SUBFAMILY II. OEDIPODIN.E. 281 



Jarman Gap, Va., Aug. 1 (Fox). This locust was, strangely to 

 say, placed as a variety of snxatile by Morse, but in color, in struc- 

 ture of facial costa, and especially in form and height of median 

 carina of pronotnm, it is very distinct. Aside from the structure 

 of the median pronotal carina it is much closer to Itolli than to 

 saxatlle, not only in form and size, but also in color and general 

 facies. Moreover, it is not a saxicolous species, restricted to bare 

 rock surfaces, as is saxatile, but has the same haunts as bolli, as 

 is shown by the notes of both Morse and Fox. The former ( 1904, 

 36) states that at the typical locality, Wytheville, Va., he "found 

 it plentiful locally on a thinly grassed, gravelly hill-slope, accom- 

 panied by its congener, ~bolU, and exactly matching in coloration 

 the purplish-red iron-bearing fragments of rock and soil on which 

 it made its home." Fox (1917) says that: "At Jarman Gap it 

 occurred in considerable numbers in a closely grazed grassy pas- 

 ture on the summit of a ridge, while at Monterey it was common 

 on the higher and steeper slopes, on cleared but untilled rocky 

 ground close to the margin of the woods, frequenting bare, thinly 

 grassed ( Danthonia) or briery areas. In all places it was asso- 

 ciated with ASf. l)olll." 



If plan uni is a variety of anything it must be one of bolli, but 

 the characters as above set forth in the key and description are 

 deemed sufficient to raise it to specific rank. There is a possi- 

 bility that it may have been originally a hybrid of bolli and saaea- 

 tile, partaking somewhat of the characters of both. Aside from 

 the localities mentioned it is recorded only from Lehigh Gap, Pa. 

 (Rclin, 1902c), under the name of Triinerotropis citrina Scudd. 



122. SPHARAGEMON WYOMINGIANUM (Thomas), 1872, 462. Mottled Sand 



Locust. 



Smaller and more slender than our other eastern species. General 

 color pale yellowish- or pinkish-brown, everywhere sprinkled and spotted 

 with darker brown or fuscous; face ash-gray or yellowish, sprinkled with 

 minute darker spots Antennae fuscous at tip, paler toward base. Sides 

 of pronotum with two indistinct dusky bands, the upper in the place of 

 the lateral carinse on prozona. Tegmina with three transverse bars of 

 fuscous spots, the dorsal field often brownish-red. Wins similar to those 

 of l)0lli. the median black band narrower toward the anal angle which it 

 reaches. Hind femora pale brown or gray, with traces of four fuscous 

 cross-bars; within sulphur-yellow, with three or four more or less com- 

 plete black bars, the two basal ones often united. Hind tibia? coral-red 

 or pinkish, paler at base; spines with extreme tips black. Vertex, viewed 

 from above, about as broad as eye, median carina usually evident but 

 faint. Eyes of male larger and more prominent than usual. Pronotum 

 with disk flat on metazona, somewhat sloping on prozona, slightly angu- 

 late in front, acute-angled behind; median carina high, compressed, arched
