COLEOPTERA OF LATIN AMERICA 9 



Americana, Genera Insectorinn, Leng and Mutchler list of West Indian 

 Coleoptera and supplement, Costa Lima catalog of insects of Brazil, and 

 numerous smaller lists or monographs of the Coleoptera of Baja Cali- 

 fornia, the Isle of Pines, the Falkland, Juan Fernandez, and Galapagos 

 Islands, and papers on certain families from parts of our region. 



Errors appearing in the Coleopterorum Catalogus have of course been 

 copied, unless they were by luck discovered through comparison with 

 other sources. The nmnber of these errors incidentally caught and cor- 

 rected is so large that it is certain that many more still exist undetected. 

 It is hoped that few additional errors have been added in the present work, 

 but time has permitted only a minimum of checking. 



"VVliere obvious errors or omissions were detected in the basic list de- 

 scribed above, additional research was necessary to provide a correct 

 solution. Many hundreds of these points have been investigated. 

 Wherever the present list differs in details from the Coleopterorum Cata- 

 logus, the compiler may be presumed to have made some examination of 

 the facts, but not always involving examination of all original sources. 



This revised manuscript, brought up to date as nearly as possible, has 

 then been examined by the specialists at the U. S. National Museum and 

 the U. S. Department of Agriculture (as listed below). Many important 

 suggestions, additions, and corrections have been made by these men, 

 but it must not be assumed that they accept authority for the list as 

 published or necessarily agree with the compiler in all points involved. 

 In some families this examination has been cursory, but in others there 

 has been substantial revision from the unpublished knowledge of these 

 collaborators. 



The compiler is greatly indebted to Dr. Edward A. Chapin, Curator of 

 Insects at the U. S. National Museum, for much advice and help in the 

 development of the general plan of the checklist, for numerous personal 

 researches into individual problems, and for examining the manuscript 

 of those families included in his specialties. The editors of the Smith- 

 sonian Institution and the U. S. National Museum, W. P. True and Paul 

 H. Oehser, respectively, have contributed largely in developing a satis- 

 factory style and in settling numerous points of importance in the prepa- 

 ration of the manuscript and the printing of the checklist. Much credit 

 is due to Mrs. A. C. Willis and Mrs. Marguerite Poole, of the Smithsonian 

 Institution, for their large amount of accurate work in preparing the basic 

 lists from the primary sources and in typing the final manuscript. 



The Coleoptera specialists of the Division of Insect Identification and 

 Classification of the U. S. Department of Agriculture (working in the 

 U. S. National Museum) have been exceedingly helpful. In particular, 

 H. S. Barber, M. W. Blackman, L. L. Buchanan, W. S. Fisher, and J. M. 

 Valentine have examined parts of the manuscript and made numerous 

 valuable additions and corrections. To all these the compiler expresses 

 his sincere appreciation and thanks.
