Becords of Bees. 399 



Prosopis alcyonea, Erichs. 



Albany, W. Australia (/. J. W alker , 4:2m) , 1 S ; Franklin, 

 Ti.sraania (/. /. Walker, 3469), 1 ? . 



The difference in venation indicated by the above table is 

 not specific, I believe, the insects being so similar in all 

 other respects. The male has the first r. n. nearer the base 

 of the second s.m. on one side than on the other. Erichson 

 described only the female; the male has most of the face 

 bright chrome-yellow, but there is a black band down each 

 side of the ch^peus. The lateral face-marks narrow abruptly 

 just above the antennpe and are then continued very narrowly 

 nearly to the top of the eyes. There is a yellow mark in 

 front of the anterior ocellus. The curious shining tubercle 

 at the base of the metathorax is as in the female. Evidently 

 P. vidua, Smith, is the male of alcyonea, as Smith himself 

 surmised; Smith's type had the venation as in my female. 



Prosopis varicolor, Smith. 



Towusville, Queensland, 5. 3. 02 {F. P. Dodd) ; also 

 13. 12. 01 (same collector). Both sexes. 



This is evidently Smith's species, but the face-markings 

 are cream-colour rather than white and the punctures of the 

 abdomen are quite strong. The male, not hitherto described, 

 is like the female, but the face-marks are ivory-white, the 

 lateral marks larger and longer, and the much narrower and 

 more elongate clypeus has a large white triangle, occupying 

 the greater part of its disk. The blue and green shades of 

 the abdomen are very brilliant. 



Prosopis albonitens, sp. n. 



^ . — Length a little over 5 mm. 



Very closely and minutely punctured ; dark deep blue ; 

 light markings ivory-white, with a canary-yellow suffusion on 

 anterior and middle tibiae. Face below antennse all shining 

 ivory-white, the white ending between the antennae in a 

 rounded prominence, but along the orbital margins extending 

 upwards, gradually narrowing to a point, the distance from 

 which to the top of the eye is about as great as the distance 

 of the latter from a lateral ocellus ; mandibles and scape in 

 front ivory-white ; flagellum brown, pale and yellowish 

 beneath ; mesothorax convex, very closely and minutely 

 punctured; hind border of prothorax continued to cover 

 tubercles, but interrupted in middle, white ; base of meta- 

 thorax with a very large area, semilunar in form, with the
