Imbricated Snout-beetle injuring Apple Trees. 



I mail yon a little box of bugs which I foiiud ia young apple trees ; the largest ones 

 ate the young growth all off.— [H. J. Lamb, Stillwater, Payne County, Oklahoma, 

 June 5, lb91. 



Keply. — » ♦■ » The beetle which is injuring the young growth of your apple 

 trees is the so-called Imbricated Snout-beetle {Epicmus imbricatus). The breeding 

 habits of this insect are not known, but your apple trees can probably be protected 

 if the beetles are very numerous by spraying with Paris green or London purple ia 

 the proportion of 1 pound of the poison to 200 gallons of water.— [June I'.i, 1891.] 



A Longicorn Pine-borer injuring Shoes. 



We send a carton containing a bug and shoes which in our thirty years' experience 

 we "never saw the like." You will see the tissue paper and hole in tho box was 

 evidently eaten by the bug. You will also notice the destruction to the shoes it has 

 done. Please let us know what it is. — [Winch Bros. , 150-156 Federal street, Bos- 

 ton, Mass., May 17, 1891. 



Reply. — The specimen is the common Longicorn Pine-borer (jlfowo/iamm«8 confmor 

 Kirby). It has probably hatched out from the pine wood of the shoebox and find- 

 ing its way obstructed, it has tried to eat its way through, but has only succeeded 

 in getting inside the box, neither pasteboard nor kid-skin being especially suited to 

 its masticating powers. — [May 20, 1891.] 



Blister Beetles on Cabbage. 



An army of which these are specimens has possession of a large mature bed of cab- 

 bages, which they have riddled, and a footstep is enough to make them hurriedly 

 drop to the soil, which, from their numbers, ,then resembles a vast colouy on the 

 move. — [Note made at Jacksonville, Florida, May 25, 1891. C. B. Bagster, Vine- 

 land, N. J. 



Reply.— The specimens are the Three-striped Blister-beetle (fJpicauta lemniscata 

 Fab.), previously known to occur in potato fields. Cabbage is a new food-plant for 

 this species. 



The European Leopard Moth injuring Maples. 



First letter. — Ontke 25th of June, 1890, 1 wrote you for information concerning a 

 borer which has been damaging my young maple trees. I send you herewith the shell 

 of the pupa and the moth itself. I refer you to vol. m, No. 4 of Ixsec r Life, page 161, 

 which gives my letter and your views on the subject in the absence of tlie specimen I 

 sent. This insect is doing great damage in my neighborhood. — [Thomas R. Clark, 

 Riverside Park, New York, N. Y., July 6, 1891. 



Reply. — The insect is the so-called Leopard Moth {Zeuzera pyrina) introduced from 

 Europe. It has now become firmly established in this country. In Europe it attacks 

 the Linden, Soap tree, W^alnut, Elm, Apple, Pear, Mountain Ash, Chestnut, Birch, 

 Alder, and a few other trees. The moths usually issue in June, and there is probably 

 one generation annually. This insect will be a difficult one to fight if, as is so often 

 the case, it increases in numbers more rapidlj^ in America than in its native home. 

 With your young maples you are advised to spray with London purple or Paris green 

 in the proportion of one-fourth poupd of the poison to 50 gallons of water, just at this 

 time of the year, in order to poison puch larvie as may be about hatching from the 

 eggs and entering the twigs or trunks. Later in the season every branch which ia 

 observed to wilt should be pruned and buried witli the contained larvie. — [July 8,
