could be employed during the winter season, owing to the injury it would 

 occasion to the foliage and blossoms or fruit. For the purpose of ascer- 

 taining how strong a wash could be used on various kinds of deciduous 

 fruit trees during the summer season, I made, a series of experiments 

 with resin washes of various strengths on the 4th of September of the 

 present year. I used a wash two-fifths and also one three-fifths as 

 strong as in the formula given above j these I sprayed upon apple, 

 pear, peach, and prune trees a short time before the noon hour, and at 

 a time when the sun was shining brightly, but none of the leaves on 

 any of these trees were injured even by the strongest wash. Only the 

 apple trees contained any fruit, but this was not injured by the wash. 

 The stronger wash is of the same strength as that commonly used for 

 the destruction of various kinds of scale-insects upon citrus trees in 

 the hottest part of the summer season, and the above experiments in- 

 dicate that it can also be safely used upon growing deciduous trees. 



I also sprayed some of the stronger wash upon a rose bush, but the 

 leaves on this bush were slightly injured by it; on these bushes, there- 

 fore, it would be necessary to use a somewhat weaker wash. 



The Greedy Scale. 

 (Aspidiotus rap ax Comst.) 



This scale-insect received its name not from a voracious nature and 

 consequent destructiveness, but rather from the fact that it infests such 

 a great variety of different kinds of trees and plants. The following is 

 a list of those upon which I have found full-grown specimens of this 

 species : 



Apple, Pear, Loquat, Myosporum, Birch, English Laurel, Maple, Sil- 

 vertree from South Africa (Leucadendron argenteum), Bhamnus croceus, 

 California Walnut (Juglans calij vrnicus), English Holly, Fuchsia, Cot- 

 tonwood, Camellias from Japan, also on oranges and lemons. 



The last two fruits sometimes become very thickly infested with these 

 scales, but this seldom happens, except in the case of those allowed to 

 remain on the trees for several months after they are ripe ; in such 

 cases I have never found one of these scales upon any other portion of 

 the tree. 



This insect was evidently imported into this State from some other 

 country, although I can not find any reference to it in foreign countries 

 in any work to which I have access. It is possible, however, that this 

 is the same insect previously described by Boisduval under the name 

 of Kermes camellice, and which has been referred to the genus Aspidiotus 

 by later authors. This latter species also infests Camellias, Euonymus, 

 and various other kinds of ornamental shrubs and trees in Europe, New 

 Zealand^ and perhaps also in other countries.
