1. Self-colored form: N.E. NEW SOUTH WALES between 
about S. lat. 29.40 and 30.20 (not including Sydney — see above) 
(open circles in Fig. 15). 
Specific records are: Point Lookout to Grafton , dealate female, 
April 1958, (P. F. Darlington). New England National Park , 
Platypus Creek (elevation not given, probably 2-3000 ft — see LeGay 
Brereton, 1963, fig. 1), in log, February 27, 1961 (Nicholls). The 
Dorrigo 3000 ft (W. Heron). 
2. Bicolored form: Extreme S.E. QUEENSLAND, between 
about S. lat. 27.20 and 28.20 (closed circles in Fig. 15). 
Specific records are: Mt. D’ Aguilar Range , 2000 ft, nest in 
rotting log, May 4, 1962 (RWT acc. 799). Cunningham's Gap , 
2500 ft, nest in rotting log, May 1, 1962 (RWT). Stradhroke 
Island, dealate queen, December 3, 1912 (H. Hacker). Tamborine 
Mountain: no further data (A. M. Lea) ; Cedar Creek, ex rotting 
logs — dealate female, May 15, 1951, workers November 13, 1950 
and May 12, 1951 (W. L. Brown) ; worker under log, February 27, 
1956 (B. B. Lowery). Binna Burra: c. 2600 ft: nests in rotting 
logs, one with alate female, May 22-23, 1962 (RWT accs. 1145, 
1182); several series of workers collected straying at night (see 
below under “ecology”) , May 21-23, 1962 (RWT). Lamington 
National Park, Coomera Gorge: leafmold berlesate, October 29, 
1955 (T. E. Woodward) ; 2200 ft, nest in rotting log, May 23, 1962 
(RWT acc. 1168). 
All the above records are specifically cited as rain forest collections, 
except the dealate female from Stradbroke Island, which has no 
ecological data. 
IV orker variation. Measurements and indices of workers from the 
above series are summarized in Table 1. The similarity of ranges and 
means in the two color variants is obvious and reflects their consider- 
able resemblance in all characters except color. 
The coloration of the types (Plate 3, lower figure) is typical of the 
self-colored form. The bicolored form has the mesosoma, petiole and 
postpetiole very dark blackish-brown, contrasting sharply with the 
golden-brown head, gaster and appendage's (Plate 3, middle figure), 
and the antennal infuscation is much less intense. The pronotum and 
postpetiole may be medium to dark reddish-brown, usually in the 
larger specimens of a given series. Such individuals are probably 
incompletely colored ; since these areas are the last to become fully 
pigmented in callow specimens. 
The mesosomal spines vary in thickness, length and inclination. The 
pronotal pair are typically longer and thicker than the propodeal ones,
