Some years ago Rev. Edgar F. Clark, then of Providence, Rhode Island, discovered in the Coal-measures of the neighborhood of that city the wing of a cockroach. This stimulated further search by others as well as himself, with the result of finding a fair number and variety of insect types, some of special interest. Most of the discoveries have been made by Mr. Clark (part of them while in the service of the U. S. Geological Survey) and by two young inen of Providence, Messrs. Frederick P. Gorham and Herbert Scholfield, who have been particularly encouraged in their work by Prof. A. S. Packard, of Brown University.
All of the specimens have passed under my eye and are herewith described and figured. They consist of Anthracomartus, the first discovered Arachnid in the Carboniferous deposits of the eastern United States; a new genus of Neuropteroidea and one of Protophasmida, each very different from any forms hitherto found in this country, but rather allied to some from the rich Carboniferous beds of Commentry, in France, presenting new features of alliance between the Carboniferous faunas of Europe and America; and a number of cockroaches, all represented by their wings alone. These last show considerable variety of form, both known subfamilies of Paloblattarioe being present, including three genera and nearly a dozen species, the genus Etoblattina, which is the prevalent Carboniferous type the world over, being represented by at least eight species, which again show unusual diversity in size, form, and distribution of the nervules that form the framework of the wing.
All the species without exception are new to science and unknown elsewhere.
A few additional stones have been submitted to me containing what are apparently parts of the wings of cockroaches, but they are too fragmentary to be of the least value. Nothing more can be said than that they are or may be portions of such wings.
It is hoped that the publication of this bulletin will excite further exploration and result in more extended discoveries.
