The Catalogue now submitted is intended as a companion 

 to the Preliminary Catalogue of the Lepidoptera Heterocera 

 published in the Transactions for 1901. There is a con- 

 siderable difference between the two, as the one now offered 

 is much more nearly a complete list. In it, as many as 

 289 species are enumerated, which for an island 60 miles 

 by 40 is probably unequalled. A few of the number will 

 doubtless have to be expunged, as errors of determination 

 in the first instance, but their places will probably be 

 more than filled when the last word has been said as to 

 what does really occur. The only thing of any sort that 

 has been published relative to the Butterflies of Trinidad 

 is the bare list of names by W. M. Crowfoot in " The 

 Trinidad Field Naturalists' Club" for April 1893. In 

 that list are 199 names, several of which appear to be 

 errors of determination, but in nearly every case I have 

 weighed the merits of each record, before inserting it in 

 the present Catalogue, and have indicated the probable 

 errors. The basis of the New List is my own Collection, the 

 majority of the specimens in which were personally obtained 

 in May — June 1898, and again in June — July 1901. Other 

 records are by Messrs. F. W. Urich, W. E. Broadway, H. 

 Caracciolo, J. Guppy, and several others. All the Trinidad 

 records at the Natural History Museum, besides those in 

 the Hope Museum at Oxford and those in the Godman 

 and Salvin collection have been laid under contribution, 

 the last generally from the "Biologia Centrali Americana," 

 and not from the actual specimens themselves. There are 

 few new species, which is not surprising seeing that the 

 fauna is essentially Venezuelan and Brazilian, which 

 regions have been so well worked in the last twenty years.
