FOREWORD 



Very nearly 20 years ago I bought, on the advice of an elder col- 

 league, a copy of Snodgrass's "Principles of Insect Morphology." I 

 had already been interested for many years in the insects, but Snod- 

 grass's book opened for me a new horizon in their study. By laborious 

 reading in a language with which I was not then familiar, I learned 

 many things about the structure of insects and how they function as 

 living mechanisms, and conceived an unlimited admiration for the 

 author of the book. 



Later I sought an opportunity of going to the States to study en- 

 tomology, and for some time enjoyed the rare privilege of being the 

 disciple of the author of that notable book. What for years had ap- 

 peared to be an unattainable Utopia came true, and for many months 

 I worked in morphology under his kind and patient guidance. If the 

 reading of his books had made me admire Snodgrass, working by his 

 side awakened in me the warmest affection for the kind and unas- 

 suming man I found him to be. 



Through the years, after my return to Uruguay, Snodgrass has 

 continued by his personal letters to encourage me in my work, to give 

 advice, and by his published works to enlighten my mind in scientific 

 matters. This little work on the anatomy of a South American insect 

 is intended as a contribution to a volume to be dedicated to Snodgrass. 

 The contents of this modest contribution may not prove to be worthy 

 of the circumstances, but, being a piece of my own personal work, 

 is the best I can offer to thank and honor Dr. Snodgrass.
