SUBFAMILY IV. CONOCEPHALIXJE. 583 



, leaping a shorter distance when disturbed, and frequent- 

 ing the surface of the ground rather than the steins of the tall 

 prairie grasses among which it makes its home. It will probably 

 be found, by close search, to inhabit most of the few remaining 

 patches of raw prairie in the western part of the State. 



The known range of saltans cannot be definitely stated as it 

 has heretofore been confused with the next species. Scudder's 

 types were from the Platte River, Nebr., and its natural home and 

 center of distribution is probably on the prairies of the middle 

 west, extending from western Indiana north and west to Mandan 

 and Hillsboro, N. Dak., Livingston, -Mont., and Ma niton, Col., 

 and south and west to Thomasville, Ga., Dallas, Texas, and 

 Springer, X. Mex. Long-winged examples from Dallas are in 

 the Cambridge collection. It appears to be xerophilous in hab- 

 its, as it occurs mainly on dry upland prairies and sandy bar- 

 rens. The JT. tnodestum Bruner (1891, 57) from Nebraska, and 

 the -V. tirniatum Redt. (1891, 520) are synonyms. 

 273. COXOCEPHALUS VIBIDIFKONS sp. nov. Green-faced Grasshopper. 



Shorter and more compact than saltans. Pale bluish-green, fading to 

 dull greenish-yellow, the face immaculate; median stripe of vertex and pro- 

 notum paler brown than in saltans, the yellow stripe below less prominent ; 

 that on abdomen vague or wanting. Fastigium but slightly ascending, its 

 sides subparallel, but slightly rounded, apex scarcely as wide as basal 

 joint of antenna?. Pronotum as in saltans. Tegmina of male reaching 

 nearly to middle of abdomen; one-fourth longer, better developed, with 

 tips more narrowly rounded in both sexes than in saltans. Cerci as de- 

 scribed in key and Fig. 189, e, their apical portion conical, not at all twist- 

 ed, incurved or flattened within near tip as in saltans. Ovipositor shorter 

 a little stouter and with a less evident upward curve than there. Length 

 of body, $, 1113, 9, 12.514; of pronotum, $ and 9, 2.83.2; of teg- 

 mina, $, 4.5 5, 9, 3; of hind femora, $ and 9, 10 12; of ovipositor, 

 9.512.5 mm. 



Toronto, Out., Aug. 10 (Walker) ; Central Park, Long Island, 

 N. Y. Sept. 8 (Dai'is). This species is very distinct from saltans 

 by the characters given in key and description. Comparisons have 

 been made with the types of both saltans and its synonym, mod- 

 est u in at Cambridge and Philadelphia. The male in the Scudder 

 collection from Red River Settlement, Man. mentioned by him

 under C. saltans is a specimen of riridifrons. 



Walker (1904a, 340) took the Toronto specimens above men- 

 tioned Aug. 9 Sept. 8, at High Park in company with Mclanojrtns 

 dairxoni (Scudd.). They were found in open grassy uplands on 

 sandy soil, where they were plentiful among Jerse}"-tea, sweet
