The Ants of the Baltic Amber.

figured to show the peculiar, nmbilicate punctures covering the head 
and thorax. These punctures, however, are somewhat too large in 
the figure. Mayr’s description is, on the whole, very accurate and 
enables one to recognize the species easily. The antennae are 10-jointed, 
the eyes a little in front of the middle of the head, the petiole is not 
pedunculate in front and the femora and tibise are distinctly incras- 
sated, the middle and hind pairs of the latter being without spurs. 
The hairs are absent on the legs, but long, suberect and moderately 
abundant on the head, thorax, pedicel, gaster and anterior surfaces of 
the antennal scapes. The funiculi are pubescent. The gaster is 
apparently opaque and shagreened or finely punctate, with larger, 
more scattered, piligerous punctures. All the specimens are reddish 
brown. Length about 2,6 mm.

I have seen ten specimens of this peculiar 
little ant with 9-jointed antennse, five in the 
Klebs collection (K 4248, with two specimens 
in the same block of amber, K 1698, K 1682, 
and K 820) and five in the Geolog. Inst. 
Koenigsberg Coli. (B 18306, B 18227, B 18179, 
1003/143 62 and one without a number). It 
resembles the members of the paleotropical 
genera Myrmicaria and Pristomyrmex in form 
and sculpture, but the worker of Myrmicaria 
has only seven and Pristomyrmex has eleven antennal joints. The 
resemblance to Myrmicaria was noted by Mayr, who has described 
the species snfficiently.
