Excerpt from The Journal of the Department of Agriculture of Porto Rico, Vol. 1 From time to time various entomological workers have published references to the Coccidae of Porto Rico, but the list of twenty-three species collected on the island in 1899 by Mr. August Busck is, so far as known to the writer, the only attempt ever made to enumerate the Porto Rican scale-insects. This list appeared in 1900 in Bulletin No. 22, new series, of the Division of Entomology, United States Department of Agriculture, the determinations having been made by Messrs. T. Pergande, T. D. A. Cockerell, and C. L. Marlatt. In connection with this list it is stated that only one coccid, Aspidiotus destructor, had been previously recorded from Porto Rico, this being in a reference in the Canadian Entomologist for 1895, the material having been taken by Mr. J. D. Hall in the city of San Juan. Some of the Coccidae of the island, especially those attacking citrus trees, are referred to somewhat fully in the publications of the Porto Rico Agricultural Experiment Station. In these articles Messrs. 0. W. Barrett and W. V. Tower have treated the greatest number of species and given the most extended economic accounts. Much attention has been given to the parasitic fungi attacking the scale-insects of citrus trees by the workers of the Porto Rico Insular Experiment Station. They have recommended the planting of windbreaks in orchard areas to furnish suitable conditions for the development of these fungi, which under favorable circumstances become very efficient enemies of the scale-insects. Mr. J. R. Johnston published in 1915 a bulletin on the entomogenous fungi of the island, and in it made several references to those attacking Coccidae. The insect parasites and predators of Porto Rican scale-insects have, on the other hand, received but little attention. Messrs. 0. W. Barrett, F. S. Earle, and D. L. Van Dine mention parasites of Lepidosaplies beckii, Saissetia hemisphaerica, and Aspidiotiis sacchari, respectively, but do not give their scientific names.
