were used more particularly in the survey work. Precautions were 

 taken to prevent the spread of spores on the part of workmen by 

 spraying the workmen at the end of working procedures with a 

 weak solution of formaldehyde. All four of these infections lay within 

 a distance of 50 miles along the St. Croix river. The last infection at 

 Pine Hollow Creek was found late in the season at the time of the first 

 frosts, so eradication of Ribes at that time was not practical. 



We believe Minnesota has a reasonable hope of eradicating the 

 disease within its borders, and to that end the legislature is being 

 pushed, and appropriation asked for from our state legislature. In 

 planning the work for next year, we are promised cooperation on the 

 part of Wisconsin authorities and it has been recommended that the 

 work in Minnesota be arranged in such a way as to give to the Plant 

 Pathologist with the cooperation of the State Forest Service, the 

 eradication of diseased or dangerous material along the St. Croix, and 

 survey and eradication in nurseries, parks and cemeteries and private 

 plantings to the State Entomologist.

NOTES ON AN INTRODUCED WEEVIL (CEUTORHYNCHUS 

 MARGIN ATUS PAYK.) 



By J. A. Hyslop, Bureau of Entomology, Washington, D. C. 



In sweepings from a mixed meadow at Bridgeport, N. Y., on the 

 southern shore of Lake Oneida, early in the spring of 1914, large num- 

 bers of a small weevil which I then took to be Rhinoncus pyrrhopus 

 Lee, were found, particularly from those parts of the field where 

 weeds predominated. Knowing that Rhinoncus pyrrhopus Hved in 

 the stems of Polygonum spp., no further attention was given to these 

 beetles. 



In May, 1916, while supervising the construction of an experimental 

 tile drainage system at the same point, the writer's attention was 

 called by Messrs. C. E. Ellis and C. D. La Rue of the State School of 

 Forestry, who were then studying the flora of the experimental plat, 

 to some small larvge feeding on the seed of dandelion (Taraxacum 

 officinale Web.). The insects proved to be the European weevil 

 Ceutorhynchus marginatus Schonh., at that time unrecorded from this 

 country. Since preparing this paper Blatchley and Leng have pub- 

 lished their monumental work on North American Rhynchophora. 

 In this work the species is first recorded from North America, being 

 taken in Massachusetts, etc., and having been reared from dandehon
