 belong to the butterfly and differ widely from any 

 feature in the caterpillar ; the wings, therefore, 

 naturally occupy the larger space, 

 their tips meeting or nearly meet- 

 ing in the middle line of the belly ; 

 next their upper edge lie the anten-

 the legs, while down the middle, 

 between these, lie the two parts of 

 the maxillae or tongue. As, how-

 at the femoro-tibial articulation, so that only the 

 tibiae and tarsi of any of the legs are exposed ; 

 then that the hind tibiae and tarsi are concealed 

 beneath the wings, just as they are in a large 

 number of pupae of beetles or other insects, where 

 they can easily be seen because they are not con- 

 solidated with the body ; the parts, therefore,
