650 m, leg. S. Peck, B-278. irian jaya: near Phillips Petroleum Base 
Camp, SE Salawati 1. (just off western extremity of Vogelkop), 
swamp forest near sea level, leg. Brown No. 81-189, nest in rotten 
wood, with at least 15 workers, a dealate queen, a male, about a 
dozen pupae in tan cocoons, and a few half-grown larvae. Austra- 
lia, N. QUEENSLAND: Black Mt. road N. of Kuranda, 300-600 m, leg. 
P.F. Darlington, in rain forest, small colony with at least two deal- 
ate queens. Mt. Cudmore Range, 1 1 mi. N. of Ingham, about 210 m, 
six workers from rotten log in small roadside patch of disturbed rain 
forest, leg. Taylor, Acc. No. 1706. Mulgrave Forestry Road, 
17° 18'S, 145°48'E, leg. Ward No. 4366, from rotting epiphyte fern 
on rain forest floor. 
From the Solomon islands we have three scanty samples of 
forms sent from anic that could belong to M. tenuis, or to sibling 
species: 
(1) A large form, extending some of the tendencies seen in Aus- 
tralian series; HW 0.80, EL 0.09 mm; scapes reaching posterior 
border of head. Propodeal dorsal profile a little more convex than 
usual in M. tenuis. Color castaneous. Two workers from Guadal- 
canal I.: Mt. Austen, Feb. 1966, leg. P.M. Greenslade, No. 21095. 
(2) A small worker, also from Mt. Austen, Guadalcanal, 
14/5/ 1963, leg. P.M. Greenslade, No. 6076; HW 0.55, EL 0.03 mm; 
scapes very short, failing to reach posterior border of head by at 
least the apical scape width; posterior border of head weakly con- 
cave. Color yellowish brown. Sides of head straighter and more 
parallel-sided than in the other Mt. Austen sample. 
(3) A worker from San Cristoval L, Humi R. est., N.E. Wainoni, 
leg. Royal Society Expedition, 1966-1, HW 0.60, EL 0.05 mm; sides 
of head almost perfectly straight and parallel, posterior border fee- 
bly convex; scape fails to reach posterior border of head by about 
half of apical scape width; mandibles unusually short (ML 0.37, 
MLO 0.47 mm) and broad; basal angle forming a distinct convexity. 
Color deep brownish red. 
I suspect that the Solomons will eventually yield much more vari- 
ation in the tenuis complex; the available material is simply inade- 
quate as a basis for understanding the complex in this archipelago.
