Fauna Simalurensis. Lepidoptera Rhopalocera, fam. Danaidae

Continuing the enumeration of the Butterflies from Simalur and neighbouring islets, collected by Mr. Edw. Jacobson, I especially call attention to the representatives of the above named family, which are very important to the knowledge of the fauna Indoaustralica. There were seven species: one of the genus Ideopsis, four of Danais and two of Euploea, of which number four were new forms. Later on I hope to publish a more detailed description of the Lepidopterous fauna of this remarkable group of islands, with the indispensable coloured plates.
