These drawings of beetle body parts are part of multiple pages of copies of some sort, and I would like to find the original publication of these illustrations. It seems to include tropical families as well. Thanks for any hints.
Thank you for your answer. I have another book by Harde and Severda, with indeed very similar illustrations in style and detail. However they do not cover tropical beetle families and the drawings on these plates have more variations of legs and antenna than the works by Harde. It may be a self-made combination of pictures by someone, but I hope there may be an US or Latin American book covering these exact combinations.
