NEW AUSTRALIAN BEES, IN THE COLLECTION OF 

 THE BRITISH MUSEUM. 



By T. D. a. Cockerell. 



Paracollefes roseoviridis, n. sp. 

 (^ . Length about 8 mm. ; in all respects very close to P. carina- 

 tulus, Ckll. (from Queensland), but differing thus : more robust, with 

 a broader abdomen; head, thorax, and abdomen yellowish green 

 instead of blue green, the abdomen with the hind margins of the first 

 two segments, and all the segments beyond, suffused with a rosy tint, 

 which covers the fourth and fifth segments with a rich glow, and shows 

 a little purple ; stigma more brightly coloured ; second submarginal 

 cell less narrowed above ; second recurrent nervure joining third sub- 

 marginal cell a little distance from its end (at its end in carinatidus) ; 

 area of metathorax not only transversely carinate, but also with con- 

 spicuous transverse grooves or deep strife, especially just below the 

 keel ; hind tibife and anterior tibifB in front, ferruginous, but the 

 middle tibife, and anterior tibiae behind, dark ; hind femora ferruginous, 

 with the basal half strongly suffused with black. Other characters 

 are : hair of face and thorax above light fulvous or orange-tinted, but 

 that of vertex long and grey-black; flagellum brownish beneath, the 

 last joint a little rufescent; b. n. meeting t. m. ; first r. n. joining 

 second s. m. at its middle ; wings clear ; tarsi ferruginous ; lateral 

 pieces of genitalia shaped rather like the end of a finger seen in out- 

 line, fuscous basally and subhyaline apically ; median piece with its 

 rounded apical part dark reddish centrally, and hyaline at the mar- 

 gins ; nearly the lower half of clypeus black, but the rest green. 



Hah. W. Australia, 68. 6. The numbers cited are the 

 accession numbers of the Museum. 



Halictus dampie7'i, n. sp. 

 5 . Length about 6 mm. ; head and thorax dark olive-green, the 

 front and mesothorax dullish, with a satiny lustre ; apical part of 

 mandibles reddish ; antennne entirely dark ; clypeus shining black, 

 with a few punctures, except its upper margin, which is broadly green ; 

 tegulfe rufous, blackened basally ; area of metathorax large but not 

 well defined, coarsely granular, with an inconspicuous and minute sub- 

 reticulate sculpture ; wings quite clear, brilliantly iridescent, stigma 

 and nervures dark fuscous ; b. n. falling some distance short of t. m. ; 

 first r. u. meeting second t. c. ; third t. c. and second r. n. very weak ; 

 legs black, with white hair, yellowish on under side of tarsi ; claw- 

 joints ferruginous ; hind spur with short stout spines ; abdomen dark 

 green, practically hairless, except at the apex, though there is a fringe 

 of hair along the lateral margins, at the dorso-ventral suture. With 

 the compound microscope, the front and mesothorax are seen to be 

 very minutely tessellate all over, with very few scattered shallow 

 punctures ; tlie area of metathorax is evidently reticulate in the 

 middle, the reticulations weakening and giving way to spots and dotted 

 Btriffi laterally ; the surface of the abdomen is impunctate, and covered
