Wilson — A New Leptothorax 
129 
Mandibles covered dorsally by close-set, longitiudinal striae. 
Clypeus with a dark median carina running from anterior to poster- 
ior border; the remainder of the clypeus more or less longitudinally 
rugulose. Frontal area, frontal lobes, and cheeks rugulose. Re- 
mainder of head, most of the thorax, and the gaster moderately 
shining, with extremely fine punctures. Propodeum and meso- and 
metasternal regions of thorax rugulose, the rugulae of the declivious 
face of^the propodeum transverse. Petiole and postpetiole densely 
and coarsely granulose. 
Body covered by moderately abundant, long, coarse, grayish, erect 
hairs. Antennae with moderately abundant, short, very fine hairs 
over entire surface; many of these hairs on funiculus and a small 
number on scape suberect to erect but the majority appressed. Legs 
with a sparse growth of hairs similar to those on antennae; most of 
these appressed by a scattered few suberect to erect. 
Body dark brown; mandibles, antennae, and legs pale yellow; 
femora infuscated over entire surface except for ends. 
Gynetype. - Differing from the worker in the usual characters 
separating these two phases. Total length approximately 2.7 mm., 
length of alitrunk 0.912 mm., greatest width of alitrunk 0.576 mm., 
length of head 0.568 mm., cephalic index 100. Propodeal spines 
short and robust, their length less than the distance between their 
bases and approximately half the length of the declivious face of 
the propodeum. Sculpturing, pilosity, and color essentially the 
same as in the worker. 
Type locality. - Tuscaloosa, Alabama. 
The holotype worker, the gynetype, and forty-two paratypes 
consisting of seven dealate queens and thirty-five workers were 
collected by the author August 20, 1947, in a small patch of woods 
directly north of Guthrie’s Nursery, which is at the Tuscaloosa 
Memorial Cemetery near the outskirts of the city. 
Additional locality: Elrod, Tuscaloosa Co., Ala. Thirteen para- 
types consisting of two dealate queens and eleven workers were col- 
lected by Barry D. Valentine and the author May 10, 1949, in the 
Sipsey River swamp several miles east of the town. 
The paratypes of this small species vary from the holotype and 
gynetype noticeably in color and size. Callows are pale yellow, 
with infuscated head, gaster, and femora. The other specimens in 
the type series vary from medium to dark, almost piceous, brown. 
The mandibles, antennae, and legs of all are pale yellow, the femora
