40 LEPIDOPTERA. 



double tailed. The larvae are slug-like, as when mov- 

 ing on their short feet, sixteen in number, they seem 

 rather to glide than walk. They are oval, flat below 

 and rounded above, both extremities being much alike, 

 with the small head retracted within the body. The 

 short and thick chrysalides are flat beneath, but very 

 convex above and rounded at each end." (i, 264). 



"The Hesperians, or Skippers, are a large group of 

 small, dark dun-colored butterflies, whose antenna; 

 have the knob curved like a hook, or ending in a little 

 point bent to one side, reminding us of the antenna; 

 of the Sphinges. They are moth-like in their mo- 

 tions, form, and larval characters. They are stout 

 bodied, with large heads and prominent eyes, and 

 thick palpi, almost square at the end. The larvie arc 

 spind'le-shaped, naked, and with a remarkably large 

 head. They are solitary, and often hide in folded 

 leaves like the Tortricidce, transforming in a rude co- 

 coon of dead leaves or stubble, held together by silk- 

 en threads. The pupa; are somewhat conical, like 

 those of moths, smooth and generally covered with a 

 bluish white powder. They are fastened by the tail 

 and a slight band of threads within their rude co- 

 coons. We have many species in this country."

Sphingid/E {Haii'k-moths or Humming-bird moths). 



These moths may be easily recognized by the form 

 of the body, wings and antennjE. The body is very 

 stout, spindle shaped ; wings long, narrow, and very 

 strong; antennae prismatic in form, and more or less 

 thickened in the middle or toward the tip, which ii fre- 

 quently recurved in form of a hook. The sucking tube
