4 8 8 , same data as the preceding, in the writer’s collection; 
one male is destined for the collection of the Australian National 
Museum. Allotype: 5 , same data as the holotype, in Museum

Expedition to Australia, in 1931-1932. I take great pleasure 
in naming this fine stag beetle after its discoverer.
