APPENDIX. 



Since the present bulletin has been in the printer's hands, the writer 

 has received a copy of Dr. James Fletcher's report as entomologist and 

 botanist of the Experimental Farms of the Dominion of Canada" for 

 1900, in which several of the species here treated are considered. 



One of these is the variegated cutworm {Peridroma saucia Hbn.), 

 which was the cause of a most remarkable outbreak in Canada, includ- 

 ing British Columbia. This matter will be referred to somewhat more 

 at length in a future publication on that species. 



A somewhat similar but less formidable outbreak of the spotted 

 cutworm {Noctua c-nigrwrri) was also reported in Canada, and as this 

 latter species has been given more extended attention in the present 

 bulletin it may be well to mention some of the more important features 

 of the outbreak. Injury by this species in Canada was reported from 

 Niagara and in several places north of Lake Ontario. It was also 

 abundant at Ottawa. Almost all kinds of vegetation, with the excep- 

 tion of various grasses, were attacked, the larval habits assumed in 

 this case resembling very closely those of the variegated cutworm. 

 At Whitby the fruit of tomatoes were devoured, the cutworms eating- 

 through the skin and consuming the inside. Oats, peas, and cauli- 

 flower were also attacked. At Georgiana these cutworms stripped a 

 field of carrots and mangels, devoured the leaves of Canada thistle, 

 gooseberry, chokeeherry, and peas, but a field of oats was left 

 untouched. 



A parasite of this cutworm {Euplectrus frontal is How.), was reared. 



The greenhouse leaf-tyer (Phlyctmnia ruhigcHis Ghien.). — A detailed 

 description of the larva of this species and its manner of working is 

 given with reference to injury to roses, violets, and chrysanthemums 

 at Toronto the previous year. 



The greenhouse leaf-roller ( Gacoecia parallda Rob.). — During the year 

 1900 this species came under notice for the first time in Canada, from 

 its attack upon the foliage of rose bushes in greenhouses at Hamilton. 

 Ontario. Injury was first noticed in June, 1899. A good account, 

 including a full description of the larva, is given.
