Table 1. Pristomyrmex quadridentatus Andre. Comparison of standard 
measurements (in mm) and indices, yielded by specimens from all known 
series. Mean values italicized. The types are ostensibly from Sydney ( hut 
see text). Numbers in the “series” column refer to the following localities: 
1. New England National Park; 2. The Dorrigo ; 3. Mt. D’Aguilar; 4. 
Tamborine Mt. ; 5. Binna Burra. 
which are usually about sub-equal to the metapleurals. The bicolored 
form tends to have thicker pronotal and smaller propodeal spines than 
the self-colored form; but the overall variation is such that the avail- 
able quadridentatus material cannot be divided into two sets, co- 
extensive with the color-variants, on the basis of spinational characters.
