HELICONISA ARPI, new species. 
Male.—Body dark brown. Primaries, the base and costal margin 
broadly, lightish brown, sparsely irrorated with black; the iner 
margin to beyond middle and the outer margin dark brown, the latter 
with some submarginal paler brown shadings; a blackish antemedial 
shade outwardly straight from costa into cell, then inwardly oblique 
and wavy to submedian vein; a transverse black streak near end of 
cell, followed by some white, and a round brown spot on discocellulars ; 
a broad whitish postmedial space from vein 7 to inner margin near 
angle, suffused with light brown below vein 5, incurved at cell, and 
below vein 3, so that the median brown space looks very much like a 
dog’s head facing the outer margin, the spot at end of cell forming 
the eye; a narrow whitish shade extends from vein 7 to costa near 
apex. Secondaries, ochreous, the base and outer margin broadly 
dark brown; dark irrorations extending from outer margin on to 
ochreous space; underneath the primaries have the postmedial space 
broader, clearer, and tinged with ochreous, and a white spot at end 
of cell; the secondaries are paler, the ochreous space suffused with 
whitish. 
Hapanse.—95 mm. 
Habitat.—Curityba, Brazil. 
Named after Mr. J. Arp, of Rio Janeiro, to whom I am indebted 
for this fine species.
