the growers in that vicinity had received any young trees from Calli- 
fornia. He thinks that the insect prefers the Plum, especially the 
rapid-growing Japanese plums. They were very abundant upon 
sprouts putting out from the crowns of three hundred old peach trees 
which he topped two years before. These sprouts were covered with 
the scale, while the new tops and the old stumps were free, even when 
the sprouts had run up into the new top of the stump. AII these 
sprouts were grubbed out. 
In Mrs. Johnson’s case the statement was made that she found it 
attacking plum and peach trees in her orchard. Upon further inquiry 
it was ascertained that about four years since she purchased a small 
lot of peach and plum trees from a nurseryman in Thomasville, Ga. 
The following summer she noticed that one of the trees (a Chinese 
Blood Peach) was badly infested with the scale-insect. Some ineffec- 
tive attempts at remedial work were made, but the insect gradually 
covered the tree, and in the summer of 1891 she cut it down and burned 
it. In the meantime she had enlarged her orchard with trees from 
nurseries at Augusta and Waycross, and at about the time when she 
cut down the first peach tree she discovered that a plum tree near by 
was also affected. Since that time she has endeavored to destroy the 
scale, but at the time of writing it was present on from 25 to 30 trees. 
A later letter from Mrs. Johnson states that upon inquiry she had 
found that one of her acquaintances has had some trouble with this 
insect, and that this individual purchased the plum tree upon which it 
was first discovered from the same Thomasville (Ga.) nurseryman from 
whom Mrs. Johnson thinks she received her original stock. 
Other Species on Peach._-Mr. Henry Tryon has found in Queensland 
a species of Diaspis occurring upon Peach, which he described as 
Diaspis amygdali. He recorded it in his Report on Insects and Fun- 
gus Diseases No. 1, as occurring at Brisbane, Queensland, and Sydney, 
N.S. W., and as doing a very considerable amount of damage. This 
species has unfortunately been introduced into California, and was 
found by Mr. D. W. Coquillett in February, 1893, at Los Angeles, 
upon a dwarf flowering almond recently imported from Japan. Japan, 
therefore, may be the original home of the species, and it may have 
been imported from that country into Australia. Signoret, in the 
Annales de la Société Entomologique de France (1869, p. 437), describes 
Diaspis leperii as occurring upon Peach in Europe. The common Rose 
Seale (Diaspis [Aulacaspis| rose) also occurs sparingly upon other rosa- 
ceous plants, including the Pear. 
A Dangerous Species.—From the above facts it is evident that the 
species is a very general feeder, and, as a consequence, much more 
dangerous than if it had but one or two food-plants, as it will be all the 
more difficult to stamp it out or prevent its reintroduction. So far, it 
is true, it is reported upon but one or two food-plants in this country, 
but we shall no doubt before long hear of it upon many others, unless,
