The same year Mr. James S. Hine published a very good three-page 

 account of this species, with original observations upon its life history, 

 in the Columbus Horticultural Journal (reprint, dated September 28, 

 1897, pp. 1-1). 



In the edition of the Weekly Florists' Review, of Chicago, 111., for 

 March 3, 1898, the writer published a short preliminary account of 

 this insect in answer to the inquiry of a correspondent of the Review, 

 who requested a reply through the columns of that periodical. 



Under the heading Phlyctcen ia ferrugolis Mr. Galloway mentions 

 this species on pages 211 and 215 of his work u Commercial Violet 

 Culture," published in 1899, giving a half-tone illustration of the 

 insect and its injury, from photographs of the same. 



This species was included in a list of the principal injurious insects 

 of the j^ear 1899, with brief mention of reported injury to violets in 

 Maryland and Virginia and to other greenhouse plants in New York 

 and Canada, in the Yearbook of the United States Department of 

 Agriculture for 1899 (1900), page 716. 



It has also received brief mention under the name of the chrysanthe- 

 mum leaf-skeletonizer in a paper entitled Insects Infesting Carnations, 

 by F. A. Sirrine, published in the American Florist for March 3, 1900 

 (Vol. XV, p. 912). Chrysanthemums were stated to be subject to 

 attack particularly when roses were grown in the same house. 



In Bulletin No. 60 of the University of Illinois Agricultural Experi- 

 ment Station, also published in 1900, Messrs. Forbes and Hart have a 

 short article on this species (pp. 153, r l:51), which was found attacking 

 beets at Urbana and near Pekin, 111. 



In a recent publication by Dr. James Fletcher (Transactions Royal 

 Society of Canada, Vol. V, second series, 1899-1900, p. 228) mention 

 is made of this leaf -tyer in connection with its occurrence in Canada 

 upon the leaves of roses in greenhouses. It was reported to have 

 done very serious damage three years previous to the time of publica- 

 tion, necessitating the entire cleaning out of a large house of choice 

 roses. In the same writer's report, as entomologist and botanist to 

 the Canada department of agriculture, central experiment farm, for 

 1899 (1899), pages 179, 180, and in the Report of the Entomological 

 Society of Ontario, for 1899 (1900), page 110, more detailed accounts 

 of this same attack are given, with notes. 



Mr. Davis has called this insect the celery borer, from the habit of 

 the larva of boring into celery stems; but this habit is evidently an 

 exceptional one, as it is normally a leaf-feeder, and, although its habits 

 vary, it usually joins together the leaves of the plant upon which it 

 feeds. It appears to feed b} T preference also upon the terminal leaves 

 of most plants and upon such plants as are growing in dark or pro- 

 tected situations. As the species is omnivorous and, so far as observed, 

 a pest chiefly in greenhouses, the writer some time ago proposed the
