The Ants of the Baltic Amber. 



39 



Eyes minute and very near the anterior corners of the head. Mandibles 

 with three or four larger apical and several very minute basal teeth. 

 Clypeus moderately convex, its anterior border straight, except in the 

 middle, where it has a slight, rounded projection. Antenuc'e slender; 

 scapes not reaching beyond the posterior corners of the head; first 

 funicular joint about three times as 

 long as broad, joints 2 — 4 as long 

 as broad, joints 5 — 10 distinctly 

 longer than broad and gradually 

 increasing in size; terminal joint 

 large, nearly as long as the three 

 preceding joints taken together. Tho- 

 rax in profile nearly straight above, 

 compressed laterally, especially in 

 the meso- and metapleural region, 

 i)roadestthroughthepronotum,which 

 is somewhat longer than broad ; 

 mesonotum transversely elliptical, 

 a little broader than long; meso- 

 epinotal suture very distinct; base of 

 epinotum submarginate on the sides 

 about as long as the declivity, into 

 which it passes through a rounded 



angle. Petiole as high and as broad as the epinotum, in profile with 

 straight and perpendicular anterior and posterior surfaces and evenly 

 rounded node. First gastric segment somewhat narrower than the 

 second. Legs of the usual shape. 



Body finely punctate-rugulose and shining, the punctures on the 

 gaster very fine and more superficial than those on the head and thorax. 



Body and legs with sparse, suberect hairs, most distinct on the 

 dorsal surface of the former, shorter and more reclinate on the latter. 

 The head seems to be covered with short pubescence. 



Black; gaster more reddish, especially the sides and ventral 

 portion of tlie first segment. 



Described from a single, well-preserved specimen,without a number, 

 in the Geolog. Inst. Koenigsberg Coll. There can be little doubt that 

 this is the worker of the species which was based by Mavr on male 

 and female specimens only. This worker shows that P. atafia is distinct 

 from the living P. coardata. Concerning the former Mavr said: „Diese 

 Art, besonders aber das Weibchen, stimmt mit der jotzt lebenden 

 Ponera contracta Latr. so sehr iiberein, daC ich nicht imstande bin,
