NEW AUSTRALIAN ANTS. 
extending beyond occipital border by almost one-fourth their length ; first 
segment of funiculus twice as long as second, third shortest, fourth to ninth 
almost twice as long as broad, apical longer than the two preceding together. 
Eyes large, circular, placed just behind middle of sides. Ocelli prominent. 
Thorax one-fifth longer than broad. Pronotum three times broader than 
long, sides and front strongly convex. Mesonotum one-third broader than 
long, much broader in front than behind, a slight excision on posterior border, 
a deep and wide depression between mesonotum and epinotum, spiracles placed 
on top at each side. Epinotum almost twice as broad as long, broader behind 
than in front, a short blunt tubercle at posterior angles. In profile pronotum 
strong convex. Mesonotum feebly convex, sutures well impressed. Epinotum 
dropping behind, declivity at an oblique angle, longer than dorsum, with a 
strong tubercle at superior angle. Node thin, scale-like hidden in a recess at 
front of gaster. The gaster very large, almost four times as long as thorax 
and fully one and one-third times longer than broad. Legs short and robust. 
Habitat . — South Australia: Port Lincoln (F. E. Wilson, Oct. 1928.) 
Three specimens taken in a nest of Crematogaster laeviccps 
Smith. This is not near any of the previously described 
Australian species. The voluminous gaster at once distin- 
guishes it from all others. 
It is with some doubt that this form is described as a worker, 
the large eyes and ocelli suggesting a female. The thorax 
however has no trace of wing sclerites, and is that of a worker.
