than the volsellae which are curved, slender with knob-like 
apices and several long hairs. Stipites short, broad, and 
blunt, less than one-half as long as the sagittae. 
Hairs abundant, longer on mouth parts, front, dorsa of 
the thorax, node, and abdomen; longest on the sixth ab- 
dominal segment ; shorter on the antennae ; sparser and much 
shorter ventrally. Eyes with many, very short hairs. 
Wings conspicuously hairy; the surface hairs short; those 
fringing the margin twice as long. Genitalia naked, except 
the volsellae. 
Color ferrugino-testaceous ; legs, genitalia, and mouth- 
parts lighter. 
Integument smooth. 
Described from a single male from Buitenzorg, Java.

In his “Social Life Among the Insects” 2 (p. 335) Dr. 
W. M. Wheeler has suggested that the Tribe Leptanillini 
would have to be removed from the Dorylinae and raised 
to the rank of a subfamily. The senior author 3 , in his study 
of the larva of Leptanilla revelierei sardoa Emery, has 
supported this view. 
The Leptanillinae resemble the Dorylinae in the following 
characteristics. The frontal carinae are close together 
and do not cover the antennal insertions; the petiole con- 
sists of two segments in the worker, one in the male and 
female. A sting is present. The female is wingless; the 
thoracic sutures are more or less vestigial. In the male the 
subgenital lamina is usually bifurcate; cerci are absent. 
The tibiae have spurs, which are sometimes rudimentary. 
The larva resembles the known doryline larvae in the shape 
of the body, which is elongate, slender, subcylindrical, 
orthocephalic, and nearly straight, and in the small feebly 
chitinized mandibles. 
In contrast, the following characters of the Leptanillinae 
differentiate them from the Dorylinae. The workers are 
monomorphic and minute; the maxillary palpi are one- 
jointed ; the antennae are always 12-segmented. The lobed 
hypopygium of the female extends beyond the pygidium.
