Variation in size of these specimens (5 — 6 mm.) is so great as to suggest 
that they may include several closely related species. 
Sima lacrimarum, sp. nov. 
Worker (Fig. 13). Length about 3 mm. 
Head longer than broad, subrectangular, with rounded posterior 
corners and eyes in front of the middle. Ocelli absent. Antennal 
scapes curved; first funicular joint as long as the three preceding 
joints together, joints 5 — 7 broader than long, joints 8 — 10 nearly as long 
as broad. Pro- and mesonotum feebly convex, mesoepinotal constriction 
distinct. Epinotum short, 
as high as long, convex and 
rounded, without distinct 
base and declivity. Petiole 
and postpetiole each longer 
than broad, with a short pe- 
duncle and the node roun- 
ded above and somewhat 
abruptly truncated behind. 
G-aster and legs of the usual 
conformation. 
Surface of body smooth and shining, apparently with small, sparse, 
piligerous punctures. 
Hairs sparse, erect, most noticeable on the clypeus, mandibles, 
palpi and tip of gaster. 
Color deep reddish brown. 
Described from a single well-preserved specimen (X 2) in the 
Klebs Coli. 
This species appears to be closely related to S. angustata, but 
I have described it as distinct, on account of its very small size, the 
larger and more anteriorly placed eyes and the shortness of joints 
2 — 5 of the funiculus. 
Among recent species which are closely related to S. angustata, 
simplex and lacrimarum may be mentioned the Indian S. nigra Roger, 
compressa Roger, allaborans Walker, difficilis Forel and binghami 
Forel, the Australian S. leviceps F. Smith and the Madagascarene 
S. rakotonis Forel and S. hysterica Forel.
