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

 is found more abundantly in the northwest. 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 Jerse^v, "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. The insect can be 

 destroyed by spraying with Paris green at the rate of about a pound 

 to 150 gallons of water, except when it occurs on plants bearing berries, 

 or on roses soon to be picked. 



MISCELLANEOUS INSECTS INJURIOUS TO ROSES. 



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

 years, and some of the species which have been particularly 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 hristl/y rose worm {^CUadms pecthiicornis Fourcr.) — Numerous 

 complaints of injury reached this office throughout the month of June 

 and the earl}' portion of July, 1900, from residents of the District of 

 Columbia. In most instances the larva? were seen and all proved to be 

 this insect. Injury was also noticed by the writer generall}^ through- 

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

 tions of Maryland. In fact the species was more troublesome this 

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

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

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

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

 imported from Holland. 



It was noticed on June 27 that larvie had attained full growth and 

 were rapidly disappearing from the plants. 



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

 which is illustrated by figure 27, was sent to this oflice 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-
