found in considerable numbers. The flight of the specie- is dis- 

 tinctive; taking wing with great rapidity, individuals Hy very low 

 for a short distance, but evince great wariness and often have to be 

 approached a number of times before it is possible to come within 

 striking distance. Only infrequently was the flight accompanied 

 by a sound, this being a faint clicking whirr like that occa- 

 sionally produced by individuals of the western T. cya7ieipennis. 

 The granite surfaces were for the greater part stained to a blackish 

 hue and the majority of specimens were exactly of this coloration, 

 a few were paler, matching similar areas of rock surface, while occa- 

 sional specimens were mottled with greenish and these exactly 

 blended with the lichenose areas of rock." 



The disk of the wings varies in the present species from light dull 

 green-yellow to the palest green-yellow. 



Except for the color variation mentioned above, little variation is 

 to be found in the present series. Extremes of tegminal length 

 measure as follows: males 18.6 to 21.4 mm., females 22.8 to 27.2 mm. 



In Georgia the species is known only from White Oak Gap and 

 Flat Rock on Sand Mountain, outside of the localities given above. 

 The distribution of this species is highly discontinuous, as it is con- 

 fined to bare rock surfaces; it has not been taken in the Appalachians 

 north of Highlands, North Carolina.
