109 species and 2 subspecies are also described as new. 



The moths described in the following pages were very carefull}^ 

 collected by Mr. Walter Feather, who preserved excellent data. 

 Sir George Hampson has described the new species of all 

 the groups except the Sphingidfe, by Dr. Karl Jordan, the 

 Geometridee, by Mr. L. B. Prout, and the Tineina, by Mr. J. H. 

 Durrant. The order of the species is from the more specialised to 

 the more generalised except in the Geometridse, which Mr. Prout 

 has arranged in the opposite sequence. 



Types of the species described by Sir Geor-ge Hampson and 

 Mr. Durrant are in the collection of the British Museum, co- 

 types, when the series permits, in the Hope Department, Oxford 

 University Museum, and Mr. Feather's collection. Dr. Jordan's 

 and Mr. Front's types are in the Hope Collection, co-types, 

 when the series permits, in the British Museum, Mr. Feather's 

 collection, and that of the describer. This statement renders 

 unnecessary any further refei"ence to the disposition of types and 

 co-types in the descriptive part of this memoir.
