from the localities in which he found it abundant stock was imported into 

 this orchard on the Delaware. Judging from the number of specimens 

 found, and from the territory which this insect seems to have covered, it 

 is reasonably certain that it has been in its present location at least two 

 years, and quite enough specimens were observed to make it probable 

 that next year, under ordinary circumstances, a considerable spread from 

 this orchard will take place. Fortunately, the owners of the orchard in 

 question are intelligent men, and men who realize the importance of 

 dealing promptly in matters of this kind. They have therefore agreed to 

 take active measures, recommended by me, during the ensuing Winter 

 and early next Spring, and there is reasonable hope that it will be possible 

 to check the further spread of the insect, and to reduce its numbers to 

 such an extent, that we may reasonably hope that the survivors will fall 

 victims to natural causes. We are not unreasonable in expecting the 

 latter, because heretofore the insect seems not to have shown any ten- 

 dency to migrate in the direction of the location where it has just been 

 found. It behooves fruit growers and farmers generally who purchase 

 plants, trees, grafts, or the like, from any locality other than their own, 

 to make a most careful examination of the plants before they set them 

 out, to make sure that no insects are introduced with them. It is care- 

 lessness in this respect that has given us some of our most troublesome 

 insects, and it has been the almost universal experience that where an 

 insect was introduced and showed itself capable of multiplying that such 

 species become the most difficult to deal with. 



A "Rose Bug" Remedy. In the 5th Report of the Board of Managers 

 of the Rhode Island College, we find in the Report of the horticulturist: 

 "A Remedy for the ' Rose Bug.' ' This remedy is nothing except a 

 thorough spraying with the Bordeaux mixture, to which Paris-green was 

 added in considerable quantities. This, it seems, rendered the vines un- 

 pleasant to the " rose bugs" and they ceased feeding upon them. Reports 

 of this kind have been made before, and I do not for an instant question 

 their accuracy, but there are as many cases equally authentic where the 

 remedy has proved no remedy at all. I have myself seen "rose bugs" 

 feeding upon foliage and buds that were completely covered with the 

 Bordeaux mixture, and it did not even seem to disagree with them. It 

 only emphasizes what has been already stated elsewhere concerning this 

 insect, that when it appears in reasonable numbers it is not difficult to 

 keep it from grape, and a dusting with lime, or in fact a considerable 

 number of other substances, will prove reasonably effective. It is when 

 they appear in such enormous swarms that everything is covered with 

 them, that all remedies fail as completely as do all signs of rain in times 

 of drought. Then, apparently, they will eat everything that is in the way, 

 and it makes no difference what poison is used. 



Notes on some Ptinid Pests. Insects injurious to vegetation do not al- 

 ways confine their attacks to growing plants; but sometimes cause con-
