hair-bands, broadly interrupted in the middle, the other 

 segments without any pale bands or spots ; eyes convcri^ing 

 above ; clypeiis low and very broad, subearinatc in middle, 

 witli a tooth on middle of lower margin ; mandibles very 

 long, parallel-sided, bidcutate at end, the inner margin with 

 orange hairs ; anttn-ior tibirc in front with a long (laneeolate), 

 smooth, shining, hairless area, tlie inner side of these til)ife 

 densely covered with silver-white hair; flagellum obscurely 

 marked with red beneath ; mesothorax closely and minutely 

 l)nnetnred, but shining between the punctures. 



Hab. W. Australia {Duhonlnij ; Nat. Mns. Victoria, 5). 



Closely resembles M. semiluctnosa, but differs in the bi- 

 dcutate mandibles, the slightly instead of strongly arched 

 margin of clypeus, the much more finely and minutely punc- 

 tured mesothorax, and the shining finely punctured abdomen. 



Megachile revicta, sp. n. 



? . — Length 15 mm. 



Parallel-sided ; wings with the apical half brown, the 

 basal hyaline, in the manner of M. fabricator, but the third 

 abdominal segment without hair-bauds or spots, and the 

 man(lil)Ies are diflferent. This is another species superficially 

 like M.semiluctuusa, from which it differs thus : — Head seen 

 from in front round, the vertex rounded (not flattened), its 

 scattered black hairs .short, very minute ; antennae, in one 

 plane, broadly rounded (not expanded) and obtuse at tip ; 

 vertex shining, with large, partly confluent puuctures ; hair 

 of middle of face yellowish, of sides of face creamy white, of 

 clypeus very pale yellowish mixed with dark brown ; clypeus 

 low and very broad, coarsely rugoso-punctate, the lower edge 

 practically straight, with a median nodule; mandibles 

 extremely broad and massive, quadridentate, but the inner- 

 most tooth feeble, a line of ochreous hair running parallel 

 with the cutting-edge ; labial palpi shorter; mesothorax 

 densely and coarsely rugoso-punctate, almost like a Li- 

 thurgus ; ventral scopa wholly creamy white ; white band at 

 apex of second abnoniinal segment only about half as broad, 

 very clear white, as also the hair covering first segment; no 

 lateral spots of hair on third segment ; abdomen shining, 

 with very large irregularly placed punctures ; tegulaj shining 

 black, with a curious fringe of pale hairs curling over the 

 base and ends, covering more than half the surface ; hair on 

 inner side of hind tarsi dark fuscous, on tlie others more 

 reddish.
