72 Psyche [August 



Hairs and pubescence golden yellow, both poorly developed on 

 the head, more abundant on the body and legs; the hairs erect, 

 rather fine, moderately long, the pubescence long and rather coarse, 

 not very closely appressed. 



Ferruginous; legs and antennae scarcely paler; head and mandi- 

 bles a little darker, in some specimens with the occiput slightly 

 infuscated. 



Redescribed from four specimens taken August 30, 1919 by the 

 junior author near Camden, Tennessee. The specimens were 

 found four miles west of the town on a rather dry hillside covered 

 with an open forest of second growth oak. The trees were small 

 and so scattered that there was a ground cover of short wiry dry 

 grass under them, with a few small shrubs and bushes. There was 

 very little ground debris, as the natives seem to keep such picked 

 up for firewood, but under a small stick, perhaps two feet long and 

 three inches wide at its greatest width all four of the ants were 

 found. The stick had evidently been lying in one position for a 

 long time, as it was slightly buried, so that it came up with difficulty 

 and disturbed the earth in loosening. The ants were in the soil 

 beneath the stick, close together, but no evidence of a nest was 

 seen. They were very sluggish and slow-moving, even more so 

 than a few specimens of Stigmatomma pallipes Haldem, which were 

 found in the same habitat. They made no effort to escape, seemed 

 dazed and confused by the sudden disturbance, and one of them 

 when picked up with the forceps and placed in the palm of the hand, 

 feigned death for several seconds, with the antennae drawn close 

 to the head and the legs held tightly against the body.

The phenomenon of vestigial wings in worker ants that other- 

 wise are normal is of interest because of its significance in the prob- 

 lem of the origin of social castes among the Formicidae, and also 

 because of its infrequent occurrence. The recorded captures of 

 workers with wing-vestiges are very few. Wheeler has taken three
