Excerpt from The Wings of Insects: An Exposition of the Uniform Terminology of the Wing Veins of Insects and a Discussion of the More General Characteristics of the Wings of the Several Orders of Insects

Many investigators have contributed to the attainment of this result. A brief review of their more important publications on this subject is given in Chapter I of this work.

As these publications are widely scattered through various journals that are to be found only in the larger libraries, most of them are inaccessible to many who wish to Obtain an understanding of the uniform terminology and Of the reasons that have led to its adoption. There is, therefore, a demand for a comprehensive exposition of this terminology, and for a statement of the facts upon which it is based. It is to meet this demand that this book is Offered to the public.

I undertook the preparation of this treatise upon the earnest solicitation Of many co-workers in entomology, and with the feeling that the great amount Of work, extending over a long period, that I have devoted to this subject made it appropriate for me to do so.

It is now more than thirty years since I began a special study Of the homologies of the wing-veins Of insects, a subject in which my interest had been awakened a decade before by my teacher, Dr. Hagen.

My first effort to Solve the problem was undertaken in the course Of the preparation Of an article on the Hymenoptera published in The Standard Natural History in 1884. Much time was devoted to the subject, but without the attainment Of any results that seemed worthy of incorporation in that article. With our present knowledge of the subject, it is easy to see how hopeless was the attempt to solve the problem by beginning with a study of the highly specialized wings Of the Hymenoptera.

Excerpt from The Wings of Insects: An Exposition of the Uniform Terminology of the Wing Veins of Insects and a Discussion of the More General Characteristics of the Wings of the Several Orders of Insects

During the last forty years. much attention has been given to the development of a terminology of the wing-veins of insects that should be available in the descriptions of insects of all orders, and that should replace the many systems that have been devised by specialists, who have restricted their studies, in each ease, to a single order. There has resulted from these efforts the perfection of a uniform terminology, which is being very generally adopted, and which will doubtless supersede the many systems still in use.

Many investigators have contributed to the attainment of this result. A brief review of their more important publications on this subject is given in Chapter I of this work.

Much time was devoted to the subject, but without the attainment of any results that seemed worthy of incorporation in that article. With our present knowledge of the subject, it is easy to see how hopeless was the attempt to solve the problem by beginning with a study of the highly specialized stings of the Hymenoptera.

A few years later I attacked the problem again; this time by a study of the wings of the Lepidoptera. This was a more fortunate starting point; and considerable progress was made. The results of these studies were published in 1892 and 1893. The results obtained by further studies of the wings of the Lepidoptera and by a study of the wings of the Diptera and Hymenoptera were included in a text book published in 1895.
