In the present species the height of the pronotal crest, measured 

 vertically from the dorso-caudal angle of the pronotum, is moderately 

 variable in all of the material in our collections, the extremes measur- 

 ing as follows; males 1.4-2 mm., females 1.5-2 mm. The minimum 

 of this measurement is approached by the majority of specimens. 



The present species is widely distributed through the pine woods 

 of Florida and extreme southern Georgia and is an inhabitant of low, 

 flat country. On Mixon's Hammock a specimen was taken on the 

 edge of an oak grove. The insect is known from localities extending 

 from Wilmington, North Carolina, and Waynesville, Georgia, west- 

 ward as far as Thomasville, Georgia, and south to Key West, Florida.
