In his annual report as Dominion entomologist of Canada for 1898 

 (p. 169), Dr. Fletcher briefly mentions considerable injury that was 

 done in beds of violets at Toronto, Ontario, reported to him by Mr. 

 J. Dunlop, a florist of that city. He states that complaints of this 

 false caterpillar have occasionally been noticed in the past to foliage 

 of pansies (Viola tricolor, varieties), but that no great injury had pre- 

 viously been recorded. 



Brief notice of Mr. Pratt's rearing of this species in 1899 from 

 violets received from Rhinebeck, N. Y., was recorded in the proceed- 

 ings of the Entomological Society of Washington (Vol. IV, p. 302). 



During the fall of 1899 Mr. Galloway published in his book entitled 

 " Commercial Violet Culture" a short account of this insect, without, 

 however, mentioning the species scientifically. 



The same year Dr. Fletcher again mentioned this species somewhat 

 briefly in connection with injury to pansies and violets at Toronto, 

 Canada (Transactions Royal Society of Canada, Vol. V, second series, 

 1899-1900, p. 228).

MANNER OF WORK — HABITS OF THE LARVAE. 



The larvae, while very young, feed on all parts of a leaf by cutting 

 out little holes from the lower surface, and later, when more mature, 

 eating along the edge of the leaf. Occasionally, at least, they nibble 

 the flower stalk and destroy the flower, as shown in the illustration 

 (fig. 8). An idea of their injuriousness may be had when it is said 

 that the potted plant on which the larvae were first kept began to 

 wither and die during the third week of April, necessitating the 

 removal of as many large larvae as could be found to prevent the entire 

 destruction of the plant. The second plant was injured in like man- 

 ner, and the next two or three colonies completely stripped the first
