PREFACE. 
Tue 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 west 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 1899. 
‘The descriptions of this part have been prepared by Mr. A. G. Butler, 
Assistant-Keeper in the Department of Zoology.
