FOREWORD 



It is with a great deal of pleasure that the Smithsonian Institu- 

 tion pubHshes this volume of original contributions in honor of 

 Dr. Robert Evans Snodgrass. Dr. Snodgrass is universally ac- 

 knowledged to be among the foremost insect morphologists of 

 our time, and his scholarly and painstaking work in his field has 

 won for him the admiration and respect of his colleagues through- 

 out the world. This feeling is expressed in one way or another 

 by each of the authors of the papers specially written for publica- 

 tion in this volume. 



Although Dr. Snodgrass has never been on the active staff of 

 the Smithsonian, nevertheless he saw fit as far back as 1919 to 

 offer the results of his researches to the Institution for publication. 

 The Institution on its part was more than willing to undertake 

 their publication, for original researches and the publishing of the 

 results thereof constitute one of the principal means by which the 

 Smithsonian implements James Smithson's mandate for "the in- 

 crease and diffusion of knowledge among men." 



The arrangement has continued up to the present time, and over 

 the years the Institution has published in its Miscellaneous Collec- 

 tions series a large number of Dr. Snodgrass's scientific contribu- 

 tions, as well as several popularized papers on insects in its Annual 

 Report Appendixes, which are intended to foster an interest in 

 science among the general public. An assessment of the significance 

 to science of these contributions will be found in the biographical 

 sketch appearing elsewhere in this volume. 



In 1953 Dr. Snodgrass was appointed an Honorary Collabora- 

 tor of the Smithsonian Institution, which title he continues to hold 

 to the present time. At the age of 84 he is actively engaged in 

 further research in his field, and it is hoped that many more of his 

 basic contributions to insect morphology will appear under the 

 Smithsonian imprint.
