This species is common on Kauai, Onlni, ]\[aui and Hawaii. 

 The caterpillars feed upon Erythrina monosperma ( 'Wiliwili' ' ) , 

 Dolichos lablab, and several species of wild beans with long twin- 

 ing vines in the woods of the mountains. I have also found them 

 on garden beans in Honolulu. They fold over (or under) a 

 portion of leaflet, and fasten witli silk, or fasten two leaves 

 together ^vhere their surfaces are in contact, and feed \vithin, 

 eating away the substance of the leaf and leaving the outer epid- 

 ermis. Pupation takes place where the caterpillars have fed.
