THE CURCULIO. 



PLATE V. 



1. The Maiden's Blush Apple, Oct. 22, about half size, showing several Curculio marks, the largest in 



shape of a shield. 



2. A section of the same, cut through some of these marks, and showing no injury under the skin. 



3. An Apple, Oct. 22, greatly deformed by the punctures of the Curculio. 



4. A section of Fig. 3. The four dark lines indicate the course of the young grubs of the Curculio. 



5. An early Peach, Aug. 5. The first bite. 



6. Crawford's Late, Oct. 4th. 



THIS Plate shows the progress of the Curculio's operations upon Apples and 

 Peaches. 



Figs, i and 2 are intended to show that many of" the punctures made by the 

 Curculio upon apples do no serious injury merely leaving blemishes only skin 

 deep. These scars are of many forms, but the most common is in the shape of a 

 shield, like the largest mark in Fig. i. This shield varies greatly in size and shape. 

 If the puncture has been made on a large kind of apple very early in the season, it 

 will often expand with the growth of the fruit till it becomes two or three times the 

 size of the one in the Figure. Generally the shield-shaped mark will be wider and 

 shorter than here represented. 



In nearly all of these wounds, of whatever shape, there may be seen a little spot 

 darker colored than other parts, indicating where the egg was originally deposited. 

 More or less of these marks can be seen on most of even the best Apples in the 

 markets of New York and Philadelphia, both summer and winter, no matter from 

 what part of the country they may have come. 



Fig. 3 represents what is often called the ''gnarly" fruit. This deformity is 

 caused chiefly by the Curculio. It is very often seen in the orchard, and is espe- 

 cially common at cider mills. 



Fig. 4 is a section of the same, showing the passage-ways of the young grubs 

 towards the centre of the apple. When one of these roads is cut through the 

 centre, it will look very much as represented in this Figure ; but if the knife should
