While the most advanced technological means to photograph and reproduce this document have been used, the quality is heavily dependent upon the quality of the original submitted. The following explanation of techniques is provided to help you understand markings or patterns which may appear on this reproduction. 1. The sign or "target" for pages apparently lacking from the document photographed is "Missing Page(s)". If it was possible to obtain the missing page(s) or section, they are spliced into the film along with adjacent pages. This may have necessitated cutting thru an image and duplicating adjacent pages to insure you complete continuity. 2. When an image on the film is obliterated with a large round black mark, it is an indication that the photographer suspected that the copy may have moved during exposure and thus cause a blurred image. You will find a good image of the pa^ in the adjacent frame. 3. When a map, drawing or chart, etc., was part of the material being photographed the photographer followed a definite method in "sectioning" the material. It is customary to begin photoing at the upper left hand corner of a large sheet and to continue photoing from left to right in equal Sections with à small overlap, if necessary, sectioning I? continued again — beginning below the first row and continuing on until complete. 4. The majority of users indicate that the textual content is of greatest value, however, a somewhat higher quality reproduction could be made from "photographs" if essential to the understanding of the dissertation. Silver prints of "photographs" may be ordered at additional charge by writing iiic VIUGF iiiiciii, yiviiiy uic uaiaiuy liuniuBf, liUB, BiJincr âiîù specific pages you wish reproduced. 5. PLEASE NOTE: Some pages may have indistinct print. Filmed as received.

Only a few papers, mainly listings, descrip tions of new species and scattered economic reports have recorded the West Indian muscid fauna. The works of Wolcott (1923a, 1923c, 1924, 1933, 1936, 1941, 1948, and 1955); Curran (1928); Snyder (1940, 1954a, 1954b, 1957a, 1958a) and Albuquerque (1945, 1953, 1954a, 1954b, 1955, 1956a, 1956b, 1956d, 1958a, 1958b, 1959) have served Puerto Rican zoologists as authoritative works of reference for many years. Wolcott (1948) listed the Puerto Rican insects including the Muscidae, with some annotations on their biology and taxonomy, but little has been added to this subject since then. Due to the lack of adequate information on the local species in this family, it is apparent that further studies should be pursued. The writer is convinced that bringing together the hitherto scattered information and the search for new taxonomic and morphological data concerning the species would not only be desirable, but a very practical undertaking. Other objectives of the work are; 1) to properly identify the members of the family Muscidae occurring in Puerto Rico; 2) to compile the meager literature on the muscids of the island; 3) to bring up-to-date the synonymy of the local muscid species; 2 4) to clarify old concepts, as well as bring up some new perti nent facts about the general morphology and other general characteristics of the
