228 HYMENOPTERA. 



Halictus (Cliloralictus) humilis Smith. 



Two females from Adelaide {Schombzirgk) are in the Berlin 

 Museum. In one, the legs are practically all black, with red 

 knees ; in the other the tibiae and tarsi are ferruginous, and the 

 middle and hind femora largely reddish. In the latter the 

 stigma and nervures are pale ferruginous, in the former the 

 stigma is darker, though not very dark. Both spurs of the 

 hind tibiae are alike, finely ciliate. The type locality of 

 humilis was Champion Bay, which is certainly a long way from 

 Adelaide ; but so far as I can tell from Smith's description 

 and my notes on his type, the present insect is true humilis. 

 Richard Schomburgk lived at Adelaide ; he forwarded to 

 Europe plants collected by Schultz in Northern Australia, 

 and very likely the Schultz bees may also have passed 

 through his hands. There may be here a possible source of 

 confusion in labels. 



Halictus (Cliloralictus) dampieri Ckll. 



This was described from the female. I have before me 

 two males from Mackay, Queensland, Sept., 1891 {Turner 

 661). The male is a slender insect, with a long narrow dark 

 green abdomen ; antennae black, the long flagellum strongly 

 crenulated beneath ; lower margin of clypeus broadly dull 

 white; knees, and all the tibiae and tarsi ferruginous. De- 

 tails of sculpture, etc., as in the female. 



Female H. dampieri was taken at Mackay, at flowers of 

 Xanthorrhoea, April, 1899 ( Turner 706) . A blue-green variety 

 is from Mackay, at flowers of Eugenia, Nov., 1899. 



Halictus flindersi Ckil., var. a. 



Mackay, Queensland, March, 1892 and 1900 {Turner 440). 

 This species is remarkable for having a very well formed 

 ventral abdominal scopa of curled white hairs. In two of the 

 specimens before me this scopa contains pollen. The " var. 

 a," with green mesothorax and scutellum, seems to be the 

 more normal form. 



Halictus behri sp. nov.

 mesothorax and scutellum shining, brilliant purple-blue ; other parts of
