WITH DESCRIPTION OF A NEW GENUS AND SPECIES 



OF LONGICORN. 



BY 



C. RITSEMA Cz. 



Some days ago I received from Mr. J. D. Pasteur of Padang 

 Sidempoean (res. Tapanoeli , Western Sumatra), a few Cole- 

 optera presented to him by Mr. K. E. Keil , a military 

 surveyor of the topographical service, who captured them 

 in March of the present year in the neighbourhood of the 

 above locality , on the eastern summit of Mt. Loeboe Raja 

 at an elevation of about 2000 M. above the level of 

 the sea. 



These beetles , one of which proved to be new to science , 

 belong to the following species: 



1. Odontolabis Lacordairei Vol!. — A female of the va- 

 riety without the round orange-red spot on the front an- 

 gles of the prothorax, and with the black suture as nar- 

 row as in the male. It has a total length of 38 mm. — 

 Another, somewhat larger female specimen (41 mm.), pre- 

 sented to the Museum by Dr. Klaesi and likewise origina- 

 ting from Western Sumatra , shows faint traces of the red 

 spots on the pronotum, and a suture narrowly edged with 

 black. — A large series of males and both forms of the 

 female (typical form and variety) has been sent over by 

 Mr. J. A. N. Schagen van Leeuwen from Kotta Zuyde- 

 wijn near Solok (Western Sumatra). 



2. Aceraius emarginatus Fabr. — Two specimens. 



3. Xylotrupes Gideon Linn. — Two females. 



4. Macronota Ludekingi Voll. — Four males and three 



JN"otes from the .Leyden Museum, "Vol. XI.
