weaker bill, a slightly more rounded wing, and the claw of the hinder 

 toe weaker and longer. 



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 Arthur G. Butler, F.L.S., F.Z.S., 

 Senior Assistant in the Zoological Department, British 

 Museum, and Herbert Druce, F.L.S., F.Z.S., &c. 



[Eeceived 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 Cartao-o ; 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 species, it was subsequently withdrawn.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.
