I suspect that Montrouzier's insect is a distinct species.

In the 5th Catalogue of the Museum Godeffroy, pp. 58, 59, Pieris 

 (Belenois) teutonia is reported as occurring in Viti Island, Pieris 

 (Appias) ada in the island of Yap, Pelew Islands, and Callidryas 

 (Catopsilia) minna in Ovalau. I suspect the first of these three to be 

 B.peristhene, and the third C. lactea ; "A. ada''' of the list is probably 

 distinct from the typical form, which we have.only from Am. 



In my list of the Lepidoptera collected in the South-Sea Islands 

 by Mr. Brenchley, I have included Acrcea andromacha ; I think it 

 likely, however, that the single example in the collection was taken 

 on the Australian coast.

[Received March 31, 1874.] 



In anticipation of a Monograph of the Laridce, upon which I 

 have for some time been engaged, I offer a few remarks with the 

 object of clearing up the confusion which exists respecting the
