Brief Answers to Correspondents. (Prairie Farmer. —--, 1871, v. 42, p. —.) 
Chrysomela pulchra [suturalis ]—taken with the potato beetle—has never 
been known numerous enough to be injurious. 
Insects on Apple-trees.—Assures a correspondent who finds the two- 
spotted lady-bug in his apple-trees, that this insect “feeds voraciously upon 
bark lice and stands nearly, if not quite, at the head of the catalogue of 
useful insects.” The codling moth is rarely seen except in May on win¬ 
dows near where apples have been stored, and yet probably causes more 
loss than any other insect in the world. 
Apple-tree Bark Lice.—Tells a correspondent that his failure to get rid 
of bark lice by the use of soap-suds was due to the difficulty of applying 
it to the small twigs.

The Bean Weevil. (Prairie Farmer, -, 1871, v. 42, p. -.) 
Publishes letter from Mr. Sanderson, of Pulaski Co. [Ill.], describing its 
injuries. Bruchus granarius , an imported insect, and Bruchus fabce, a native 
insect, feed on the bean. The latter is the most destructive and the one 
referred to in the letter. It is destructive locally, but not generally. Its 
peculiar mode of operation, several in i seed, riddling it with round holes, 
serve to distinguish it. Immersing seeds in hot water a few minutes be¬ 
fore planting will destroy insects in them.
