scarcely traceable. The prothoracic excavation of the male is of 
small area but moderately deep.

Superficially this species closely resembles J. pecwarzws, Reiche, 
puncticollis, Macl. and Meyricki, Blackb., and it would certainly 
be most unnatural to separate it from them generically—never- 
theless its claw structure places it with J levipennis, Blackb., 
and bidens, Blackb., which if I had not seen this species I should 
be disposed to regard as generically distinct from J pecwarius, 
we. The prothoracic excavation in this species is large and deep 
as in 1. Meyricki.

This genus is distinguishable from the other Australian 
Dynastides by the following characters in combination, viz., 
prothorax not simple in either sex (a tubercle or horn on the 
front margin in both sexes), hind tibiz strongly ciliated at apex, 
basal joint of hind tarsi only moderately dilated at apex, club of 
antenne not extraordinarily developed, front tibie externally 
bidentate or scarcely dentate at all in the male (tridentate in 
the female), one of the two apical spines of the hind tibie
