The Snout Butterfly, Hypatus bachniannii (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 Celtis occidentalism 
Subfamily HELICONIIN^E (Hel-i-co-ni-i'nae). 
The 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^E (Eu-plce-i'nae). 
The Euplceids {Eu-plce'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 a 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-
