previously from Sulphur Springs (2,000 feet) and Mount Pisgah 

 (4,500 feet), North Carolina, and the high country of northern 

 Georgia, is all intermediate in character. Hancock has based his 

 "variety" Tettigidea medialis on such material from southern Illinois, 

 Missouri, Tennessee and Louisiana. We strongly question the 

 Louisiana material being intermediate, for the material before us 

 from that State is typical of T. lateralis lateralis. The uselessness 

 of a name for intermediates between weakly defined geographic 

 races does not require comment. 



Material taken in heavy forest near streams or in swampy places 

 shows a strong predominance of the abbreviate phase (Weldon and 

 Lake Waccamaw, North Carolina; Thomasville, Georgia 39 ). A female 

 before us from Charlotte, North Carolina, has the wings abnormally 

 produced, reaching 3.8 mm. beyond the caudate pronotum and 14 mm. 

 in total length. The present insect is distributed everywhere through 

 grasses and herbage of meadow, forest, swamp and marsh, usually 

 found most numerous in and about damp situations. Of typical series 

 before us 90.6% is caudate, this percentage excluding the three series 

 discussed at the beginning of the paragraph. Besides the 367 

 individuals of the present species recorded above, we have before 

 us 223 other specimens previously recorded from the southeastern 

 United States and from as far west as Louisiana. 



The largest series of intermediates before us (Washington, District 

 of Columbia; Asheville, North Carolina) include a majority of speci- 

 mens having the dorsal surface of the pronotum paler in coloration 

 than the lateral lobes, ranging in different specimens from snuff brown 

 and russet through clay color to cream color. Three of these speci- 

 mens have the caudal femora broadly banded, four have a large spot 

 in a similar position, while a number have the entire caudal femora 

 of the same shade of the dorsum of the pronotum. Nearly half of 

 the remaining large series of the present insect are unicolorous black- 

 ish brown, while almost all of the other specimens have the dorsum 

 of the pronotum only slightly paler, usually unicolorous but occasion- 

 ally somewhat mottled, and the caudal femora wholly uniform or 

 inconspicuously marked. All of the males have the face and ventral 

 portion of the lateral lobes of the pronotum nearly or quite clear white.
