The Ants of the Baltic Amber. 85 



legs and antennae are much stouter and shorter, the scapes do not 

 reach beyond the posterior margin of the head and the funicular 

 joints 2 — 10 are scarcely longer than broad. The sculpture is only 

 superficially like that of mesostcrnalis and vexiUarius. The mandibles 

 are very sparsely punctate, the clypeus sharply longitudinally rugose, 

 the umbilicate foveolae of the head, though deep, are further apart, 

 so that they are separated by smooth spaces, except on the cheeks; 

 on the thorax the foveolaj are confined to the dorsal portion of the 

 pronotum and base of the epinotum and are absent on the pleura?. 

 On the pro- and mesonotum they are rather shallow. The petiole is 

 also indistinctly foveolate or coarsely reticulate-rugose posteriorly and 

 on the sides. The gaster, scapes and legs are finely and densely 

 shagreened and very sparsely punctate. Hairs erect, very sparse, 

 distinct only on the body. Color black, with red appendages or red 

 throughout. 



I have seen 13 specimens of this species, 8 in the Geolog. Inst. 

 Koenigsberg Coll. (XXB 1194, B 11757, XXB 1038 and 5 without 

 numbers), 4 in the Klebs Coll. (K 5101, K 4782, K 4206 and K 2613) 

 and one in the Wm. Haren Coll. (415). Most of these are in a 

 beautiful state of preservation and show the finest details of structure 

 and sculpture very clearly.

 Mayr described the worker, female and male of this species in 

 considerable detail. Concerning the male there was some doubt in 

 Mayr's mind, but he referred it to this species, because it agreed 

 with the worker in size and sculpture. The worker is very much 

 like that of D. sculpturatus in size and shape but the sculpture is 

 very different. The head, pro- and mesonotum are smooth and finely 

 shagreened and lack the deep umbilicate foveolae of D. sculpturatus^ 

 although the cheeks are coarsely and sparsely punctate and the pro- 

 and mesonotum also have a few scattered punctures. The meso- 

 epinotal constriction and petiole are longitudinally rugose and the base 

 of the epinotum is covered with shallow foveolae, especially on the 

 sides. The sculpture of the female is very similar but the base of 

 the epinotum is deeply foveolate, except in the middorsal region 

 where there is a smooth, sub-elliptical area.
