D. tertiarius is by far the most abundant species of Dolichoderus 
in the amber. Mayr studies 87 specimens, Ern. Andre 38. I have 
seen 369 distribnted as follows: 31 workers, 6 females and two males 
in the Klebs Coli. (K 425 K 4266, 
K 1685, K 4207, K 7537, K 3536, 
a 170, etc.); 7 workers in the Wm. 
Haren Coli. (1894, 2412, 2441, etc.) 
and 339 workers, 18 females and 
4 males in the Geolog. Inst. Koenigs- 
berg Coli. (XXB 7131, B 18346, 
B 5358, B 5355, XXB 1034, B 19089, 
B 18443, B 5490, B 5479, XXB 
412, etc.). In addition to all these 
specimens I have examined in the same collection the following types 
of Mayr: 3782/130, 3786/134, 3788/136, 3792/140,3846/194, 7524/238, 
7591/305, 7641/355, 7648/362, 7674/388, 7719/433, 8716/466, 8746/496, 
8751/501, 8764/514, 8768/518, 9778/571. 
It is interesting to note that D. tertiarius is very closely related 
to the only species of the genus now occurring in the holarctic region, 
namely D. 4-punctatus L. of Central and Southern Europe, Asia Minor 
and Siberia, and JD. marice Eorel, plagiatus Mayr and taschenbergi 
Mayr of North America. D. sculpturatus, though more heavily 
sculptured than any of these, also belongs to the same group.

Mayr based this species on two males, which differed from the 
males attributed to D. tertiarius mainly in having longer wings and 
in the more slender antennae. I have seen no specimens of this 
species either in the Klebs or Geolog. Inst. Koenigsberg Coli.
