scutellum polished ; area of metathorax dull, subreticulate, with coarse rugae, 
110 shining margin ; tegulae rufous ; wings hyaline, the pale stigma dark- 
margined ; second cubital cell very broad ; first recurrent nervure joining third 
cubital cell, some distance from base ; legs with white hair, knees red, and 
tarsi pale red ; abdomen shining, a strong sulcus between first and second 
tergites ; hind margins of tergites somewhat pallid ; no hair bands or spots. 
Brisbane, Nov. 19, 1913 (H. Hacker). Runs hear II. idoneus Ckll. , but 
that is much larger. It is much like II. cyclognathus Ckll., but the face is 
much narrower, &c. The general aspect suggests H. forticornis Ckll., but the 
antennae are quite different. The venation is peculiar. 
Halictus euryurus sp. n. 
Male. Length nearly (5 mm., anterior wing about 5 ; black, the abdomen 
broad-oval, the hind margins of the tergites beyond the first stramineous ; face 
broad, tegument of clypeus entirely black, mandibles obscurely reddish apically ; 
hair of head and thorax rather abundant, long, white, long but thin on front 
of head ; antennae of moderate length, black, the flagellum very obscurely 
brownish beneath : clypeus flattened, shining, depressed in the middle at lower 
end ; supraclypeal area very sparsely punctured ; front densely punctured ; 
mesothorax and scutellum strongly punctured, only moderately shining ; area 
of metathorax with sharp straight plica', only two or three in middle wrinkled, 
margin shining ; posterior truncation dull ; tegulae dark rufous ; wings clear 
hyaline, iridescent, stigma pale reddish, nervures pale, second cubital cell 
broadened below, receiving first recurrent nervure some distance from its end; 
outer recurrent and intercubitus much weakened ; legs black, small joints of 
tarsi rufescent, hind tibiae robust ; abdomen moderately shining, finely punctured. 
Adaminaby, N.S-W., Oct. 19, 1918 (A. J. Turner)-, Queensland Museum. 
Somewhat allied to II . macrops Ckll. and II. bursarice Ckll. The metathorax and 
antennae separate it at once from II. macrops. The mesothorax is much more 
coarsely punctured than in II. clariventris Friese. 
Halictus sculp turatus sp. n. 
Male. Length about 6-5 mm. ; black, moderately robust, the abdomen 
without hair bands or patches ; face rather broad, with thin white hair ; 
clypeus with a transverse cream-coloured band : labrum reddish ; mandibles 
reddened subapieally ; antennae rather long, flagellum moniliform, obscurely 
brownish beneath ; front very densely punctured ; hair of thorax scanty, white ; 
long, erect, and pure white on postscutellum ; mesothorax shining, strongly 
punctured, median groove strong, and on each side of it anteriorly oblique 
striae ; area of metathorax semilunar, not pointed behind, appearing to have no 
shining rim. but seen from behind a small shining edge is visible ; surface of 
area strongly sculptured all over, the plicae wrinkled and irregular in middle, 
straight and distinct at sides ; tegulae dark rufous ; wings brownish hyaline, 
iridescent, stigma dark reddish brown ; nervures fuscous, second cubital cell
