10 Beautiful Butterflies. 



extent of a Butterfly's wing may sometimes consist of 

 no fewer than one hundred thousand, seven hundred

Now let us go back to our subject, which you know 

 is Lepidopterous Insects — recollect that long word — or 

 Butterflies, we were going to say, but the thought

 lists have divided this order of insects are, as you must 

 try and remember, first, Butterflies, or Diurnal, that

 that is, Night, Lepidoptera ; and third, Hawk Moths, 

 or Crepuscular, that is, Twilight, Lepidoptera; these 

 names indicate their different seasons of flight. It is
