8 SYNOPSIS OF THE GENUS CHLOROTETTIX 



In addition to these states it has been reported as occurring in 

 Pennsylvania, Iowa, Washington, Florida and Maine. These 

 records give the species a wide north and south distribution, 

 covering the eastern half of the United States, and extending 

 across the northern part from the Atlantic to the Pacific oceans. 



Chlorotettix tergatus var melanotus DeLong. 



Chlorotettix tergatus var melanotus DeLong, Tenn. Sta. Ent. Bull., 17, p. 84, (1916). 



Differs from typical tergatus by having a slightly more rounded 

 vertex, a distinctly blacker color, and the plates of the male are a 

 little broader at the tip. Length, 7 mm. 



The structural characters are very similar to the preceding, 

 except that the vertex in the specimens at hand is slightly shorter. 



Color: Black in appearance, but in reality very dark green, 

 eyes black, light margined. Pronotum with a large black spot 

 behind each eye. Elytra with costal margins and apex smoky 

 subhy aline. 



Genitalia: Agreeing with tergatus except that the male plates 

 are a little broader and more strongly rounded. 



The specimens which were given this varietal ranking were 

 collected by the author in Tennessee during the summer of 1915 

 and are now in the author's collection.
