The present study is a contribution to the knowledge of the external anatomy of coleopterous families. Although there have been many extensive phylogenetic studies of the Coleoptera such as Stickney (1923) on the head capsule, Williams (1938) on the mouthparts, Forbes (1922) and Graham (1922) on the wing venation, Sharp and Muir (1912) on the male genitalia, Tanner (1927) on the female genitalia and Boving and Craighead (1930) on larval characters in which parts of the various species of Rhipiceridae were described or figured there is no detailed description of a member of this family. It is intended that this study should parallel the work done by Blackburn (1936) on the Silphidae, Trimble (1935) on the Hydrophilidae, Hayes (1922) on the Scarabeidae, Rivnay (1928) on the Chrysomelidae, and Sweetman (1930) on the Coccinellidae.
