Wheeler, The Ants of the Bermudas. 



35' 



Female. Length 3.5 mm. 



Head about as long as broad, narrower in front than behind, with a straight 

 posterior border. Clypeus convex, distinctly carinate, its anterior border very 

 faintly emarginate in the middle. Antennal scapes extending about If their 

 length beyond the posterior corners of the head. Front with a transverse ridge 

 between the antennal insertions. Thorax robust, but little broader than the 

 head, flattened above. Epinotum very sloping. Petiole much inclined for- 

 ward, its posterior surface convex, its upper border sharp and feebly notched 

 in the middle. 



Subopaque; thorax, cheeks and posterior corners of the hearl smooth and 

 shining. 



Hairs like those of the worker but proportionally shorter. Pubescence 

 gray, dense, especially on the gaster. 



Dark brown; thorax paler, insertions of the wings, sutures and mouthparts 

 yellow, as are also the tarsi and the articulations of the legs and antennae. 

 Wings grayish hyaline; veins brownish; stigma well-dev eloped, dark brown. 



Fig. I. PrenoUpis kincaidi sp. nov. Male, a, outer; b, median, and <r, inner genital valve. 



Male. Length 2.3 mm. 



Mandibles with an apical and a smaller subapical tooth. Thorax short, 

 robust, with faintly rounded epinotum. Body shining. Pilosity and coloration 

 as in the worker. Legs slender. Wings like those of the female but without a 

 distinct stigma. Outer genital valves long, slender, and distinctly curved in- 

 ward, with a blunt point and abundant but rather short hairs (Fig. i, a). Outer 

 process of median valve digitiform, somewhat bent in the middle and with the 

 papillate surface at its tip; inner process nearly twice as long as the outer, 

 slender and tapering, geniculate near its base and with the papillate surface on 

 its basal half some distance from the slender tip (Fig. 1,6). Inner valve large, 

 apparently twisted, and tapering to a blunt point like that of the outer valve 

 (Fig. i,c). 



Described from four workers, two females and a single male taken 

 from the same colony June 26, 1905, by Professor Kincaid. 



I have described this species as new because I fail to find anything 

 like it among the described American or Old World species of Preno- 

 lepis. In certain respects it resembles P. anthracina of Cuba, but
