shorter than the second and third together, joints 2-8 more than twice as long 

 as broad; ckib very slender, a little shorter than remainder of funiculus, with 

 the first joint longer than the second and the terminal shorter than the other 

 two together. Eyes larger and convex, situated in front of middle of sides of 

 head. Pronotal humeri obtusely angulate. Mesonotum projecting behind 

 horizontally as a broad, lamellate process, concave at middle of tip. Base of 

 epinotum sloping, a httle longer than declivity. Epinotal spines long, erect, 

 bifurcate above, with the anterior projection short and angular and the 

 posterior elongate and acute. Petiole long and slender; node narrow, cuneiform 

 above, angulate at sides and concave at middle. Postpetiole much broader 

 than petiole, broadest in front of middle and narrowed and sloping behind. 

 Legs long, femora stout. 



Head and thorax feebly, the rest strongly, shining. Mandibles with sparse 

 punctures. Head rugosely punctate, with striae which are irregularly longi- 

 tudinal on front and vertex and reticulate on sides, and occiput. Thorax with 

 broken irregular transverse ridges. Epinotum, petiole, postpetiole, gaster, 

 and legs microscopically punctate. 



Fine long hairs moderately abundant on head, body, and appendages. 



Reddish brown to dark brown, with the gaster darker and appendages 

 lighter.

 the distance to occipital corners. Epinotal spines strong, shorter than the

Nests beneath stones and logs. The soldiers and workers are slug- 

 gish in their movements. 



Named after the late Col. Theodore Roosevelt. 



There is considerable variation in size and in the color of the soldiers,

 between the extremes in size and color are intermediate forms. I

 mens. The smaller ones appear identical in structure and sculpture. 



This species is very different from any described Pheidole in the
