by the distal margin contiguous to the proximal margin in an almost rectangular line; the costal margin of 

 the hindwing is somewhat concavely indented, the hindwings exhibit two very short sinall tails. Above brown 

 with a slight purple lustre, at the anal angle of the hindwing with 2 minute black dots. The 5 is somewhat 

 larger, with a more intense copper lustre. Beneath the forewings are orange in the disc, towards the margin 

 with two grey-brownish macular stripes ; the hindwings are dusty grey with numerous blurred, whitish, small spots 

 and a distinct white transverse band running straight from the costal angle to the anal angle. Ecuador, Peru. 



S. sylphis sp. nov. (144 n) I can only describe according to the only $ before me from the Collection sylpMs. 

 Fassl: the shape is the same as in the preceding species, but the colour greatly deviates above from the copper- 

 brown $ of faga: suffused with a bright blue violet, with orange-red antemarginal macular bands on both wings. 

 Beneath in the disc likewise red-yellow, the 2 marginal bands consist of distinct black small spots with white 

 rings, on the hindwing the straight whitish transverse band is absent. Cuzco (Peru). 



S. excisicosta Dyar differs from faga above by white-speckled fringes, the costal margin of the hindwing excisicosta. 

 being flatly concave like in faga, the apex projecting roundish, on the hindwing analwards 3 minute black spots, 

 proximally feeble, whitish, small lunae. Beneath the forewings are likewise orange, at the costal margin and 

 distally grey with 2 rows of dull small submarginal spots surrounded by whitish; hindwings almost grey with 

 a whitish submarginal band and very small, dull basal and discal spots; the 3 small anal spots have golden

 by a faintly darker macular line. Peru.
