200 THE CANADIAN ENTOMOLOGIST. 



ON THE FOOD-HABITS OF NORTH AMERICAN 

 RHYNCHOPHORA. 



BY WM. BEUTENMULLER, NEW YORK. 



In the present paper I have attempted to bring together all the Food- 

 Habits of North American Rhynchophora (except the Scolytidse) that 

 have been placed on record in the various entomological publications, 

 with the addition of my personal observations on the subject. 



Eiignamptus coUaris and E. aiigustatus I have found plentifully upon 

 the foliage of hickory and butternut trees. 



Rhynchites bicolor may be found on various species of wild roses. 



Pterocolus ovattis I have beaten from live oak trees at Kissimmee, 

 Florida, May, 1887. 



Attelabus bipustulatus lives on oak, rolling up the leaves (Murtfeldt, 

 Can. Ent., IV., p. 143). A. analis and A. nigripes ihoXw^ on oak. 

 The latter species I have beaten from live oak at Kissimmee, Florida, in 

 April. 



Graphorhinus vadosus feeds in the imago state on the leaves of 

 clover, according to Mr. F. M. Webster (Am. Nat., 16, p. 746). 



Epiccerus imbricatus, according to Dr. C. V. Riley, is injurious to apple 

 and cherry trees and gooseberry bushes, by gnawing the twigs and fruits ; 

 also said to be found on onions, radishes, cabbage, beans, watermelons, 

 cucumbers, beets, squashes and potato, etc. 



Exomias pellucidus. I have first taken this European beetle at 

 Astoria, L. I., in the year 1884, and again on Staten Island in 1886. In 

 Europe it lives on the strawberry. The food plant in this country has 

 not yet been detected. (See Ent. Am., III., p. 188.) 



Ophryastes vittatus is chiefly found on " greasewood," as is also O. 

 sulcirostris and 0. latirostris, according to Mr. Wickham (Ent. Am., 



v., p. 77)- 



Panscoptis eriuaceus occurs on wild grape. (Schwarz, Bull. Bklyn. 



Ent. Soc, VII., p. 84.) 



Diamimus subsericeus was taken around the roots of cottonwood by 

 Mr. Wickham (1. c, p. 78). 



Otiorhyndms sulcaUis. This European species is destructive to a 

 variety of horticultural plants. In the larval stage it attacks the straw- 

 berry, devouring the roots. O. ovatus also infests the roots of this 

 plant.
