Lpect them to be easily destroyed by any of the ordinary appli- 
litions, such as lime, ashes, or soap, provided we can find a time 
hen the substance applied will really reach them. 
The next notice of the species appears in the “Prairie Farmer” 
>r September 16, 1871, where Dr. BeBaron states that . the ob- 
irvations of the present year give us good reason to believe that 
iis little pest is not going to prove of as serious a character as 
e at first apprehended. Whether it be that they have been de¬ 
coyed by natural enemies, or, what seems more probable, m the 
bsence of any known enemies of this kind, that they aie ACiy 
usceptible to the vicissitudes of the weather, it is an ev ident 
ict that the hosts of last year have entailed a very scanty progeny 
pon the present. I visited Mr. M ier s place this season at about 
ae time of my last year’s observations, and though there were 
larks of damage by the early spring . brood, the second seemed, 
Dr some reason, to have proved abortive. I could find but few 
pecimens, and the nursery trees had made a good growth.” 
In the “Prairie Farmer” for February 10, 1872, Mr. Wier publishes 
n abstract of Dr. LeBaron’s article and gives the following addi- 
ional particulars concerning the attacks of the insect: “My 
ttention Dvas first called to it the fall of 63, by a neighboi ing 
mrseryman. * * * His acre or more of seedlings could have 
ooked no worse if they had been sprinkled over with dry straw 
nd burned over; yet, as was the case in our nursery, there was 
carcely a Tortrix to be seen the succeeding summei, and his 
eedlings made a very strong growth. I next saw it in my nursery 
n June, ’64, when it swept over a large lot of two year oid apple 
rees but did no serious damage, as there appeared to be but one 
mood. It was next seen, as stated above, about the 12th oi June, 
.870, involving the entire apple nursery here, and more or less the 
irchard. At that time the caterpillars were about half grown, but 
vere not numerous enough to do any serious damage. They com- 
nenced to change to chrysalides about the 20th of June, and. in 
Free to four clays the little bright orange moths were flitting 
iround dexiositing the eggs for another brood of worms. The eggs 
50 on hatched, and as the brood of worms was at least one hundred 
-imes more numerous than the first, the trees soon showed signs 
if damage. I did not determine positively, but I am quite certain 
:hat this brood changed to moths in about thirty days, or the 20th 
of July, and they at once laid their eggs, increasing perhaps fifty- 
fold (enemies had begun to prey upon them). They matured 
about August 20, and laid eggs for another brood about equaling 
the second; these, so far as I could see, were all killed by frost, 
that were not destroyed by their natural enemies, when about two 
thirds grown.” 
The species is next treated of in the Fourth Report of the State 
jEntomologist of Missouri (pp. 46-48, fig. 22), where the gray 
winter form is described as “The Green Apple Deaf Tyer—-Porn ix 
oinderella, n. sp;” and a short notice of Dr. LeBaron s article
