( wforhynchus qtiadridens was given its specific name by Panzer in 

 1796 (Faunae Germanics?, Heft. 36. p. 13). x 



Tie first biologic account appears to he that given by Colonel 

 Goureau in 1866 (Annales de la Societe Entomologique de France, Yol. 

 VI. p. 171). This is in connection with its development from larvae 

 living and feeding within the roots of "navette." or rape {Bra*s<ea 

 najms). 



Redtenbacher (Fauna Austriaca, Yol. II. p. 314) has mentioned its 

 occurrence on the same plant in Austria, and Bargagli (1. c. p. 264) 

 states that the beetles are found at Florence in April on the flowers of 

 CocJdearia armoracia (horse-radish), also upon cavolo (cabbage). To 

 this list Perils (Larves de Coleopteres, 1877, p. 108) adds as food plants 

 mustard (Smapis nigra) and watercress (JVasturtium officinale). 



Writing November 17, 1899, Mr. Sirrine said that he could easily 

 see how this pest might have been imported with the seed of cabbage, 

 kale, or turnips, as the adults issue on Long Island, in the neighbor- 

 hood of Jamaica, before the seed is gathered. The reason why the 

 species has not been observed in other sections of the island, however, 

 where the seed-growing industry is not followed, is not so clear, but 

 our correspondent assumes that the beetles can not obtain a foothold 

 in sections where the above plants are grown merely for marketing, 

 in spite of the fact that in most neglected fields wild radishes and 

 various wild mustards and other cruciferous plants grow which ought 

 to furnish suitable food for the beetles in all portions of the island. 



This species will be seen to differ at once from the cabbage curculio 

 by its smaller size, being about a tenth of an inch in length: by its 

 subtrapezoidal form, and by the colors of its scales. These are white 

 and intermixed with gray hairs, the whole forming a somewhat indis- 

 tinct pattern, whereas rapw, it will be remembered, is uniformly gray 

 or fulvous. The scutellar spot is prominent and the elytra are marked 

 by -trong rows of erect setae. 



CEUTORHYXCHUS CYAMPEKNIS GERM. 



What appears to be the first record of the occurrence of this species 

 in America is by the late William Juelich. in volume V of Entomo- 

 logica Americana (March, 1899, p. 57). in a note in which he refers to a 

 series of specimens taken by the writer at Ithaca. X. Y.. and to others 

 found by Dr. Otto Lugger at Baltimore. Md. The writer first observed 

 this species about 1879. but there were at that time in the collection of 

 the Cornell University a series of this weevil taken in the same region 

 in the early seventies and as near as can be remembered in 1873. 



x It was afterwards redeseribed under the same name by Gyllenhal iSchoenherr's 

 Genera et Species Curculionidum, Vol. IV, p. -"S34 1 , and later by different authors 

 under the names boraginis Gyll., ca&car Panz., paffidactylus Marsh, and quercicola 

 Marsh.
