I have a lot material from other families on the periphery of my chief interest. It is mostly taxidermy material (captured mostly but not exclusively by me) mostly from Europe. Material from the superfamily Scarabaeoidea is from the whole Palearctic. The most extensive part is from China, the Himalayas, India, Pakistan, but also Tanzania, Etiopia and other similar locations. I myself will never complete the work on this group so there is a possibility of both personal consultation and exchange. As regards the species of the Scarabaeidae family, we can agree on exchange if the list includes two specimens of the same gender.
