wheeler: CHINESE ANTS. 531 



posterior border of the head is scarcely emargiiiate in the middle, the occipital 

 furrow is distinct but there is no median furrow on the front. The inner 

 border of the mandibles bears eight denticles, which diminish in size basally 

 where they are very small. Of the three apical teeth the most basal is large, 

 rectangular and slightly longer than broad. Petiole convex in front and 

 behind with short, stout, apical spine. The body is smooth and shining, 

 except the front which has fine, posteriorly fanwise diverging rugae, and the 

 mesonotum and dorsum of the epinotum, which are finely, transversely 

 rugose. The pronotum, mesopleurae, and sides of the epinotum are entirely 

 smooth and shining like the head. The posterior portion of the latter is very 

 indistinctly and sparsely punctate. There are only a few hairs and they are 

 on the gula, ventral surfaces of the mandibles, and posterior portion of the 

 gaster. Color brownish red; mandibles slightty paler; gaster of the same 

 color as the thorax but slightly darker above behind the first segment. Legs 

 brownish yellow. 



A single specimen from Mokanshan (Gee). 



This subspecies is both smaller and smoother than any of the 

 described forms of vionticola and seems to be a northern and probably 

 depauperate race. Forel has described two additional varieties, 

 formosac and major, of the same species from Formosa, but both have 

 the posterior portion of the head distinctly striated, especially major, 

 which measures 13. .5-13. 6 mm.
