FAMILY HESPERID^E. 



This family may be known by their robust bodies and 

 their triangular fore wings, and by the knob of the an- 

 tennae usually ending in an attenuated portion, that is, 

 mostly bent or hooked ; they have six feet adapted for 

 walking. In their robust bodies and coarse scales, which 

 are not closely appressed, these butterflies resemble some 

 of the higher moths. When in repose, the wings are 

 either spread or closed back to back and thrown back 

 so that the costal edge of the hind wings is next to the 

 costal edge of the fore wings. 



The family is divided into two sections, which bear to 

 each other somewhat the relation of families. 



SECTION I. 



The butterflies in this division have the knob of the 

 antenna thick ovoid or elongate ovoid. The larvae are 

 more or less spindle-shaped. The pupae are somewhat 

 conical, like those of the moths, smooth, and found in 

 puparia composed of leaves fastened together, in which 

 the larvae seclude themselves.
