thorax more or less distinctly plicatulate. This is not H. 
urbanus var. stradbrokensis Ckll., which is larger, with 
dark tegulse, and area of metathorax regulose, not plicate. 
H. urbanus is a puzzling species, running into a number 
of local races, and H. murrayi is certainly very closely 
allied. 
Queensland; 10 $ from Babinda, April 8-16, 1919 (Wil- 
liams) ; and one from Halifax, June 17 (Williams ) . H. 
murrayi was described from the Northern Territory: it 
now appears more widely distributed and variable than 
was supposed. 
Halictus subcarus n. sp. 
2 . Length about 5 mm., anterior wing about 3.5 ; head 
rather broad, dark green with fine white pubescence on 
face and front ; mandibles red except at base ; clypeus shin- 
ing, the apical half black, with a few very large punctures ; 
supraclypeal area and front dull; flagellum bright fer- 
ruginous beneath; mesothorax and scutellum bright Prus- 
sian green, the former dull, the latter more shining, but 
not polished; metathorax dark green, the basal area with 
short but strong plicae, the margin of the area thickened, 
obtuse, blackish; pleura dark green; tegulse clear fulvous; 
wings hyaline, stigma dark reddish, nervures pale reddish, 
outer recurrent and intercubitus colorless and almost obso- 
lete; second cubital cell higher than broad; femora black, 
with knees red; tibise and tarsi bright ferruginous; hind 
spur with two large long spines ; abdomen olive green, with 
fine pale pubescence, hind margins of tergites reddened; 
venter with much white hair. Under the microscope, the 
mesothorax is seen to be minutely tessellate and finely 
punctured, and the front below the ocelli is longitudinally 
striate. The face is conspicuously narrower than in H. 
williamsi, and the clypeus is more produced. It is easily 
known from H. floralis Sm. by the dull scutellum.
