2 Indian Insect Pests. [Vol. L 



noticed that seedling's from some experimental sowings o£ Carolina paddy 

 were attacked by the gandhi, whilst the indigenous seedlings escaped. 

 The pest was also reported from Partabgarh in Oudh, and is there described 

 as greenish-brown, having an offensive smell : it settles on the rice when 

 milky and sucks out the juice, leaving the husk dry : as many as six to 

 ten of these insects have been seeu on a single ear. The Deputy Com- 

 missioner of Hazaribagh also reports the rice-bug {Gandhi mahkhi) as 

 attacking the gora and badhi rice while in the ear : it destroys up to three- 

 fourths of the crop and generally appears in a year when the rain sets in 

 early (May). The insect in the larval state is most destructive, sucking 

 out the juices from the halm, which withers and turns yellow, but we 

 know nothing of its life-history, how many broods there are; where the 

 eggs are laid and apparently hibernate ; whether any attempts at destroy- 

 ing the pest have been made and with what result. Smoking the fields 

 attacked by burning vegetable refuse to windward might be tried, but 

 the area is too large for the ordinary methods of insecticide preparations.
