elongate. Spiracles dull orange, anterior and close to, but above tubercle iv., on abdominal 



segments. All the feet shiny brown tipped with black." (Fig 11).

spots, and of the male a Jong black stiipe, terminating in a spot near the inner margin ; these 



markings, however, are variable, in some specimens the spots are all rings and in others filled 



with black or brown. The upper portion of the body is steel blueiti colour, with — in the 



female — a lateral stripe of orange and a row of dark spots. The wings of the male expand about 



two inches and a quarter, while those of the female are fully three inchesfroin tip to tip. 



A CARD SYSTEM FOR NOTES ON INSECTS. 

 By Albert F. Winn, Westmount, Que. 



Tae myriads of curious and interesting facts, which the student of entomology is certain 

 to observe, make it necessary to have something more than the memory to rely upon. For field 

 notes a pocket memorandum book is indispensible, but for reference these notes must be tran- 

 scribed into some form in which one can classify the subjects to some extent. I have tried 

 various sorts of books, large and smiU, the mosb satisfactory having been a ledger with a page 

 or half jiage reserved for each species about which any notes were made. The index in the 

 book served to find the page of any desii'ed subject. But there were many ways in which this 

 was unsatisfactory ; the book was necessarily larg^, in many cases pages were left for species 

 on which only a few lines were used, while in others not nearly enough space was left and notes 

 had to be marked " continued page 260 " etc. Arrangement of species as to scientific order 

 was impossible, and notes on species described a^ such, which afterwards proved to be synonyms 

 were hundreds of pages apart. 



I do not know who invented the card index system but you are doubtless familar with ona 

 or more of the countless varieties of these time-saving devices, which can be adapted to almost 

 every form of business, and which are " always complete but never finished. " The standard 

 size of card used is about 3 inches by 5 and these already cut and ruled with faint lines are to 

 be had from city firms handling ofiice supplies, as can also the cards for dividing and indexing 

 the different genera, and alphabetical index. It is well to use cards that are thin, because they 

 will not take up so much space, and a great many cards will be required to keep adequate notes 

 on the subjects that we try to work up. 



I found it necessary to have three distinct parts to make the index complete — a diary, in 

 which to keep track of notes in order as to date of observation ; an alphabetical index ; and a 

 series of cards one or more for each species about which any records are made. For the diary 

 portion I begin with a colored card marked 1903 — followed by divisions for the various months, 

 parts of the cards being slightly over the 3 inches high so as to show the name above the cards
