importance, originating from various places on the island of Panay 

 and stray specimens from other locahties. 



The otherwise outstanding and extensive collection of the British 

 Museimi contained but few specimens of Microlepidoptera from the 

 PhUippines. An exception, however, was the collections of unnamed 

 material originating from Lord Rothschild's bequest. They were 

 transferred recently from the Tring Museimi to London, where I first 

 saw them in 1963. This material appeared to contain several himdred 

 specimens of Philippine Microlepidoptera collected in 1912-1914 by 

 A. E. WHeman for Lord RothschUd. This interesting material was 

 borrowed and studied in Leiden along mth the other collections. 



Dm-ing a stay in the Philippines in 1945, Dr. J. G. Franclemont, 

 of the Department of Entomology, Cornell University, Ithaca, N.Y., 

 collected several interesting species at light on Luzon. A small col- 

 lection was received from the P. Bernice Bishop Museum, Honohdu; 

 another was selected by the author from the collection of the Carnegie 

 Museiun (CMP) when staying in Pittsbm'gh, Pa. Finally, a col- 

 lection of moderate extent but of great importance, brought together 

 by the Chicago Natiu-al History Museum Philippine Zoological Ex- 

 pedition, 1946-47, was received from that museimi and could be 

 worked. 



The additions mentioned above were received after the start of 

 the original work. However welcome, they unavoidably caused 

 considerable delay to the termination of this project.
