Excerpt from Notes on the Pleurotomidae With Description of Some New Genera and SpeciesThese tribes are not all rigorously isolated or strongly de limited and there are several generic types before me which, from general appearance, may prove to be annectant or doubtfully referable to any of them, but they serve very well in a broad way and there is very seldom any doubt as to the proper reference of a species by its general facies alone. The ...

Excerpt from Memoirs on the Coleoptera, Vol. 4: 1913Our Cicindelidae have been considered more or less seriously by a number of authors recently, but the Carabidae have been singu larly neglected - even those genera composed of conspicuous species. No good tabular key to the species of Cambus or Calosoma, as represented in our fauna, has ever been published, and there is no evidence to show that the material in most of our rather numerous coll...

Excerpt from Memoirs on the Coleoptera, Vol. 8: 1918In almost every considerable collection of the Insecta, there are usually many unworked sections consisting principally of uniden tified material. This is especially true of those accumulated by students not having with them assistants to perform the more mechanical work relating to mounting and cleaning specimens and restoring such as may deteriorate through unfavorable conditions in the lap...

Excerpt from Coleopterological Notices, Vol. 4The following pages are principally confined to studies in our Rhynchophora, taken up some time since for the sole purpose of distributing the nondescript material, forming a considerable part of my cabinet, with a measurable degree of scientific order and succession.

Excerpt from Memoirs on the Coleoptera, Vol. 7: 1916One source of confusion is that the word variation is generally misunderstood and the differences due to environment so attributed. These latter divergencies do not by any means indicate variation in the proper meaning of that word, but the beginnings of separate species, at first as slightly different taxonomic forms and finally as true species. Such forms unless very distinct, as in the cas...

Excerpt from Memoirs on the Coleoptera, Vol. 9: 1920The Platyninae form an extensive and important element in the Carabid fauna of the northern hemisphere, but are very much more developed in North America than in Europe.
