robust, 12-jointed; scape not reaching the posterior corner of the head; 

 all the funicular joints, except the first and last, distinctly broader 

 than loDg. Thorax of the usual shape. Petiole as high as the epinotum, 

 higher than long and about 1^2 times as broad as long; its anterior 

 surface somewhat concave, its upper surface rounded and convex and 

 passing through an obtuse angle into the flattened posterior declivity; 

 the sides rounded. Gaster of the usual conformation. All the legs 

 with pectinated spurs; middle and hind pairs each also with a pair 

 of small simple spurs. Middle tibise and metatarsi short, with numerous 

 stout bristles on their extensor surfaces. 



Mandibles coarsely striate -punctate; head, thorax and petiole 

 finely and densely punctate; gaster smooth, apparently. 



Hairs long, suberect and scattered, rather uniformly distributed 

 on the head, thorax and gaster; shorter, more abundant and appressed 

 on the legs. Antennae with only a few short, erect hairs near the 

 bases and at the tips of the scapes. 



Dark brown or black; legs somewhat reddish: wings yellowish, 

 with brown veins and stigma. 



This is evidently a true Euponera of the subgenus Trachymesopus, 

 on account of the short and bristly middle tibia and metatarsus and 

 the character of the spurs on the middle and hind tibife. 



In addition to one of Mayr's types (No. 640/10 277) I have seen 

 eighteen specimens from the Geolog. Inst. Koenigsberg Coll., namely, 

 Nos. Ill B 250, E 5478, B 5064, B 19 074, B 18 632, B 19 093, B 5450, 

 B 19 027, B 5222, B 5253, B 18 594 and seven without numbers; and 

 three specimens from the Klebs Coll., namely K 1094, X 11 and A 140. 

 All the specimens bear wings and all are in amber of such similar 

 color and texture, and are in such a uniform state of preservation, 

 with more or less of the gaster, usually its tip, enveloped in large 

 bubbles or masses of white substance, that I am inclined to believe 

 that all came originally from the same locality and even formed part 

 of the same nuptial flight.
