A specimen of this insect was cut out of its pupal chamber in the sap- 

 wood of a half-dead Odin a wodier tree by Student M. Kauli Ghosh of the 

 Imperial Forest School at Dehra, on 9 January 1902. The beetle was dead, but 

 a living larva was obtained from another gallery. This note and the insects 

 were made over to me by the student. No further specimens would seem to 

 have been taken since then.
