A KEDESCRIPTION OF THE TYPE SPECIES OF THE GENERA OF COCCIDAE BASED ON SPECIES ORIG-INALLY DESCRIBED BY MASKELL.^ By Harold Morrison and Emily Morrison, Of the Bureau, of Entomologv, United States Department of Agriculture. INTRODUCTION. As may be noted from the appended bibliography, W. M. Maskell, registrar of the University of New Zealand, began the publication of papers on tlie family Coccidae in the year 1879, and from that date until his death in 1898, an almost uninterrupted series of studies on the species of this family was produced by him, one or more articles, usualW of considerable length, appearing annually except in the years 1881, 1883, 1886, and 1888, to the number of more than 40. The earlier work was confined to the Coccid fauna of New Zealand, but before long specimens from Australia began to come to Maskell for determination, and before his work ended he had described numerous new species from that continent, from various Polynesian islands, from China, Japan, and India, from South Africa, and even from North and South America. In the course of these studies Maskell brought together a large collection of insects of this family, amoimt-ing to 597 numbers, most of which represent miduplicated species. This collection includes imstained slide mounts of nearly all the species present, and in most cases unmounted material of the same species. Unfortunately Maskell had or retained only very small quantities of unmounted material in his own collection with a ma-jority of the species. Recognizing the absolute necessit}-for a reexamination of this col-lection in the light of modern concepts if the classification of the Coccidae was to develop properly, Dr. C. L. Marlatt, Assistant Chief of the Bureau of Entomology, instituted negotiations looking to its loan for study purposes in 1906. These were continued between Doctor Marlatt, Dr. L. O. Howard, Chief of the Bureau, and Mr. T. W. Kirk, at present director of the horticultural division of the » This paper was completed and presented for pubUcation before the appearance of MacGillivray's " The Coccidae," and in consequence maket> no attempt to discuss the genotypes of some seventeen new Diaspine genera established in that work for rarions species described by Maskell.
