 Sintang, 1 cf (Goedhuis). 



This specimen belongs to the forma priodonta, 

 and as it measures only 45 mm. in length, 

 it agrees in size with the specimens from 

 Banka alluded to by Leuthner {I. c. p. 472).

The cf from Nanga Raoen , which measures 

 (the mandibles included) 27 mm. in length, 

 does not show the well-defined longitudinal 

 impression on the lateral margins of the 

 prothorax which is present in higher de- 

 veloped specimens, and, moreover, the central 

 tubercle of the front of the head is obliter- 

 ated in this specimen. The cT from Mt. 

 Liang Koeboeng, which has, with mandibles, 

 a length of 45 mm., shows these characte- 

 ristics very clearly.
