Thorax oblong-ovate, with a few large scattered shallow punctures : 

 the articulations of the legs and the tarsi ferruginous. Abdomen 

 deeply constricted between the first and second segment, the apex 

 rufo-testaceous ; the node of the peduncle incrassate, subquadrate, 

 rather widest behind ; the entire insect is sprinkled with pale hairs, 

 which are most dense on the abdomen, particularly at its apex. 



Worker. This sex is rather smaller than the female, is less pubescent, 

 and with fewer punctures ; the metathorax narrower than the pro- 

 thorax, and obtuse behind ; the eyes are smaller, and, like those of the 

 female, placed forwards at the sides of the head ; the mandibles are 

 similarly toothed ; the colouring does not differ. 



Hab. Celebes ; Menado.

Worker. Length 2^ lines. Pale ferruginous, very smooth and shining ; 

 the eyes small, round, and placed forwards at the sides of the head ;
