XXVII. — Neiv Neotropical Geornetridae. 

 By Louis B. Prout, F.E.S. 



The types of the following species are in my collection. 

 They have for the most part been compared with the Warren 

 types in the Tring Museum, as well as with the British 

 Museum Collection and that of M. Dognin, and have been 

 submitted to the examination of Mr. Warren, who is 

 acquainted with most of the species described by Schaus and 

 Bastelberger. The literature has also been carefully used. 

 There is therefore good reason to hope that little has been 

 overlooked which ought to have been studied prior to the 

 erection of new species.
