as in this period they were carried down to Dehra Dun, elevation 2,10U 

 feet above sea level, their ordinary period of existence in this stage is 

 likely to be longer. Oat of fifty-one larvae and pupsB six were found 

 to harbour grubs of the Dipterous parasite noticed above. The grub

 an insect known as Sorohapok. Specimens were forwarded to the 

 Museum in the early part of February, at the instance of the Director

 a species of Chrysomelidse, genus Phadon, not previously reported in 

 connection with crops iu India, but closely related to the species Phcedon 

 betulce, Linn., which attacks the mustard plant in England. The speci- 

 mens were, therefore, sent to London to Mr, Martin Jacoby, who has 

 made a special study of Phytophagous Coleoptera. Mr. Jacoby has 

 since verv kindly examined them and reports that they belong to the 

 species FJiadon, hrassicce, Baly, also found in China and Japan.

 beyond doubt. By jarriog infested cheroots over black paper Mr, 

 Cleghorn was able to secure large quantities of eggs. Numbers of these 

 hatched out in the Museum on various dates in January, producing the 

 characteristic larva of the beetle. Mr, Cleghorn also observed the act
