THE CANADIAN ENTOMOLOGIST. 121 



The nature of the habitat is to be indicated by the underscoring of 

 the proper words. By combination of underscores a very satisfactory 

 statement of aquatic conditions can be made. 



However, if the locality label were a general one, as "Lake Forest, 

 111.," I would suggest also a more general aquatic habitat label to go on 

 the pin, above the one just illustrated, to be marked by underscoring in 

 the same way : 



lake marsh river rapids 

 pond bog creek eddy 

 pool swale brook spring 



In a locality for which a standard detailed map is available, the great 

 exactness in locality records that is required in local ecological work may 

 be attained by indexing the map in the usual way — with letters on one 

 side and numbers on the other, and then adding to the usual general 

 locality label the letter and number from the map, to indicate the exact 

 spot from which the specimen was obtained. But, after all, from the 

 ecological standpoint, the fixing of the exact locality is of much less 

 importance than the exact indication of the sort of habitat in which the 

 specimen is found. James G. Needham, Lake Forest, 111. 



MORE CONCERNING LABELS. 



It was with interest that I read the article by Mr. Frank E. Lutz in 

 the April number of the Canadian Entomologist entitled " Labels." 



It is not so very many years ago (perhaps thirty) that we were satis- 

 fied if specimens sent to us only bore a State label, the State label as 

 first used being nothing more or less than a coloured disk, a different 

 colour for each State. A (ew years more, and we had the abbreviated 

 State label# — N. J. for New Jersey, Can. for Canada, etc. Not long 

 after, we asked our friends to mark the label in such a manner that we 

 might know from what part of the State the insect came. Then it was 

 that the collector with pen and ink would mark the label in one of the 

 corners, or perhaps make a mark in the centre, thus designating as to 

 what part of the State the insect had come from. This was not a bad 

 plan, and to-day many such labeled specimens can be seen in the " Horn 

 Collection." as well as other collections in New York and Philadelphia. 

 However, we were not yet satisfied, so some fifteen years ago our Wash- 

 ington friends started to have local labels printed with a blank space in 

 which to write the date of capture. A few years more and the collector's 

 name was called for, and this, by many, was also added. Now we have 

 the " Lutz Label " presented to us as a further advancement in the
