NEW AUSTRALIAN BEES.

Paracolletes providus (Smith). 
Females : Stanthorpe, Q., 7-10-24 and 3-10-24 (F. A. Perkins). I have 
received additional specimens of P. hackeri CkH, from Mr. Hacker, and find 
the distinction from P. providus difficult lo appreciate. Typically, the abdomen 
of P. providus is more polished and oily -appearing, not so strongly punctured, 
while P. hackeri has a tuft of dull fulvous-tinted hair in front of each tegula. 
But I am no longer confident that these differences do not fall within the 
range of variation of P. providus. The matter can only be settled by those 
on the spot, or by the collection of good series in typical localities* 
Nomia geophila sp. n. 
Male. Length 8-9 mm., anterior wing 6-5 ; black, with the hind margins 
of the second and follow'ing abdominal tergites hyaline ; pubescence white, 
dense on face, covering the surface ; on the thorax above the hair is greyish : 
tegument of clypeus wholly black ; mandibles more or less rufous beyond the 
base ; flagellum very short for a male, entirely dark ; mesothorax shining, 
with distinct not very close punctures ; scutcllum quite closely punctured, 
depressed in middle ; metathorax shining, the striated basal area forming a 
very narrow' band, obtusely angulatc behind in middle ; a depressed polished 
space above hind legs ; teg ulie very dark brown, with hyaline margins ; wings 
hyaline, the apical margin faintly clouded ; stigma small, dusky rufous ; nervines 
dark fuscous ; second cubital cell very small, receiving recurrent nervure beyond 
the middle ; legs dark brown, with dull white hair ; hind legs not modified, 
but all the femora very short and small ; abdomen finely punctured, very 
conspicuously on first tergite, no hair-bands ; hind trochanters with a small 
apical process above ; venter not modified ; claspers long and thin, with an 
expanded apex, from the inner corner of which, directed obliquely mesad, is a 
finger-like process ; spatha broad basally, narrowing to the apical part, which 
is rod-like, obtuse at end ; tongue slender, dagger-like, only moderately long. 
Two males: “Bred earth cells, 10-11-18, Moree ” ; Queensland Museum. 
Closely related to N. gilberti Ckll., but antennae a little shorter, mesothorax 
shining, and postscutellum without the dense covering of pure white hair, nor 
are there conspicuous white hair-patches at sides of scutellum. In N. frenchi 
Ckll. the antennae are very much longer. 
Nomia grisella Ckll., described from Cape York, has been found by W. C. 
Dormer at Gordonvale, Feb. 24, 1923. 
Exoneura tasmanica sp. n. 
Male. Length 7 mm. ; head and thorax shining black ; hair of head 
black, thin but long and outstanding on face, on thorax pure white beneath, 
and dorsally brown, a sort of very dilute chocolate colour ; eyes black, very 
large, converging below; clypeus long and narrow, cream-coloured, with dull 
surface ; in the narrow space between clypeus and eye there is on each side a 
cream-coloured line ; labrum w hite, with a black spot at each side, mandibles
