Answers to Correspondents. [We hope to make this one of the most interesting and in- striiLtive departments of tlie Entomologist. All inquiries about insects, injurious or otherwise, should be accompanied by specimens, the more the better. Such specimens, if dead, should be packed in some soft material, as cotton or wool, and inclosed in some stout tin or wooden box. They will come by mail for one cent per ounce. should never be ENCLOSED LOOSE IN THE LETTER. Whenever possible, larvae (/. e., grubs, caterpillars, maggots, etc.) should be packed alive, in some tight tin —the tighter the better, as air-holes are not needed—along with a supply of their appropriate food sufficient to last them on their journey ; otherwise they generally die on the road and shrivel up. If dead when sent, they should be packed in cotton moistened with alcohol. Send as full an account as possible of the habits of the insect respecting which you desire information ; for example, what plant or plants it infests ; whether it destroys the leaves, the buds, the twigs, or the stem ; how long it has been known to you ; what amount of damage it has done, etc. Such particulars are often not only of high scientific interest but of great practical importance.] Worm infesting Meal Sacks.—Will you please give me the name
