 Hab. Oahu, Sandwich Islands. 



This species, which I consider to be distinct from 

 A. vulpiua, is described by Professor Green as inhabiting 

 the deep valleys of Oahu, at all seasons, adhering to the 

 under surface of the large leaves of a plant called Ti, from 

 the roots of which the natives brew an intoxicating bc[uor. 

 The favourite mode of preparing them for food, is to tic up 

 large numbers in the Ti leaves and bake them with heated 

 stones.

At the time Mr. Swaiuson described this species, he en- 

 tertained a doubt of its being a variety of B. BuUmoides. 



It will be found to difler in form, and the colouring is 



materiaUv diflerent.
