Life History. elegans on the Mahasu Ridge near Simla in June igoi. 



I was present with Mr. Lace at the time, and the insect 



was found to be defoliating the trees. Only the mature beetle was taken. 



On 10 May 1909 further specimens of the insect were forwarded to me 

 by Mr. T. Carr, LF.S. He found the beetle defoliating the Salix hahylonica 

 in Naini Tal. Only mature beetles were sent to me. No observations on 

 the life history of the larva appear to have been made.
