Ins. Oahu, Maui, Kauai, Lanai. (?) Imm. or aut. 
The original specimens were taken on Oahu. Examples, incapable of being satisfactorily distin- 
guished, have since occurred on Kauai, Maui, and Lanai; it is very probable, however, that the 
examination of a long series from various localities, all in good condition, would Jead tg the distinction 
of several species now included under the name of A. angusticollis. 
395. Acalles decoratus, Blackb., ante, p. 180. 
Ins. Lanai. (?) Imm. or aut. 
Unique ; taken by beating, at an elevation of about 2000 feet, on the mountains of Lanai.
