based on the melanistic color phase of this species. The name 

 should be synonymized, once and for all, under microptera. 



These specimens exhibit the usual amount of individual variation 

 in size. The Columbia and Social Circle males are typical of the 

 melanistic phase, while all of the Isle of Hope specimens and that 

 from South Jacksonville have decided tendencies in the same direc- 

 tion, the dorsum of the head, pronotum and abdomen, as well as the 

 tegmina and limbs, showing much more blackish than usual in the 

 yellow phase. 



The range of this species is now known to extend north in the 

 South Atlantic States as far as Cabarrus County, North Carolina 

 (Sherman and Brimley). 



The species was taken in pine woods undergrowth (Jacksonville 

 and Isle of Hope), in palmetto "hammock" (Atlantic Beach) and 

 in grass in waste field (Columbia). 



Having personally quite carefully examined the more austral 

 portions of both Carolinas, as well as the greater portion of the State 

 of Georgia, it seems very certain to us that the locality given by 

 Serville in his original description of Acridium coloratum 6i (Chrom- 

 acris colorata of present-day nomenclature) is erroneous. His remarks 

 are "Donne par M. Marc du Havre, qui l'a regu d'une partie de 

 l'Amerique, voisine de la Caroline du Sud." We are convinced 

 that the specimen he had did not come from the eastern United 

 States, but probably was of Mexican origin, as the species is so 

 striking, and so universally secured by collectors who encounter it, 

 that it must make itself quite in evidence in its native habitat.
