This study of Horned Beetles is by Gilbert Arrow (1873-1948). He was a notable English coleopterologist and this book, originally published in 1951, was his last work. Varieties of Horned Beetles are found in many places including Borneo and their "strangeness" has always created human interest. The beetles' habits and the differences in horn structure and usage are discussed in detail and related with the ideas and discoveries of other biologists including Wallace and Darwin. With original black and white photographs and a new bibliography, authors' and subject indexes.
