Scarcely any size variation is apparent over the distribution of 

 the present species. Males in the series before us range in length 

 from 21.5 to 27 mm., females from 31.5 to 40 mm. Several specimen- 

 from southern Georgia show a considerable reduction in the pronotal 

 crest, which might, confuse them with A. granulata, were other 

 differential characters, which separate these two distinct species, not 

 carefully observed. The height of this crest, measured vertically 

 from the dorso-caudal angle of the pronotum, is variable in all of 

 the series now under consideration, extremes measuring as follows: 

 males, 2 to 2.7 mm., females, 2.3 to 3.4 mm. The great majority of 

 specimens approach more closely the maximum in this measurement . 



The specimens of palest coloration have the ventral surface of the 

 body very dark, which portion of the body is almost black in the 

 normal type of this insect; in A. granulata, this surface is normally 

 very pale, only occasionally weakly suffused with brown. 



The present species was found in dry situations, particularly in 

 more open woodlands (long-leaf and short-leaf pine, pine and oak or 

 only deciduous trees), in fields along the edge of forests and occa- 

 sionally in grassy fields; on Stone Mountain, Georgia, a single speci- 

 men was found on the bare granite rock surface at the summit. 



South of northern Florida, the species is known from but one 

 record, Orange City Junction, Florida.
