Twenty-one species of Lepidoptera were obtained by Mr. George Gulliver; of these, seven are Rhopalocera and fourteen Heterocera; of the latter, four are new and probably endemic forms. Twelve of the species, including the whole of the Butterflies, have been previously known from Mauritius and Bourbon, and eight of them, including six of the Butterflies, from Madagascar. All the genera, with the exception of Laverna , and eight of the species, have been recorded from India or Ceylon. The species here enumerated evidently form but a very small part of the Lepidopterous fauna of Rodriguez: in all probability many of the species which occur at Mauritius and Bourbon will be found to exist there also, of these Terias floricola and Atella columbina among the Rhopalocera, and chœrocampa celerio , Daphnis nerii , Protoparce convolvuli , Deiopeia pulchella , Plusia chalcitis , and Heliothis armigera , with several other wide-ranging species, amongst the Heterocera, may be confidently looked for.
