110 Psyche [August 



Much smaller than the female of the typical lineolata, which 

 measures 8-8.5 mm. Head more rectangular and fully as long as 

 broad (broader in lineolata, with more rounded sides and posterior 

 corners). Epinotal spines reduced to stout teeth as in lineolata 

 but shorter and slightly more deflected. Metanotum (postscutel- 

 lum) much less protuberant in profile. 



Surface of body smoother and more shining, covered with fine, 

 sparse, piligerous punctures; mandibles and anterior half of head 

 longitudinally striate, mandibles rather opaque. 



Hairs w^hitish, apparently less abundant than in lineolata, 

 pubescence much the same. Hairs on the scapes shorter and less 

 conspicuous than in the worker. 



Colored like the worker, but the scutellum, an anteromedian 

 and an elongate spot on each side of the mesonotum and the whole 

 gaster brown ; each segment of the latter with a narrow, transverse, 

 dark brown band near the posterior margin. Mandibles red, with 

 black apical margins. 



Male. Length about 3 mm. 



Smaller than the male of the typical lineolata, which measures 

 4-4.5 mm. Head blackish; thorax, petiole and postpetiole choco- 

 late brown; antennse and legs, mandibles and gaster brownish 

 yellow, the dorsal surface of the gaster darker. Wings white, with 

 colorless veins and stigma. Head and gaster somewhat shining, 

 thorax more opaque. Pilosity much less developed than in the 

 male of lineolata. 



Described from several workers and males and a single female 

 taken by Prof. J. C. Bradley in the Okefenokee Swamp, Ga. (type 

 locality). The Rev. P. J. Schmitt sent me many years ago several 

 workers which he had taken at Lake Worth, Fla., and Belmont, 

 N. C. 



C. aikinsoni is very closely allied to C. ashmeadi Mayr and to 

 lineolata subsp. laeviuscula Mayr. Both of these forms have the 

 surface of the body smooth and shining, though in laeviuscula and 

 its vars. clara Mayr and californica Emery the thorax is distinctly 

 sculptured. C. ashmeadi is, however, smaller than athinsoni in 

 both worker and female phases, and the worker has the epinotal 

 spines reduced to stout distinctly incurved teeth. The epinotal 

 spines of the typical laeviuscula are shorter and more sinuate than in 

 athinsoni and the vars. clara and californica are larger, of a very
