stigmata on its dorsal Burfaoe. The epinotum rises Buddenly in profile as a 

 \ii\ convex, hemispherical mass, with distinct stigmata and subrectangular 

 metasternal corners. Petiole nearly three times as Long as broad, broade I 

 in iVmiii where the node is situated, sides Blightly 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 Bloping. Gaster rather large, vbtj convex above, its .ul- 

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

 modation of the underlying petiole. Legs l<»n^ a.nd slender. 



Shining; head finely Bhagreened and less Bhining than the pronotukn] 

 remainder of thorax Bubopaque, very densely and indistinctly punctate- 

 Bhagreened and somewhat glossy. Gaster and legs shining, \\ ith -mall, sparse, 

 piligerous punctures. 



Hairs yellow; the maerochaet ae on the body long, CUTVed, and prominent, 



absenl on the mesonotum, epinotum, and petiple, not very blunt at their tips. 

 Hairs on the le^s and scapes delicate, oblique and more abundant. 



Head yellowish 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. vijobergi 

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