260. Hexagonia nigrita, Van de Poll, Notes from the Leyden 

 Museum, 1889, p. 247. 



Karin Gheba 900-1100 m. 



There are two examples of this large species, measuring 12 

 millim. Van de Poll gives 10 V2~l-'- ^/2 niiH™. for his specimens 

 which came from Java and Sumati'a. The species is remarkable 

 for the narrowness of the thorax and the very slight trace of 

 angle on the margin and also for the head being rather less 

 quadrate (more narrowed posteriorly) behind the eyes than in 

 the other species.
