Dark reddish brown; mandibles, corners of clypeus, antennse, 
tibise and tarsi paler and more yellowisb. 
Described from two specimens in the Klebs Coli., K 775 (type) 
and K 1093. The former is broken at the petiole and has the gaster 
tnrned upside down. Thongh in clear amber, the lower snrface of the 
head and thorax and dorsal surface of the gaster are somewhat ob- 
scured by a white film. The latter specimen is more decomposed. 
There can be no doubt that this species is a true Liometopum, 
thongh the thorax is longer, less convex above and with a more dis- 
tinct mesoepinotal constriction than in any of the recent species. The 
pubescence is also much shorter than in these forms, but its feebler 
development may be merely apparent and due to the effect of the 
medium in which the specimens are embedded.
