Bothynus nyx Ratcliffe, new species, is described from Bolivia with supporting illustrations. A key to the five species of Bothynus Hope known to occur in Bolivia is provided.

The female of Ceraspis jaliscoensis Delgado and Navarrete-Heredia is described and illustrated for the first time. A key to the Mexican and Central American species of Ceraspis LePeletier and Serville is presented.

Physopleurus swifti Chalumeau, new species, from Brazil is described, illustrated, and compared with Physopleurus rugosus (Gahan), to which it is similar in appearance.

Athous (Orthathous) yozgatiensis Kabalak and Sert, new species, from Yozgat, Turkey is described. Photograph of the adult, drawings of the antenna and aedeagus, a key to the new and closely related species, a distribution map, and differential diagnosis table are given. The new species is similar to Athous kovancii Platia and Athous fragariae Platia and Kovanci, but is distinguished clearly by the second antennal segment slightly longer than wide, third antennal segment longer than second, and broadly rounded apex of parameres.

Acanthoscelides delgadoi new species, collected in Nuevo León, Mexico, is described and illustrated. A key to the obtectus species-group is provided.

We examined the reproductive systems, including genitalia, of 10 species of Geotrupini from Mexico. Females of all examined species have six ovarioles in each ovary. Spermathecae and genitalia of all species are similar. The genital plates show marked morphological differences at the species level, and thus may be useful as specific characters in taxonomic studies. Males of all of the examined species have six follicles per testicle. The aedeagus is variable across species and is used to distinguish species.

The third instar of Phytholaema herrmanni Germain and Phytholaema dilutipes (Fairmaire and Germain) (Scarabaeidae: Melolonthinae) are described and illustrated. The larvae were reared under laboratory conditions from eggs laid by adults and larvae collected from pasture soil. This is the first description of larvae of the genus Phytholaema Blanchard. The larvae of both species have a vestigial sclerotized structure on the pleura of A9 and many other similar characteristics. The similar size of abdominal spiracles A6 and A8 in P. dilutipes is key to differentiating it from P. herrmanni, which has spiracle A8 smaller than spiracle A6.

The Neotropical skiff beetle genus Yara Reichardt and Hinton is recorded from Venezuela for the first time, marking the first discovery of the genus since its original description in 1976. The Venezuelan species, Yara maculata Short, Joly, and Garcia, new species, is described and illustrated, bringing the total number of species in the genus to three. It is currently known from several localities along the northwestern edge of the Guiana Shield. The presence of a mat of recumbent setae on tergite IV, often considered diagnostic for the family, is found to be absent in Yara. A key to the three species is provided as well as observations on the habitat and seasonality of the new species.

The 100^th anniversary of the publication of W. S. Blatchley's An Illustrated Descriptive Catalogue of the Coleoptera or Beetles (Exclusive of the Rhynchophora) Known to Occur in Indiana is observed. Reasons behind this classic monograph's enduring utility are explored. In addition, the volume's origin, projected audience, and relationships to later identification manuals are examined, along with Blatchley's other major entomological contributions. Blatchley's Coleoptera in Indiana became a model for several regional studies and was not superseded for close to 90 years.
