just in front of its articulation with the first gastric segment. Gaster 
and legs of the usual shape. 
Mandibles coarsely striato-punctate. Head opaque, finely reticulate 
punctate; the cheeks indistinctly longitudinally rugose in front. Pro- 
notum with coarse, arcuate rugse, concentric with its hind margin; 
mesonotum, mesopleurse, base and sides of epinotum more finely 
longitudinally rugose; the rugse on the epinotal declivity being trans- 
verse and continuous with the longitudinal rugse on the sides. Petiole 
coarsely longitudinally rugose. Postpetiole and gaster smooth and 
shining. 
Hairs sparse, erect; most conspicuous on the mandibles, clypeus, 
upper surface of the body and lower and apical surfaces of the gaster; 
sparser and less conspicuous on the legs. 
Color black; covered in great part with a silvery air-film. 
Described from a single specimen (X 8) in the Klebs Coli. 
This species may be readily distinguished from all the other 
amber species by its beautiful sculpture and from all except S. ocellata 
Mayr by possessing ocelli.

This is the largest of the species of Sima described by Mayr, 
the worker measuring 7,2 — 9,4 mm. Like the preceding it possesses 
ocelli. The first funicular joint of the antennse is shorter than the 
second and third joints together. 
I have seen only two specimens, Mayr’s type (No. 204/3856) in 
the Geolog. Inst. Koenigsberg Coli, and one, without a number, but 
labelled „ Myrmica yon Brqnsart“ in the Berlin Museum. The latter 
specimen measures only 6 mm and is in the midst of a brown cloud. 
The three ocelli, however, are very distinct.

Two workers in the Klebs Coli. (K. 944 and K. 929) are 6 mm 
in iength and agree very closely with Mayr’s description of this species, 
which is characterized by the absence of ocelli, in having the man- 
dibles broader at the masticatory border than at the base, and in having 
the first funicular joint of the antennse shorter than the two succeeding
