COLLECTED IN BOENEO, ETC. 79 



Gren. Typhlatta. 



Mandibles triangular; eyes obsolete; flagellum 9-jointed; petiole of 

 the abdomen formed of 2 nodes. 



The above characters are those of the worker of the species ; 

 probably an examination of the other sexes would present other 

 very distinctive generic characters, particularly in the neuration of 

 the wings: the palpi I have not examined.

 abdomine glaberrimis ; antennis tarsisque rufo-piceis. 



Worker. Length 2 lines. Black ; the head glassy-smooth and shining ; 

 ovate, with the posterior margin of the vertex truncate ; in some 

 examples, an indistinct castaneous spot at the sides of the head, in 

 the usual situation of the eyes ; the antennae ferruginous. Thorax 

 elongate, compressed at the sides ; very smooth and shining anteriorly, 

 with a delicate striation in the middle, the metathorax being finely 

 rugulose ; the tarsi rufo-piceous. Abdomen : ovate, very smooth and
