538 Mr. T. D. A. Cockerell — Descriptions and 



abdominal bands a lively yellowish fulvous. Structurally it 

 agrees \rith cetera. 



Megachile relicta, sp. n. 



$ . — Length 10 ram. 



Parallel-sided, black, witli white pubescence, giving the 

 "whole insect a hoary appearance. Head ordinary ; eyes 

 brown ; face rather broad, with much Avhite hair ; flagellura 

 bright ferruginous beneath; vertex well punctured; clypeus 

 transversely swollen or obtusely ridged, coarsely punctate 

 above, below, where it slopes inward, shining and scarcely 

 punctured, the lower margin with two large, widely separated, 

 triangular teeth ; mandibles broad, not greatly elongated, 

 slightly reddish near apex, with a narrow band of yellowish 

 hair parallel with the cutting-edge ; labrum long, with a pair 

 of subajjical teeth ; thorax above densely rugoso-punctate ; 

 tegulae reddish, stained with piceous. Wings clear. Legs 

 black, the tarsi red at apex, inner side of tarsi with pale 

 fulvous hair ; hind tarsi not broad. Abdomen punctured, 

 with greyish-white hair all over, giving it a dusty appear- 

 ance ; faint linear bands can be seen on the hind margins of 

 the first three segments, but the abdomen can hardly be 

 called banded ; a dense patch of white hair on each side of 

 first segment ; ventral scopa entirely white. 



Hah. Tennants Creek, S. Australia {Field; Nat. Mus. 

 Victoria, 37). 



A peculiar species, without near relatives. By the 

 pruinose abdomen it resembles M. fidvomanjinata, Ckll. ; 

 by the clypeal structure it resembles M. clypeata, Smith. 



Megachile vestitor, Cockerell. 



A male from W. Australia {Duhoiday ; Nat. Mus. Victoria, 

 11) is only about 9^ mm. long, breaking down the distinc- 

 tion of size between vestitor and Smith's fabricator. I now 

 think that the two are probably identical, but, if so, Smith's 

 account of the anterior tarsi is ambiguous and insufficient. 



Megachile remeata, sp, n. 



5 . — Length a little over 12 mm. 



Parallel-sided; wings dilute brownish, the apical half of 

 the anterior wings more strongly so ; ventral scopa white, 

 Avith a few hardly noticeable dark hairs at extreme apex ; 

 first, abdominal segment covered above and at sides with 

 long white hair; second and third with dense white apical
