distinct base and declivity, though the lower metasternal border is reflected 

 at the articulation with the petiole. Petiole resembling that of the major 

 worker, but even lower, with its dorsal surface more truncated and flattened. 



Sculpture and pilosity much as in the worker major, but the anterior portion 

 of the head not subopaque and punctate, the pubescence on the sides and 

 front of the head replaced by oblique or subappressed, rather abundant hairs 

 and the scapes as abundantly provided with oblique hairs as the legs. 



Black; mandibles, anterior border of cheeks and clypeus, the mesopleurae, 

 sides and posteroinferior border of the epinotum, and the tarsi beyond the first 

 joint, red. Funicular joints 3-9 brownish yellow. 



Described from three major workers and one minor worker taken on 

 the Rambungan River, Sarawak by Prof. Harrison W. Smith, to whom 

 the species is dedicated. It is very distinct from all the Indomalayan 

 Colobopsis of which I have seen specimens or descriptions. Type.
