 The European Lemoniid?e are included as a connecting link. The 

 narrow cross bars indicate points at which cubitus became 4-branched 

 on the fore wings ; the broad shaded bars, points at which the larva-

FOOD-HABITS OF NORTH AMERICAN 

 CERAMBYCIDiE. 



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 Lin/i. — Lives in box elder (^Negiuido 

 aceroides), oak and hackberry (^Celtis').
