The surface seems to be smooth, however, except the epinotum and 

 petiole, which are coarsely rugose. Gaster covered with scattered 

 piligerous punctures. 



Hairs rather abundant, investing the body and legs, suberect 



on the former, more reclinate 

 on the latter. Pubescence on the 

 antennae long and conspicuous. 

 Wings hairy. 



Body black ; legs dark brown ; 

 wings with pale brown veins and 

 stigma. 



Described from two well- 

 preserved specimens, one (No. 157) 

 in the Brussels Museum and one 

 (without a number) in the Geolog. 

 Inst. Koenigsberg Coll. There 

 can be little doubt that they be- 

 long to this species, of which Mayr 

 described the female from a single 

 specimen in the Menge Coll. 

 There is another specimen of this 

 sex (B 1309) in the Geolog. Inst. 

 Koenigsberg Coll., but it is rather 

 poorly preserved and in an unfortunate position, though it shows a 

 great deal of the sculpture of the right side of the body. Tr.is 

 sculpture agrees very well with Mayr's description. The worker phase 

 is still unknown. 



Genus Electroponera, gen. nov 



A single worker specimen (B 18 994) in the Geolog. Inst. Koenigs- 

 berg Coll. differs so greatly in general habitus from any Ponerine 

 genera known to me that I am compelled to make it the type of a 

 new genus and species, although the legs, gaster, front of the head 

 and much of the remainder of the body are hidden in a very opaque 

 white film. The block of amber containing the specimen has been 

 mounted, moreover, in a large balsam cell, so that it is impossible to 

 see much more than is represented in Fig. 6. Ectatomma seems to 

 be the most nearly related genus. The head is subrectangular, with 

 rather rounded sides and posterior angles and feebly excised posterior 

 border. The mandibles are large and of the usual form, but their 

 teeth, if they have any, cannot be seen. The frontal carinse are appar-
