through the cell to near the outer margin pale cream-colour ; the 

 inner margin and the fringe cream-colour ; secondaries pale buff, in 

 some specimens almost white, with the outer margin brownish black: 

 head and thorax black ; abdomen dark bluish green ; antennae 

 black ; legs metallic green. 



Expanse 1 1 inch. 



Hab. Ecuador, Chiguinda {Buckley). 



This species is closely allied to B.. nantana. Walker, its chief 

 difference being the colour of the secondaries. I have a good series 

 of specimens of both sexes before me ; they do not show the faintest 

 trace of carmine in the hind wings.

5. Note on the Variation of certain Species o^ Agrias. 

 By P. D. GoDMAN, F.E.S., and O. Salvin, F.R.S. 



[Eeeeived May 5, 1883.] 



Since writing our paper on Agrias stuarti (P. Z. S. 1882, p. 338, 

 t. 19), Mr. A. Maxwell Stuart has again visited the Amazons, and 

 at Yquitos, where he captured the original type, has succeeded in 

 taking four more specimens, three males and one female, of this 

 magnificent Butterfly, all of which he has most generously placed in 

 our collection. 



Noticing considerable variation- in the series thus acquired, and 

 hearing that Dr. Staadinger had also recently received two specimens 

 from his excellent collector. Dr. Haluiel, from Pebas on the Ama- 

 zons, we wrote to the former gentleman asking him if he would 

 kindly allow us to see his specimens. These, together with two of 

 A. phalcidon, which will be referred to below, he has most obligingly 

 sent us. Thus, with the type of A. beatifica in the British Museum 

 and the female described in our paper from our own collection, we 

 have before us seven males and two females of these insects. 



The characters on which we relied in separating A. stuarti from 

 A. beatifica were the greater extent of the purplish-blue colour at
