76 AUSTRALIAN BOMBYLIID^. AND CYRTID^ (UIPTERA), 



In the present paper new species are not described, but 

 an attempt is made to complete the synonymy of those already 

 known, and to collect together a complete catalogue of refer- 

 ences. The species have been well illustrated by various 

 authors, and therefore figures are not given with this 

 catalogue.
