petiolar node flat, meeting the slightly concave anterior 
slope at somewhat less than a right angle, the transverse 
summit formed by their juncture distinctly sinuate in the 
middle. Postpetiolar node oblong, nearly twice as broad 
as long. 
Reticulate rugosity of head and pronotum much coarser 
than in the worker, with abundant, deeper, circular f oveolse ; 
mesonotum and scutellum smoother, without reticulate 
rugules and with smaller and more scattered foveolse, espe- 
cially on the anterior and median portion of the mesono- 
tum. Scrobes, pleurae and epinotum regularly and sharply 
reticulate-rugulose, or rather coarsely, densely and evenly 
punctate (“thimble-punctured,” to use the French expres- 
sion) ; petiole and postpetiole less shining and more coarsely 
punctulate than in the worker. Gaster and legs under a 
high magnification very finely and superficially shagreened. 
Pilosity as in the worker but the long sparse hairs on 
the body are proportionally shorter and more flexuous and 
on the gaster more numerous. 
Head, thorax and pedicel darker and more ferruginous 
than in the worker; each ocellus with a round black spot 
at its inner orbit ; posterior border of scutellum and a pair 
of large elongate parapsidal spots dark brown. Membranes 
and veins of wings clear and colorless, pterostigma brown. 
Described from four workers and six females taken July 
20, 1915, by Mr. Henry Hacker near Brisbane, Queensland. 
Mayriella abstinens venustula subsp. nov. 
Worker. Length 1.3 mm. 
Very similar structurally to the typical abstinens even 
in the shape of the epinotal teeth, which though distinctly 
larger are nevertheless blunt and shorter than their basal 
diameter. Longitudinal costae in the mesoepinotal groove 
more distinct. Anterior slope of petiolar node slightly con- 
cave in profile and therefore more as in the subsp. hackeri. 
Head, thorax and pedicel less shining owing to the greater 
sharpness of all four components of the sculpture namely 
the basal microscopic reticulation or punctulation, the 
coarser, even thimble-puncturing of the scrobes, neck, 
pleurae, epinotum and ventral and lateral surfaces of the
