THE CANADIAN ENTOMOLOGIST. 199 



insects bearing that label were the 400th collected during that season. 

 The sp. number is given as the insect is determined, and is the number 

 of the insect in the catalogue which we use. Thus, sp. 25 is " Cicindela 

 purpurea," as the beetle is numbered 25 in Henshaw's catalogue of 

 Coleoptera. In case the catalogue is not numbered, as is the case with 

 Cresson's list of Hymenoptera, then we number it. We have a column 

 in our accession catalogue for date, collector, person who named the speci- 

 men, and also for remarks. This last column is wide, and in it we can 

 usually write all necessary information which we received in the collecting. 

 If we are experimenting with or studying the insect, our notes are kept on 

 cards. These are numbered to agree with accession catalogue, and are 

 kept in serial order until we know the species when we add the species 

 number as well. We now index the card and place it in its correct 

 alphabetical position in our card collections. Thus we can very easily 

 find our notes on any specimen, either by accession number or by the 

 name of the species. This plan works well, and, it seems to me, is very 

 economical in respect to time. Of course our students all see this scheme 

 and become familiar with its workings. 



Dr. C. M. Weed had listened with much pleasure to the President's 

 address and approved of most of the points brought forward. He con- 

 sidered a knowledge of French and German of the utmost importance 

 from the frequent necessity of consulting works in those languages when 

 working up the life-histories of insects. He did not, however, like the 

 label submitted by Prof Cook, thinking that it entailed too great an 

 expenditure of time. He had adopted Prof. Forbes's system of labelling, 

 and had found that it answered all purposes. 



Prof. Herbert Osborn approved very highly of the course of instruc- 

 tion in entomology outlined in the address. 



Dr. C. M. Weed then read a paper upon the life-history of the even- 

 ing primrose curculio (Tyloderma foveolatum) which he had bred from 

 the stems both of Oenothera and Epilobium in large numbers. 



Prof. F. M. Webster had listened to the paper with much interest ; as 

 stated by Dr. Weed he had given some study to the insect in question, 

 and was pleased to hear these further observations. He had found that 

 when a plant was infested the beetle occurred in all its stages, and that 

 those near the base were always furtlier advanced towards maturity. 



The meeting adjourned.
