| Resumo: |
Having received from Mr. A. L. van Hasselt of Padang Sidempoean, among some other interesting beetles from Sipirok (North West Sumatra), a couple of a beautiful Calandrid of the group Rhynchophoridae, viz. Macrocheirus spectabilis Dohrn, I carefully examined the materials of this group in the Leyden Museum, and this examination convinced me of the necessity of dividing Schönherr’s genus Cyrtotrachelus in two genera. The following table will clearly show the distinctive characteristics of the genera of the first division of Lacordaire’s group Rhynchophorides (Genera des Coléoptères. Tom. VII. p. 271): a. Elytra distinctly narrowing backward, conjointly emarginate at the end.
