Oklahoma 

 and northern Texas. It is not recorded from Canada, nor from 

 Michigan, but it doubtless occurs in the latter State. 



In Illinois Hart reports the proportion of orange-winged in- 

 dividuals to be much greater than that noted above for Indiana 

 specimens, but states (1907, 258) that in a sand region in south- 

 ern Wisconsin, where hundreds were seen every day, but a single 

 orange-winged specimen was observed during five weeks' collect- 

 ing. He therefore concludes that the yellow-winged form is that 

 of the more arid environment. On the contrary, in New England, 

 only the yellow-winged form is known, and Fox (1914, 496) states 

 that he has never seen in the field a red or orange-winged speci- 

 men in Pennsylvania or New Jersey, and adds: "The usual ex- 

 planation that the red-winged phase is due to greater humidity is 

 difficult to harmonize with the almost exclusive prevalence of the 

 yellow-winged type in our region, which is much more humid than 

 the States west of the Appalachians." Of its habits in Virginia 

 he says (1917) : ''In a general way xanthoptera shows greater 

 latitude in its choice of habitats than sulphured. Both are dry- 

 land forms and flourish only in untilled areas, but xanthoptera 

 does not show any marked preferences for woodland associations ; 

 occurring as frequently in campestral stations as in sylvan. In 

 open country it usually occurs in old waste fields and pastures 

 over-run with coarse grasses and weeds, and the grassy tangles 

 bordering cultivated fields ; in woodland surroundings it frequents 

 the low, briery scrub and coarse herbage of clearings and borders." 



The Ocdipoda carinata Scudder (1869, 306) I regard as only a 

 form of A. xanthoptera, with a slightly higher and more arcuate 

 crest of pronotum, more finely granulate prozona and more slen- 

 der hind femora. It has been recorded from Illinois by Thomas 

 (1880) and McNeill (1891) and from Minnesota by Somes. Speci- 

 mens from Kansas distributed as carinata by Snow are undoubt- 

 edly the same as Indiana xanthoptera. 



107. ABPHIA GRANULATA Saussure, 1884, 67. Southern Yellow-winged 



Locust. 



Size and form of A. sulphured. Color of that species, the tegmina of 

 nales, as there but less often, with a dull clay-yellow stripe along part or 

 all of the overlapping dorsal field, and those of females often, of males 

 rarely, thickly sprinkled with paler spots; wings with dark ray near cos- 

 tal margin extending two-thirds to base as in sulphurea ; hind tibiae usu- 

 ally pale with a fuscous ring at basal third and another near apex. Ver- 

 tex and frontal costa much as in xanthoptera, the concavity of the former 

 deeper; foveolae suboval or subtriangular. Median carina of pronotum 

 low, faintly cut but not notched at middle, the entire disk and often the 

 lateral lobes and occiput thickly covered with small tubercles or granules.
