64 SUBFAMILIES CYPHALEIS.K AND CS0DAL0X1X.E, 



Coll., (Geneva 1), and as Westwood gives Swan River as its 

 habitat, whereas Mterodes is, I believe, confined to East Aus- 

 tralia, there is a doubt which can only be removed by reference 

 to the actual type. Tt is certain, however, that M. Westwoodi 

 Macl., and the new species, M. Kershawi, are not congeneric with 

 M. Mastersi Pasc.
