Synonymy. — The name Asilus nigritarsis was used by Wiedemann in 182] 

 for Basypngon (now Mallophora) nigritarsis Fabrieius from America. The 

 sjTionymy is given on the authority of Rehiner and Miss Ricardo. 



Description. — The shape of the male genitalia is more or less globular and 

 similar to but laiger than that of A. murinus Maequart, under which species fur- 

 ther particulars will be found. 



Hah. — New South Wales. In the collections under revision the specimens 

 with locality labels are invariably from New South Wales. The Tasmanian re- 

 cords are e^ndentlv incorrect.
