cJarkii. Oil the other hand, although tlie two species differ 

 consulerubly at first sight, it has been shown above tliat the 

 two genera are closely rehited. The genital armature is in 

 agreement with this. The same six large styles are present 

 on each side, but the remaining structure is more complicated 

 than that of Neosaropogon. There is no point in describing 

 the details here. The illustrations should suffice until we 

 have material for a more complete work on the genital 

 armature of the Asilidte. 



Subgenus NKOixAwrs, Ost.-Sack, 

 Neoitamus ci/gnis, sp. n. 



Only one species of Neoitamus has been recorded from 

 Western Australia — Neoitamus rnaculatus, White, — and, since 

 White only gives tiie locality as Western Australia, this 

 means about the same as stating that one specimen of some 

 species had been found in Europe. 



There are two specimens of the new species in the collec- 

 tion. Both are females, and were caught in the suburbs of 

 Perth.
