PREFACE. 



When the "Check List of Coleoptera" was published, a series of 

 supplements was promised, to contain the additions and corrections 

 which might be required hy later studies. The interval of nearly seven 

 years which has elapsed since the issuing of the original list, has been 

 one of great activity in Entomological matters, so that the old list has 

 become in a great measure obsolete. 



In the present list I have endeavored to indicate as far as possible, 

 without reprinting the entire list, the numerous changes in synonymy 

 and additional species which are indicated by the recent studies. 



As is well known, numerous species were omitted in the former 

 list, some by accident and others because they had not been identified 

 by modern authorities, or were considered by Mr. Crotch to be 

 synonyms of other species. Many of these species have since been 

 identified, others still remain unknown, and I have endeavored to in- 

 sert all of these which seem entitled to rank as distinct species. 



The following explanations will, I trust, render the list intelli- 

 gible : 



Genera which wei'e not in the old list are indicated by having the 

 authority printed after them. 



If the name of a genus in the "Check List" is to be changed, it is 

 indicated in one of the following ways : Either the new name is printed 

 in full-face type, with the former name beneath in italic, as on p. 7, 



Tecnophilus Chd, 



Thilotfcniis^ 

 which indicates that Philotecnus is a synonym of Tecnophilus, or as 

 on p. 16, 



For Choleva read Prionochseta Horn, 

 which means that the species known as Choleva belongs to the (in this 

 case new) genus Prionocha'ta, but indicates nothing as to the validity 

 of the former genus. 



The proper place of a new genus is indicated as on p. 7 : "after 

 419 add Onota Chd." When the name of a new genus follows im- 

 mediately after the additions to another, it of course belongs next to 

 that genus, as on p. 11, AnacyptuS comes next to Hypocyptus.
