Lixus concavus Say, as an Injurious Insect. In Allegheny County, Pa., 

 the natural food-plant of this beetle is the common Burdock, the insect 

 breeding in the stem of the plant. It is indeed unfortunate that this spe- 

 cies is rapidly acquiring a decided taste for Rhubarb, upon which it already 

 depredates to a considerable extent. These beetles being of some size 

 and quite sluggish in movement may be readily picked by hand; they 

 occur from early Spring until late in Fall, being more abundant about the 

 first of June. EDWARD A. KLAGES. 



Mr. Klages' communication on the Lixus is interesting. This particular 

 species is a common eastern form, and is numerous on the Rhubarb in 

 New Jersey ; yet it rarely does any severe injury, because the growers 

 find it profitable to keep the plants trimmed up in good shape, and to 

 use up the leaves about as fast as they mature. Most of them have 

 learned, by practical experience, that it does not pay to allow them to 

 rot on the plants and therefore except in an abandoned patch here and 

 there, the leaves are generally found to be in good condition. This is not 

 an insect that need be much feared, provided reasonable care is exercised 

 in keeping down those leaves in which the larvae can develop. Although 

 the beetles are not active, yet they frequently evade capture by dropping 

 to the ground when disturbed, and when this is among grass they are not 

 easily found unless the place where they dropped is carefully noted.
