the tunnels. They attack cotton and corn, and do most damage 

 to the young plants. Large fields of cotton have been eaten in 

 a single night. They tear away the tender cotyledons and carry 

 them to their burrows, and also tear off the leaves. In badly 

 infested land from 8000 to 12,000 holes may be found to the 

 acre. The females produce from 50 to 400 eggs, according to 

 age. The ova develop in a month, and the young remain with 

 the parent for one or two weeks. They are solitary in habits. 

 A few drops of carbon bisulphide put in each hole was found 

 to kill them in a few hours. 



Chloride of lime at the rate of one ounce (of the strength 

 of one pound to three gallons of water) put in each hole also 

 kills them. They should also be killed by mechanical means. 

 Ground and mixed with meal they form an excellent egg-pro- 

 ducing food for chickens. {Vide Year-book of the Department 

 of Agriculture, U.S.A., 1911, pp. 321-324. A. K. Fisher.) 



Myriapoda. 



The myriapods are divided into two groups — namely, Centi- 

 pedes or Ghilopoda and Millepedes or Chilognatha. The former 

 have the mouth provided with foot-jaws, and have one pair 

 of jointed feet on each segment. The latter have imperforate 

 mandibles, adapted for ordinary biting and chewing. The first 

 three segments have one pair of feet on each, the remainder two 

 pairs. The feet will be seen to be terminated in a single claw. 

 Eyes may or may not be present : when present they are in the 

 form of clusters of ocelli. The jaws of the Millepedes are like 

 those of the cockroach ; but in the Centipedes the jaws are 

 formed out of the forelegs, each with a hollow tube perforating 

 the jaw, which is connected with a poison-gland on each side at 

 the base. 



The Centipedes are carnivorous in habit, and thus friends to 

 the agriculturist, whilst the Millepedes or vegetable feeders are 

 noxious. The latter are known as False-wireworm.
