Cards for Data. 



BY SIDNEY C. CARPENTER. 



I was much interested in your editorial on pp. 25 and 26 of 

 the January NEWS in regard to modern aids in the work of 

 entomologists. I enclose a sample of three cards that I am 

 using, which may be of interest to some of your readers. In 

 all three forms the name of the species is entered on the red 

 line at the top. 



Of course the requirements of no two collectors would be 

 just alike, but special cards will be printed very cheaply by 

 any manufacturer of card index supplies, and the first cost of 

 a cabinet, which need not contain more than one or two draw- 

 ers to start with, will be more than offset by the time and 

 labor saved in keeping and referring to records. 



I use Form i for each specimen in the mounted collection. 

 The space at the right is for the date of the different stages, if 

 the specimen has been bred. "Jo. No." is the Journal Num- 

 ber which I give to each set of eggs, caterpillars, etc., to 

 enable me to keep track of their records.
