The inscription Papilio philenor, cf' , means that the specimen is a male, and the 

 inscription Papilio philenor, 9 , means that it is a female of the same species. 



The classification of the genera and species should be subordinated further to 

 the classification into families. There are five families of butterflies represented in 

 the United States and Canada. They are the following : 



1. The Nymphalidse, or "Brush-footed Butterflies." 



2. The Erycinidse, or "Metal-marks." 



3. The Lycrenidae, or "Blues," "Coppers," and "Hair-streaks." 



4. The Papilionidse, or the "Swallowtails" and their allies. 



5. The Hesperiidae, or the "Skippers." 



In every well-arranged collection of butterflies certain drawers or boxes should be 

 set apart for the reception of the insects belonging to these families, and they should 

 be placed under their proper genera, according to their species.. Nothing is more 

 beautiful or interesting to those who have a love of nature than a collection of 

 butterflies thus classified and displayed. 



In recent years an ingenious friend of mine has devised a system of mounting 

 butterflies under glass in cases made of a shell of plaster of paris, which he backs 

 with cardboard and seals around the edges with gummed paper. Latterly he has 

 taken to mounting them between pieces of glass which he secures in the same way.
