was done until after a new flush had appeared and the bushes had been 

 well washed by rain. The Calcutta Agri.- Horticultural Society has 

 undertaken to have experiments made upon the insect with some London 

 purple that has been sent to the Museum by Messrs. Hemingway & Co., 

 of London and New York, and some of the same insecticide has been 

 furnished to Messrs. Barry & Co. for a similar purpose. The figure shows 

 some of the stages of Chlorite flaveseens y with much enlarged diagrams 

 of the antenna legs, and terminal segments of abdomen of imago. The 

 size of the insect is indicated by the hair lines 



In the crop report, for the week ending 23rd December 1891, it is 



noted that the poppy {Papaver somniferum) 

 Opium weevil. sowings in Partabgarh (North- Western Prov- 



inces) had been attacked and considerably injured by beetles. About the 



same time numerous ma- 

 ture specimens of a small 

 weevil, which is thought 

 to be the insect referred 

 to in the crop report, 

 were received from Mr. 

 J. Cockburn of Ghazipur. 

 This insect appears to be 

 a species of Sitones, but 

 as it is unnamed in the 

 Indian Museum collec- 

 tion, specimens have been 

 sent to Mens. Desbr<>cliers 

 des Loges for favour of 

 determination. In Ghazipur the insect was said to be very prevalent., 

 and an instance was quoted where fields had to be sown three times over 

 on account of the destruction caused by it to the young plants. It was 

 found only to attack the seedlings for the first four or five days of their 

 career, no damage being done after they had once attained a height of 

 half an inch. Flooding the beds was not found effectual in destroying 

 the pest, for the insects crawled on to the partition walls and thus 

 escaped drowning. Hand-picking therefore was suggested by Mr. 

 Cockburn as the most promising means of dealing with the evil. It 

 may be noticed that spraying the young plants with an arsenical insecti- 

 cide, such as London purple or Paris green, would probably be equally 

 effective and less costly than the hand-picking. The figure shows the 

 imago stage of the insect with much enlarged diagram of the antenna. 

 f lhe size of the insect is indicated by the hair line.
