A NEW STICTOPONERA, WITH NOTES ON 
THE GENUS (HYMENOPTERA : FORMICIDiE)

Among ants collected in Western China during the 
years 1944 and 1945, I have two specimens of a new Stic- 
toponera collected on a high, sharp ridge near Chao Rung 
Mountain and about one and one-half days’ travel afoot 
west of Kuanhsien, Szechuan Province, China. The ele- 
vation was between 5000 and 7500 feet, probably closer to 
the higher altitude, in the zone of dense bamboo growth. 
The ants were taken together in the thin bamboo humus 
at the ridge summit. They moved very slowly, and re- 
sembled our species of Proceratium in their sluggish loco- 
motion and in feigning death at the approach of danger. 
Stictoponera panda new species 
Holotype ivorker. Size, excluding mandibles, 5.2 mm. 
Length of thorax, Weber’s measurement, 1.8 mm. Closely 
related to taivanensis Wheeler in possessing a high 
petiolar node with steep anterior and posterior faces. 
It differs from taivanensis mainly in its larger size, 
broader head (cephalic index, or greatest breadth of head 
expressed as a percentage of greatest length, mandibles 
excluded, is 93) and its different sculpture and color. 
The posterior corners of the head are also a little more 
acute. The eyes small, like those of taivanensis, with 6 
to 8 ommatidia in the greatest diameter, placed near the 
middle of the sides of the head. 
The frontal carinae are slightly farther apart, and the 
longitudinal costulae arising between them and continuing 
back across the vertex are finer and more numerous (four 
distinct costulae in taivanensis, at least twice that many in 
pancla, the more laterally placed costulae with scattered 
shallow pits separating them) . Clypeus very finely longi- 
tudinally striate, its median groove shallow and not 
bounded by definite carinae laterally, somewhat shining. 
The declivity of the epinotum much less distinctly mar- 
gined, the epinotal teeth obsolete, cross-rugae on the face
