Book Description
Excerpt from Record of American Entomology: For the Year 1868 The year has been one of very considerable activity among our entomologists, as evinced by the appearance of two monthly journals devoted purely to entomology - the "American Entomologist" and the "Canadian Entomologist" - and the large space devoted to popular entomology in the "American Naturalist." There is no doubt but that the collection and description of species in the various groups, and the study of practical or economical entomology, including bee-keeping, will go on making great advances and producing most important results. But it is to the less frequented fields of research that we would draw the attention of entomologists. In the art of bee-keeping Americans are rapidly becoming the most practised and expert hands; but for the science of this art we are indebted to German and French physiologists and embryologists. Our entomologists need to pay more attention to the anatomy, physiology, and to the study of the development of insects, especially as bearing on the subject of parthenogenesis.
