to the surface. Whetliei- these various chambers and channels are due to 

 the presence of more worms than one in a single root we were unable to 

 determine with certainty. Most of the larvae found at this date had eaten 

 their way to the upper part of the crown of the plant, just under the surface, 

 and were found about the center with a hole eaten through the surface. 

 From the fact that a large number of roots were examined, and although 

 almost every one was more or less injured, but very few larvae were to be 

 found, we inferred that the probabilities were that the Urvae, when mature, 

 jsually leave the root, and undergo the change to chrysalis, either under the 

 surface of the ground, or amongst rubbish at the surface. One chrysalis only 

 was found, and that was in the cavity of a root. As s3on as Mr. Bishop had 

 discovered the destructive character of this pest, he, with commendable cau- 

 tion, refused to sell any more plants until the insect was subdued, for fear 

 of spreading the evil. He is of opinion that the insect came to him from 

 some part of the United States, with some plants of the Hooker strawberry, 

 as it was in a pitch of these, so obtained, that he first noticed the insect 

 working. 



" Specimens of the larva? gotten late in the season, wintered over, and were 

 examined on the 12th of January following, when they did not appear so 

 plump in body as those examined in July. They appear to spend most of 

 the winter in a tor^jid state within the silken cases before mentioned. Sev- 

 eral were found thus sheltered at this time, and one, whose original abode 

 had been disturbed in the fall, had prepared for itself a similar casing within 

 the fold of a strawberry leaf. In the last instance, the larva seemed quite 

 active, moving itself briskly about whenever touched. The chrysalis of this 

 insect is very small, and of the usual dark reddish brown color. That one 

 which was found on the 8th of June, produced the moth on the 12th of July." 



The moth bred from the chrysalis above mentioned was submitted by 

 Mr. Saunders to Prof. Riley, and by him determined to be Anarsia Uneatdla, 

 Zeller. Prof. Riley also says that he has bred the same moth from larvte 

 boring in peach twigs. The worm has likewise been found by Prof. Com-

stock in the fruit of the p3ach in July and August. These peach and straw- 

 b3rry insects are, however, not certainly the same, as not only their habits 

 but their life histories seem inconsistent as far as known. But, without as-
