16 ON A SMALL COLLECTION OF HYMENOPTERA FROM NARRABRI. 



Melaleuca leucadendron growing on the banks of the Fitzroy 

 River, near Derby, N. W. Australia. Previous to this, Smith 

 (Trans. Ent. Soc. London, 1868, p. 233) had described a very 

 different species from South Australia under the same specific 

 name. Both specimens are in the British Museum, so that it is 

 hard to understand why the error has not been rectified before. 



I should propose that the northern species, which evidently has 

 no right to the specific name cons2ncuus, should be re-named 

 Smithii. 



17. Xylocopa muscaria, Smith. 



Four specimens (£) of the common carpenter-bee, which con- 

 structs nests in the flower stalks of the grass-trees {Xantlior- 

 rhcea) ; found all over New South Wales. 



18. Xylocopa ^estuans, Latr. 



Four specimens of this larger species, which ranges into North 

 Queensland. 



19. Crocisa nitidula, Fabr. 



This handsome spotted bee has a wide lange, from South 

 Australia to North Queensland. 



20. Anthopora pulchra. 



Three specimens of this fine blue-banded bee, which is found 

 over the greater part of Australia. 



21-23. Megachile spp. 



Five specimens of leaf-cutting bees, referable to three species, 

 all of which are also to be found about Sydney.
