This species is well distril3uted from the Atlantic to the Pacific, and 

 is found more abundantly northward. A list of localities in which it 

 is known, verified in great part by specimens in the National Museum, 

 includes the following: Buffalo, Ithaca, and New York, N. Y.; New 

 Jersey, "common throughout the State" (Smith); Pittsburg and 

 vicinity. Pa.; Washington, D. C; Tennessee; Missouri; Minnesota; 

 Wisconsin; Iowa City, Iowa; Cheyenne, and National Park, Wyo. ; 

 University, N. Dak.; American Fork Canon, and City Canon, Utah; 

 Santa Fe, N. Mex. ; Pocatello, Idaho; Montana; eastern Washington; 

 Oregon; San Francisco, San ]Mateo, San Diego, Los Angeles, Los 

 Gatos, and San Jose, Cal.; Hamilton, Ontario, Can.; Moosejaw, Assa, 

 N. W. T. ; Victoria, Vancouver' Island, North Bend, and New West- 

 minster, British Columbia. 



Hand-picking and jarring the beetles from the infested plants is all 

 that is necessary in ordinary cases of attack. When the insects occur 

 on other plants than canes bearing berries, or on roses soon to be 

 picked, they can be destroyed in the usual manner by spraying with 

 Paris green at the rate of about a pound to 150 gallons of water. 



MISCELLANEOUS INSECTS INJURIOUS TO ROSES. 



Roses have been quite subject to insect injury during the last few 

 3^ears, and some of the species which have been particularh' destruc- 

 tive or troublesome are worthy of special mention. The rose aphides 

 of the two commoner species have been abundant, and some complaint 

 has been made of the rose-chafer. 



Short notes on some interesting instances of attack follow, 



Tlie hrtstly rose worm {Cladkis pectlnicornh Fourcr.) — Numerous 

 complaints of injury reached this office throughout the month of June 

 and the early portion of July, 190(», from residents of the District of 

 Columbia. In most instances the lal•^';e were seen and all proved to be 

 this insect. Injury was also noticed l)y the writer generall}' through- 

 out the District wherever roses were grown and in neighboring por- 

 tions of Maryland. In fact the species was more trou]:>lesome this 

 year than ever before. Mrs. Flora W. Patterson, Assistant Patholo- 

 gist of this Department, who furnished larvte for identification, stated 

 that the roses most affected were La France, General flacqueminot, a 

 few pink varieties hardy to the District, and some red roses recently 

 imported from Holland. 



It w^as noticed on June jJ7 that larvK had attained full growth and 

 were rapidly disappearing from the plants. 



A rose heetle, Trichkis piger Fab. — An individual of this species 

 which is illustrated "5yTTgm^e~27, was sent to this office June 27, 1900, 

 by Mr. Ernest G. Asmus, a rose grower at West Hoboken, N. J., who 

 reported that it was doing much injury to greenhouse roses, and espe-
