;)n the 8th of June, we visited the grounds of Mr. Bishop, and 
nd his strawberry beds badly infested—indeed, almost destroyed— 
this pest, along with a leaf-roller, to be presently described. * The 
i:er eats irregular channels through the crown, sometimes exca- 
ing large chambers, at other times merely girdling it in various 
ections, here and there eating its way to' the surface. Whether 
se chambers and channels are due to the presence of more worms 
n one in a single root, we were unable to determine with cer- 
ity. Most of the cavities contained a moderate-sized, soft, silky 
e, which, when opened, appeared nearly full of exuviae. These 
es had served as a place of retreat during winter. Most of the 
yae found at this date had eaten their way to the upper part of 
crown of the plant, just under the surface, and were found about 
center, with a hole eaten through the surface. From the fact 
t a large number of roots were examined, and although almost 
;rv one was more or less injured, but very few larvae were to be 
did, we inferred that the probabilities were that the larvae, when 
ture, usually leave the root, and undergo the change to chrysalis, 
ler under the surface of the ground or amongst rubbish at the 
face. One chrysalis only was found, and that was in the cavity 
n a root. As soon as Mr. Bishop had discovered the destructive 
SLracter of this pest, he, with commendable caution, refused to sell 
T more plants until the insect was subdued, for fear of spreading 
[, evil. He is of opinion that the insect came to him from some 
of the United States, with some plants of the Hooker straw- 
ry, as it was in a patch of these so obtained, that he first no¬ 
pal the insect working. 
Specimens of the larvae gotten late in the season wintered over, 
I I were examined on the 12th of January following, when they did 
appear so plump in body as those examined in July. They ap- 
j to spend most of the winter in a torpid state within the silken 
es before mentioned. Several were found thus sheltered at this 
e, and one, whose original abode had been disturbed in the fall, 
1 prepared for itself a similar casing within the fold of a straw- 
ry leaf. In this latter instance the larva seemed quite active, 
t ving itself briskly about whenever touched. The chrysalis of the 
3ct is very small, and of the usual dark reddish-brown color, 
it one which was found on the 8th of June produced the moth 
i, the 12th of July.” 
t'his crown miner was found by one of my assistants, Mr. W. H. 
I -man, at Normal, September 27, abundantly infesting the crowns 
vvild strawberry plants which he was searching for crown-borers 
1 other injurious insects. A number of these plants transferred 
the laboratory for observation, are still alive in good condition, 
d contain the living larvae.

Ye shall, therefore, probably be able to complete the life history 
Ihe insect next year, with respect to the particulars which remain 
unknown. 
Remedies.

1 is evident that wild and seedling plants should be destroyed 
‘-never possible, since they furnish a perfect harborage and breed-
