Walker asserts that this species is from Silhet ; but there is no locality given for it in 

 the register. It was presented to the collection by Mr. Doubleday along with many other 

 species, most of them without localities. It is a well-marked species, and perfectly dis- 

 tinct from P. castor. The type in Mr. Moore's collection comes from Simla, North-west 

 Himalayas, 7000 feet ; it was taken by Capt. Lang.
