| Seven species of the scarab genus Onthophagus Latreille are keyed and described. They are all characterized by the possession of large eyes (in full-face view), a feature possibly related to nocturnal habits. Traditionally these species are placed in Micronthophagus Balthasar, which is here argued to be a polyphyletic group. Five species are new: paroculus (Sumatra), setoculus (Sumatra), sideki (Sumatra, Borneo), phillippsorum (Borneo), collinsi (Borneo). Of two old species, O. drescheri Paulian and rotundicollis Lansberge, new records are given. |

| Protected beetles in the Netherlands (Coleoptera) The status of all by law protected beetles of the Netherlands is discussed. Several specimens of Cerambyx cerdo are known from the Netherlands, but all of these are considered to have been imported with oak-wood. Taking the European distribution into account it is supposed that Cerambyx cerdo once inhabited the Netherlands, but became extinct centuries ago as a result of the disappearance of suitable oak-trees. Both Osmoderma eremita and Dytiscus latissimus were very rare during the last two centuries. Only few specimens from isolated localities were collected in the 20th century, hence they are now considered extinct in the Netherlands. Graphoderus bilineatus was not uncommon in the beginning of the 20th... |

| The distribution of the genus Cercyon Leach in the Netherlands has been examined. A survey of characters and character-states is provided. Keys to species and supraspecific taxa are given. The distribution of each species is mapped and the male genitalia are figured. It is noted that the presence or absence of an emargination at the apex of the prosternum is an important character in the supraspecific classification of the genus Cercyon. The presence of male adherence discs at the maxillae is not unique for the tribe Cercyonini, but occurs also in the tribes Sphaeridiini and Megasternini. C. laminatus Sharp is placed in the subgenus Paracycreon d'Orchymont. C. alni Vogt is placed in synonymy with C. convexiusculus Stephens. A lectotype is designated for... |
