STUDIES IN PHILIPPINE DIPTERA, I * 



By M. Bezzi 

 (Turin, Italy) 



An extended series of studies on Philippine Diptera has been 

 made possible by copious material furnished by Professor C. F. 

 Baker, nearly all which has been taken in the vicinity of Los 

 Baiios, Laguna Province, Philippine Islands, by Julian Valdez y 

 Hernandez, Professor Baker's Cuban collector. 



It seems advisable to preface this series of papers with an 

 enumeration of the species of Diptera hitherto known from the 

 Philippine Islands. In his paper of 1882 Osten Sacken ^ brought 

 together all that was then known of the Diptera of the Islands, 

 and added much to the then scant knowledge of this region. The 

 collection studied by him contained about 250 species, only a few 

 of them described. Formerly this collection was in Turin in the 

 hands of the late Professor L. Bellardi. In the Bellardi collection, 

 now in the University Museum, some of this Philippine material 

 is yet to be found. In the general work of 1895 by Elera " 

 nothing is added to the Diptera; and but few species, except in 

 one family, have been added subsequently by Brues, Ricardo, 

 and Speiser. In one family, the Culicidse, numbers of species 

 have been described by Giles, Ludlow, C. S. Banks, and Knab.
