ferfly sucks up the nectar from flowers or drinks water from moist places (see 

 Plate A, Figs, c and d). We have not the space in this little manual to go more 

 deeply into the anatomy of these organs, but enough has been said to enable the 

 beginner to recognize the various parts. The student realizes that the head in 

 general supports the principal organs of sense and the proboscis, or mouth. 



The thorax carries the organs of locomotion, which consist of four wings and 

 six feet. The thorax is made up of three segments, or rings, the foremost of which 

 is called the prothorax, the next the mesothorax, and the hindmost the metathorax. 

 The subdivisions of the thorax are not easily distinguishable by examining the 

 body of a butterfly even under a microscope, because the bodies of butterflies are 

 generally heavily clothed with hairs and scales. In order to clearly make out the 

 subdivisions, which we are considering, it is necessary to take a specimen and de- 

 nude it of its scales and hairs, and even dissect it under a glass. The correctness 

 of the foregoing statements then becomes apparent. 



The legs of butterflies are arranged in three pairs, the foremost of which are 

 known as prothoracic, being attached to the prothorax; the second pair are called 

 mesothoracic, springing, as they do, from the middle segment of the thorax; and the 

 last are styled metathoracic legs, rising from the hindmost segment of the chest 

 (see Plate A, Fig. c). It should be noted here that in the great family of the Nym- 

 phalidce, or "Brush-footed Butterflies," in both sexes the anterior, or prothoracio
