Possibly other birds of this form may be found in South America ; and then it will be necessary to form them into a distinct genus. 3. List of the Butterflies of Costa Rica, with Descriptions of new Species. By A R T H U R G. B U T L E R , F.L.S., F.Z.S., Senior Assistant in the Zoological Department, British Museum, and H E R B E R T D R U C E , F.L.S., F.Z.S., &c. [Received May 16, 1874.] The present list is founded chiefly upon the large collection brought over to England a year or two ago by Dr. Van Patten, and which was perhaps the most complete that ever has or will come from that locality. It was, however, made entirely at or in the neighbourhood of Cartago ; and therefore we may still look for novelties from other parts of Costa Rica. Six new species are added in this paper. A former communication on the collection made by Dr. Van Patten was read before the Society in July 1872 ; but as we wished to make it a complete list, and to add a few notes on some of the species, it was subsequently withdrawn. The Moths collected by Dr. Van Patten being almost all day-fliers, would give but a poor idea of the Heterocerous fauna of Cartago, not to speak of Costa Rica ; and as we have neither time nor inclination to collate the whole of the descriptions of species in this suborder, we have not included any of them in the present paper.
