WHEELER — ANTS FROM BORNEO AND LUZON 13 
middle and on each side. Frontal area indistinct; frontal carine long, 
diverging behind and bordering distinct antennal scrobes. These and the 
carine, though as long as the antennal scapes, do not reach the posterior 
corners of the head. Antenne 12-jointed; scapes reaching a little behind 
the eyes; funiculi with a very distinct 3-jointed club, the first joint of which 
is longer than the second, the first and second together equal to the termi- 
nal joint; the first and eighth joints of the remainder of the funiculus as 
long as broad, the intermediate joints distinctly transverse. Thorax 
narrower than the head, broadest through the pronotum, which has acute 
humeral angles and is feebly and evenly convex above. In front it rises 
abruptly from the neck, and is sharply marginate anteriorly and down 
each side to the insertions of the fore coxe. There is a very distinct meso- 
epinotal constriction, and the 
epinotum is small and unarmed, 
rounded in profile, without dis- eet 
tinct base and declivity and with- A 
out lamellate metasternal angles. 
Petiole cylindrical, seen from 
above nearly twice as long as 
broad, with straight parallel sides, 
in profile without a node, slightly 
convex above, its ventral surface 
in front with a stout tooth. Post- Figure 2.— Dilobocondyla borneensis sp. 
petiole about one and one third nov. Head and pronotum of worker in 
times as long as broad, slightly profile. 
broader than the petiole, broader 
behind than in front, with a distinct node above, highest posteriorly. 
Gaster nearly circular, flattened dorso-ventrally, formed almost entirely of 
the first segment. Femora and tibie strongly incrassated. 
Somewhat shining; mandibles very coarsely and densely rugose; head 
between the frontal carinze with ten coarse, equidistant, longitudinal ruge, 
the spaces between which on the front are opaque and densely punctate, 
behind traversed by cross-ruge. Posterior corners, sides and ventral 
surface of head very coarsely reticulate-rugose, with shining spaces between 
the rugee. Antennal scrobes in front with three transverse ruge, behind 
densely punctate. Thorax, petiole and postpetiole very coarsely reticu- 
late-rugose, like the back of the head; mesopleure and sides of the epi- 
notum coarsely longitudinally rugose. Gaster and fore coxe subopaque, 
densely punctate, the former also with short radiating ruge at the extreme 
base. Legs shining, the femora with small, scattered, piligerous punctures, 
the tibiz very finely longitudinally striated. 
Whole body covered with erect, delicate but blunt, whitish hairs; pu- 
bescence absent. 
Brownish black; mandibles, except their teeth, antennal scapes, base of 
funiculi, trochanters and terminal tarsal joints, reddish brown.
