fields. The egg-s are laid 

 on the ears, and the larvze 

 tunnel into the grain. 

 The second and subse- 

 quent generations are 

 spent in granaries. Each 

 caterpillar tunnels into a 

 single grain, and remains 

 concealed until just be- 

 fore it transforms into 

 a chrysalis. It then cuts 

 a small round valve-like 

 door which is pushed 

 open by the emerging

moth. The chrysalis is enveloped in a slight silken cocoon inside the 

 grain. The insect passes the winter in the caterpillar stage inside grain 

 stored in granaries. The normal number of generations in the year is 

 two, the first being spent in grain standing in the fields and the second 

 in grain stored in granaries, but further gen^erations sometimes occur 

 under favourable circumstances, A temperature of 1 04!°F., when sustained 

 for two days, is said to have been found sufficiently high to destroy this 

 insect. The Anjoumois moth therefore is essentially the inhabitant of 

 temperate regions, and is little likely to prove destructive in the plains 

 of India. (The figures show the caterpillar, chrysalis, and imago of the 

 insect, together with a maize cob attacked by it.)

great damage to paddy by cutting off the 



unripe ears from the stalks. The insects were reared in the Museum and 



in the early part of December produced moths which were found to belono* 



to the species Leucania extranea. Caterpillars of the same species were

pore, who reported that immense mischief had been done by them in 



many parts of his district. Specimens of a Cut worm probably identical 



with Leucania extranea were also received from the Manager of the Wards" 



Estate, Rungpore, who reported that the extensive injury caused by these 



insects, in cutting the paddy, had ruined many of the tenants, who had 



been impoverished by previous floods and locusts. The crops that were 



attacked were said to be nearly ready to be harvested, so that nothino- 



could be recommended for use this year. It may be noticed, however that 



the United States entomologists have recommended the destruction of 



Cut worms by strewing leaves poisoned with London purple over the 



fields, before the crop to be protected appears above the ground; while the
