Book Description
Excerpt from Annals of the Entomological Society of America, Vol. 8: June, 1915 An insect that belongs to a country through inheritance, and one that it obtains through migration or dispersal, each may Spread over that country and exist side by side; or each may be restricted to a very narrow range. The many cases of insect introduction in historic times show that great numbers of insects not now occurring here, could live and thrive with us.

Excerpt from Annals of the Entomological Society of America, Vol. 8: September, 1915 In many sections at this age, and later, there can be found running through this middle layer small darker dots and short lines which would correspond to the middle membrane of other Observers (fig. These are more or less distinct in different sections but do not show continuously for any great distance in any section and we are unable to find any regular structure strictly homologous to a membrane. The strands of proto plasm which connect this middle layer to the outer layers will be spoken of as the perpendicular strands.

Book Description
Excerpt from Annals of the Entomological Society of America, Vol. 8: 1915 At this point I shall have to appeal to your courteous patience for permission to present a few elementary definitions, a rehearsal of which seems to me necessary to avoid possible ambiguity, uncertainty, or misunderstanding; especially so as the animal ecologists themselves are not by any means in exact accord as to the scope, description, subdivision, and nomenclature of their subject. Let us agree, then, that, for the purposes of this discussion at any rate, the subject matter of ecology may be defined as the relation of organisms to their environment, and that this means the whole environment, organic and in organic, and any and all organisms, man included - man, in deed, as by far the most important living factor, from whatever point of View. And let us also understand that the relations meant are, first, relations of interaction - dynamic relations, of efficient cause, and effect produced upon the organism by its environment and upon the environment by the organism; second, space relations, of distribution, position, juxtaposition, and association - static relations, we may call these, since they Show the status of an individual or a group at a given time with reference to the various objects of its environment; and third, successional relations, time relations, sometimes called genetic because, in showing the static relations of a group in successive periods, they trace the genesis of the present status.

Book Description
Excerpt from Annals of the Entomological Society of America, Vol. 8: March, 1915 The staining of the material for dissection with safranin proved to be very useful in differentiating the almost colorless mouth - parts of some of the species. In using aniline oil in any form one precaution must be observed; as much as possible of the oil should be removed with a blotting paper or a dry rag or by replacing the carbol-aniline oil with carbol-xylene or xylene before mounting in balsam. If the oil be not removed the media in which the parts are immersed will eventually darken. Material for sections was fixed with hot (80° C.) corrosive sublimate (saturated corrosive sublimate in 35% alcohol plus 2% of glacial acetic acid) for 15 to 30 minutes, which was replaced by 70% alcohol containing a few drops of iodine for 24 or more hours.

Book Description
Unlike some other reproductions of classic texts (1) We have not used OCR(Optical Character Recognition), as this leads to bad quality books with introduced typos. (2) In books where there are images such as portraits, maps, sketches etc We have endeavoured to keep the quality of these images, so they represent accurately the original artefact. Although occasionally there may be certain imperfections with these old texts, we feel they deserve to be made available for future generations to enjoy.
