fields. The egg-s are laid 

 on the ears, and the larvae 

 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 

 twoj the first being spent in grain standing in the fields and the second 

 in grain stored in granaries, but further generations 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.) 



Cut worms. 



From the Sub- Divisional Officer of Kurigram, Rungpore, were received 

 in November 1890 Noctues larvae said to do 

 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 Leucnnia extranea. Caterpillars of the same species were 

 received in the early part of December lH90 from the Collector of Runo-- 

 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 esctranea were also received from the Manager of the Wards^ 

 Estate, Rungpore, who i-eported that the extensive in jury 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
