Queensland: Mt. Tambourine (E. Mjoberg). 



This form, too, I belie^■e, should be regarded as a distinct species, 

 as the differences which, according to Forel, separate it from clams 

 and ourryi are considerable. It is much larger (5.2-5.3 mm.) than 

 clarus, much stouter and of a much darker color, and the antennae 

 are very different, the scapes being longer and more gradually- thick- 

 ened towards their tips, funicular joints 2-6 are much more transverse 

 and the terminal joint is shorter. The thorax and petiole are more 

 convex than in cmcryi and the petiole is not concave in front nor 

 marginate abo^'e, the postpetiole is longer, the first gastric segment 

 much broader, the gastric constrictions are less pronounced, the 

 puncturation of the body is sparser, the pubescence more dilute and 

 the color paler, brownish red.
