 Amongst the inquiries relating to other Orders of Insects 

 the most important was one received from the Government of 

 Mauritius, through the Director of the Imperial Institute. 

 This had reference to the great destruction of the roots of 

 sugar-canes in Mauritius by innumerable grubs of a species of 

 beetle of the cockchafer family, believed to have been recently 

 imported into the island. From specimens forwarded for 

 determination, this species (Phytalus smi^Ai, Arrow) was found 

 to be a native of the West Indies till then unnamed. 



These facts and advice as to the steps for dealing with the 

 pest were communicated to the Government of Mauritius.

 information and advice have been sought, and as far as possible
