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 InsectsMany 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.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.

Not illustrated. 1918 Excerpt: ...longitudinal line: "a) The radial planate traverses the interradial area, crossing the branches of the radial sector, in the direction of the wing apex. See Figure 202. "b) The trigonal planate traverse the area of the trigonal fork, crossing and uniting the branches that spring from the trigonal vein, to which vein it is more or less closely parallel. The trigonal planate is more or less closely joined at its proximal end to the trigonal arc. "8. A median nexus or conjunction of adjacent veins, joins the tip of vein M1+2 with the vein on each side of it, and an interradial nexus in the more specialized Palparinae similarly joins the tip of the first and second branches of the radial sector. (5) THE WINGS OF THE ASCALAPHIDS Although the family Ascalaphidae is distinctly separated from the Myrmeleonidae, the wings of ascalaphids resemble quite closely those of the myrmeleonids. The only feature that sharply distinguishes the wings of ascalaphids from those of myrmeleonids is the fact that in the Ascalaphidae there is no greatly elongated cell behind the point of fusion of veins Sc and Ri. In the Ascalaphidae, the obliquity of the base of vein M3+4 is frequently not well-marked; it is obvious in Ululodes hyalina (Fig. 203, o), but in. Ogcogaster tesselata (Fig. 204) it is less so. In this family the radial cuneate area is always present, although in a few cases, as in the genus Paer, it is small. It is in nearly all cases irregular in form, as in Ululodes (Fig. 203), appearing to be behind the first branch of the radial sector; rarely it has the appearance of being between two forks of the first branch of the radial sector. One of the best examples of this is in the wings of Ogcogaster tesselata from India (Fig. 204). In the hind wings the medi...

This book was originally published prior to 1923, and represents a reproduction of an important historical work, maintaining the same format as the original work. While some publishers have opted to apply OCR (optical character recognition) technology to the process, we believe this leads to sub-optimal results (frequent typographical errors, strange characters and confusing formatting) and does not adequately preserve the historical character of the original artifact. We believe this work is culturally important in its original archival form. While we strive to adequately clean and digitally enhance the original work, there are occasionally instances where imperfections such as blurred or missing pages, poor pictures or errant marks may have been introduced due to either the quality of the original work or the scanning process itself. Despite these occasional imperfections, we have brought it back into print as part of our ongoing global book preservation commitment, providing customers with access to the best possible historical reprints. We appreciate your understanding of these occasional imperfections, and sincerely hope you enjoy seeing the book in a format as close as possible to that intended by the original publisher.
