Mr. Louis B. Prout on the 
the entire median area occupied by a rich, dark band, mingled with 
ferruginous and bluish scales ; proximal margin of band from two- 
lifths costa, angled below SC, thence slightly oblique basewards, but 
making a slight curve distad in submedian area, reaching inner 
margin at beyond two-fifths ; outer boundary of band (postmedian 
line) from beyond two-thirds costa, forming a deep sinus distally to 
cell, oblique basewards to submedian fold, thence again forming a 
projection at SM^ reaching inner margin at beyond two-thirds ; 
band shortly followed by a thick line parallel to its outer margin, 
brownish tinted at costal end and not very distinct, overlaid with 
slaty scales from E- onward, hence more conspicuous ; diffuse obscure 
dark marks distally about R‘^ and submedian fold. Hind wing mostly 
dark, having a dark, ferruginous-tinted patch at base, a median 
band coloured as in forewing, a broad purple-bluish shade distally to 
median band as far as subterminal, redder shading from subterminal 
to terinen. Underside duller, the dark markings similarly placed, 
but uniform fuscescent, diffuse and ill-defined. 
Gran Chaco,near Florenzia, October 1902 (S. R. Wagner), 
type in coll. Br. Mus. A pretty and distinct species, which 
in its coloration and banded forewing may be very roughly 
compared with Ptychopoda (?) rusticata (Hiib.) of Europe, 
but is of much more diminutive size. 
Note. —I have a further species of Ptf/chopoda, from La Paz, 
Mendoza (VV. M. Bayne), presented by Mr. A. F. Bayne, which I 
cannot at present identify, but which is not in sufficiently good con¬ 
dition to be satisfactorily made the type of a new species, and must 
therefore wait for the discovery of supplementary material.

Mr. Warren, in erecting this species, raises a query as to 
its generic position, presumably on account of its leg- 
structure and the shape of the wings. He does not mention 
the venation, but I am inclined to suspect it will prove to 
have the areole double, and to be an aberrant member of
