que, their surfaces, much roughened by numerous small im- 
pressions and ridges, cephalic rugae rougher than those of 
the thorax. Antennae with a few shining oval punctures. 
Head approximately as broad as long, broadest between the 
posterior fourth and fifth, the sides feebly convex, the oc- 
ciput broadly and evently concave. Epinotum with two 
divergent, serrate carinae consisting of three or four obtuse 
teeth at the junction of the basal and declivious faces. 
The collection contains numerous specimens from south- 
ern China and Burma and a few from Indochina. There is 
a very large amount of material from the Philippines, two 
workers and a female from northern Borneo and a number 
of specimens from Java. 
Ondontoponera transversa var. infuscata var. nov. 
This variety differs from the typical form in the color of 
the clypeus and the appendages. The mandibles, clypeus, 
antennae and legs are blackish brown. The rugae are in most 
cases more shining than in the true transversa. 
Infuscata appears to be confined to Java and some of 
the closely adjacent Sunda Islands. A large series of work- 
ers taken by L. G. E. Kalshoven in the teak forests of Sa- 
marang, Java, may be considered as type material. There 
are a few specimens taken by N. Gist Gee in Buitenzorg, 
Java, and others from Mao Marroe, East Soemba (Sunda 
Islands) collected by Dammerman.

(1925) worker. 
Biconcentrica was originally separated on the circular 
configuration of the rugae of the pronotum but, as has been 
already shown, the value of this character is lessened since 
it sometimes occurs in the typical transversa. There are, 
however, a number of other differences. The head of bicon-
