experiments prove, I think, that the hind legs assist in dragging 

 the body backward. A microscopic examination of the legs 

 reveals two terminal claws which function in this work (Fig. 12). 



EMERGENCE OF THE IMAGO. 



This section does not pretend to be a life history of the ant-lion. 

 That the author hopes to make the subject of a future paper. 

 This is simply an attempt to state some interesting facts about 

 the last stages of the metamorphosis. 



At the close of its larval period, the ant-lion constructs a 

 subterranean spherical cocoon of silk and soil. In my insectary, 

 most of the cocoons have been formed quite near the surface; 

 sometimes projecting slightly above the soil. In one case, 

 however, I found a cocoon on the bottom of the jelly glass,

fully two inches below the surface. In my insectary, the cocoons 

 have been formed in July and in August and the imagoes have 

 emerged in from 9-20 days thereafter; but I do not consider that 

 I have sufficient data to warrant the statement that they are 

 always formed at those times. 



Inside of this cocoon the insect sheds its last larval skin and 

 becomes a chrysalis. At the end of a certain period of time the 

 anterior portion of the thorax protrudes from the cocoon (Fig. 7). 



All of the accounts that I have read state that the chrysalis 

 comes about half way out of the cocoon and from its dorsal
