 into one. It is probable that a ion-«iilerable proportion of tju' >p«Ti«'s that liavi- Iw-en 

 deHtrilMHl are invalid (set- Arrow, l!Mt7. p. 443). 



The remaining species, though tindoiibtedly numerous, probably require proportionally 

 still more drastic nnluction of their numbers. It seems to be impossible to separate 

 them into groups having the siinie value as the genera mentioned above. (Vmsequently 

 I pro|>nse to regard almost all of tlicni as constituting a single large and plaMtie genus 

 I'assiihis. 



The only exception is the genus I'hrhofins, tin- la^t and in some respects the most 

 highly specialize*! genus of the subfamily. It may readily be recognized fnnii all others 

 by the remarkable structure of its mandibles. 



The genera of Pa-ssaliiiac known to ine may be separated thus :
