AMERICAN COLEOPTERA. 197 



Index to the Coleoptera described by J. L. L.eConte, 91. D. 



BY SAMUEL HENSHAW. 



The following list prepared at the suggestion of Dr. Horn owes much 

 of its completeness to the assistance of that gentleman and Dr. LeConte, 

 both of whom kindly examined the manuscript and have added con- 

 siderable synonymy as yet unpublished. 



To Dr. Sharp of Thornhill, Scotland, I am indebted for a similar 

 service with the Dytiscidae. 



It may be noticed that a number of the names adopted are of 

 more recent date than those suppressed, (as Evarthrus vagans G-349 

 = E. Engelmanui 17-228, Anisodactylus similis 14-1 8;> = A. semi- 

 punctatus G5-83) ; the reason for this is that the retained name is 

 either more expressive or one that has come into general use, and as 

 both the retained and suppressed names were proposed by the same 

 author no favoritism is shown.* 



As a rule Catalogue names published without descriptions are not 

 included. 



In order to avoid confusion a list of the species described by Major 

 J. E. LeConte is appended. 



In the following pages the first number after a generic or specific name 

 refers to the title in the accompanying list, the second the page. When 

 a species was described under a difterent generic name irom that used 

 here, the original name follows in brackets. 



The types are for the most part in Dr. LeConte's cabinet. When 

 a name is followed by * the type is with Dr. Horn, when by * * with 

 Mr. Ulke, other exceptions will be referred to by note.

 places in the synoptic works of Drs. LeConte and Horn, and are, consequently; 

 not suggested here for the first time.
