found only in the ground within a radius of 10 or 12 in. of the plants, feed- 

 ing on the fine rootlets. The exact length of the larval stage from hatching 

 to pupation has not yet been determined, although every method that could be 

 devised was" tried out. However, larvie were kept under laboratory conditions 

 for 12 days and reached an average length of 4 mm, but all died before pupat- 

 ing, while larv?e of the same average size collected in the field and placed in 

 breeding cages pupated in from 4 to 5 days, making a total of from 14 to 16 

 days, which figures are approximately the same as those obtained by Chit- 

 tenden in 1899. The transformation to pupa takes place in a simple, crude 

 pupal cell about 0.5 to 1 in. deep in the soil, the first pupa having been found 

 in the field on July 16 and the last on October 3. The average length of the 

 pupal stage was found to be 4.46 days. 



In dealing with control measures, special emphasis is laid upon three methods 

 of attack: (1) The control of the insect on the plant in the bed, (2) the con- 

 trol of the insect at transplanting time, and (3) the destruction of the suckers 

 after the crop is harvested. But little emphasis is placed upon the spraying 

 of the plants in the field, since this method will not be necessary if the other 

 methods are followed. The plant beds should be provided with a good board 

 frame and a tight beetle-proof cover of the best canvas or cheesecloth. It is 

 recommended that the plant beds be sprayed with arsenate of lead (paste) at 

 the rate of 1 lb. to 10 gal. of water, or with arsenate of lead (powdered) or 

 arsenate of lime at the rate of 1 lb. to 20 gal. of water, or the plants be dusted 

 with powdered arsenate of lead or arsenate of lime mixed with fine sifted 

 wood ashes at the rate of 1 lb. of the poison to 4 lbs. of the ashes. At trans- 

 planting time the plants should be dipped in a solution of arsenate of lead, pre- 

 pared by mixing arsenate of lead (1 lb. paste- or 0..5 lb. powder) in 5 gal. of 

 water. 



An account of this pest by Morgan has previously been noted (E. S. R., 

 23, p. 465).
