The Ants of the Baltic Amber. 
115 
Head small, including the eyes broader than long, with large 
convex eyes and ocelli. Mandibles long, narrow, spatnlate, edentate 
and rather blunt at their tips. Antennse short and slender, 13-jointed; 
scapes bnt slightly enlarged towards their tips and reaching only 
about 7 3 their length beyond the posterior border of the head; joints 
of funiculus decreasing rapidly in length distally, joints 1 and 2 sub- 
equal in length but the form er thicker, so that the first is ab out 3, 
the second about 4 times as long as broad, penultimate joints scarcely 
longer than broad, terminal joint as long as the two preceding toge- 
ther. Thorax large and robust, through the wing insertions more 
than twice as broad as the head, with very large and somewhat 
flattened mesonotum and scutellum and the pronotum so much reduced 
in length as to be invisible when the insect is seen from above. 
Petiole stout, about twice as long as broad, a little broader behind 
than in front, with an angle in the middle on each side and a low 
rounded node. Gaster elliptical, broad and flattened above. External 
genitalia very small, stipites very short, bluntly pointed, volsellse 
longer but not clearly visible. Legs very long and slender, terminal 
tarsal joints and claws large. Wings very large and ample, longer 
than the body. Veins strongly marked, discal cell absent. 
Sculpture and pilosity much as in the worker. 
Color black or dark brown, with paler appendages. 
This species was described by Mayr from 5 worker specimens, 
one each in the Berlin Museum, Berendt, Brischke, Menge and Mayr 
Collections. I have seen 45 specimens distributed as follows : 36 workers 
and 2 males in the Geolog. Inst. Koenigsberg Coli. (B 14166, B 14192, 
B 27279, B 18484, B 14342, B 18747, XXB 1972, B 5254, XXB 1505, 
B 5192, B 5210, XXB 365, B, 18783, B 5421, XXB 1500, B 19059, 
B 18262, B 5324, B 5334, B 5265, B 19760, 8727/447 and 5 without 
numbers), 5 workers in the Klebs Coli. (K 834, K 4449, K 936, K 5117, 
and X 21) and 2 workers (271 and one without a number) in the 
Berlin Museum. B 14192 in the Geolog. Inst. Koenigsberg Coli, 
contains 8 workers in a single block and another large block in the 
same collection (B 14342) contains 4 workers together with 2 specimens 
of a small Colobopsis - like Camponotus, several fragments of miscel- 
laneous ants and debris of various kinds. This mass evidently repre- 
sents a portion of the refuse heap, much like the kitchen-middens 
accumulated by our recent ants in or near their nests. 
I believe that I am not mistaken in attributing the two male 
specimens (B 5421 and XXB 1500) to this species as they agree very 
closely with the male of the recent CE . smaragdina Fabr. Mayr ob-
