SUBFAMILY III. LOCUSTIX.H. 403 



subacute. Extremity of male abdomen clavate, slightly upturned; supra- 

 anal plate triangular with sides convex, apex acute and basal, not very deep, 

 median sulcus; furcula consisting of a pair of slight approximate spines 

 overlying the bases of the median ridges. Cerci compressed, tapering and 

 straight on middle half, with an obscure inner superior basal tubercle, be- 

 yond the middle bent inward a little upward, equal, the tip squarely trun- 

 cate with rounded angles (Fig. 139, c.) Subgenital plate small, longer 

 than broad, slightly elevated and feebly prolonged at apex. Length of 

 body, <J, 23, $, 26.5; of antennae, $ , 13, $, 11; of tegmina, $ and $, 9.5; 

 of hind femora, $ , 13.5, $ , 16.5 mm. 



Scudder's four specimens were from Georgia and Smithville, 

 N. Car. K. & H. (1910, 234) record the taking of 16 additional 

 ones at Lake Waccamaw, N. Car., and St. Simon's Island, Ga., so 

 that it is known only from 20 specimens taken from the four sta- 

 tions in those two states. R. & H. state that "nigrescens is close- 

 ly related to walsJiii, the male differing chiefly in details of dor- 

 sum of pronotum, in the peculiar offset or twist of the distal sec- 

 tion of cercus, and in the more pronounced apex of the subgenital 

 plate. The females are almost indistinguishable, the more deli- 

 cate median carina, straighter ovipositor jaws and less distinctly 

 tapering prosternal spine of nigrescens, being the only tangible 

 distinguishing characters." Their specimens were secured in 

 heavy undergrowth of bushes in short-leaf pine woods, and among 

 dead leaves under live oaks. All known specimens have been 

 taken between August 30 and November 22. 



189. MELANOPLUS WALSHII Scudder, 1897b, 11. Walsh's Locust. 



Size medium for the genus, rather large for the group; form robust. 

 Dark grayish-brown above, yellowish below. Pace dull brown, occiput 

 darker; the usual black postocular stripe rather narrow, often indistinct 

 or wanting, especially in female; disk and lower half of lateral lobes of 

 pronotum and tegmina grayish-brown, often more or less flecked with fus- 

 cous; dorsal field of tegmina pale brown. Hind femora reddish- or yel- 

 lowish-brown, with two cross-bars of black on upper and outer faces, these 

 sometimes indistinct in female; lower face pale or vermilion red, knees 

 black. Hind tibiae red, with a pale ring on basal third, the spines black. 

 Interocular area nearly, male, or fully, female, twice as broad as first 

 joint of antennae, fastigium moderately sloping, broadly sulcate, male, fee- 

 bly concave, female. Frontal costa short, not reaching clypeus, sulcate at 

 and slightly below the ocellus. Pronotum feebly expanding on metazona, 

 disk flat or nearly so, hind margin broadly obtuse angled. Tegmina about 

 one-fourth longer than pronotum, sublanceolate, their inner edges slightly 

 overlapping and tips subacute. Fore and middle femora much swollen 

 in male, hind femora slightly surpassing abdomen, male, reaching base or 

 middle of ovipositor, female. Extremity of male abdomen strongly re- 

 curved. Cerci coarse, heavy, the middle third two-thirds as broad as base, 

 apical third slightly enlarged, curved abruptly inward (PI. Ill, M, com-
