THE CANADIAN ENTOMOLOGIST. 203 



it is of the utmost importance that a collection as complete as possible 

 should be formed in Washington, and that it should assume a national 

 character. 



Mr. Barnard asked for some information as to the method of arrange- 

 ment adopted in the collection referred to. Prof. Comstock stated that 

 he arranged the insects in their usual order and place ; with the insect, its 

 usual food plant, and where it feeds on several or many plants, a memor- 

 andum is placed with such specimen containing a list of the plants ; by 

 this method much duplication is avoided. 



Prof. Fernald was asked to give some explanations regarding his work 

 on the Tortricidas. He began the study of this group two years ago, 

 commencing with those species found in Maine, but soon found that he 

 could do nothing satisfactorily without taking in all those found through- 

 out the United States and Canada. He has also found it necessary to 

 study the European forms, and is now engaged in examining all these 

 structurally, with the view, if possible, of improving their classification, and 

 earnestly desires help from collectors in all parts of the country, especially 

 in reference to the larva? of the different species. He thinks that the 

 character of the head, thoracic shield and anal plate will probably be of 

 most value in separating the species. 



Mr. Saunders reported that Papilio cresphontes had been found rather 

 common both in the larval and perfect state in several parts of Ontario 

 this season. Dr. Morris said that he had found Papilio ajax particularly 

 local in its distribution, abounding in some localities, but very scarce in 

 others. 



Mr. Lintner stated that Pholisora catallus had not been found about 

 Albany until three years ago, when a single specimen was taken ; this 

 year it is one of the commonest species in and about the city ; its food 

 plant is Monarda punctata. 



Rev. C. J. S. Bethune referred to the great abundance of Papilio 

 philenor one season many years ago in the neighborhood of Hamilton, 

 Ontario ; since then he was not aware that it had ever been found com 

 mon in any part of Ontario. 



A question was asked by Mr. Grote as to whether any of the species 

 of Cucullia ever come to sugar. In reply, Dr. Bailey stated that he had 

 captured three species of Cucullia and ten species of Plusia at sugar. 

 Recently, when sugaring in a certain locality, he was surprised to find a
