BIBLIOGRAPHY OF THE COCCOIDEA, SECOND SUPPLEMENT 3 



names of insects in titles will assist nontaxonomic librarians and 

 bibliographers. 



We are greatly indebted to numerous coccidologists and others 

 who have provided reprints of articles and have assisted in ob- 

 taining obscure publications, in furnishing translations, and in 

 many other ways. We thank all these individuals and especially 

 M. B. Callaway, formerly of the Systematic Entomology Labora- 

 tory, and personnel of the National Agricultural Library (all 

 U.S. Dept. Agr.) ; G. De Lotto, Plant Protection Research Insti- 

 tute, Pretoria, South Africa; and D. J. Williams, Commonwealth 

 Institute of Entomology, London, England. Without the unfailing 

 cooperation of many persons this supplement would have fallen 

 far short of our intent.
