borders only slightly indented above the eyes and in having 
the eyes themselves much larger and more protruding, more 
nearly prospicient. 
Vertex evenly convex, feebly impressed in the middle; 
occipital lobes strongly depressed and nearly plane dorsally ; 
broadly expanded both posteriad and laterad. Clypeus more 
than half again as broad as long, moderately convex, an- 
terior border emarginate and weakly depressed in the 
middle. 
Mandibles about as shown in Emery’s wallacei figure, 
slightly depressed and very slightly broadened just at their 
insertions. Seen from the side, they tilt slightly dorsad and 
are feebly arched. Apical fork of two long spiniform teeth, 
subparallel and forming a U, the ventral tooth (L 0.10 mm.) 
about % as long as the dorsal (l 0.15-0.16 mm.) ; no inter- 
calary denticle. Preapical tooth slightly curved, spiniform, 
situated at approximately the apical third of the ml, its L 
ca. 0.10 mm. 
Antennal scapes (straightline L about 0.60 mm.) very 
feebly bent posteriorly near the base, where they are very 
slender; apical half gradually incrassate, thickest at about 
the apical quarter, and gently arched so as to follow the 
contour of the sides of the head when in repose. This adapt- 
ation evidently compensates for the incomplete condition of 
the scrobes, and is seen in somewhat similar form in szalayi. 
Funiculus L 0.65 mm., the apical segment occupying just 
half this length ; iv longer than i ; ii and iii subequal, longer 
than broad, together not quite as long as i. 
Anterior promesonotum gently convex, descending be- 
hind through the evenly concave posterior half of the meso- 
notum to the lower, extremely feebly convex (nearly 
straight in profile) propodeal dorsum; metanotal groove 
obsolete. Promesonotum seen from above with a very nar- 
rowly rounded and poorly developed anterior border ; cervix 
with a median dorsal carinula. No traces of humeral angles 
or tubercles, humeral region gently convex, promesonotal 
suture obsolete. Propodeal teeth long (l ca. 0.12 mm.), set 
far apart, slender, acute, feebly diverging and elevated at 
an angle of about 35° from the plane of the propodeal 
dorsum. Infradental carinulae indistinct, becoming obsolete 
ventrad.
