From central India. In my own cabinet and that of the Rev.

I am indebted to my friend J. Prinsep, Esq., Secretary to the 

 Asiatic Society, for this beautiful Anthrax, as well as for the 

 Gastroxidcs ']\i?,t described. 



Obs. — This may be the Anthrax collaris of Wiedemann (Ex. 

 Dip. vol. 1, page 271), but he gives that species as much smaller 

 and as probably coming from the Cape. He describes the wings 

 as " alis nigris, guttula, excisura, apiceque limpidis," which 1 

 cannot reconcile with the wings before described, and therefore I 

 have made a new species of it.
