First Supplement to the Check-list of the Coccidae.

Since the publication of the Check-List* in 1896 no less than three hundred and twenty-two species have been added. A few of these are old species which had been accidentally omitted or improperly reduced to synonyms, but the number of actually new species is very great, and bears witness to the activity of coccidologists. Forty species, given as valid in the Check-List, are here reduced to varieties or synonyms. As before, I have included a number of names of species (mostly by Green) which I know to })e either in press or awaiting very early publication.Ope
