Type- — White only described the female of this species. The holotype female 

 was purchased by the British Museum with White's collection. The allotype male, 

 described above, is in the Australian Museum. There are five paratype males. 



'Note. — The collection under revision contains six males and seven females. 

 One of the females was originally identified by White, and two paii's were taken 

 in copula at Hobart and Melbourne respectively, thus establishing the sex rela- 

 tionship. All the specimens were taken by the writer.
