Imbricated Snout-beetle injuring Apple Trees. 
I mail you a little box of bugs which I found ia young apple trees; the largest ones 
ate the young growth all off.—[H. J. Lamb, Stillwater, Payne County, Oklahoma, 
June 5, 1591. 
REPLy.— * * * The beetle which is injuring the young growth of your apple 
trees is the so-called Imbricated Snout-beetle (Hpicwrus 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 in 
the proportion of 1 pound of the poison to 200 gallons of water.—[June 13, 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 the 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 (Monohammus confusor 
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 colony 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 (Zpicauta 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.—On the 25th of June, 1890, I 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. Irefer you to vol. 111, No. 4 of INsEctT LIFE, page 161, 
which gives my letter and your views on the subject in the absence of the specimen I 
sent. This insect is doing great damage in my neighborhood.—[Thomas R. Clark, 
Riverside Park, New York, N. Y., July 6, 1891. 
REpPLY.—The insect is the so-called Leopard Moth (Zeuzera pyrina) introduced from 
Europe. It has now become firmly establishedin thiscountry. In Europe it attacks 
the Linden, Soap tree, Walnut, 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 rapidly 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 pound of the poison to 50 gallons of water, just at this 
time of the year, in order to poison such larve as may be about hatching from the 
eggs and entering the twigs or trunks. Later in the season every branch which is 
observed to wilt should be pruned and burned with the contained larve.—{July 8, 
1891. ]
