rally a little longer and broader than the 2nd, or subequal to it ; the 
following increasing towards the apex, subglobose. In a few cases the 
antennæ are apparently of 14 segments, the 3rd being more or less 
perfectly divided in two segments, of which the basilar one is small, 
and shorter than the 2nd antennal segment. Labrum subovate, nearly 
as broad as long, not reaching to one third of the mandibles, with a few 
hairs at the tip. Mandibles dark reddish-brown or bla¬ 
ckish, generally a little longer than half the head, 
incurved, with acute tips ; the inner margin with mi¬ 
nute serrations. Pronotum small, narrower than the head ; 
saddle-shaped, the anterior portion raised, bilobed, Me- 
sonotum not quite so broad as the pronotum, metano- 
tum broader. The hind legs a little exceed the apex of 
the abdomen. Abdomen elongate, pale, with rudimen¬ 
tary styli. 
Worker. 5 mm. long. Head rounded behind, yello¬ 
wish or brownish, with pale suture. Epistoma not very 
prominent. Antennæ short, of 13 segments, the 2nd 
subequal to the 3rd (very little longer or shorter ; and 
sometimes divided in two; the others increasing some¬ 
what towards the apex. The apical tooth of the mandibles not larger 
than the following. Pronotum narrower than the head, saddle-shaped, 
the anterior portion raised, lobed in the centre. The hind legs do not 
reach to the apex of the abdomen. Abdomen pale. Styli present, but very 
minute.

This species builds ovoid nests 30—40 cm. long, on trees at an 
height of about 3 m. from the ground. 
This species is evidently allied to T. distans Hav. of Borneo, and 
the Imagos seem to be very close one to the other, but the soldiers are 
notably different.

I give this name to a series of forms whose queens I am unable 
to distinguish from those of T. Bírói, but which certainly possess distinct 
soldiers. These are at once distinguishable from those of the typical 
form by their shorter and much less curved mandibles. The 
antennæ are of 13 segments, the 3rd generally more or less distinctly 
shorter than the 2nd.
