Synopsis

Excerpt from A Contribution to Insect Embryology, Vol. 1: An Inaugural Dissertation

The very primitive and synthetic character of the Orthoptera has long been recognized by systematists and comparative anatomists, but the full importance of the group from an embryological standpoint has been but little appreciated, owing to the meagre and fragmentary nature of the observations hitherto published. For this reason I have made the Orthoptera the starting point of my studies, with a view to determining their relations, on the one hand to the Apterygota and on the other to the higher Pterygote orders. Only a portion of the evidence bearing on these relationships is presented in the following paper; a number of observations on the Malpighian vessels, corpus adiposum, oenocyte-clusters and abdominal appendages will be published as separate papers.

I have devoted more attention to Xiphidhim than to other Orthoptera, partly because the Locustidæ occupy a somewhat central position in the order, and partly because this curious form exhibits in its embryogeny better than any other insect hitherto studied, the co-existence of certain very ancient with very modern characters.

My German co-workers in the field of insect development will probably regard my treatment of the literature as rather perfunctory; but Prof. Graber, Dr. Heider and others have given from time to time such complete resumes of past and current literature that I feel justified in departing from the general custom.

Product Description

Excerpt from A Contribution to Insect Embryology, Vol. 1: An Inaugural Dissertation

My German co-workers in the field of insect development will probably regard my treatment of the literature as rather perfunctory; but Prof. Graber, Dr. Heider and others have given from time to time such complete résumés of past and current literature that I feel justified in departing from the general custom. If I have failed to give credit where it is due, I beg that this may be regarded as a fault of omission and not as a fault of commission.

I would express my sincere gratitude to Prof. C. O. Whit man for his kindly guidance and friendly counsel throughout the progress of my work in his laboratory at Clark University during the autumn and winter, and at the Marine Biological Laboratory during the summer months, of 1891 and 1892. I am also indebted to Mr. S. H. Scudder for the identification of several Orthoptera.
