neis; abdomine nigro ; squama oblongo-ovata.

tarsisque fuscis; metathorace supra rotundato, postice truncato. 
Worker. Length 1$ line. Dull chestnut red; the head rounded be- 
hind the eyes, the latter ovate, and situated rather more inwards than 
is usual, the eyes are also rather large; the antenne, tibic, and tarsi 
fuscous; the antennz inserted rather wide apart, nearly in a line with 
the inner margins of the eyes. Thorax, sub-rugose above, narrowed 
posteriorly, and deeply constricted between the meso- and meta- 
thorax ; the latter elevated, rounded above, and truncate behind, the 
truncation obliquely concave. Abdomen ovate, produced anteriorly 
over the node of the peduncle, which is oblique, and falls into the 
truncation of the metathorax. 
Hab. Celebes (Tondano). 
This species belongs to Foerster’s genus Tapinoma.

1. Polyrhachis hastatus, Latr. Hist. Nat. Fourm. p. 129, pl. 4. fig. 23, ?. 
Hab. Celebes; India. 
The specimen from Celebes has the metathoracic spines shorter than 
Indian specimens which I have seen, and those on the node of the peduncle 
are also rather shorter ; however, in its opake blackness and in every other 
particular the insect is identical. 
* A figure of the scale of the peduncle of each of the new species described 
will be found on Plate I., illustrative of this paper.
