served the very close resemblance of the worker of CE. brischkei to 
this recent species which is common in India, Polynesia and Anstralia 
and is known to use its larvae in spinning the silken nest which is 
attached to the leaves and branches of trees. The worker of smaragdina 
differs from brischkei in having mnch longer and more slender 
legs and antennae and a rauch more slender petiole with the node 
more angular and well behind the middle of the segment. The first 
funicular joint is nearly twice as long as the second, the frontal 
carinae are more nearly parallel and the mesoepinotal constriction of 
the thorax is longer and more pronounced.

Worker (Fig. 56). Length nearly 6 mm. 
Differing from CE. brischkei as follows: The body and appendages 
are much less slender, the mandibles shorter and more convex at the 
base, the eyes somewhat larger, the head broader and more deeply 
excised behind. The antennal scapes reach less than 1 / 3 their length 
beyond the posterior corners of the head; funicular joints 1 and 2 are 
not more than 3 times as long as broad, the first a little longer than 
the second; terminal joints thicker, the penultimate joint as broad as

long. Thorax stouter, the pronotum as broad as long, the mesonotum 
but little longer than broad, the base of the epinotum long and not 
very convex. The petiole is as broad as long, with a low rounded 
node which has a faint, but distinct longitudinal impression in the 
middle. Gaster from above nearly circular, scarcely longer than broad,
