PUBLISHED RECORDS. 



The species was first described by Boheman, in Schoenherr's 

 Genera et Species Curculionidum, volume 4, page 388, Mexico being 

 given as the habitat. The distribution of this insect, as given in 

 the Biologia Centrali- Americana, volume 4, part 4, 1902-1906, in- 

 cludes Mexico, at Cosamaloapan in Veracruz, at Jalapa, and at Teapa; 

 British Honduras, at Rio Hondo and Rio Sarstoon; and Guatamala, 

 at Chiacam and San Geronimo in Vera Paz. 



In his paper entitled "Contribution to a Knowledge of the Curcu- 

 lionidse of the United States," published in 1873, Horn gives the 

 distribution as Georgia and Florida, but mentions no food plant. 



In 1894, in Insect Life, Dr. L. O. Howard briefly reported the 

 determination of two parasites reared from CJialcodermus seneus by 

 Prof. H. A. Morgan at Baton Rouge, La. 



During the progress of some extensive jarring experiments carried 

 on in Georgia in 1901 by Messrs. Scott and Fiske this beetle occurred 

 commonly among the insects taken from peach and plum, and is so 

 recorded in Bulletin 31 of this Bureau. 



In the Yearbook of the United States Department of Agriculture 

 for 1903, Dr. F. H. Chittenden mentions the species as having been 

 reported injuring cotton in the Southern States, stating further that 

 the insect did not breed on cotton but on cowpeas. 



In February, 1904, Doctor Chittenden published in Bulletin 44, 

 this Bureau, the most extensive article that had appeared on this pest 

 up to that time. 



In September, 1904, Prof. E. Dwight Sanderson lists and briefly 

 describes it as one of the insects mistaken for the boll weevil. 



In 1905, in Bulletin 57 of this Bureau, Professor Sanderson notices 

 the insect as one injurious to cotton and, quoting Professor Newell 

 at length, gives a description of the injury done to cotton and some- 

 what of the habits of the beetles. 



Prof. Franklin Sherman, jr., in a bulletin from the North Carolina 

 Department of Agriculture, June, 1908, again lists the species as 

 injurious to cotton and briefly summarizes the knowledge from the 

 sources already mentioned. 



In a study of the breeding habits of the Rhynchophora of North 

 America, published from the University of Nebraska, Mr. W. Dwight 

 Pierce gives a very brief summary of the literature dealing with the 

 habits of the species and further states that it has once been reared 

 from a cotton square, a fact nowhere else recorded. A brief mention 

 of this same insect is made by the same author in Bulletin 73 of this
