Grubs found in apple-tree.—Long-tailed Syrphus larva* from the heart 
if an apple-tree. Not naturally wood borers: inhabit stagnant water and 
rotten wood: perhaps bred in a cavity filled with water. 
Bark Lice on Lemons.—Supposed Xew Carpet J loth.—Apple Twig Primers. 
(Prairie Farmer. April 26, 1873, v. 44. p. 133.) 
A lemon infested with bark lice sent with the inquiry whether they are 
lot the apple bark louse, and if the latter may not have been introduced 
)n lemons. The resemblance is very close. A species rarely feeds on so 
liverse food plants. The apple species inhabits the trunk and branches, 
the lemon species the fruit. Scattered among the female scales are a 
lumber of male scales: this mingling of sexes does not occur in the apple 
species. The latter has multiplied most extensively in a cold climate, the 
emon species in a mild climate, and would have spread to the southern 
ipple-trees first. Hence it is scarcely possible that they are the same 
species. 
Supposed new Carpet Moth. Specimens show this to be the larva of 
Attagenus pellio. Benzine, kerosene, or a solution of red pepper would be 
effectual remedies. Dipping the infested pieces into boiling water is the 
oest remedy for the time being. 
Bostrichus bicaudatus received from Kansas, where it is working on apple 
twigs. Trim off the damaged twigs and burn them. 
Paris Green and other Remedies for Leaf-eating insects. (Prairie Farmer. May 
10, 1873, v. 44, p. 149.) 
Many of the most common and destructive insects do their damage by 
levouring the foliage of plants. The usual remedy is the application to 
the leaves of substances making the foliage either distasteful, such as 
lime,‘ashes, road dust, and whale oil soap-suds: or poisonous, as hellebore 
for the currant saw fly, and Paris green for the potato beetle. The lat¬ 
ter was probably first used successfully in 1868, by Mr. Geo. Liddle of Fair- 
play, Wis., and published in 1869. It is used mixed with dry powder or 
dissolved in water. The liquid has several advantages over the powder, 
ind may open the way to its use for other leaf-eating insects. 
Horticulture and Insects infesting Fruits and Crops.] (Proc. Warsaw Idort. 
Soc., in Warsaw [Ill.] Bulletin. June 14, 1873.) 
Out of every two hundred species of insects, one hundred and ninety- 
nine are useful or at least harmless. Examples of uses of insects given. 
The most important part insects fulfill in the economy of nature is that 
if scavengers, removing dead vegetable and animal matter. Codling 
moth and other insects discussed. Most insect ravages are committed in 
the larval state. 
The birds are man's best co-workers, and except for their efficient labors 
nsects would scourge the land. 
May Beetle or White Grub , and other Allied Species. (Prairie Farmer, dune 
21, 1873, v. 44, p. 193.) 
May beetles received which were found in ground at base of white ash 
trees nearly stripped of their leaves. This insect is one of the few which 
ire injurious in both larval and perfect states, the larva* feeding on roots 
M grasses and other plants, and the beetles eating leaves of trees. Other 
examples are found among the Chrysomelida*, where larvae and adults feed 
fide by side. Usually the adults do comparatively little harm. 
Pelidnota punctata briefly described. Eats leaves of both wild and culti¬ 
vated grapes. Sometimes abundant, but does no considerable mischief. 
Anomala varians and lucicola feed on foliage of grape, and some fruit and 
irnamental trees. In June, 1873, they appeared in Mr. Wier’s nursery, 
seriously damaging several kinds of trees, chiefly the cherry, devouring 
leaves and newly formed fruit.
