species on sweet-grass in Cherokee Park ( Campion's), Feb. 

 27, 1916, at an altitude of 7800 feet. 



Apterous Virgogene. Color light yellowish green, almost exactly the 

 same as the grass leaves upon which it lives ; rather heavily covered 

 with white powder on the ventral surface, but little on dorsum ; general 

 form rather elongate (about 2.60 long by .70 to I broad) ; length 

 of antenna, .85 to .95; cornicles and joints I and 2 and distal 

 half of antennse, dusky to black and powdered throughout; eyes promi- 

 nent and black ; legs yellowish and covered with powder ; tarsi dusky 

 to black ; cauda concolorous with body or dusky, rather bluntly pointed 

 at tip ; beak short, barely attaining 2nd coxae ; cornicles weak recum- 

 bent on the abdomen, concolorous with the body with the extreme tips 

 blackish, in form clavate, in the shape of a baseball bat, but with the 

 small end attached to the body and with the free end rounded off and 

 without any flange present; length, .25 to .30 The entire body is free 

 from hairs, but has a roughness due to what appear to be minute 

 wrinkles. The antenna is 6- jointed, joint 3 being about twice the 4th, 

 and joints 4, 5, 6 and the spur are sub-equal; vertex, strongly convex. 



A striking peculiarity of this species is a rather prominent 

 tubercle on the middle of the hind margin of the dorsal seg- 

 ment preceding the cauda in the apterous form. The tubercle 

 is present but quite small in the alate form. In some examples 

 the third joint of the antenna has from 2 to 4 sensoria which 

 are rather indistinct and possibly only vestiges as the merest 

 outlines are all that can be seen, and these are sometimes more 

 or less broken and irregular. Their location is as shown in 

 Plate XXV, figure 2. The antennae are upon short but distinct 

 tubercles, Plate XXV, figures 5, 6, 7 and 8.
