PEEPACE. V 



The author has been compelled to omit from the list of Ceylonese Ileterocera the species 

 which the late Mr. F. Walker described from Mr. E. L. Layard's collection in the British 

 Museum ' Catalogue/ the types of which, however, were never in the Museum. These insects 

 were placed by him in families and genera to which they have no relation whatever, and the 

 specimens having been lost for over twenty years (as Mr. Layard informs me), there is 

 scarcely any hope that the species will ever be recognized. They will be found enumerated 

 in a separate list, as well as a few species named by T. Nietner (' The Coffee-tree and 

 its Enemies,' Colombo, 1880), of which likewise the descriptions are quite insufficient. 



A few of the Plates had been executed or printed before the manuscript of the text 

 was sent to press. As some additional materials had been received in the interval, the 

 nomenclature of some of the species was revised, and some changes were adopted in the text, 

 which are duly indicated in footuotes. 



Our best thanks are due to the generous donors whose names have been mentioned 

 above; to Mr. F. Moore, who has given to the author every assistance in allowing him free 

 access to his large collections of Ceylonese Lepidoptera ; and especially to Mr. Hampson, 

 who has spared neither time nor labour in the preparation of this Monograph.
