LIBYTHEA FABRICIUS (TnE SNOUT-BUTTERFLIES) 



Small butterflies, the palpi enormously produced in compari- 

 son with other butterflies. The fore wings are strongly ex- 

 cavated on the outer margin, and produced at the end of the 

 lower radial. The hind wing is upwardly lobed at the base, 

 excised before the outer angle, and the outer margin is some- 

 what scalloped. The egg is ovoid, nearly twice as high as wide, 

 ribbed, every other rib'being higher than the one beside it and 

 increasing in height toward the top. The caterpillar has a 

 small head, overarched by the anterior swollen segments; it 

 lives upon the hackberry (Celtis). The chrysalis has the ab- 

 domen conical, the head pointed, with two raised ridges run- 

 ning from the head on either side to the middle of the first 

 segment of the abdomen; between these ridges is a low tubercle. 



There are numerous species found in all parts of the world, 

 but only three occur within our limits. Of these we figure the 

 one which is most widely distributed.
