in 1873. Two of the most important papers fixing Elaterid geno- 

 types are those of Thompson, Scandinavian Coleoptera, 1859, and 

 Reitter in Bestimmung, Tabelle, 1905. Other writers from time to 

 time have incidentally indicated the type of polybasic genera, and 

 the more recent writers have often indicated the types of genera 

 erected by themselves. 



This catalogue presumes to be complete up to January 1, 1919, 

 and omissions and corrections will be gratefully received. The 

 genera erected for fossil species are included in the general catalogue 

 and are indicated by footnotes. The arrangement is strictl}^ alpha- 

 betical, each genus being printed in heavy type, and followed by the 

 name of the author. Generic names that are not valid are set off by 

 brackets. Prior use of the same name is indicated by the name of 

 the author previously using the name and the date of publication, 

 following the present citation. If the name was used in some family 

 other than the Elateridae, this use is indicated. Thus Oxystemus 

 Latkehxe, not Godet 1833, Histeridae, means that the Elaterid 

 generic name Oxystemus used by Latreille had been previously 

 used in 1833 by Godet for a genus of Histeridae. The second line 

 is the date of publication of the name of the genus under con- 

 sideration, followed bj' the bibliographical reference and the number 

 of species originally included. Where genera are erected with- 

 out species and later valid species included, the bibliogi-aphical 

 reference to the original description and also to the publication in 

 which the first species are included in this genus are both given. This 

 has been done in order to make this work acceptable to both those 

 who accept genera without species and to those who do not. When 

 isogenotypic synonymy occurs, this is indicated in a note. The geno- 

 type is italicized and the rule followed in selecting the type is indi- 

 cated in parentheses. The bibliographical reference following the 

 genotype is to the publication in which the species was described as 

 recognized by the author of the genus. In many cases an author 

 refers to a species as described by Fabricius, while the species was 

 originally described by Linnaeus; but as this involves synonymical 

 reference the Fabrician description and the insect to which it applies 

 is recognized as the type of the genus. 



In selecting these types the author has strictly followed the rules 

 of the International Zoological Congress. In the more minute de- 

 tails the code as prepared by Messrs. Banks and Caudell has been 

 followed, and the writer wished to express his appreciation of the 

 kind assistance given bj' both of these gentlemen in interpreting 

 nomenclatorial codes. At the end of the paper the genotypes are 

 arranged alphabetically to facilitate the selecting of types for new 

 genera. The writer has examined the descriptions of all the genera. 

 Xo attempt has been made to discuss generic synonymy except where
