TIr* roiinnon met hod of j)iocetliiie a«j:aiii.st this insect, aiul tlie one 
liitherto ^t'lierally siij^'^ested, is to clij) oft' and burn the witliering 
infested tips in the sprinj,^ as soon as the injury is noted. Tlie fore- 
going life history emphasizes the fact that it is necessary to do this 
very promptly, for the larva* remain in these situations a very short 
time, and early in ]May tlie larva* will ha\e abandoned tiieir l)nrro\vs 
in the youn«^ shoots to transform, often elsewhere, althou<;h sonietimes 
]>npatin«;' in the withered leaves. Tiie presence of dyin^ terminals 
does not always indicate that a larsa is necessarily piesent, since in 
many instances it will have wandered to some other point. With large 
orchards this step would be a very tedious one and with trees of any 
size often impracticable. 
The knowledge of the hibernating habits of this insect indicates a 
more ettective method of control, namely, the one already recommended 
by Mr. Craw on the strength of Mr. r^hrhoriTs observations. This is 
in si)raying the trees during January or February with kerosene emul- 
sion <u- resin wash, or some similar oily preparation, which will i»ene- 
trate the burrows and destroy the young larva*. 
It is i^ossible that something could be accomi)lished by an arsenical 
si)ray in the fall, but si)ecial care would have to betaken to get it where 
the eggs are ai)t to be i)laced. Many of the larva* might thus be 
l)oisoned while eating through the bark preliminary to the construction 
of their hibernating burrows. To eftect anything by this course the 
poison must be applied early — that is, before the eggs are dei)o8ited — 
and its feasibility will depend somewhat on the conditions of the trees 
and the danger of scalding foliage. 
In the matter of spraying with i)()isons for this insect a timely sug- 
gestion is made by Mr. Cordley, viz., to spray the trees with paris 
green just when the leaf buds are unfolding, so that the first meal 
taken by the larva* in the spring will be a poisonous one. In spraying 
the young tender foliage of the peach, plum, etc., a strength should be 
used not greater than one pound of the poison with an equal amount of 
lime ill 200 gallons of water. 
mBLIOGRAPHY OF THE PRINCIPAI. WRITINGS. 
The following bibliography of this insect gives the i)rinci])al writings 
but omits a number of unimportant references which merely repeat the 
common information relative to the species. Some of the articles cited, 
as will be duly indicated, relate in i)art at least to a distinct insect, viz, 
the strawberry crown-miner, which seems to be undescribed. 
Zeller, C. p.— Isis, 1839, p. 100. 
Contains tlw original description of the moth. 
Clemens, Dr. B.— Proc. Acad. Nat. Sci.. Phila., 18()0. p. IGO. 
Describes the insect as Amtrsia pniinclla from an adult reared from a hirva 
taken crawling on a plum tree.
