long and slender; scapes not lobulate at the base, straight, reaching nearly J 

 their length beyond the occipital border; funicuU with indistinctly 4-jointed 

 clava; joints 2-5 fully twice as long as broad. Thorax long and slender; 

 pronotum flattened above and obscurely submarginate on the sides. Pro- 

 mesonotal suture distinct. Mesonotum slightly and abruptly raised in front 

 and then sloping backward and downward, with rather uneven outhne in 

 profile, to the short and rather deep mesoepinotal constriction. Epinotum 

 longer than high or broad, its base rising abruptly in front, distinctly convex 

 above and twice as long as the declivity, longitudinally grooved in the middle; 

 the spines acute, directed upward and backward and slightly curved inward; 

 as long as the dechvity and the interval between their bases. Petiole rather 

 small, twice as long as broad through the node, which is shorter than the 

 peduncle, conical above and constricted behind. Postpetiole pyriform, 

 longer than broad, somewhat less than twice as broad as the petiolar node, 

 the node feebly convex anteriorly in profile and distinctly concave behind. 

 Gaster rather large. Legs long and slender. Middle and hind tibiae with 

 distinct but slender spurs. 



Shining; mandibles subopaque, very finely and sharply longitudinally 

 striate. Head coarsely and sharply reticulate rugose, the rugae diverging on 

 the front, those starting from the anterior corners making a sigmoidal curve, 

 bending outward around the antennal foveae, turning inward around the 

 inner orbits and then laterally again. Neck finely and transversely rugulose. 

 Thorax coarsely rugulose like the head but less strongly and more irregularly. 

 Pronotum above smooth and shining in the middle, on the sides finely and 

 longitudinally striate. Base of epinotum strongly and rather regularly trans- 

 versely rugose, the concave dechvity with similar but feebler sculpture; 

 mesopleurae and sides of epinotmn more irregularly punctate-rugose. Petiole 

 and postpetiole smooth and shining, except their ventral surfaces which are 

 subopaque and very finely and densely punctate. Gaster smooth and shining, 

 the basal third of the first segment subopaque and very finely and densely 

 striolate. 



Hairs yellow, coarse, obtuse, moderately long and abundant on the body, 

 much finer and more appressed on the legs, especially on their flexor surfaces. 



Dark reddish brown; legs, including the middle and hind coxae, the tip of 

 the gaster, and the posterior margins of its segments brownish yellow; mandi- 

 bles, neck, sides of pronotum, fore coxae, and antennae red; apical halves of 

 femora infuscated. 



Described from eighteen specimens taken by Professor Gee at 

 Mokanshan. 



This species is very distinct, being quite unlike famelica and geei. 

 In certain respects it resembles A. roihncyi Forel of India and central 

 China and especially its subspecies tipuna Forel of Formosa.
