ENDYMION regalis.
Maroon banded Hair streak.
This superb butterfly, both in size and brilliancy of colour, may vie with the Emerald Hair-streak, and both are among the most beautiful of their family yet discovered. The general colour of the under surface is of the richest golden green; the under wings being crossed by a broad bar of deep maroon, softened into pearly white. The female is known by being the largest, and by having the black margin of the upper wings much broader. Our specimens were captured in Brazil. Lat 8. 12. S.

The palpi, which in the sub-genus Arcas are equally long and perfect in both sexes, are very different in the male and female of the present sub-genus. In other respects there seems to be a close affinity between them. We have not had time, however, to enter upon their minute dissection.
