APPENDIX. 



Since the present l)ulletiii has been in the printer's hands, the writer 

 has received a copy of Dr. eJames 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 {Pei'!dro)itn sauc(<t Ilbn.), 



which Avas the cause of a most remarkable outbreak in Canadti, 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 [NoctiKi c-nigruni) was also reported in Canada, and as this 

 latter species has been given more extended attention in the present 

 bulletin it may l)e well to mention some of the more important features 

 of the outl)reak. Injur}^ by this species in (^anada 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, chokecherry, and peas, but a field of oats was left 

 untouched. 



A parasite of this cutworm (Buplectr us frontal is ilow.), was reared. 



The (//'eenhome Jeaf-tyer {Pldyctimlaruhlgalis Guen.). — 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 greenJiouse Jeaf-nMer {CacoBcia imnilleJa Kob.). — During the 3'ear 

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

 its attack upon the foliage of rose bushes in greenhouses at Plamilton, 

 Ontario. Injur}^ was first noticed in June, 1899. A good account, 

 including a full description of the larva, is given. 



The cotton cutworm {Prodenia ornithogalli Gn.) — K single q^^ mass 

 from a female Prodenia eudiopta was carefully watched during March, 



1901, and it was noted that the eggs hatched on the 30th. At the end 

 of the month the larva? attained full growth, and all entered the earth 

 May 3. From these the moths began issuing ]May 28, the pupal period 

 in this instance having lasted twenty-live days. The larger propoi'tion 

 of the larvae were light in color and a small proportion were quite 

 dark. Specimens of both were isolated, and when the moths issued it 

 was found that the dark larvte all produced Prodenia eudiopta (the 

 light moth), while the light ones produced ornithogcdli (dark moth), 

 thus proving dimorphism be^^ond question. The latter name takes 

 precedence merely l)ecause the description appeared on an earlier ))age.
