ROSENBERGIA MANDIBULARS. 11 NOTE V. On a new genus of Longicorn Coleoptera belonging to the group of the Batoceridae BY C. Ritsema+Cz. n. Rosenbergia , g. Characteristics of the but with genus Batocera, acutely produced mesosternum, entire scape which is neither in- cised nor scarred at the tip, and smooth antennae and forelegs. Moreover the apical joint of the antennae is trans- versely divided behind the middle, although not so dis- in the tinctly as genus Apriona. I have named this in honor of the well known genus C. traveller in the Malayan Archipelago Baron B. H. von Rosenberg, who has brought home one of the two species which will here be described. 1.
