 from costa, uneven ; outer third pale buff shaded with dark

 brown ; a broad subterminal fuscous brown line, lunular between

Heliconius galanthus, ab. SUBRUFESCENS, ab. nov. (PI. LIII.

Differs from H. galanthus Bates on the underside of hind wings; 

 the medial space below subcostal black, the fascia being reddish 

 brown, limited by a postmedial broad black line, followed by a 

 narrow brown shade having" its outer edge incurved on interspaces. 

 In H. galanthus the medial space is black edged above and below 

 with reddish brown. 



A single specimen taken on the slopes of Turrialba. Belongs
