Obs. — This arrangement is that adopted by me in 1874. It is 

 possible, when the larvae of all the forms are known, it may be slightly 

 altered. The relationship between the types o{ Adelocep/iala, Boisd., and 

 the species included by me in the extension of Sphingicattipa, is not 

 known. I had been inclined to look upon Sphingicampa as a specialized 

 form with more affinity to Fades than to Anisota. I have not been able 

 to compare the larvae properly. I had endeavoured to rescue Harris's term 

 Dryocampa for Anisota rubicunda ; but the moth does not seem to offer 

 distinct structural characters ; hence, the collective term Dryocampiniy 

 G. & R., 1866, must also fall. Mr. Dyar writes me positively that he 

 thinks rubicunda strictly congeneric with Anisota., both as larva and moth. 

 The tubercles of Anisota are peculiar, and Mr. Dyar finds no difference 

 between the species. I think this settles the matter, and that the 

 present nomenclature of the Saturnina can be accepted without much 

 reservation.
