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 collection
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 collection
of moderate extent but of great importance, brought together
by the Chicago Natiu-al History Museum Philippine Zoological Expedition,
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.
