REVISION OF COELIDIIXAE 9 



script, for pointing out the correct author of the subfamily Coelidiinae, and for 

 making it possible to publish this work in the Bulletin. My sincere appreciation 

 is expressed to Dr Carlo Vidano, Istituto di Apicoltura e Bachicoltura, Universita- 

 Torino, Turin, Italy, for his kindness and for making arrangements with Marquis 

 Marco Spinola, to whom I am also grateful, for allowing me the rare privilege of 

 examining the Spinola collection of Homoptera in the Spinola Castle, Tassarolo, 

 Allesandra Province, Italy. 



Sincere appreciation is expressed to Miss Sieglinde Neuhauser, who made nearly 

 all of the genitalic preparations of hundreds of specimens, and to Mrs Dana Ycnsen 

 and Mrs Wilma Findley, who prepared the illustrations and plates. I am also 

 indebted to Mrs Jean Whitehouse, who typed and proofread the manuscript.
