[Mar. 
the node described ; the median ventral keel is moderately 
prominent and bears a blunt process anteriorly. The 
gaster long, its second segment vanlted in the manner of 
most proceratiine ants and the undercurved apical seg- 
ments directed anteriorly. 
The integument in general clearly shining through the 
dense pilosity, very sparsely and finely punctulate. The 
impressed spaces on each side of the median facial ridge 
coarsely and closely punctate, scarcely shining. Clypeus, 
carinal fusion process and antennae finely reticulate- 
punctate, subopaque to opaque. 
The entire body clothed densely with short suberect to 
erect whitish hairs, which are slightly shorter on the head 
and antennae, slightly more sparse on the legs. 
Head ferrugineous yellow, the gaster, mandibles and 
antennae somewhat lighter; thorax rich mahogany red, 
the petiole lighter ; legs and tip of gaster medium yellow. 
Holotype: One worker deposited in the Museum of Com- 
parative Zoology, No. 27788. Labelled “7 mi. S.E. La 
Foa, New Caledonia, Rocky Humus. March 11, 1945 (C. 
L. Remington ).” 
The nearest species of the genus in size is D. antarctica 
Emery (2), which measures 2 mm., but antarctica is yel- 
low throughout and has a differently shaped petiole. D. 
globus Forel and D. clavicornis Emery are much smaller 
and are described as having opaque integument; globus 
is red-brown throughout and clavicornis “flava”; both 
have differently shaped petioles. Mann (3) described 
specimens of clavicornis from the Solomons as “rich 
brownish red.” Since Emery’s type is a unique and 
possibly teneral, it would be best to wait for further col- 
lecting before formally differentiating Mann’s specimens 
as a color race. Forel ’s var. sauteri of globus from 
Formosa should be accorded at least subspecific rank on 
the basis of the description (4).
