Pamphila cusillunia sp. nov. Head and palpi above dark brown ; be- 

 neath brownish gray. Antennae black, lighter beneath. Club black, with 

 lighter tip ; beneath grayish. Thorax dark brown. Abdomen dark brown 

 above, light brown beneath. Upperside of both wings dark bronzy brown, 

 with some lustre. The discoidal space of forewings has an indistinct 

 longitudinal blackish dash. Hind margins have a slight fringe of hairs, 

 of ground color. On underside of forewings the marginal fringe is dark 

 brown from apex to centre of wing, and from that point to lower angle it 

 is grayish. On costa, one-sixteenth inch from apex, is a small white spot, 

 and in interspace below it another one, both being practically at the very 

 apex. Below these are a series of interspacial dark rust-colored dashes, 

 ending at central portion of the hind margin, most prominent near apex, 

 the apical area consequently appearing rust colored. Within these, and 

 starting at apical white spots, is a triangular space, heavily dashed with 

 white scales. The inner two-thirds of the wing is dark blackish brown. 

 The ground color of underside of hind wings is rich brown, with a suffu- 

 sing band of white. This band, with its basal side on a line drawn from 

 centre of costa to near the joint on inner margin, is pure white, suffusing 

 towards hind margin. It forms the prominent feature of the underside 

 markings. Expanse 1.12 inches. 



Hab. Bolivia, near Cusilltmi. 



Taken in May, 1899. I have placed it in the genus Pam-
