[March 
its anterior peduncle very slightly depressed, the nodal 
portion approximately circular in cross section. 
Body generally smooth and strongly shining ; under- 
side of head with strong, crowded but separate foveolae; 
a few small, inconspicuous foveolae on dorsum of head 
in zone bordering occipital excision, but most of upper 
surfaces of occipital lobes with no more than small, widely- 
spaced punctures. Pubescence and pilosity absent from 
body generally, except for the sensory setae of labrum 
and mandibles, the short hairs at gastric apex, and a 
dilute reclinate pubescence of the antennae, legs and 
mouthparts, most noticeable toward the extremities. 
Color rich medium brownish-red; vertex and a median 
area just behind clypeus almost imperceptibly shaded; 
mandibles, antennae, legs and gaster clear yellow; mandi- 
bular apices, dorsolateral margins of occipital lobes, pro- 
podeal spines and both nodes ferruginous yellow. 
The holotype [mcz] was collected with seven worker 
and two dealate female paratypes at the village Ebabaang, 
altitude about 1400 m., in the Mongi Watershed, Huon 
Peninsula, New Guinea, April 18, 1955 (E. 0. Wilson 
leg.). The seven worker paratypes [mcz, hnm, usnm] : 
TL 5. 9-6. 4, HL 1.31-1.43, HW 1.12-1.23 (Cl 85-87), ML 
0.74-0.82 (mi 57-58), wl 1.59-1.75 mm. Color of head 
and alitrunk varies from light to rather dark reddish- 
brown; infuscation of vertex absent to fairly distinct. 
Propodeal spines vary slightly in length, angles of eleva- 
tion and divergence, and in strength of their arch as 
seen from the side; in some specimens the tips are a little 
more strongly deflected ventrad than in others. 
One of the two dealate females: tl 6.5, hl 1.43, hw 
1.28 (ci 90), ml 0.80 (mi 56), wl 1.76 mm. Similar to 
worker, with the female differences usual for dacetines. 
Compound eyes only slightly larger than in worker; ocelli 
small but distinct. Meso- and metanota together forming 
an abruptly raised dome, smooth and shining, with scat- 
tered small punctures. Propodeal spines straight (not 
gently arched as in worker), only the extreme tips slightly 
deflected ventrad. Sculpture, color and pilosity as in 
worker, except that punctures on dorsal surfaces of oc-
