Excerpt from Report Upon a Collection of Coccidae From Lower California In certain fields enough work has been done to give a reasonably clear conception of the nature of the life of the peninsula, but there remain some groups that have been practically untouched. Among these groups are the insects. Rather extensive entomological collections were made by Dr. Eisen in the southern portion of the peninsula, the region to which scientific writers have applied the name Cape Region, but even here practically no more than a beginning has been made. Throughout the remainder of the area almost no work at all has been done and con cerning certain groups there is no information whatsoever. From all this great area, as far as I am able to determine, not a single species of the Coccidae or scale insects has heretofore been recorded, although the richness of the ora is in itself evidence that this group Should be well represented. A few species have been taken from Carmen Island in the Gulf of California, but none from the peninsula itself. The present writer has long been keenly aware of the possibilities of extending our knowledge of these insects by explorations within this region. With the financial support of the california-academy of Sciences, the Department of Entomology of Stanford University and the United States Bureau of Entomology, it became possible to spend some time during the summer of 1919 in the southern portion of the peninsula for the purpose, in part, especially of collecting these insects. It is upon the results of this work that the present paper is based. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Excerpt from Papers on Coccid or Scale Insects: The National Collection of Coccid ; Issued April 23, 1908 Doctor Howard, while assisting Professor Comstock in the study of Cocciclae, took up particularly the subject of the chalcidid para sites of these insects, and presented as Part III of Professor Com stock's report a paper entitled Report on the Parasites of the Coccidae in the Collection of this Department. This was the begin ning of Doctor Howard's work on chalcidid parasites and led to his becoming the world's authority on the subject. How little was known of these parasites previous to the publication of this paper is shown by the fact. That, with four or five exceptions, the species described and figured were new to science. Professor Comstock retired from the position of Entomologist in 1881, but published in Professor Riley's Report for that vear a short illustrated article on Lac Insects, describing three new species. He also gave a brief article on methods of controlling scale insects. A much more important article on remedies for scale insects of the orange, by Mr. H. G. Hubbard, is published in the same report. In this paper some very good work is recorded and some of the more important modern methods of control are given first exploitation.

Excerpt from Papers on Coccidae or Scale Insects: The National Collection of Coccidae Mr. H. G. Hubbard, who has already been referred to as having published an important paper on remedies for Coccidae in the Annual Report of the Department for continued his investigation of orange insects and the means of controlling them, at Crescent City, Fla, as an agent of the Department of Agriculture, and published in 1885 his excellent report entitled Insects Affecting the Orange. This represented nearly four years' study and experiment, and dealt very largely with the common scale enemies of the orange. Mr. Hub bard's interest in scale insects, aroused in this study, continued, although he published nothing noteworthy afterwards on the subject. It was, however, his intention to bring out a new and thoroughly revised edition of his Orange. Insects, and to take up in connection with it a study of the classification of, Coccidae; but his untimely death prevented the accomplishment of this task.
