22 ZOOLOGY 



orange band and white spots running obliquely across 

 the upper side of the fore wing. It occurs in England 

 as well as in the United States. Here belongs also the 

 Viceroy, which is not closely related, but is quite similar 

 to the Monarch because the former mimics the latter. 

 They are both of a tawny orange color, with a white- 

 spotted black border on the outer wing margin. The 

 Monarch is the larger, and like the birds has the habit 

 of migrating southward in the fall and returning in the 

 spring. The Fritillaries (Argynnis 1 ) include some large 

 butterflies, having numerous round and triangular silvery 

 spots on the under side of the hind wing. 



To the Lycaenas 2 belong the Blues, or Spring Azures, 

 including small satin or steel-blue species which exhibit 

 marked seasonable polymorphism ; the Coppers, orange- 

 red, or brown species; and the Hairstreaks, or Theclas, 3 

 which are small, brown butterflies, usually with two tails 

 to the hind wing. 



Types of the Moths. - These include all Lepidoptera, 

 excepting the family of Papilionidse. Seven families are 

 of rather large size (Macrolepidoptera) ; the remaining four 

 are of small size (Microlepidoptera).
