PREFACE. 



The fifth part of this Work is devoted to illustrations of types of Indian Moths 

 in the British Museum. 



The majority of the species figured are from the region of the N.E. 

 Himalayas ; but a few forms occurring as far Avest as Almora have been 

 introduced for comparison with the more eastern species which are allied to 

 them ; also some species of which the exact locality is unknown, but which are 

 said to be from North India, have been admitted, since they were probably 

 obtained either from Silhet or Assam. 



A magnificent collection made by Dr. Lidderdale in Darjiling and Bhotan 

 and acquired for the British Museum has yielded a great number of the new 

 species described in this part. 



Some other types were received from the collection of the former India 

 Museum, and are the specimens described by Mr. Moore in the Catalogue 

 prepared by him for the East-India Company between the years 1857 and 1859. 



The descriptions of this part have been prepared by Mr. A. G. Butler, 

 Assistant-Keeper in the Department of Zoology.
