riorlj \ nt «-[iii:u- slender, the soap* king a little beyond the an- 



terior half oi the lateral border ol tin- bead; funicular joinl 

 broad, joints 7 and 8 longer than broad; baaal joint oi elava | as long as the 

 terminal joint. Pro- and mesonotum in profile verj convex, rounded, hemi- 

 spherical, without promesonotal suture, from above hali as broad as the I 

 as broad as long, narrowed behind to the deep rnesoepinotal constriction. 

 Epinotum short, its base straight in profile and shorter than the sloping 

 declivity, w ith a pair of erect, Battened teeth which are as long as broad at the 

 base and curved forward and outward. Their ba* - are continued as a pair 

 of anteriorly converging ridges on the base of the epinotum and posteriorly as 



a pair of parallel ridges down the sides of the declivity. PetiolfiJ Dode small, 



angular in profile, with both the anterior and posterior Blopes straight, its 



ventral outline evenly convex. Postpetiole large, three time- as broad a- the 

 petiole, as long as broad, slightly narrower in front than behind, evenly 

 rounded and convex above, hut not higher than the petiole. Gaster smaller 

 than the head, with Btraight anterior border. Legs rather long. 



Very smooth and shining, Mandibles with a few small, very sparse punc- 

 tures, their bases striated. Sides of clypeus, cheeks, and space on each Bide 

 medial to the frontal carinas longitudinally striated. Mesopleurae and 

 epinotum subopaque, the former very finely punctate-rugulose. 



Hairs golden yellow, very sparse, erect, and rather long on the dorsal sur- 

 face of the body, on the legs more numerous, fine and appressed. 



Red; gaster and legs yellow. 



Worker minima. Length, 1.5-1.8 mm. 



Resembling the large worker, except in the small size of the head, which is 

 more distinctly longer than broad, with more convex sides and more rounded 

 posterior angles. Eyes smaller, a little in front of the middle of the sides. 

 Mandibles, pro- and mesonotum less convex, the apical margins of the former 

 oblique, with more acute teeth. Teeth of epinotum very small and Blender, 

 directed Upwards. 



Sculpture, pilosity, and color as in the larger worker. 



Described from nine maxima and two minima workers from Mokan- 

 shan (Gee). Some of the former are almost intermediate in the size 

 of the head between the two extremes. I am not certain that the 

 largest really represent the maxima of this species which is closely 

 related to such small Pheidologetons as nanus Roger of India and 

 especially to yanoi Forel of Formosa.

Many soldiers and workers from Soochow and Mokanshan; females 

 and males from Soochow and between Shanghai and Soochow (Gee).
