Crabro {Solenius) tasmanicus, Sm. 

 Crabro tasmanicus, Sm. Cat. Hj'ui. B.M. iv. p. 425 (1856). S (as 5 ). 



This is in my opinion tlie Tasmanian race of C. tri~ 

 dentatus, Sm., the differences being mainly in colour. The 

 orange colour, so conspicuous in Australian Aculeates, and 

 of which C. tridtntatus is a good example, does not seem to 

 be indigenous in Tasmania, being confined in that island to 

 one or two large Psammocharidie such as Priocnemis bicolor, 

 Fabr., ami to the bee HyUeoides concinnus, Fabr., which are 

 probably stragglers from the mainland, where they are 

 common species.

 produced or dentate at the apex ; eyes separated at the base

 length of the scape ; front concave, not mai'gined above ; 

 second joint of the flagellum as long as the first and third

 punctured, pygidial area elongate ; posterior tibiae serrate.
