motion as soon as the alburnum is reached, and never using their 

 horns, so far as I can see, except for fighting. They breed below 

 ground, to the best of my observation. 



A neighbor says that he has been troubled with them on his 

 tobacco, to which they are extremely fatal — no plant once attacked 

 ever surviving. 



The method of feeding on the bark of the ash, as above given, is an 

 interesting item in the habits of the beetle, but it leaves us desirous 

 of further information as to whether it prefers the bark to the leaves, 

 and if it consumes, harmlessly, only the outer bark, or injuriously, 

 also, the alburnum beneath. Does the larva, in its growth within the 

 ground, subsist only on decaying vegetable matter, or in part on the 

 rootlets of the trees ? 



The nature of the attack on tobacco — in what manner and to 

 what extent it feeds upon it — would also be of much interest toward 

 a fuller knowledge of this large insect. 



Remedies. 



When attacking, to a harmful extent, shade or ornamental trees, or 

 when the offensive odor becomes intolerable, the beetles may be 

 destroyed by the application of an arsenite to the foliage, or by jarring 

 or beating them from the branches and dropping them in hot water.
