i Paris, June 15, gave a germination of 39 per cent in July, when
it was not yet thoroly cured, and late in the fall (November)
gave the very satisfactory germination percentage of 87. Two T
— other samples of Kentucky seed, sent to the Station at my re- i·
  quest by Mr. J. S. VVilson, of Paris, germinated 83 and 87 per T T
cent, respectively. The three samples thus give an average of (
82.6 per cent, which is very good for seeds of this grass. The T. y y
crop was thus reduced by the bugs not so much in quality as in _ l
  quantity, a11d this can be understood as a result of the fact that

;_ ~ DESCRIPTION OF THE PLANT BUG ·  
_ The adult pest is about 0.32 inch in length by about 0.08 l
I. inch in width, being thus somewhat slender. The sides are i A.
H nearly parallel. , The four wings of the adult are carried laid ’  
I. Hat along the back. Antennae and legs are relatively long. The ; I
B strong beak when not in use is carried folded back beneath the  
g `body and reaches about to the bases of the third pair of legs.  
3_ ' Two forms of the female occur, a long-winged and a short- i
lg winged. In the former and in the male, the wings extend to or  
BS. slightly beyond the tip of the abdomen; in the short—winged fe-  
ly male tl1ey cover only the front two-thirds or il11‘G€·f()lll"[llS of this  
V9, ‘· part of the body. The young (nymphs) are wingless. (
