MAIIAKAMIA KAMPMEINERTI. 



NOTE IX. 



A NEW GENUS AND APPARENTLY NEW SPECIES 

 OF RHYNCHOPHOROUS COLEOPTERA, 



DKSCniBED BY 



C. RITSEMA Cz. 



In tliu following lines a very interesting new genns of 

 the group Rhynchophoridae will be established. A single 

 male specimen, from the Upper Mahakam (Borneo), has 

 been found in a small collection of natural history objects, 

 presented to the Leyden Museum in December of last year 

 by Mr. Kampmeinert. The species is dedicated to the donor. 



The nearest ally of this new genus, for which I propose 

 the name MaJiakamia, is Macrocheinis Schönh. The cha- 

 racters by which the two genera are differentiated in the 

 male sex (the female sex of my insect is as yet unknown) 

 are very conspicuous, as will be seen from the following table. 



Macroclieiriis (ƒ . 

 Body-shape compact.' 



Anterior femora waved. 



Anterior tibiae irregularly cur- 

 ved, fringed with long hairs at 

 the under margin of the apical 

 half. 



Intermediate femora not notched 



at the end. 

 Penultimate joint of the tarsi 



broad, subcircular. 



Notes from the Leyden 



Mahakamia ,ƒ. 



Body-shape slender, wedge-sha- 

 ped. 



Anterior femora straight. 



Anterior tibiae regularly faintly 

 curved, not fringed but provi- 

 ded all along their underside 

 with rows of minute tubercles, 

 separated by a narrow well- 

 defined furrow. 



Intermediate femora with a regu- 

 larly rounded notch at the end. 



Penultimate joint of the tarsi not 

 broader than the preceding one.
