200 PROCEEDINGS OF THE ACADEMY OF [April, 



four females of which but two have distinct indications of these bars, 



which are entirely absent in one (Tybee Island). The color of the 



caudal tibiae varies in the extent to which olivaceous green replaces 



part of the blackish purple, in the "rubiginosa" specimens warm 



browns replacing the olivaceous green. All of the Wrightsville 



series is striped, as is the case with the material from Florence, 



Ashley Junction, Augusta, Albany, Sandfly, Atlantic Beach, South 



Jacksonville and Ortega; the series from Tybee Island includes one 



brownish female and that from Cumberland three brown females. 



The latter all have the tegmina more or less distinctly multi-maculate 



with fuscous, while the similar phase female from Tybee Island is 



almost entirely plain. 



The structural differences between the color phases follow the 



lines discussed in the preceding summary, while the extremes in 



size in the two sexes measure as follows:

It will be seen from this that such size variation as is found can 

 be considered purely individual and not geographic. All of the 

 measured specimens are in the extreme striped condition, except 

 the maximum male, which has the stripe stopping at the caudal 

 margin of the pronotum and the general color quite brownish. 



The range of this striking species in the southeastern States is 

 chiefly confined to the country below the fall line, i.e., the sands and 

 gravels of the coastal plain and peninsular Florida, as it is apparently 

 rare and local in the Piedmont region (Thompson's Mills, Georgia, 

 and Druid Hill Park, Baltimore, Maryland). 



On Tybee and Cumberland Islands and at Wrightsville the species 

 was found among strand bushes and the low oaks, palmettoes, etc., 

 there growing; at Florence, Augusta and Albany it frequented high 

 weeds in or near fields, generally of cotton, and at Ashley Junction 

 it occurred in long-leaf pine woods. It was common only occa- 

 sionally, being generally but few in number and very frequently 

 associated with alutacea.
