Postscript, added 10th September, 1919: Since the above was 

 written, both Mr. Gallard and myself have discovered, almost 

 simultaneously, the cocoon of Ithone. Thus the discovery of the 

 pupa and pupal skin free in the earth, last year, led to an 

 erroneous conclusion, and is only to be explained on the supposi- 

 tion that the pupa was found while on its way up through the 

 sand. All statements in the present paper about the pupa lying 

 free in the earth should be deleted. The cocoon and pupa will 

 be fully described in a future paper. — R. J. Tillyard.
