A COLLECTION OF MOSQUITOES FROM THE PHILIPPINE ISLANDS (Diptera, CuUcidce) By HARRISON G. DYAR A collection of 640 mosquitoes was sent me by Prof. C. F. Baker, Dean of the College of Agriculture, Los Baiios, Luzon, Philippine Islands. The collection was made by students of the college, mostly in 1915. Thirty-two species are contained in the collection, a large number for a single locality, but probably by no means exhaustive. A recognition table of these species is added for the convenience of the college. SABETHINI Wyeomyia (Dodecamyia) mus, new species. Female.
