tinged with green. Caudal femora so intensively colored that 

 they are black, with two bands (oblique and extending only over 

 dorsal half of external pagina), a pre-genicular annulus and a 

 ventro-external line in proximal half of buffy, the ventral surface 

 buffy often suffused with greenish glaucous externally and meso- 

 distad. Caudal tibiae greenish glaucous with a post-proximal 

 buff annulus, before (strongly) and after (weakly) suffused with 

 brown. All of the greenish coloration is apparently lost when 

 specimens of this group become discolored and in the females 

 which were not eviscerated the color pattern of the caudal femora 

 is often partly or wholly lost. 



Specimens Examined: 21; 13 males and 8 females.

Melanoplus acrophilus pachycercus new subspecies (PI. XXII, fig. 13) 



Serious discoloration has occurred in the series before us, but 

 the insect is very similar to typical acrophilus in general appear- 

 ance, differing only in being very slightly stockier and in having 

 distinctive male cerci. 



It is probably similarly an inhabitant of mountain forest 

 undergrowth and very local in distribution. Material from the 

 mountains between the type locality, which is the northernmost 

 point known for the species, and southwestern North Carolina, 

 will, we believe, show intergradation and prove the present to 

 be a northern geographic race. 



Type. — c? ; Mountain Lake, Giles County, Virginia. Eleva- 

 tion about 4000 feet. July 18, 1915. (P. P. Calvert). [Acad. 

 Nat. Sci. Phila., Type no. 5537]. 



Generally very similar to the type of typical acrophilus. 

 Tergite preceding supra-anal plate swollen at bases of the very 

 minute, triangular furcula. Supra-anal plate as here described 

 for cherokee but all carinae coarse and very weak. Cercus slightly 

 more than twice as long as proximal width, curved decidedly 

 inward, tapering moderately in proximal half due to the declivity
