during the day. I have had many letters with specimens of this, 

 sent for information. Last fall, just at twilight, I discovered a 

 New York curculio at her work. I watched her till she had com- 

 pletely girdled the terminal shoot of a young apple tree. 



In this connection I will call your attention to the plum curculio. 

 There are many species of curculio, all more or less injurious, but 

 this rascal bears off the palm. There were none at Racine previous 

 to 1856. 



JBupestris femorata. This works not a little injury to the apple. 

 The Bupestrida? are borers, but they always select a spot where 

 the bark is slightly loose, in the crevices of which they deposit 

 their eggs. The young, when hatched, soon penetrate the wood 

 and live there during their larval state. Apple trees are so weak- 

 ened by their perforations, that they soon yield to the wind. If the 

 decay hastened by these insects does not prove fatal to the tree it 

 affords a happy hunting ground where hundreds of Bupestrida? join 

 forces. Union is strength, but not for the poor tree, which soon 

 succumbs to numbers. Many apple trees are lost, the owner hav- 

 ing no idea of the cause. A little Paris green might save the trees 

 if properly used. 



The gray Xylina, Xijlina cincra^ appears to be a general feeder. 

 It is frequently found on the apple tree according to Riley, who 

 first described the abundant western species. It not frequently 

 bores into the fruit; apple, plum, peach, etc. The larva? may be 

 known by a narrow dorsal and a wide lateral colored stripe, color 

 shining green. This species may prove decidedly injurious to 

 Wisconsin. 



The Dagger moth, acronyctia. The larva? may readily be known 

 by their long, soft, light colored hairs that project directly from the 

 body, and about five long, black pointed tufts which project out- 

 wards, somewhat like daggers — hence the name. The species 

 which I bring is the acronyctia superans. I have repeatedly taken 

 this species in orchards, and I am not without suspicion that the 

 larva? feed on the apple. 



Foes of Grape. 



Eudryas grata and unio. Two species of wood-nymphs and 

 the spotted forester, Alypia octomaculata, feed upon the grape,
