 fairly deep, ovipositor slightly curved upward, not reaching the anal segment 

 which is short and slightly flattened horizontally. 



Described from one male from Sydney, N.S.W., and five females, one un- 

 labelled, one fi'om National Park (December, 1905) and three from Sydney, 

 N.S.W. These specimens are in Dr. Helms' collection, now in the Bishop 

 Museum, Honolulu, T.H. One Paratype in Australian Museum Collection, No. 

 K45294. 



The interest attached to this insect is that the front legs are developed 

 abnormally for the family and indicate that the nymph is likely to be subter- 

 raneous in its habits. Infomiation on this point would be of interest and local 

 collectors should endeavour to settle this point.
