Zoological Journal published in Java. I am unable to refer to this work, but have adopted the names with which he has ticketed the species in Mr. Wallace’s collection.

Heliomeia has the aspect of Leptis, but is distinguished by the subanal and anal veins being united before they join the border of the wing, thus agreeing with Chrysopila, from which it differs in the shorter third joint of the antennz, and in the more slender arista.
