FOOD-HABITS OF NORTH AMERICAN 
CERAMBYCID2E. 
By William Beutenmuller. 
In the American Entomologist, Vol. Ill, 1880, pp. 237 and 270, 
the late Dr. C. V. Riley published a paper on the food-habits of the 
long-horn beetles or wood-borers. Since then considerable has been 
added to our knowledge on the food-habits of this family of beetles. It 
has therefore been deemed advisable to republish Dr. Riley’s paper with 
such additions which have been made. For personal credit the reader 
is referred to Dr. Riley’s paper and Packard’s Fifth Report U. S. Ento¬ 
mological Commission. We are also indebted to Mr. L. H. Joutel for 
many notes incorporated in the present paper and which have not been 
published elsewhere. 
Ergates spiculatus Lee. —This western species is recorded as 
living in the roots of coniferous trees, especially pine. 
Mallodon dasystomus Say. —Bores in the wood of oak, hack- 
berry ( Celtis ) and pecan hickory, and undoubtedly other species of 
hickory. 
Mallodon melanopus Linn. —Lives in box elder ( Negundo 
aceroides), oak and hackberry (1 Celtis ).
