stigmata on its dorsal surface. The epinotum rises suddenly in profile as a 

 very convex, hemispherical mass, with distinct stigmata and subrectangular 

 metasternal corners. Petiole nearly three times as long a,s broad, broadest 

 in front where the node is situated, sides slightly concave from above, the 

 posterior angles in the form of acute teeth. In profile the node is low and 

 rounded, its anterior declivity short and very abrupt, its posterior declivity 

 long, straight, and sloping. Gaster rather large, very convex above, its an- 

 teriorly bulging first segment with an impression on its surface for the accom- 

 modation of the underlying petiole. Legs long and slender. 



Shining; head finely shagreened and less shining than the pronotuln; 

 remainder of thorax subopaque, very densely and indistinctly punctate- 

 shagreened and somewhat glossy. Gaster and legs shining, with small, sparse, 

 piUgerous punctures. 



Hairs yellow; the macrochaetae on the body long, curved, and prominent, 

 absent on the mesonotum, epinotum, and petiole, not very blunt at their tips. 

 Hairs on the legs and scapes delicate, oblique and more abundant. 



Head j'ellowish brown; thorax brownish yellow; somewhat darker and 

 more reddish posteriorly. Legs and anterior three fourths of gaster clear 

 yellow; remainder of gaster dark chestnut-brown, sometimes with the base of 

 the second segment yellow. Antennae somewhat paler than the head; flexor 

 surfaces of the tibiae distinctly infuscated. 



Redescribed from six specimens taken at Mokanshan (Gee). 



This is a beautiful and very striking species, quite unlike any 

 Prenolepis of which I have seen specimens or descriptions. In the 

 peculiar structure of the thorax it remotely resembles P. mjobergi 

 Forel and another Australian species (undescribed) in my collection.
