Tliese members will be responsible for the lists prepared by them, and such 

 lists will be published under their names. In the preparation of such lists it will 

 be necessary to seek the co-operation and assistance of other specialists and all such 

 assistance will be fully acknowledged. 



The division of the work in the different orders will be systematic rather than 

 according to the geographical regions in which the members may be located ; this 

 will necessitate the co-operation of workers in different regions. 



In the compilation of the catalogue it is intended to index the species on the 

 regular card, catalogue cards 5 in. x 3 in., which will be supplied to the members. 

 A single species will be listed on each card. The card will thus contain the infor- 

 mation which.it is intended to include in the catalogue. For example, the Spruce 

 Budworm, Tortrix fnmiferana Clemens, would be indexed and listed as follows : 



T. fumiferana Clemens.

The catalogue will be published, under the editorship of the writer, by the 

 Geological Survey of Canada, by arrangement with and the consent of the Minister 

 of Mines and the Director of the Survey. It will appear in parts as the different 

 orders, or families, in the case of large families, are completed, and its publication 

 will necessarily extend over a number of years. 



SOME NOTES ON HEPIALUS HYPEEBOEEUS. 



Horace Dawson, Htmers, P. Q. 



This season I have had splendid opportunities for watching these interesting 

 moths as not only have they been breeding all around me but some have actually 

 emerged from under my new house and some were taken inside, on windows, etc. 

 A freshly emerged female found clinging to a screen door trying to attract a mate 

 held on so tightly that the opening and closing of the door quite hard several times 

 did not disturb her. I also found, within three feet of the house, two females, just 

 emerged, the wings being not fully expanded, and give the following notes on them: 



Aug. 19th. Two fresh females found, and a glance revealed an empty but 

 evidently freshly vacated pupa-case. A further search resulted in a large number 

 of others being found, mostly older ones. Some were lying flat on the ground, but 

 the greater number were projecting about one-half of their length from perpendicular 

 silk tubes that came almost, if not quite, to the surface of the leaf mould which cov- 

 ered the ground to the depth of several inches. The moths were caged and remained
