Obs. The six preceding genera are not at all typical of this subfamily, but 
I have placed them in this situation in order to maintain the passage from 
the slender-bodied tiger moths to the Lithosiide unbroken. Whereas in 
Stephens’s arrangement they interrupt this chain, whilst in Curtis’s 
Guide they are thrown out of the family after the Lithosiide.
