by Herbert T. Dalmat, Laboratory of Tropical Diseases, National Institutes of Health. Smithsonian Miscellaneous Collections, Vol. 125, No. 1 (Publication 4173) pp. I–VII, 1–452, Frontispiece, 43 plates, 13 text figures, 15 maps, 36 tables. Washington, D. C. April 5, 1955
This volume brings together the results of nearly seven years of intensive work on the black flies of Guatemala. While the bulk of the book is devoted to the more strictly entomological aspects of the subject, the whole problem of Onchocerca transmission is well reviewed, including the work done in Guatemala.
The book is planned to give as broad a picture as possible of the environment in which onchocerciasis occurs in Guatemala, so that the physical factors, plant and animal associations, and human inhabitants are all discussed in some detail, and their bearing on the transmission of the disease emphasized. The species of black flies occurring in Guatemala are treated in great detail, with keys to adults of both sexes, pupae, and larvae. Male and female genitalia of both sexes, pupal respiratory filaments, cocoons and larval structures are also completely illustrated, so that there should be no difficulty in determining any Guatemalan blackfly in the foreseeable future.
