| Three genera are diagnosed and discussed: Pseudopilinurgus Moser, Callynomes Mohnike (= Praona Westwood, syn. nov.), and Anatonochilus Péringuey. Their species are keyed and mentioned in annotated checklists. The Leiden material is recorded. From other collections three new species are described: Pseudopilinurgus erratus from Rhodesia, Callynomes apo from the Philippines, and Anatonochilus pletus from Tanzania. Cremastocheilus cribrosus Gory & Percheron is transferred to Pseudopilinurgus; Coenochilus luzonicus Schultze is transferred to Callynomes. For two names lectotypes are designated. |

| A revised key to the subfamilies, tribes and subtribes of the Cetoniidae (Coleoptera: Scarabaeoidea) is presented. Comments are given on the classification implied by the key, which includes several redefinitions. All the known genera (ca. 510) are listed under their tribe or subtribe, the position of several being different from that in Schenkling's catalogues (1921, 1922). References to recent synoptic literature are given. Eighteen new subtribes are proposed, the majority in the tribe Cremastocheilini. One new tribe is proposed, the Platygeniini. Attention is drawn to various new and neglected synonymies, original spellings, and other nomenclatural matters regarding family-group and genus-group names. The position of many genera is briefly discussed.... |

| About twenty years ago MARTÍNEZ proposed some new genera for the accommodation of a number of aberrant South American aphodiid beetles, until then placed in Euparia LePeletier & Serville. In 1951 he referred two species, Euparia costulata Harold and E. ovalis A. Schmidt, to his genus Lomanoxia, recognizable i.a. by having the sides of the elytra acutely inflexed. As these scarabs are exceedingly rare in collections, I was delighted at finding specimens referable to Lomanoxia among some material collected from the nests of leafcutting ants in Surinam; one represents a species new to science. My unsuccessful efforts to trace the type of Euparia costulata Harold in the Paris museum were compensated by the recovery of additional specimens of Lomanoxia, one... |

| Five species are placed in the Bolboceroides validus group, which is diagnosed. Four of the species are transferred from Bolboceras, viz. Bolboceras serripes Fairmaire, B. validum Klug (= rollii Müller), Β. carinicolle Laporte (= Β. capitatum Westwood, syn. nov.), B. scotti (Paulian); Bolboceroides kubaricus sp. nov. (Yemen) and B. serripes tsavoensis subsp. nov. (East Kenya, Somalia) are diagnosed. An illustrated key to the males is given. For Bolboceras carinicolle Laporte and B. capitatum Westwood lectotypes are designated. New records are given. In a footnote the synonymy of the names Bolboceras and Odonteus is briefly discussed. |

| A key to the Asian cremastochiliform genera is given. Three synonymies are emphasized: Clinterocera Motschulsky (= Callynomes Westwood); Campsiura Hope (= Macroma Gory & Percheron); Spilophorus Schaum (= Pseudospilophorus Kraatz). A new synonymy is: Periphanesthes Kraatz (= Bonsiella Ruter). The authorship of one species is established: Praona niveosparsa (Mohnike). The publication dates of Westwood's Thesaurus Entomologicus Oxoniensis are discussed. The type-material of the Leiden museum is listed; six lectotypes are designated. Two new species are described and illustrated: Campsiura celebensis (Sulawesi) and Parapilinurgus hiekei (Assam). |

| Two Asian genera are diagnosed and their nomenclature is revised: Pleuronota Kraatz (= Macronotiola Mikšić, syn. nov.) and Macronotops nov. (= Pleuronota sensu Mikšić). Key frameworks for both genera and checklists of the known species are given. Pleuronota alleni sp. nov. (Borneo) is described and illustrated. Some new records are given. The following new combinations had to be made. To Pleuronota: aenea (Gestro), elongata (Gory & Percheron), longiuscula (Moser), monticola (Gestro), rufosquamosa (Fairmaire), setosa setosa (Moser), setosa imuganica (Mikšić) (all from Macronotiola), patricia (Gory & Percheron) (from Macronota) ; to Macronotops: fulvoguttata (Fairmaire), fulvopilosa (Fairmaire), nigropubescens (Mikšić), ovaliceps (Arrow), sexmaculata... |

| Heterovalgus popei (Java) and Tibiovalgus perplexus (Cameroun), new genera and species, are described and inserted in a key to the known genera of Valginae. A checklist of valgine genus-group names is given, including details about type-species, synonymies, number of species per genus, and occurrence in zoogeographical regions. For six old genus-group names type-species are designated. |

| Two new genera, endemic in southwestern Africa, are diagnosed: Prototrupes, for Bolboceras copridoides Kolbe (type-species) and Bolboceras kochi Paulian; Namibiotrupes for Namibiotrupes penrithae sp. nov. The species of Prototrupes are keyed, illustrated, and some new material is recorded. Namibiotrupes penrithae from the Namib Desert Park is described and illustrated. The two genera are characterized by enlarged antennal clubs. |

NL - Het aantal in Nederland vastgestelde soorten, de hoeveelheid daarvan die niet echt inheems is, en eventueel het aantal alleen uit ons land bekende soorten en het aantal (nog) te verwachten soorten (d.w.z.: waarschijnlijk in Nederland aanwezig, maar nog niet ontdekt), met bronnen. Eventueel zijn de bij ons soortenrijkste deelgroepen (meestal families) vermeld of is een overzicht van de groep in tabelvorm toegevoegd.

Cyclidinus velutinus Westwood, the distribution of which appears to be Neotropical, is accommodated in Cyclidiellus gen. nov. A brief revised key to the New World genera of Cremastocheilini is given; Uloptera Burmeister is excluded, being Ethiopian, the new genera and the neglected Cyclidinus Westwood are included. |

| Onitini collected in East Africa (mainly southeastern Kenya) are discussed. The distribution of onitine species over Kenya, Tanzania, Uganda, and Tsavo National Park is reviewed (table 1). Three new species and one new subspecies are described and illustrated, viz., Onitis bispicticollis, kingstoni, pseudojansenii, sulcipennis subsp. naromorus (all from Kenya). For species described from other parts of Africa lectotypes are designated, viz., Onitis obscurus Lansberge, vanderkelleni Lansberge, vethi Lansberge (junior synonym of fabricii Roth), westermanni Lansberge. Onitis decellei Frey is a junior synonym of 0. violaceus Lansberge and a junior homonym of 0. decellei Paulian (junior synonym of viridulus Reiche). Further notes concern identification,... |
