LEPIDOPTERA. 397 



The Snout Butterfly, Hypatus bachmannii (Hyp'a-tus 

 bach-man'ni-i). The wings are blackish brown above, 

 marked with orange patches and white spots. The species 

 occurs throughout the Eastern United States, excepting the 

 northern part of New England and the southern part of 

 Florida. The larva feeds on Ccltis occidentalism 



Subfamily HELICONIIN^E (Hel-i-co-ni-i'nae). 

 TJie Heliconians (Hel-i-co'ni-ans). 



This subfamily consists chiefly of tropical butterflies ; a 

 few species, however, extend into the southern portion of 

 our territory. They are of medium or rather large size, 

 and are easily recognized by their narrow and elongated fore 

 wings, which are usually more than twice as long as broad. 



Subfamily EUPLCEIN^; (Eu-plce-i'nae). 

 The Euplceids (Eu-plcc' ids). 



These are butterflies of large size, with rounded and 

 somewhat elongated wings, the apical portion of the fore 

 wings being much produced. The absence of scales on the 

 antennae is the most available character for distinguishing 

 these insects. Only a very few species occur in our fauna* 

 The best known of these is the following : 



The Monarch, Anosia plexippus (A-no'si-a plex-ip'pus). 

 The upper surface of the wings is light tawny brown, with 

 the borders and veins black, and with two rows of white 

 spots on the costal and outer borders as shown in Figure 

 469. The figure represents a female ; in the male the veins 

 of the wings are more narrowly margined with black, and 

 there is a black pouch next to vein VII 2 of the hind wings, 

 containing scent-scales or androconia. 



The larva feeds upon different species of milk-weed, As- 

 clepias. When full grown it is lemon or greenish yellow, 

 broadly banded with shining black. It is remarkable for 

 bearing a pair of long fleshy filaments on the second thoracic 

 segment, and a similar pair on the seventh abdominal seg-
