 PI. xii., figs. 5, 6. 

 The type of this species was stated to be in Mr. C. 

 French's collection ; in that collection (now in Melbourne in 

 the National Museum) there were three specimens standing 

 under that name/ 5 ) but Blackburn's original label has been 

 removed; one specimen (a female) was specially labelled by 

 Mr. French, and as it is the only one of the length (10 J lines) 



(3) The type and only known specimen is a female. 



(4) On most specimens of flavifrons the dark subapical mark- 

 ings terminate at or near the suture, but on one specimen the 

 suture itself is infuscated. 



(5) By the courtesy of Mr. J. Kershaw I have been able to 

 .examine then).
