performed with several insecticides. ;md the conclusion arrived at that 

 kerosene alone or in combination with carbon bisulphid is entirely inef- 

 ficient, but that spraying with Paris green in the proportion of f or 1 

 lb. to 20 buckets of water gives very satisfactory results. This remedy, 

 it is explained, is also effective in destroying beet fleas. 



Other insects noted as injurious to beets in this Government are the 

 larva- of Plusia gamma and of Vptys sticticalis. — P. FIREMAN. 



The pistol case bearer, V. H. Lowe (Neic York state Sta. Bui. 122, 

 pp. 221-232, Jigs. 12). — The history, name, and appearance, life history, 

 distribution, and natural enemies of this insect (Coleophora malivorella), 

 which is not to be confounded with the cigar case bearer (CJletcherella), 

 are popularly discussed and .'> experiments with remedies briefly 

 described. 



In the first experiment Paris green was used at the rate of 1 to 150; 

 in the second kerosene emulsion in the proportion of 1 to 10; and in the 

 third, trapping the moths with trap lanterns. 



The conclusions drawn are that Paris green used in the strength 

 indicated will answer for this insect: that kerosene emulsion has no 

 effect either upon the pistol case bearer or the cigar case bearer, and 

 that the trap lantern method is unsatisfactory. In appended notes the 

 reader is warned to beware of adulterated Paris green, and told how 

 to test its purity with ammonia, in which it should be entirely soluble. 

 Finally, the customary warning not to spray while the trees are in 

 bloom is given. 



A practical method of fighting cutworms in onion fields, F. A. 

 Sireine {Neic York State Sta. lint. 120,pp. 183-196, pis. 6).— The author 

 states that the principal cause of the loss of the onion crop during 

 181)5-9(; was the presence of cutworms. In Orange County in 1890, it is 

 estimated that 4G per cent of the crop was lost through this agency. 

 and in the same section in 188G the loss was 50 per cent. The bait 

 method, using dry bran or middlings, or equal parts of both mixed with 

 Paris green, is recommended as the best means of lighting the cutworm 

 in onion fields. This bait should be sown on the grass and weeds 

 along the ditches bordering the onion fields, and also in drills in the 

 fields. In the case of other garden crops, such as tomatoes, eggplants, 

 sweet potatoes, cabbages, etc., it is advised that a tablespoonful of the 

 bait be thrown about the base of each plant after it is transplanted, 

 and that where possible it be scattered over the field a few days before 

 the plants are transplanted. The history, habits, and distribution, so 

 far as known, of the insect treated (Carneades messoria) are discussed 

 and experiments with insecticides described. 



In these experiments there were tested (1) the method of spraying 

 the onion with a poisoned resin-lime mixture made of pulverized resin 

 5 lbs., fish oil or any animal oil 1 pt., concentrated lye 1 lb., and 5 gal. 

 water, and used in the proportion of 1 part of the mixture to 160 gal. 

 water; (2) spraying at night with kerosene emulsion; and (3) poisoned 

 baits. The kerosene emulsion and poisoned lime mixture were found
