Halictus erythrarus viir. atrocyaneus n.v. Brisbane, Feb. 8, 1010. (199.) 



$. ^'e^y small, about 4 nu». long ; mesothorax very dark blue. Very distinct 

 in a])pearance, but I believe only a variety. The_ thorax, excepting the mesothorax, 

 is black ; abdomen chestnut rod, the first .segment black except apically ; mandibles 

 red; clypeus shining, with scattered large punctures; flagellum dark red beneath; 

 mesothorax dullish, extremely finely punctured ; area of metathorax rugose, wi1h a 

 broad shining rim ; tegulne dark reddish ; wings hyaline, stigma testaceous, nervures 

 pallid : legs bhuk, anterior tibia' obscurely reddish in front ; abdomen shining. 



Halictus clarigaster n.sp. Caloundra, Jan. 20, 1916. (197.) 



$. Length about 6' 5 mm. ; head and thorax black, abdomen clear bright 

 ferruginous, slightly dusky apically ; labrum and mandibles dark red ; head broad, 

 clypevLs shining and sparsely punctured ; front dull, except at extreme sides ; supracly- 

 j)eal area convex, prominent ; flagellum clear ferruginous beneath, except first joint 

 and extreme apex ; hair of head and thorax dull white ; mesothorax dullish, very 

 finely and closely punctured ; area of metathorax semilunar, glistening, with fine 

 mainly longitudinal rugse ; tegulae light ferruginous ; wings moderately dusky; stigma 

 and nervures dusky reddish, outer r.n. and t.c. weakened ; legs black wth all the 

 knees, anterior tibiae in front, and the other tibisB on inner side, ferruginous ; hind spur 

 with a few strong spines ; abdomen wthout bands or patches of hair, but delicately 

 white -pruinose from fine hair. Quite distinct from the similar H . ewarti Ckll. 



Halictus eboracensis n.sp. Ebor, N.S.W., Dec. 30, 1915. (A. J. Turner.) (201.) 



$. Length about 10 mm. ; black, the bases of abdominal segments 3 and 4 with 

 very broad bands of jiale greyish tomentum, and the base of second segment with a 

 cuneiform patch of the same on each side ; hind spur with a stout tooth toward base. 

 Closely allied to H. seductus Ckll., for which it would be taken on casual examination, 

 but the mesothorax is not dull anteriorly, and the plications at base of metathorax 

 are not so fine. The metathoracio plications resemble those of H . circumdatus Ckll., 

 but otherwise the sjiecies is cpiite distinct. 



Halictus speculellus n.sp. Brisbane, Feb. 15, 1916. (193.) 



$. Length about 5 mm. ; black, with the labrum and mandibles (except base) 

 dull rod ; flagollum ferruginous beneath ; tegulse clear rufo-testaceous ; tarsi rather 

 obscure ferruginous ; wings dusky, stigma dark reddish brown ; clypeus shining, 

 sparsely punctured ; front dull, except at sides ; area of metathorax with very fine 

 plicae, the broad rim dullish ; abdomen broad, thinly hairy, hind margins of segments 

 brownish. Mesothorax poUshed, the disc wthout punctures, except a few along the 

 middle line. Very like H. repertulus Ckll. (male), but not its female, as reperlulus has 

 a distinctly punctured mesothorax. Also allied to H. Sturti Ckll.. but smaller, with 

 more dusky wings, and different metathorax. 



Halictus brisbanensis n. sp. Brisbane, Sept. 17, 1914. (195.) 



$. Length 5 mm. or a little over ; head and thorax black, with the mesothorax 

 dull blue-green ; abdomen shining chestnut red, the hind margins of first three segments
