Biological and Taxonomic Investigations on the Mutillid Wasps

As an outgrowth of earlier work done on the genital structures of male Mutillid wasps, the author's conviction that the biology of insects is as much a factor in their taxonomy and phylogeny as morphology led him to assemble all the knowledge regarding their biology and to carry on some minor researches that were included in Part 1 of this bulletin. He reviewed 630 references, listed in the bibliography and undertook a study of the genotypes of the family, reporting the results in Part 2. This bulletin provides descriptions of multiple specimens examined.
