A second instalment of a proposed new Catalogue of N. American 
Diptera. The number of described species of SyrpliidcB north of Mexico 
and exclusive of California, is about 160 ; from California only 11 are 
known. With a few exceptions (all small genera), all the European 
genera occur in N. America, and most of these common genera are 
much richer in species in Europe. 11 genera are peculiar, to N. America, 
and 25 species are common to Europe and N. America. 
The Catalogue contains bibliographical references and localities, with 
synonymical and other incidental observations. Other notes are given, 
p. 63, and a new genus and 8 new species characterized. Corrections are 
made in the author’s former papers [Zool. Rec. xi. pp. 445 & 446]. 
Syrphus. The 11 known N. American species of this (restricted) genus 
are described and tabulated : S. umbellatarum, L., ahbreviatus and lapJ- 
ponicus, Zett., occur also in Europe ; S. diversipes, Macq., ? = cinctellus^ 
Zett., topi’anas, Zett., nec Meig., renamed torous, p. 139, and anew
