from an inch to an inch and three-quarters in length, are 

 thick and whitish, and they form a pod-like chrysalis, sim- 

 ilar to that of the Peach Tree Borer, but within or beside 

 the injured roots. 



The moths are of a dark brown color, tinged with taw- 

 ny-orange, and banded with bright yellow on the edge 

 of the second ring of the body ; the fore-wings are dusky,

Remedies. — No effectual methods of prevention are 

 known ; but it is well to inspect the vines, and when the 

 presence of the insects is suspected, examine the roots, 

 to find and destroy the worms. 



NETJEOFTESA, HYMEKOFTERA, AND BIFTEBA. 



These several orders will be introduced together for 

 convenience, as they may be disposed of in a briefer 

 mention than some of their predecessors ; because th^y do 

 not contain so many species that are noxious by preying 

 upon our cultivated plants. Some are even of advantage 

 to us by their carnivorous propensities. 



Among the Nenroptera are several which are aquatic in 

 their larval condition, but when winged, they devour 

 many insects ; among these are the Dragon-flies, common- 

 ly called Devil's-needles by the children, who dread them, 

 but they are harmless creatures. The Ant-lions were re- 

 ferred to xmder the head of Apliids, in the consideration 

 of the order Hemiptera, as most voracious destroyers of 

 Plant-lice. Reference was also made to the Lace-wmged 

 Flies, Semerobim, which, in the larval state, consume
