crenulated distal margins of the wings. The venation is 
practically identical, for the point of anastomosis of SC^ 
is no doubt individual; in the Catophoenissa which I have 
examined, this vein anastomoses normally with SC^‘‘ 
heyond SC^, or remains free. 
225. PSEUDOBREPHOS BAYNEI (Prout), nov. sp. 
(Plate XLVIII, fig. 10.) 
27 mm. Forewing whitish, strongl}’’ irrorated and marked 
with fuscous and dark fuscous, leaving only narrow spaces proxi- 
mally to antemediau line and distally to postmedian white, the 
latter, however, widening into a patch costally, its limit on costa 
being near apex ; lines black ; a basal, angulated in cell, reaching 
only to submedian fold ; an antemediau, oblique outwards from 
costa, making strong projections into median band in cell and in 
submedian area; a postmedian line from beyond two-thirds costa, 
strongly inbent distally to cell, sending three nearly equal teeth 
outward on R^, IVP and M^, deeply incurved in submedian area, and 
acutely angled outward on SAP ; the area between the lines rather 
uniformly dark-shaded, suggesting a median band; termen with 
black spots between the veins. Hindwing orange, fuscous-clouded 
at base and along margins as far as median band, and rather broadly 
bordered with dark fuscous; a narrow dark fuscous median band, 
outangled at posterior angle of cell, and bent towards anal angle 
posteriorly; a fine black terminal line. Underside of forewing 
whitish, somewhat sprinkled with fuscous, fuscous-shaded along 
costa, inner margin and in terminal one-fourth ; a broad dark fuscous 
tranverse bar at just beyond one-half (crossing the cell near end), and 
faint indications of a second bar margining the terminal shading 
proximally ; an orange suffusion in basal half of wing. Underside 
of hindwing whitish, sprinkled with fuscous, an angulated transverse 
band and dark border nearly as above, the latter weaker and more 
diffuse ; no orange suffusion.

I know of no second example of this pretty and interest¬ 
ing little species, which, in its general scheme of colouring, 
reminds a good deal of the Chilian Catophoenissa dihapha, 
Feld.,* in miniature.
