new facts of importance have come to light; nor do I find it neces- 

 sary to change my recommendations of the use of kerosene emulsion 

 and the arsenical sprays as remedies against the attacks of insects 

 upon this plant. 



Monoxia guttulata Lee. — This leaf-beetle has been sent to me from 

 the Oregon Agricultural Experiment Station by Prof. F. L. Washburn, 

 who reports it as very injurious to the Sugar Beet in the State of Ore- 

 gon. He also stated that he had found three teaspoonfuls of Paris 

 green in 4 gallons of water, in which 4 ounces of whale oil and soft soap 

 had been dissolved, to be an effective remedy without injuring the foli- 

 age. He suggests that probably the poison would have been equally 

 effective without the whale oil and soap. 



Prof. Washburn also reports that he has taken Hippodamia convergens 

 and Biabrotica vittata feeding on the leaves of the Sugar Beet in his 

 State. The latter insect has also been taken here in Nebraska during 

 the present year while feeding on leaves of both the ordinary and 

 the Sugar Beet. Biabrotica longicomis has also been collected upon 

 this plant two or three times here at Lincoln. Whether or not it feeds 

 upon the beet, I can not say at present, since the matter has not been 

 verified by actual observation. 



Cutworms. — In the early part of the season the larvae of several of 

 these insects were very plentiful upon the experimental farm here at 

 Lincoln, where/ they almost destroyed the entire crop of Sugar Beets 

 growing upon two of the plats. One noticeable fact in this connection 

 was that where there had been fall plowing and plowing again this year 

 but few of the worms were present and consequently little injury was 

 done to the beets growing on such portions of the field. 



CABBAGE INSECTS. 



Cabbage Butterflies. — These insects were not especially numerous over 

 the State during the year, but are referred to here simply because I 

 wish to call attention to a reported "new" remedy against them. To 

 say the least, it is unique as well as simple, if it proves as effectual 

 as is claimed for it. This remedy was brought to my notice about two 

 weeks ago (September 29) while at West Point, my old home, on busi- 

 ness connected with my work for the Division of Entomology. The 

 remedy is simply this: The cabbage plants are sprinkled with ordi- 

 nary corn meal while they are wet with dew or immediately after a rain 

 so the meal will cling to the leaves at all points. My informant cer- 

 tainly had nice cabbages that were free from worms, and all he had done 

 in the way of a preventive or remedy was to use this corn meal as above 

 directed or explained. He claimed that in a few days after sprinkling 

 on the meal all the worms would be found dead and turned black, cling- 

 ing to the leaves of the plants. Several cabbages that had purposely 

 been left untreated were rather full of the caterpillars of different sizes. 

 In order to test the corn-meal remedy for myself I treated these. On
