gists of the country during the past 2 years. A map is given showing 

 the known distribution of the San Jose scale, accompanied by notes on 

 its present condition in the following States: Alabama, Arkansas, Ari- 

 zona, California. Connecticut, Delaware, District of Columbia, Florida, 

 Georgia, Idaho, Illinois, Indiana, Kentucky, Louisiana, Maryland, 

 Massachusetts, Michigan, Minnesota, Mississippi, Missouri, Nevada, 

 New Jersey, New Mexico, New York, North Carolina, Ohio, Oregon, 

 Pennsylvania, South Carolina, Tennessee, Texas, Virginia, Washington, 

 West Virginia, and Canada. 



Seventeen new food plants have been listed. They are as follows: 



" Orchard fruits.— Pear, peach, apple, plum, cherry, Kocky Mountain dwarf cherry, 

 persimmon, quince, flowering quince. Small fruit*. — Strawberry. Bush fruits. — 

 Raspberry, gooseberry, grape, curraut, flowering currant, black currant. Nut 

 plants.— Almond, chestnut, pecan, black walnut, English walnut, Japan walnut. 

 Ornamental plants, forest, and shade trees. — Rose, hawthorn, spiren, cotoneaster, euony- 

 mus, English huckleberry, linden, acacia, elm, osage orange, alder, sumac, weeping 

 willow, English willow, golden willow, laurel-leaved willow, milkweed, catalpa 

 speciosa, Lombardy poplar, Carolina poplar, golden-leaved poplar, silver maple, 

 cut-leaved birch, mountain ash, Japanese quince, actinidia, Citrus trifoliata, red 

 dogwood, snowball, Juneberry, loquat, laurel, and akebia.'' 



The difference between the San Jose scale and 2 closely allied spe- 

 cies, the Putnam scale (Aspidiotus aneylus) and the Forbes scale (A.for- 

 besi) are pointed out. The relation of climate to the spread of the 

 insect is briefly discussed. 



In regard to natural enemies of the scale, the author says that in 

 no case since the publication of the former bulletin have any insect ene- 

 mies been reported as doing any good. Specimens of Australian lady- 

 birds were distributed in New Jersey and at Y\ ashingtou, but no results 

 have been obtained from them. The identification and study of a 

 parasitic fungus (Sphwrostilbe coccophila) by the Florida Station (F. S. 

 R., 9, p. 1008) and work with it in New Jersey and elsewhere is noted. 



In regard to remedies the work of the Virginia Station with the gas 

 treatment and with pure kerosene (E. S. E., 9, pp. 672, 10(57) is reviewed, 

 as is also the work with kerosene at the Georgia, Ohio, and New Jersey 

 Stations (E. S. E., 9, p. 1066; 10, p. 161). 



In experiments of the Division of Entomology, peach, pear, cherry, 

 and apple trees sprayed with pure kerosene while their buds were dor- 

 mant were uninjured. On some of the trees 99 per cent of the scales 

 were killed by the kerosene. Cases are noted, however, in which 

 orchards sprayed with kerosene were very seriously injured. There- 

 fore the author recommends the use of kerosene on a small scale at 

 first to determine whether it can be advantageously used in different 

 localities. 



Recent legislation in regard to the San Jose scale is briefly noted, 

 and the German edict in relation to the importation of plants and 

 fruits from America is given. 



A bibliography is given including publications during L896 and 189* 

 and omissions from the previous bibliography.
